The human body has 206 bones, which the bones in the human body system is used for; a framework and support the body, allows for internal organ protection, more efficient body movement, produce red blood cells in the bone marrow, and stores minerals. There are two different types of skeletons in the body which are axial; with the skull, vertebral column, ribs, and the sternum and the appendicular; with the arms, legs, shoulder, hip, wrist, ankles, finger, and toes. There are also joints in the skeletal system where two or more bones meet which include; bones, ligaments, muscles, tendons, and nerves. Bones act as levers and magnify the force provided by muscles contraction. Tendons are thick bands of connective tissues to attach muscles to bones. …show more content…
Blood is composed of fluid, cells, fragments of cells, and transportation of nutrients, oxygen, carbon dioxide, hormones, antibodies, urea, and heat which are produced by red bone marrow. Blood transports oxygen and carbon dioxide but lacks a nucleus, contains hemoglobin, iron containing protein, and oxygen is loosely connected to hemoglobin in blood cells. There are also white blood cells which are large in size and contain a nucleus and there are several different types of white blood cells which include B Cells and T Cells; Basophil, Eosinophil, Neutrophil, Monocyte, Defense & immunity, Platelets, Cell fragments need for blood clotting. There is also plasma which transports red and white blood cells, platelets, nutrients, enzymes, hormones, gases, and inorganic salts. Platelets attach to the damages area and then clotting happens. These platelets are made in bone marrow. There are three types of blood vessels. One type is called an artery and it is large and ha high internal pressure with thick walls and no internal muscular valves. The next type is capillaries which carry blood away from the heart, they are microscopic, with only one cell thick walls, no internal valves, allows for nutrients and gases to diffuse easily between cells and tissues, and forms a dense network that allows for blood to reach all over the body. The next type of blood vessels are vein which carry blood back to the heart that are not …show more content…
There are many different infectious organisms that can harm the human body so antigens are produced by the bodies’ immune system to help fight the infectious organisms. There are also antibodies that are produced by the body and target specific viruses and bacteria to get rid of them. Each different antibody is cloned when the virus or bacteria is identified to fight it off. There are also different forms of defense which include skin, mucus membranes, physical and waterproof barriers, and cells shed so microbes don’t colonies. Mucus is important in trapping and not letting and harmful organisms get inside of the body mucus is also constantly getting produced to help keep the body safe. White blood cells help to engulf the harmful organism and when they get inside of the body that called phagocytosis. Macrophages also remember whether the cell is elf or it’s not itself based in proteins. There is also an inflammatory response to when there is an injury or infection so there is blood flow that cases redness and heat. When there is a more widespread infection inside of the body the white blood cells release pyrogens which cause the body temperature to increase. There are specific types of antibodies that are produced to be able to fight against the infection; these cells are called A lymphocytes and B lymphocytes. These antibodies will circulate inside of the blood stream to find the infection and help eliminate it. There also some
The B cells, T cells, Macrophage, and Antibodies are all a very large part of the immune system. There are two types of T cells, killer and helper T cells. Killer T cells find and destroy cells infected with bacteria, and helper T cells control the activity of other cells in the immune system. Then, B cells are considered the “clean up crew,” attacking any bacteria or viruses the T cell left behind. They also make antibodies, which are essential for trapping invading viruses and
The job of the immune system is to keep “foreign” invaders out of the body, or if one gets in, to seek it out and kill it. These foreign invaders are called pathogens, which are tiny organisms that can cause an infection in the body. Pathogens can be bacteria, parasites, and fungi (http://www.niaid.nih.gov/topics/immuneSystem/pages/whatisimmunesystem.aspx).
As you can see by the diagram, the muscles cover the entire body as does the integumentary system. They are responsible for movement. They are attached to the bones (skeletal system) and there are nearly 700 different ones. Each is made up of the muscle tissue, blood vessels, tendons and nerves. Each has a specific purpose. For example, the leg muscles assist in moving and bending the legs. The muscles make up nearly half of a person’s total body weight.

First of all, there are specific mechanisms, cells involved and stimulus for antibody production that need to be delineated. The specific mechanisms are activated in response to a specific pathogens. They are also active against a specific pathogen. Specific mechanisms also prevents reinfection gain immunity. The humoral and cell-mediated immune defense mechanisms induced against an infectious agent are specific in nature, i.e. the specific immune mechanisms act only against the microbe against which the responses were induced and not against other microbes. The stimulus for antibody production is an antigen, which is a substance such as bacteria or other agents that the body recognizes as ‘foreign.’
The human body is a complex machine made of many parts that work together. When these parts work together, they allow you to do amazing things, such as do a backflip, remember to do your essay, or play a video game. Each part has a role to play, and each part contributes to the functions of the other parts of the body.
This paper explores the human skeletal system including its purpose, structure, and the common diseases and disorders that affect it. The human skeleton has a unique design meant to provide structural support and act as a reservoir for minerals in the body. The paper also expounds on the components of the skeletal system such as the axial and appendicular skeletal systems. The axial skeletal system is tasked with supporting the head, neck, and trunk. It is composed of the cranium, vertebral column, the rib cage, and the thoracic cage. The appendicular skeletal system, on the other hand, is composed of the limbs, upper and lower parts of the body like the femur, carpals, tarsals, and humerus. The body’s hardest parts are components of the skeletal
The process of blood coagulation relates to the term haemostasis. Haemostasis is a process of stopping the flow of the blood. When a blood vessel is damaged or injured, the platelets in the blood become attached to macromolecules which are located in the endothelial tissues and form a haemostatic plug. Coagulation consists of platelets and protein. These platelets form the primary layer which creates the haemostatic plug. This process protects the body from infection and disease as the fast-healing motion reduces the risk of pathogens and micro-organisms entering the body through the damaged skin and blood
The skeletal system is made up of 206 bones, as well as tendons, ligaments, and cartilage that connects them. The skeletal system has six major functions. The first function is that it supports and provide structure, the second is it facilitates the movement, as the muscles contract and shorten they pull on the bones and move them. The Skeletal system also acts a protector to all the of the soft tissue organs, they can also move to be used as a defense of the body from outside forces. The skeletal system also helps create red bone marrow, that is a soft connective tissue surrounded by the hard walls of some bones that produce both
Lymphocytes travel through the body through blood vessels, or through lymphatic vessels that have a similar structure to veins. Cells and fluids can be exchanged between the blood and the lymphatic system to help the body find microbes. The lymphatic system transports lymph, which contains white blood cells,
The human skeletal system is composed of 206 bones. The skeleton provides support and stability, gives our bodies shape, act as a
The human immune system is a complex network made up of tissues, proteins and special cells which aim to stop humans from becoming sick or infected from a germ, bacteria or virus. The immune system generally does its job very well and often as not we don't even know when we have been exposed to a germ of virus, however with certain viruses that we have had no previous exposure to, when we do come into contact with them our immune system can become overwhelmed resulting in us becoming sick. This is where vaccines come into the picture, they work by preparing the immune system for any possible exposure to a virus so that the immune system knows how to combat the foreign invader. An important cell when looking at the human immune system is the white blood cell [23] “which comes in two different basic types that combine to seek out and destroy disease causing organisms,” the two forms are phagocytes which destroy invading organisms and lymphocytes which essentially remember the invader so that the body is able to recognize it the next time the it is exposed to the invader and so the immune system will be able to respond faster. An overview; when the body is exposed to a virus the lymphocytes respond by producing antibodies which attach and destroy the antigen, these antibodies remain in the system so that the next time the antigen is encountered the antibodies are there and waiting to destroy it before infection
Blood has three types of cells the white blood cells, red blood cells and the platelets. All these three types of blood have something different job to do. For the white blood cells, they are the once that fight infection. Red blood cells are the once we have more and the once that carry oxygen all over our body. The platelets are blood to clot.
I will be investigating Human Blood as my specific tissue and giving an overview on the location, characteristics, and the benefits it has to the human body. Blood is extracellular matrix that is consists of plasma, red blood cells, platelets, and white blood cells. Blood is located within the capillaries/veins/arteries of the human body, which are blood vessels that run through the entire body. These blood vessels allow the blood to flow smoothly and quickly from the heart to distinct parts of the human body. The unique parts of human blood all work together for a purpose: the Red Blood Cells(erythrocytes) transports oxygen throughout the body, White Blood Cells(leukocytes) play a part in the bodies immune system, Platelets(thrombocytes) assist in creating scabs,
In the event of injury certain mast cells in the connective tissues send out histamine molecules. That cause vasodilation, developing redness and heat at the site of infection. The heat helps bump up the cells metabolic rate so that they can repair quickly. While histamine and other chemicals of inflammation increase the permeability of blood vessels. Then triggering capillaries to release protein-rich fluids. Then because of this swelling takes place, the leaked proteins assist the blood in clotting and forming a scab. While the lymphatic system is cleaning the remaining fluid to be filtered to go back into blood. The openness of the capillaries make it easier for phagocytes to escape. They will then come to the site to seize the pathogens and clean up dead cells. Since neutrophils were the first to arrive first they are starting to die out near the end. Interferons are then present and they alert and protect the surrounding cells that have not yet been infected. This then allows antiviral proteins to block viral reproduction. Therefore, when leukocytosis occurs after the virus starts to heal they are then alerted by the capillaries to come. The neutrophils then bind to the capillary walls near site of virus and squeeze through the vessel to start working. Then monocytes turn into macrophages replacing the neutrophils, cleaning up the rest of the
