White Blood Cells
Everyone has a defense system in their body. They’re called white blood cells. White blood cells are a part of the Immune system and the Cardiovascular System. White blood cells have a structure that helps it function. But sometimes they can malfunction. Everybody needs white blood cells to stay healthy. White blood cells are a large part of the Immune system, and greatly contribute to the
Cardiovascular system. In the cardiovascular system, they act like highways that contain the heart, blood, and blood vessels. Their job is to carry waste products away from the cell, and also carries glucose which makes energy. Blood is used to carry oxygen to the lungs and to other parts of the body. “When Cells break down glucose,

The Nonspecific Immune System is where white blood cells come in. They make sure that no foreign pathogens enter the body.
These white blood cells migrate to fight that infected area. The Specific Immune System is made of T cells and B cells. Both kinds help produce bone marrow. “Memory cells give an animal immunity to future attacks by the original invader”(Padilla et al. 89). The Immune System and
The Cardiovascular System are both key for the white blood cells.
White blood cells are necessary for a human body to keep it healthy. Their job is to be like a superhero that fights off bad infections, diseases, and viruses by creating antibodies. White blood cell are also called leukocytes. They are larger than red blood cells and contain a nucleus and ribosomes. White blood cells are produced by marrow and contained in the veins or blood vessels. They only last about three days, but are only 1% of the human blood system, they are so important. These cells carry nutrients to the cell. They also keep a consistent blood temperature for warm-blooded animals. “There are about 4,000 to 11,000 white blood cells per cubic
Millimeter of the blood in the human body” (Manar). There are five different types of

This can cause a very serious health issue. Certain medicines can also raise or lower the amount of white blood cells that enter your body at a time and can, in worst cases, have heart issues. Myeloproliferative disorder is a disorder that can cause an unhealthy balance of the blood (of all kinds) cells. This disorder can trigger excessive amounts of immature blood cells which could cause serious health problems. One of a disease is Leukemia. In all, these malfunctions happen when the system of checks and balances
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
Red blood cells deliver the oxygen to the muscles and organs of the body.
According to Virtual Medical Centre (2014) the primary function of the blood is to act as a transport, to give the body protection and to help regulate. The blood dissolves gases such as oxygen and carbon dioxide. The blood also transports vital nutrients throughout the body, such as micro-nutrients, fatty acids and amino acids. The flow of the blood helps to regulate the body’s temperature. Also the blood removes wastes material of metabolism. Blood cells (white and red cells) are carried through the body to help with the body’s natural defense, blood clotting and the carry anti-bodies.
The cardiovascular system - The cardiovascular system is responsible for transporting nutrients and removing gaseous waste from the body. It consists of the heart, which powers the whole process, the veins, arteries, and capillaries, which deliver oxygen to tissue at the cellular level. The cardiovascular system carries blood that is low in oxygen away from the heart to the lungs via arteries, where oxygen levels are restored through the air once oxygenated, this blood is then carried throughout the body via arteries, keeping our organs and tissue alive. The cardiovascular system is the workhorse of the body, continuously moving to push blood to the cells. If this important system ceases its work, the body dies.
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).
The Circulatory System is a transportation and cooling system for the body. The Red Blood Cells act like billions of little mail men carrying all kinds of things that are needed by the cells, also RBC's carry oxygen and nutrients to the cells. All cells in the body require oxygen to remain alive. Also there is another kind of cells called white blood cells moving in the system. Why blood cells protect from bacteria and other things that are harmful. The Circulatory system contains vein arteries, veins are used to carry blood to the heart and arteries to carry the blood away. The blood inside veins is where most of the oxygen and nutrients are and is called deoxygenated and the color of the blood is dark red. However, blood in the arteries are also full of oxygen but is a bright red. The main components of the circulatory system are the heart, blood, and blood vessels.
blood stream then the immune system would produce antibodies which could then be used in the
To be able to determine which task the immune system needs to take to fight off the pathogen, it must be able to differentiate between self and non-self-substances. The immune system gets activated by the non-self-substances called antigens. The antigens attach to special receptor sites on defense cells which starts cell processes. If the body has come in contact with the antigen before, it will be able to respond to it more quickly (PubMed Health).
The endothelium is a cell layer that is lined on the interior surface of lymphatic vessels and blood vessels, which are made up of endothelial cells (Dorland, 2012).
The immune system, which is composed of cells, proteins, tissues, and organs, is the body’s innate defense against foreign particles that may show to be harmful or infectious to us. Through a series of steps called the immune response, the immune system attacks potentially dangerous organisms and substances that invade our systems. (Durani, Y., 2012) The immune system’s key players include leukocytes, the lymphoid organs, and the lymphatic vessels. Leukocytes are white blood cells that recognize and destroy the harmful invaders. Lymphoid organs (lymph nodes, bone marrow, thymus, and spleen) make and/or store the leukocytes, and lymphatic vessels are a network of tissues that allow for the leukocytes to circulate through blood or the various lymphoid organs. (Durani, Y., 2012)
However, it is only a certain kind of white blood cell that comes out in the non specific response, and it is called a phagocyte - meaning 'cells that eat'. In a process known as phagocytosis, phagocytes can envelope any kind of pathogen within the body and, whilst the pathogen is inside the phagocyte, it can destroy it.
These functions are mineral storage, energy storage, and hematopoiesis. In regards to metabolic reaction, this system has extremely critical functions that are important for the entire body. The cells in bone tissues have chemical processes that produce the energy and substance needed to maintain life. The first function is the role of bone matrix. (Baumie) The bone matrix plays the role as a supply for minerals that are important to the body functions. The two main minerals are calcium and phosphorus. To keep the stability that is needed to support physiological processes the minerals can be released back into the bloodstream. (Baumie) For example, calcium ions are necessary for muscle contractions and flow of other ions that take place in the transferral of nerve impulses. (Baumie) The next function that is important for homeostasis is hematopoiesis. This process is responsible for producing new blood cells in the body. Hematopoiesis has three types of blood cells and they are able to become more than one type of a cell. (Baumie) Cells that are capable of producing more cells of the same type are called stem cells. The stem cells that are a result of hematopoiesis are Pluripotent stem cells, multi potent stem cells, and committed progenitor cells. Stem cells are not the only production from this process. The three types of white blood cells that are also produced
According to this quotation, without white blood cells, also known as leukocytes, we would not be able to survive. White blood cells are our body’s number one defense against infections. They help keep us clean from foreign bacteria that enter our bodies. Statistics show that there are five to ten thousand white blood cells per micro liter of blood, however this number will increase during an illness. White blood cells can differ in many ways, such as, size, shape and staining traits. There are five different kinds of white blood cells that fall into two separate categories. One category is called, granular leukocytes, and the other is called agranular white cells.
The immune system is a fascinating structure it defends the body against foreign invaders like bacteria, viruses and parasites. There are two primary forms that make up the immune system they are, innate and adaptive systems. Both the innate and adaptive system plays a large role in the immune system. The innate is the primary system to defend against foreign materials and the adaptive is the secondary system that responds to specific issues.
Our blood is able to connect all our organs together to create one organism and is able to transport the most vital and important molecules through these blood streams. Hence, blood cells are needed for immune system function and metabolic functions.
