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. All living things, including you, are made up of cells. Cells are the simplest and most basic units of all living organisms. Cells are organized together to make tissues. A tissue is a group of cells that are similar and work together to perform a specific function. Tissues are organized together to make organs. Organs are two or more tissues that work together to perform a specific function. Organs are organized together to make body systems. A body system is a group of organs that work together for one purpose. The difference between a tissue and an organ is a group of the same cell makes a tissue and a group of different tissues makes up an organ. Your body systems all work together to make your body function properly. …show more content…
There is the nervous, endocrine, skeletal, muscular, digestive, excretory, circulatory, immune, and respiratory system. The nervous system controls and coordinates the activities of the body systems, the endocrine system helps regulate growth, the skeletal system provides a framework to support and protect the body, the muscular system works with the skeletal system to cause movement, the digestive system breaks down and digests food, the excretory system filters liquid waste products from the blood and eliminates them from the body, the circulatory system transports and distributes gases, nutrients, and hormones throughout the body, and the respiratory system exchanges oxygen from the environment and carbon dioxide from the
The body is composed of cells, which form the basic unit of life. Unique cells found in the body are the stem cells. These cells are biological cells that are not specialized for particular functioning in organisms. They can be distinguished since they have the ability to differentiate or divide into multiple body cells, and their ability to replicate self. They are unique in the way they can renew themselves by undergoing cell division when inactive for a long period. It is also possible to induce stem cells to organs or tissue cells under some conditions. When the cells divide, they replenish the cells in a living organism. They serve as an internal system that repairs and replaces the tissues that are worn out.1 Dividing cells may remain as stem cells or become specialized in their functions, for instance red blood cells, brain or muscle cells.
All organ system work together; in order to keep and support the conditions that the cells, tissues, and organs need to function properly. Each organ system has an important function in the body. There is one system that is not as well known as other; it is the integumentary system. Most people know the organs of the integumentary system, but they do not know that these organs work together to form this system.
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 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.
All 4 systems, cardiovascular, digestive, respiratory and excretory all aid the body in maintaining homeostasis through the exchange of gases and molecules throughout the body. The respiratory and cardiovascular systems work together to insure all parts of the body have an adequate oxygen supply for every cell to carry out cellular respiration. Deoxygenated blood is pumped from the heart to the lungs where it captures oxygen molecules and transports them from the lungs to around the body until the blood is deoxygenated again. Both systems are also used to remove CO2 from around the body by following the opposite path and exhaling it as waste. The cardiovascular system also works with the digestive system to transport molecules and nutrients needed for cellular respiration. In the digestive system complex molecules are broken down into smaller, simpler molecules like glucose. These molecules are then
The Biomedical Model constitutes the absence of disease, pain and defect of the body (Fanany, 2012). (Baum, 2012) describes the Biomedical Model in reference to the human body “like clockwork”. He believes that the body is like a machine. Every individual part that fits together must be able to function interpedently for the rest of the body to work – just like a clock.
“Alarm sounds. Firefighter Johnson hears the bell and bolts out of bed. His brain directs the release of adrenaline into his system, making him more alert more quickly.” This is an example the nervous system telling the endocrine system to release adrenaline, a chemical that makes the body more alert. The body is trying to help him complete his task by making his senses sharper because he is in a dangerous situation. “As Johnson wonders what he will find there, his pulse quickens and his breathing gets faster.” This is the brain (nervous) telling the heart(circulatory system ) and lungs( respiratory system) to start producing more oxygen so the body can be agiler and move to a danger. This is the circulatory system and the respiratory system
...acts and relaxes to mix and digest the food. The respiratory and digestive system work closely together to make energy. The respiratory system brings in the oxygen needed to make energy and the digestive system obtains the nutrients needed to make energy. The digestive system has the closest relationship with the circulatory system. As the digestive system breaks down food, it absorbs nutrients into the blood stream. The circulatory system then transport the nutrients attained through the digestive system to the rest of the body. In a more obscure way, the nervous system, specifically the medulla, controls all of the involuntary actions made throughout the digestive process. Finally, the endocrine system release many hormones that affect the digestive process. These hormones single when certain enzymes should be used and when certain nutrients should be absorbed.
In the conclusion, many people opinion would disagree say the heart was the most important part of the body. They didn’t know the only way the heart will working is by the brain, and the neurons are sending signals. Our body are like light switch your turn back on and off, plus you could even restart your body. In other cases, the brain is the most tangled part of the human body. It is the center of alertness and also rules all voluntary and involuntary movement and bodily functions. It can communicates with each part of the body throughout the nervous system, is a network of channels that carry electrochemical signals.
Every organ in the human body is composed of one or more tissues. The study of these tissues is known as histology. It is because of histology that the structure of organs can be researched and understood. Since organs are composed of tissues, it is important to understand each tissue type, their structure, their location, and their functions to better understand how each organ operates within the human body.
The Cell, the fundamental structural unit of all living organisms. Some cells are complete organisms, such as the unicellular bacteria and protozoa, others, such as nerve, liver, and muscle cells, are specialized components of multicellular organisms. In another words, without cells we wouldn’t be able to live or function correctly. There are Animal Cells and Plant Cells. In Biology class the other day we studied the Animal Cell. We were split into groups of our own and we each picked a different animal cell slide to observe. My group chose the slide,'; Smeared Frog Blood ';.
The muscular system is a very important part of the human body. It has many components and functions, and is the source of the body’s movement. There are roughly 650 muscles in the human body and are different types of muscles. Muscles can either be voluntary or involuntary which means controlled or uncontrolled movement. Muscles have many reasons and in this paper you will widen your knowledge of muscles and their functions as well their diseases and how they help maintain the body.
Cells are some of the smallest organisms around. All living things consist of cells, and yet they are invisible to the naked eye. Cells are the basic structural and functional units of life. Cells are made up of many different parts which allow them to function properly.
The human body is very complex. It is like a job. You have to do a million things in one day to make it through the day. The body uses nine systems to do all of those jobs. They all have separate functions, but some work together. Each system is also made up of organs. There are many ways to care and protect the systems from the many different problems they can have. There are also many interesting facts about each system.
The Cardiovascular system, also known as the circulatory system, is the organ system that allows blood to circulate and transport nutrients like amino acids and electrolytes. As well as transporting oxygen, hormones, blood cells, and carbon dioxide to provide nutrients to the body and help fight against diseases, keep body temperatures steady alongside the pH, and maintain homeostasis. A few different organs make up the cardiovascular system but the heart is the main one. The hearts job is to pump fresh, oxygenated blood through the body and out the veins to reach the other organs. Another highly important organ in this system is our blood vessels, allowing blood to flow quickly from one area to another and back to the heart. We have three
