The digestive system is responsible for chemically and mechanically breaking down food and includes organs such as, mouth, esophagus, stomach, small intestine, rectum, anus, and additional accessory organs. These organs all aid in the breakdown of food. Food is broken down mechanically by chewing and churning in the stomach, and chemically by acidic enzymes in the stomach and in the small intestine which receives enzymes from the pancreas that are specifically designed for the breakdown of nutrients. Once the food and nutrients are broken down, the excretory system removes whatever the body decides is waste by filtering blood in the nephrons of the kidneys and turning it into urine which is then collected in the bladder and removed from the body when the bladder is
Next, this semi-liquid mixture enters into the small intestine, where most of the calories and essential nutrients are absorbed by your body. Finally, whatever is left passes into the large intestine and eventually through the colon as it is expelled from the body. Gastric bypass surgery restructures the stomach and intestinal system, resulting in intentional malabsorption and limiting the patient 's ability to eat large quantities of food.
2 POINTS: List the body system that correlates
2. Explain the functions of the respiratory system. Cite the definitions and the differences between external and internal respiration. The respiratory system is responsible for bow we intake air into our bodies and out.
The oxygen is a key ingredient in many cell processes, and without it, the body would fail. Oxygen is required for many processes in the body including making energy. 2- Why did land creatures have to develop a respiratory system in the first place?
In this assignment I will be outlining the structure of the main tissues of two organs in the body and their functions. The two organs I have decided to do is the heart and the stomach. To begin with, the heart consists of many tissues, but the three main types of tissue that make up the heart are; cardiac muscle tissue, nerve tissue and blood tissue. The cardiac muscle tissue is only found in the heart.
As a result of knowing the structure of the organ, we can understand what its functions are and, knowing the functions of the organ, it is easy to
When a figure skater eats food it goes through their digestive system. When the food gets to the large intestine the nutrients is absorbed into the bloodstream. When it gets to the small intestine water is absorbed into the bloodstream. The nutrients and water is then made into energy for the figure skater when
There is also strong acid released by the glands in the lining of the stomach which helps break down food into a more useable form and also aids in the destruction of most ingested bacteria. After the contents have successfully been broken down they are released into the small intestine. The small intestine is a 22 foot long tube that helps to break down the food with enzymes released from the pancreas and bile released form the liver. In this organ the process of Peristalsis is at work, pushing the food further and further through the small intestine towards the colon. These movements are stimulated by the presence of chyme.
DNA has a massive job of keeping you alive. In essence, a microscopic strand of genes support your entire body and life. There are many smaller jobs protein has to accomplish that combine to accomplish the main job of supporting life. To start, DNA codes for proteins and every protein provide an essential biological function. Also, cells make up tissues, organs, and body systems.
Respiratory system is defined as a group of organs that work together in order to allow gas exchange between the internal human body and the external environment,
The muscular system is very important for everyday life. Without it we wouldn't be able to carry out everyday tasks such as writing this paper or tying our shoes or anything. This system also helps us distribute wastes when our body doesn’t need them anymore, which is important because if the wastes build up the toxins will enter your system the wrong way and it will harm you eventuly. This system interacts with the many other systems but the main two are the nervous system and the digestive system. The nervous system is what controls the brain and the brain tells us to move certain parts of our bodies without us knowing it, this is how our involuntary muscles move.
Overview of Immune system The human body provides the ideal environment for the microbes such as bacteria, viruses, parasites and fungi to enter the body. Thus, it is the jobs of the immune system to keep them out by protect the body from the harmful substances. Immune system is when the networks of cells and tissues work together to defend the body against the foreign invaders.(Menche,2012 and National Institute Health,2003). According to the Latin word, immune come from the word immunis which is free or untouched. So it is mean that our body must free from the all pathogens that can lead to the diseases.
Each of the organ systems in your body have a certain function, or job. Working together, all of these organ systems make up an organism. In other words, cells make up tissues, tissues make up organs, organs make up organ systems, and organ systems make an organism. To begin with, cells are the basic unit of life.
(Elwick, J. ,2003) He compared society to the human body. His idea is saying that the organs in the human body are interdependent to each other. If one of the organs of the human body dysfunctions or not working well, it will affect the other organs and influence the whole human body. Similarly, we view society as a complex system, complex system is like the human body.
