The human body is an amazing thing made up of many different parts. These parts are cells, tissues, organs, and organ systems. For starters, one type of cell makes up one type of tissue. Next, two or more types of tissues make an organ. Then, a few organs working together make an organ system. 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. There are millions of these cells inside the human body, and each has a different type of responsibility, or function. There are an infinite amount of cell types, and a few examples of these types are: 1) muscle cells, 2) nerve …show more content…
Some examples are the circulatory, the excretory, the muscle, and the digestive systems. For example, the digestion system is an organ system that digests the food a person eats. Some organs in the digestive system are the esophagus, rectum, stomach, liver, gall bladder, pancreas, large intestine, small intestine, and appendix. The digestive system is very important because without it, organisms would not be able to digest food. Food would just sit inside the body or go through it without the body taking any energy for fuel. The digestive system is located around the stomach area. Along with the digestive system, many other organ systems all work together to create an organism. An example of this would be if a person eats a sandwich and then goes for a run. During the run, the circulatory system helps the body breathe, the muscle system helps the bones move, and all the while the digestive system digests the food. Later on, the excretory system gets rid of the waste, or food that the body can’t use for nourishment. All of these organ systems need to help to make up the

First the food enters the mouth and then goes to the esophagus where it is pushed down to the first part of the stomach. The first part of the stomach is the cardiac stomach which holds chitinous teeth which grind up the food even more than it has been in the mouth. Then it goes to the pyloric region which is the second part of the stomach where nutrients are sucked out of the food.
Digested molecules of food, as well as water and minerals from the diet, are absorbed from the cavity of the upper small intestine. Most absorbed materials cross the mucosa into the blood and are carried off in the bloodstream to other parts of the body for storage or further chemical change. As already noted, this part of the process varies with different types of nutrients. 5. 2) Page B13, and #1-4 1.
The proper functioning of one system relies on the proper functioning of the other system. In other words, the digestive system needs to be in good working order to support the functions of the cardiovascular system. An example of the digestive and cardiovascular systems interrelating is: the first step in digestion of fat is to dissolve it into the intestine where bile acids produced by the liver dissolve the fat into fatty acids and cholesterol. The bile acids join with the fatty acids and cholesterol and vessels then carry the changed fat to the veins of the chest, and the blood carries the fat to storage in different parts of the body.
The stomach is a very important part of the digestive system. It is a j- shaped muscular organ that acts as a bag or sac to collect churn food with digestive juices. When the stomach is filled with food the rugae stretch out, and disappear. The food mixes with hydrochloric acid and other gastric juices to form a liquid mixture called chyme, which then passes through the remaining portion of the digestive system. So this means to me that when you eat something it goes to the stomach and is mixed with acids that breaks it down and dissolves the food.
The digestion tract for earthworms is much like the crayfish. Food enters the mouth and gets pushed down into the esophagus by the pharynx. Next in line is the crop; an organ very similar the cardiac stomach. In the crop food in held until it is moved into
The digestive system is a system that allows you to gain energy from the food you eat. The digestive system is made up of the mouth, the esophagus, the epiglottis, the stomach, both the sphincter and the pylorus, the liver, and finally the small intestine and the large intestine. The mouth breaks down the food into smaller pieces and then the tongue moves the chewed up food to the throat. Then the food travels down the esophagus into the stomach. When you swallow the epiglottis moves the food down the esophagus and not the windpipe.
The inquisition and philosophies between the mind and body have been being discussed for hundreds of years. Whether or not we our minds have a practical influence on our body. Or human minds are of its own entity and contain a soul that constitutes how we act and function. Dualism constitutes that the mind and body are not identical and therefore the effect of one does not influence the other. Many philosophers believed in the concept of dualism.
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
She states : “There are over 200 different types of cell in the human body, all with different jobs to do. The stem cells role is to replace other cells when they die as a result of disease, injury or just general wear and tear. For example a skin stem cell will replace dead skin cells. Our body also has stem cells for tissue like muscle and blood. They can be found in places like the skin or bone marrow.
Almost half of a human 's body weight is composed of muscle. There are three distinct types of muscle tissue: cardiac muscle, skeletal muscle, and smooth muscle. Each of the muscle tissues have different structures, properties, characteristics, and roles in our body. Properties of muscle tissues include excitability, contractility, extensibility, and elasticity. Contractility is the ability to shorten, which causes movement of the structures to which the muscles are attached.
Macromolecules are essential nutrients that our body needs in order to function. We cannot manufacture theses nutrients, so we must obtain them from our environment. Macromolecules are an essential source in our bodies and they help keep us alive. We call theses building blocks of life carbohydrates, lipids, and proteins. Carbohydrates are made up of sugars, such as glucose, and fructose.
The Digestive System The digestive system is a system consisting of the mouth, oesophagus, stomach, gallbladder, small intestine, large intestine, the rectum and the anus. The functions of the digestive system are: • To break down food particles into molecules for digestion • To absorb into the bloodstream the small molecules produced by digestion • To eliminate un digested and unabsorbed foodstuffs and other waste products from the body The full digestive process begins at the mouth. The food enters the mouth and is chewed.
