Physiology And Homeostatsis

Homeostasis is a characteristic of life in which all Living things maintain. some of the traits of Homeostasis are perspiration and some form of breathing and other natural body functions. An example of a negative feedback mechanism is a Thermostat If the heat is turned on and is set at 80 degrees the heat is turned on, If the temperature drops below 80 degrees, After the heater heats the house to 80 degrees, it shuts off keeping the desired temperature. An example of a positive feedback system is when a baby is born. while the mother is in labor, a hormone is released that boosts and quickens her contractions. The more contractions causes more of that Hormone to be let out and it continues to goes on until the

3. Name the structure that is a double fold of peritoneum and holds the small intestine to the

There are many kinds of body systems, working together to create a functioning body. Different body systems work with certain body systems, but all work together. Like, nervous system and muscular system, circulatory system and respiratory system, and so on.

The stomach is an organ that is part of the digestive system. The stomach is located in the upper left part of the abdominal cavity, below the diaphragm and next to the liver (Stomach, 2013). The inner walls of the stomach contain small pores called gastric pits. The gastric pits contain cells that secrete chemicals that aid in the digestion of food (Nguyen, 2015). In this essay, I will discuss the different cell types of the stomach, how they work together to provide the overall function of the stomach, why each organ requires different cell types, why the stomach can’t be comprised of just one cell type, and the advantage of having different types of cells.

The esophagus receives food from the mouth after swallowing and then delivers it to the stomach. The stomach holds food which it is being mixed with enzymes which continue the process of breaking down the food into a useable form. When the contents of the stomach are processed they are released into the small intestine. In the small intestine food is broken down by enzymes released from the pancreas and bile from the liver, the food is moved through and mixed with digestive secretions. The small intestine is made up of three segments the duodenum, jejunum and the ileum, the jejunum and the ileum are mainly responsible from the absorption of nutrients in to the bloodstream. These contents start out semi-solid and end in a liquid form after passing through the organ. Water, bile, enzymes and mucous change its consistency, one the nutrients have been absorbed it then moves onto the large intestine. The large intestine connects to the rectum and is specialised in processing water so that emptying the bowels is easy.

Explain what they are, their functions and where they are found. Then go into detail about two organs, with their functions, what tissues they are made of and where they are found in the body.

All cells group together within the body to form tissue, a collection of similar cells group together to perform a specialized function. There are four primary tissue types in the human

The relationship between the structure and function of the Outer Wall Intestine cells is, in the structure, the fibers are short and not striated, while since the cells are “smooth cells” this allows the function of the cells to be involuntary and is composed in the lining of the organ. The contractions of the cells allow the organ to keep blood, fluids, and necessary nutrients to flow throughout the organ.

Tissues are groups of cells, which are placed together to achieve a common function. There are four main types of tissue: Epithelial, connective, muscle and nervous. Most of these tissues are found in our bodies, however the epithelial tissue is covered all over the surfaces of the body.

5. Organ system level- Organs that work together to accomplish a common purpose make up an organ system.

What are the three sections of the large intestine and what roles does each play in digestion or absorption?

Organ system is a group of organs that work together to perform a certain task.  Humans

The first type of tissue found in the human body is epithelial tissue. These types of tissue are found covering the whole surface of the body, lining of cavities, hollow organs and tubes. The cells a very closely packed and are arranged in one

oes the human body need all organs or organ systems to survive? How do the systems work together? The paragraphs are about how the Organ Systems work together. They will also be on how they can't work properly without them and what ones we necessarily need.
