Bodies in Balance
In this paper, I’ll be going over 2 main body systems covering the main organs that make up that body system as well as their functions. I’ll also be going over there effect on homeostasis. The two body systems I have chosen are the digestive system and the respiratory system.
The digestive system is designed to turn the food that we eat into nutrients for our body and those nutrients provide energy, growth, and cell repair. (WebMd, 2014) The digestive system is made up of the mouth, throat, esophagus, stomach, small intestine, colon, rectum, and anus. Each part has its’ own unique way of contributing to the digestive process.
Salivary Glands, Pharynx, Esophagus
The mouth is the start of the digestive system, from your first bite digestion starts its process. The chewing mixed with saliva breaks down the food so that the body can absorb and use the food. (WebMd, 2014) Next the food is pushed through to the throat (pharynx) and moves onto the swallowing tube which is the esophagus. Once in the esophagus a series of contractions or moves the food to the stomach but just before it leaves the esophagus the food must go through the lower esophageal sphincter; this is a valve meant to keep food from passing backwards into the esophagus. (WebMd, 2014)
Stomach, Small Intestine, Large Intestine
Upon leaving the esophagus the food then moves into the stomach. The stomach acts like a grinder it releases acids and enzymes that break down food furthers. When it leaves the stomach the food then becomes like a paste and then makes its way to the small intestine.
The small intestine is made up of three parts duodenum, jejunum, and ileum. The small intestine is more than 20ft and is coiled in the abdomen. While food is in the small intestine more enzymes from the pancreas are released into the small intestines as well as bile from the liver to continue the break down process. Not only...
