Introduction
The mammalian body contains many complex and interconnected systems. Each body system contributes a unique role to keep the mammalian body active and functional. However each body system relies on other body systems to perform their specific roles effectively.
Muscular System
The muscular system is responsible for the movement of the human body. There are more than 600 skeletal muscles within the body and this makes up 40% of a person’s body weight (Healthline, 2015). Muscle contractions within the skeletal system are produced when signals are sent from the nervous system to contract small or large muscle groups. These movements seem involuntary because we don’t need to concentrate to contract specific muscle groups. (Healthline, …show more content…
The organs that are involved in the digestive system include the mouth, oesophagus, stomach, small intestine, pancreas and liver (Fig 3). As food enters the mouth, the food is broken down by the method of chewing. Once the food is broken down it is swallowed and moves down the oesophagus at a slow pace. Afterwards the broken-down food enters the stomach where it is broken down even more by stomach acids. The upper muscle in the stomach relaxes to let food enter and lower muscle mixes the food with digestive juices. The food then enters the small intestine where it is to be broken down even further. It moves by the process of peristalsis whereby involuntary constriction and relaxation of the small intestine occurs. Proteins and carbohydrates and starches broken down and absorbed by the bloodstream. The pancreas is responsible for the control of blood sugar levels, which it does this by releasing the hormone ‘insulin’. The liver creates a digestive juice called bile. The bile acid is used to dissolve into the watery contents of the intestine (NIDDKD, …show more content…
“It absorbs fats and fat-soluble vitamins from the digestive system and delivers these nutrients to the cells that only require fats” (LymphNotes.com, 2012). The organs that are involved in the lymphatic system are the lymph nodes, tonsils, thymus and spleen. The lymphatic system manufactures proteins called antibodies. These antibodies are responsible for the producing a reaction when an invasion of a foreign substance, the antibody formation begins when an antigen stimulates specialized lymphocytes (form of a white blood cell) into action. These antibodies are harmless to the human body but they cover the foreign organism so the body can destroy them more easily (How Stuff Works,
