Body Systems

Brenda Young Several systems in the human body maintain its proper function. These systems compress disease and transmission maintain proper blood flow to lungs and body, and dispose of any hook that the body no longer needs. Learning how each system whole kit and boodle was educational and quite amazing. Our tolerant system fights off bacteria, viruses, and disease. Our environment if all-encompassing of harmful toxins that our bodies are subject to daily.Most of the viruses are harmless, and our immune system cornerstone protect against them. The few that are able to invade our bodys defenses can father terrible disease and possibly death. A virus by itself is incompetent of reproducing, it is not until the body and cells become invaded that disease can set in. In a short amount of time, the infected cells generate hundreds of thousands of new viruses released into the bloodstream where they are free to infect other cells.Skin, inflammatory response and the immune system are three defenses our body uses to fight disease and transmission (Chairs, Immune System, 2013). Without the digestive system, the protein ND starch in our food could not be broken down into usable molecules, and therefore would be useless. Digestion and assimilation of the food we eat is done so with the help of several organs in our body. The nervous system and the endocrine system control the digestion process.Once we create chewed our food and activated the release of saliva, the brain sends a message to our stay where a protein- digesting enzyme from glands in the stomachs lining is released. Two hormones then circulate in the blood entering the pancreas where pancreatic Juice containing food- setting enzymes and sodium bicarbonate is released and food is broken down for the body to use and absorb (Chairs, digestive System, 2013).The entire way the human body functions are interesting and unbelievable. By maintaining good health with nutrition and exercise, we help the immun e system fight infection and our digestive system can easily dispose of and luckiness down the food we eat. When our body is healthy, our minds are healthy. References Chairs, D. D. (2013). Human Body Systems Structure, Body, milieu (2nd De. ).
