Intergumentary System

Organisms are composed of atoms that form molecules and form macromolecules (Shier, Butler, & Lewis, 2009). These molecules combine to form organelles, which constitute tissue cells (page 3). Tissues form organs and organs together to form an organ system (p3). These organ systems constitute organisms (p3). All organ systems have important functions in the body. These systems work together to maintain and support the necessary conditions for proper functioning of cells, tissues, and organs.

Organ systems (also called systems) are a series of organs that perform specific tasks collectively. In humans and other animals, the organ system is the hull, the lymphatic system, the muscular system, the nervous system, the reproductive system, the urinary tract system, the respiratory system, the skeletal system and the immune system. In humans, the digestive system consists essentially of the gastrointestinal tract. In particular, the gastrointestinal tract consists of organs, pharynx, esophagus, stomach, small intestine, large intestine and rectum organs. It also includes auxiliary digestive glands such as salivary glands, liver, gall bladder and pancreas. These organs and glands work together and digest the food into smaller components, which are absorptive forms absorbed by the body. Digestion and chewing (chewing) forms a bolus and helps to start digestion in the mouth

The organ system is a group of special organs working together to meet key physiological needs. For example, mouth, esophagus, stomach, small intestine, and colon are all gastrointestinal organs. The digestive system is an organ system responsible for breaking down food into nutrients that can be transported via blood.

The digestive system extending from the mouth to the anus receives the food, plays a role of digesting and discharging excrement. This system includes not only the stomach, small intestine and large intestine that moves and absorbs food, but also related organs that produce digestive enzymes, remove toxins, and store substances necessary for digestion such as pancreas, liver, gall bladder I will. Organ systems often work together to achieve complex tasks. For example, after a large meal, several organ systems work together to help the digestive system get more blood to perform its function. The digestive system helps the cardiovascular system and the nervous system. Gastrointestinal vessels dilate to deliver more blood. Nerve impulses are sent to the brain to inform of increased digestive activity
