The human body is composed of interactive systems. There are specific functions for each of the organs in the systems, but they cannot operate by themselves.
Respiratory System - uses lungs, nasal passages, bronchi, pharynx, trachea, diaphragm, bronchial tubes - for intake of oxygen and removal of carbon dioxide from body.
Nervous System - depends on spinal cord, brain, nerves, skin, eyes, ears, tongue, nose - to control of body activities and the reaction to stimuli.
Digestive System - includes stomach, liver, teeth, tongue, pancreas, intestine, esophagus - for break down of food and absorption for use as energy.
Excretory System - comprises of kidneys, bladder, ureters,large intestine, skin - controls water and salt balance,The excretory system is responsible for removing wastes produced by the body. These wastes must be removed, or excreted, in order for the body to remain healthy. The human excretory system includes the skin, the kidneys, the large intestines and the liver. Each of these organs helps the body to excrete or eliminate waste that the body takes in when it eats or drinks something, or that the body produces during metabolic or life functions.
Endocrine System - includes pituitary gland, adrenal gland, thyroid gland, gonads - responsible for production of hormones and body regulation.
Skeletal and muscular System - includes bones, muscles - responsible for protection and movement.
Circulatory System - comprises of blood, blood vessels, heart, lymph - involves in transport of nutrients, metabolic wastes, water, salts, and disease fighting cells(WBCs).
Integumentary System - skin - protection of body from injury and bacteria, maintenance of tissue moisture, holds receptors for stimuli response, body heat regulation.
Immune System -(includes many types of protein, cells, organs, tissues)- Lymphocytes - T cells and B cells,Phagocytes,granulocytes,macrophages,dendritic cells.
Reproductive System - The major organs of the reproductive system includes, the external genitalia (penis and vulva) as well as a number of internal organs including the gamete producing gonads (testicles and ovaries).
