The body parts are grouped into several systems, including the nervous system of the brain, spinal cord and nerves that control the body, its muscles and glands; and the skeletal system of the bones and joints that support body structure, create blood cells and store minerals. Other systems include the cardiovascular, respiratory, digestive and reproductive systems.Continue Reading
The cardiovascular system consists of the heart that pumps the blood and the veins, arteries and capillaries through which the blood flows. The respiratory system, which provides oxygen to the blood and removes carbon dioxide, includes the lungs, trachea, larynx and nasal cavity. The digestive system includes the mouth, esophagus, stomach, liver and intestines, in addition to the rectum and anus. The body absorbs food and nutrients from the digestive system, which also excretes waste.
The reproductive system in men consists of the penis, testicles, scrotum, vas deferens and prostate gland. In women, it consists of the vagina, uterus, ovaries and breasts. The reproductive system's main purpose is to produce children.
The integumentary system, which consists of the nails, skin and hair, provides a protective layer. The system includes oil and sweat glands and receptors in the skin.
The lymphatic system of red bone marrow, lymphatic vessels, lymph nodes, thymus and thoracic duct helps regulate immunity by housing white blood cells. It also recycles fluids that leak from blood vessels back into the blood.Learn more about Human Anatomy
