Organ Systems

Organ Systems:

Integumentary system – skin, glands, and hair; protects body

Skeletal system – bones, joints, ligaments; protects, supports body

organs, movement

Muscular system – skeletal muscles and tendons; movement

Nervous system – neuron cells (generate, conduct, and respond

to nerve impuses) and supporting cells (insulate, nourish, and

protect); fast-acting communication and control system

Endocrine system – various glands and tissue

scattered through out body; secrete hormones to

maintain homeostasis

Cardiovascular system – heart, blood vessels, and blood; transports oxygen,

nutrients, and waste

Lymphatic/immune system – lymphatic vessels and organs; defense to fight

infection

Respiratory system – larynx, trachea, bronchi, and lungs; supplies oxygen,

removes carbon dioxide

Digestive system – mouth, esophagus, stomach, and

intestine; breaks down food and absorbs nutrients

Urinary system – kidneys, bladder, ureter, and urethra;

eliminates wastes regulates water, electrolyte, and acid

base homeostasis

Reproductive systems – testes, ovaries, ducts, penis,

vagina, uterus; produce eggs and sperm and hormones;

in females supports and nourishes the embryo and fetus
