Nervous system- (brain, sensory receptor, spinal cord, nerves) Control system of the body and responds to internal and external changes by activating muscles and glands

Endocrine System- (pineal gland, pituitary gland, thyroid gland, thymus, adrenal gland, pancreas, ovary, testis) glands secrete hormones that regulate things like growth, reproduction and metabolism

Cardiovascular System- (heart, blood vessels) blood vessels transport blood (carries oxygen, carbon dioxide, nutrients wastes etc.) heart pumps blood.

Lymphatic System/Immunity- (red bone marrow, thymus, lymphatic vessels, thoratic duct, spleen, lymph nodes) picks up fluid leaked from blood vessels, disposes of debris in the lymphatic stream and houses white blood cells.

Respiratory System- (nasal cavity, pharynx, larynx, trachea, lung, bronchus) keeps blood supplied with oxygen and rids it of Carbon Dioxide.

Digestive System- (oral cavity, esophagus, large intestine, liver, stomach, small intestine, rectum and anus) breaks down food into absorbable units to enter the blood and indigestible foodstuffs exit as feces.

Urinary System- (kidney, ureter, urinary bladder, urethra) eliminates nitrogenous wastes, regulates water, electrolyte and pH balance of blood.

Make Reproductive System- (prostate gland, penis, testis, scrotum, ductus deferen) production of offspring; delivery if sperm to the female reproductive tract.
