Blood circulates throughout the body to transport oxygen and nutrients to cells, and to carry waste products to the kidneys where waste is removed by filtration.
Lymphatic System
- Lymph, lymphatic vessels, and lymph nodes
Removes and transports waste products from the fluid between the cells. Destroys harmful substances such as pathogens and cancer cells in the lymph nodes. Returns the filtered lymph to the bloodstream where it becomes plasma again.
Immune System

Nervous System
- Nerves, brain, and spinal cord
Coordinates the reception of stimuli. Transmits messages throughout the body.
Special Senses
- Eyes and ears
Receive visual and auditory information and transmit it to the brain.
Integumentary System
- Skin, sebaceous glands, and sweat glands
Protects the body against invasion by bacteria. Aids in regulating the body temperature and water content.
Endocrine System
- Adrenal glands, gonads, pancreas, parathyroids, pineal, pituitary, thymus, and thyroid
integrates all body functions
Reproductive Systems
- Male: penis and testicles; Female: ovaries, uterus, and vagina
