Digestive
Major Function:

Ingest, digest, and absorb food; remove solid waste; produce enzymes; break down and remove toxins.
Circulatory
Major Structure:

Heart, blood vessels (arteries, veins, capillaries), and blood cells (red blood cells, white blood cells, platelets)
Circulatory
Major Functions:

Circulate oxygen and immune cells to entire body, remove carbon dioxide, regulate body temperature.
Immune
Major Structure:

White blood cells, thymus, spleen, lymph nodes, and lymph vessels
Immune
Major Function:

Protect body from disease, return fluids from body tissues to circulatory system.
Respiratory
Major Structure:

Nose (nasal cavity), pharynx, larynx, trachea, bronchioles, bronchi, and lungs (with alveoli)
Respiratory
Major Function:

Inhale oxygen and exhale carbon dioxide; move them to and from all body cells by diffusion.

Major Function:

Cover internal and external body surfaces; trap and remove disease organisms; protect body and regulate body temperature.
Integumentary
Major Structure:

Serous, mucous, synovial, and cutaneous (skin) membranes
Nervous
Major Structure:

Nervous
Major Function:

Communicate information to and from body and environment; control all body functions. Responses are rapid.
Endocrine
Major Structure:

Glands: pituitary, thyroid, thymus, parathyroids, part of pancreas, adrenals, ovaries, and testes
Endocrine
Major Function:

Communicate and control via slow (chemical) responses; secrete hormones that control growth, metabolism, reproduction, and development.
Muscular
Major Structure:

Skeletal, smooth, and cardiac muscle groups
Muscular
Major Function:

Enables movement - voluntary, involuntary (such as breathing), and cardiac (heartbeat, blood flow).
Skeletal
Major Structure:

Bones of skeleton, joints, cartilage, and ligaments
Skeletal
Major Function:

Provide body structure and support work with muscles in movement; make blood cells; protect organs, store and release calcium and phosphorus.
Reproductive
Major Structure:

Testes, scrotum, seminal vesicles, vas deferens, urethra, and penis
Reproductive
Major Function:

Produce sperm for reproduction; produce testosterone for male sexual development
Reproductive
Major Structure:

Ovaries, oviducts, uterus, cervix, and vagina
Reproductive
Major Function:

Produce eggs; produce estrogen to control menstrual cycle and female sexual development.
Excretory
Major Structure:

Kidneys, ureters, bladder, and urethra
Excretory
Major Functions:

Maintain homeostasis of water and salts in body by removal or reabsorption; remove urea (a toxin).
