If you’re talking anatomy and physiology, you’re talking about the human body and its organs. The 11 systems in the following list provide the means for every human activity from breathing to eating to moving to reproducing:

• Skeletal: Bones and connective tissues

• Muscular: Striated skeletal muscle

• Integumentary: Skin, nails, hair, glands in skin, nerve endings, and receptors in skin

• Nervous: Brain, spinal cord, ganglia, nerves, sensory organs

• Circulatory: Heart, blood vessels, blood

• Lymphatic: Tonsils, spleen, thymus, lymph nodes, lymphatic vessels, and lymph fluid

• Digestive: Mouth, esophagus, stomach, small and large intestine (all in gastrointestinal tract); accessory (or associated) organs include salivary glands, pancreas, liver, and gallbladder

• Respiratory: Nose, pharynx, larynx, trachea, bronchi, and lungs

• Urinary: Kidneys, ureters, bladder, and urethra

• Endocrine: Pituitary, thyroid, parathyroid, adrenals glands, endocrine portion of pancreas, ovaries, and testes (all secrete hormones into blood)

• Reproductive: Ovaries, uterine tubes, uterus, vagina, and vulva in females; testes, seminal vesicles, penis, urethra, prostate, and bulbourethral glands in males
