Protects the body, provides support and a framework for muscles to act upon, contains bone marrow for blood cells to develop in, and stores minerals such as calcium
Bones, Joint Cartilage
Llymph Fluid, Vessels, Nodes, Spleen, Nodules, and Thymus
Filters blood in order to extract metabolic waste and maintain the acid-base and mineral balance. It is also helps to regulate the production of red blood cells
Brain and Spinal Chord
Responsible for the breakdown of ingested food, both physically and chemically, so that nutrients can be absorbed. It is also involved in the absorption of water and removal of undigested food
Female: gonads (ovaries), uterine tubes, uterus, vagina, clitoris, labia, and mammary glands. Male: gonads (testes), epididymes, ductus deferens, penis, and scrotum
Oral cavity, Pharynx, Esophagus, Stomach, Intestines, Salivary glands, Liver, Gallbladder, and Pancreas
Hormones alter the metabolism of target cells. The hormone can be very specific, affecting only one cell type, or very general, affecting many cell types
Pumps blood around the body through the blood vessels to deliver oxygen and nutrients to cells and remove metabolic waste. Regulates the water content of body fluids, the acid-base balance, and the temperature of the body
Skin, Hair, and Nails
Detecting changes (sensory function) in the internal and external environment, encoding them into electrical impulses, and transmitting them to control a stimulus response.
Kidneys, Ureters, Urinary Bladder, and Urethra
Produce gametes (egg or sperm cells), and to transport and sustain these structures; also to nurture a developing fetus.
Pituitary, Thyroid, Pineal, Parathyroid, and Adrenal Glands
Skeletal, Cardiac, and Smooth
Responsible for transporting various substances; it takes lipids from the gastrointestinal tract to the blood, and transports protein and fluids back to the bloodstream. It is also responsible for the development of lymphocytes, the cells responsible for fighting disease
Enables the body to move by the action of opposing muscular contraction and relaxation. It also maintains posture and plays a role in thermoregulation
Blood, Heart, and Blood Vessels
Responsible for oxygen/carbon dioxide gas exchange with the blood and also involved in the regulation of acid-base balance and sound production
Pharynx, Larynx, Trachea, Bronchi, Bronchioles, and Lungs
Protects the body from the external environment, excretes metabolic waste, helps to make vitamin D, and detects pain, touch, dehydration, and changes in temperature
