The Eleven Organ Systems: Components, and Functions (MURDERS LINC)
Terms in this set (11)
Forms the external body covering, and protects deeper tissues from injury. Synthesizes vitamin D, and houses cutaneous (pain, pressure, etc.) receptors and sweat and oil glands.
Components: Hair, skin, and nails
Projects and supports body organs, and provides a framework the muscles use to cause movement.Blood cells are formed within bone. Bones store minerals.
Components: Bones, and Joints
Function: Protection of organs and levers for motion
Allows manipulation of the environment, locomotion, and facial expression. Maintains posture, and produces heat.
Components: Muscles and tendons
Function: Produces heat and allows manipulation of environment
As the fast-acting control system of the body, it responds to internal and external changes by activating appropriate muscles and glands.
Components: Brain, nerves, spinal cord
Glands secrete hormones that regulate processes such as growth, reproduction and nutrient use (metabolism) by body cells.
Components: Hormone glands (thyroid gland, thymus, adrenal gland, pancreas, pineal gland, pituitary gland, ovaries, testis.)
Function: Reproduction and growth processes
Blood vessels transport blood, which carries oxygen, carbon dioxide, nutrients, waste, etc. The heart pumps blood.
Components: Heart, Blood Vessels
Function: Pumping Blood
Picks up fluid leaked from blood vessels and returns it to blood. Disposes of debris in the lymphatic stream. Houses white blood cells (lymphocytes) involved with immunity. The immune response mounts the attack against foreign substances within the body.
Components: Red bone marrow, Thymus, lymphatic vessels, thoracic duct, spleen, lymph nodes.
Functions: Works with immune system, disposes of debris. Cleans blood/tissue
Keeps blood constantly supplied with oxygen and removes carbon dioxide. The gaseous exchanges occur the walls of the air sacs in the lungs.
Components: Nasal cavity, pharynx, larynx, trachea, lung, and bronchus.
Function: Keeps blood supplied with oxygen
Breaks down food into absorbable units that enter the blood for distribution to body cells. indigestible food stuffs are eliminated as feces.
Components: Oral Cavity, Esophagus, Liver, stomach, small intestine, large intestine, rectum, anus.
Function: Eliminates Waste
Eliminates nitrogenous wastes from the body. Regulates water, electrolyte, and acid-base balance in the blood.
Components: Kidney, ureter, urinary bladder, urethra
Function: Regulates water/electrolytes, eliminates waste
Overall function is production of offspring. Testes produce sperm and male sex hormone, and male ducts and glands aid in delivery of sperm to the female reproductive tract. Ovaries produce eggs and female sex hormones. The remaining female structures serve as sites for fertilization and development of the fetus. Mammary glands of female breasts produce milk to nourish the newborn.
Components: (Male) Prostate, penis, testis, ductus deferens, and scrotum. (Female) Mammary glands, ovary, uterus, uterine tube, vagina.
