Bodys Organ System And Its Functions Flashcards
(12 cards)
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.
Ex: Skin, Hair and nails
Integumentary system
Protects and supports body organs, and provides a framework the muscles use to cause movement. Blood cells are formed within bones. Bones store minerals.
Ex: Joint and bones
Skeletal system
Allows manipulation of the environment, locomotion, and facial expression. Maintains posture, and produces heat
ex: skeletal muscles
Muscular system
As the fast-acting control system of the body, it responds to internal and external changes by activating appropriate muscles and glands
Ex: brain, spinal cord, nerves
Nervous system
Glands secrete hormones that regulate processes such as growth, reproduction, and nutrient use (metabolism) by body cells
Ex: pineal gland, pituitary gland, thyroid gland, thymus, adrenal gland, ovary, testis
Endocrine system
Blood vessels transport blood, which carries oxygen, carbon dioxide, nutrients, wastes, etc. The heart pumps blood
Ex: heart and blood vessels
Cardiovascular system
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 in immunity. The immune response mounts the attack against foreign substances within the body.
Ex: red bone marrow, thymus, lymphatic vessels, thoracic duct, spleen, lymph nodes.
Lymphatic system/immunity
Keeps blood constantly supplied with oxygen and removes carbon dioxide. These exchanges occur through the walls of the air sacs of the lungs .
Ex: nasal cavity, pharynx, trachea, bronchus, lung
Respiratory system
Breaks down food into absorbable units that enter the blood for distribution to body cells. Indigestible foodstuffs are eliminated as feces
Ex: oral cavity, esophagus, liver, stomach, small intestine, large intestine, rectum, and anus
Digestive system
Eliminates nitrogenous wastes from the body. Regulates water, electrolyte, and acid-base balance of the blood.
Ex: kidney, ureter, urinary bladder, urethra
Urinary system
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.
Ex: prostate, penis, testis, scrotum, ductus deferens
Male reproductive system
Overall function is production of offspring. 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.
Ex: mammary glands (in breasts), ovary, uterine tube, uterus, vagina
Female reproductive system
