Organ Systems Flashcards
Forms the external body and protects deeper tissue from injury
- synthesizes vitamin D and houses cutaneous (pain, pressure, etc) receptors, and sweat and oil glands
> includes - hair, skin, nails, etc
Integumentary System
Protects and supports body organs, and provides a framework the muscles use to cause movement
- blood cells are formed with bones
- bones store minerals
> includes - bones and joints
Skeletal System
Allows manipulation of the environment, locomotion, and facial expression
- maintains posture and produces heat
> includes - skeletal muscles
Muscular System
As the fast-acting control system of the body, it responds to internal and external changes by activating the appropriate muscles and glands
> includes - brain, nerves, and spinal cord
Nervous System
Glands secrete hormones that regulate processes like growth, reproduction, and nutrient use (meabolism) by body cells
> includes - pineal gland, pituitary gland, thyroid gland, adrenial gland, pancreas, testies, and ovaries
Endocrine System
Blood vessels transport blood which carries oxygen, carbon dioxide, nutrients, waste, etc
- heart pumps blood throughout body
> includes - heart and blood vessels
Cardiovascular System
Picks up fluid leaked from blood vessels and returns it to the blood, disposes of debris in the system
- houses white blood cells (lymphocytes) involved in immunity
> includes - red bone marrow, thymus, lymphatic vessels, thyracic duct, spleen, and lymph nodes
Lymphatic or Immunity System
Keeps blood constantly supplied with oxygen and removes carbon dioxide
- these exchanges occur through the walls of the air sacs of the lungs
> includes - nasal cavity, pharynx, larynxs, trachea, bronchus, and lungs
Resperatory System
Breaks down food into absorbable units that enter the body for distribution to the cells
- indigestible foods are eliminated as feces
> includes - oral cavity, esophagus, liver, stomach, intestines, rectum, and anus
Digestive System
Eliminates nitrogeneous wastes from the body
- regulates water, electrolytes, and acid-based balance in blood
> includes - kidney, ureter, urinary bladder, and urethera
Urinary System
Overall function is the production of offspring
- testis produce sperm, male sex hormone, make ducts and glands aid in the delivery of sperm to the female reproductive tract
> includes - prostate, penis, testis, scrotum, ductus deferens
Male Reproductive System
Overall function is the production of offspring
- ovaries produce eggs and female sex hormones
- the remalning female structures serve as sites for fertelization and development of the fetus
- Mammary glands of female breasts produce nutrience to norish the newborn
> includes - mammary glands (in breasts), ovary, uterus, vagina, and uterine tube
Female Reproductive System
