Systems of the body Flashcards
Integumentary system
SKIN. Forms the external body covering. Protects deeper tissue from injury. Synthesizes vitamin D. Location of cutaneous (pain, pressure, temperature) receptors. And sweat and oil glands.
Skeletal system
CARTILAGES, JOINTS, BONES. Protects and supports body organs. Provides a framework the muscles use to cause movement. Blood cells are formed within bones. Stores minerals.
Muscular system
SKELETAL MUSCLES. Allows manipulation of the environment, locomotion, an facial expressions. Maintains posture and produces heat.
Nervous System
BRAIN, SENSORY RECEPTORS, SPUNAL CORD, NERVES. Fast acting control system of the body. Responds to internal and external changes by activating appropriate muscles and glands
Endocrine system
PINEAL GLAND, PITUITARY GLAND, THYROID GLAND, THYMUS GLANS, ADRENAL GLAND, PANCREAS, TESTES, OVARY. Gland secrete hormones that regulate processes such as growth, reproduction, and nutrient use (metabolism) by body cells
Cardiovascular system
HEART, BLOOD VESSELS. blood vessels transport blood which carries oxygen, carbon dioxide, nutrients, waste, etc. heart pumps blood.
Lymphatic system
THORACIC DUCT, LYMPH NODES, LYMPHATIC VESSELS. the network of vessels through which lymph drains from the tissues into the blood.
Respiratory system
NASAL CAV, PHARYNX, LARYNX, TRACHEA, BRONCHUS, LEFT LUNG. keeps blood constantly supplied with oxygen and removes carbon dioxide. The gaseous exchanges occur through the walls of the air sacs of the lungs.
Digestive system
ORAL CAV. ESOPHAGUS, STOMACH, SMALL INTESTINE, LARGE INTESTINE, RECTUM, ANUS. Breaks down food into absorbable units that enter the blood for distribution to body cells. Indigestible food stuffs are eliminated as feces.
Urinary system
KIDNEY, URETER, URINARY BLADDER, URETHRA. Eliminates nitrogenous waste from the body. Regulates water, electrolytes, and acid-base balance of the blood
male and female reproductive systems
Overall function of the reproductive system is production of offspring. Testes produce sperm and male sex hormones. Ducts and glands aid in delivery of viable sperm to the female reproductive tract. Ovaries produce eggs and female sex hormones. Remains structures serves as sites for fertilization and development of the fetus. Memory glands of female breast produce milk to nurse the newborn.
