(21) Animal Physiology Flashcards
(19 cards)
connective tissue
provides structure and support, regulates communication
extracellular matrix
made of polysaccharides and protein fibers,
fibroblast
help to make the proteins collagen and elastin
loose connective tissue
insulates, cushions, lubricates other tissue
dense connective tissue
connects bone to muscle
epithelial tissue
covers body and provides protection, imports, exports, has secretion glands
muscle tissue
enables movement, made up of elongated cells that can contract (skeletal most, both; cardiac heart, unconscious; smooth contractions, unconscious)
nervous tissue
responsible for communication; responds to stimuli (neurons transmit/receive signals; glial cells provide neurons w nutrients)
organs
structures performing specific function; made of various tissue
organ system
group of organs working together to perform specific function(s)
homeostasis
maintaining consistent internal temperature
set point
target value or range that a system corrects to
negative feedback
return the system back to the set point
positive feedback
allows for further deviation from point
feedforward feedback
allows for change in set point
thermoregulation
the modification of behavior or physiology to maintain a certain body temperature range
osmoregulation
regulation of water balance by controlling dissolved solutes that influence osmosis
malpighian tubes
tubules in insects that transport and reabsorb solutes, and then excrete waste
kidneys
helps remove solutes and waste from blood, while regulating water balance
