Question 1

connective tissue

Answer 1

provides structure and support, regulates communication

Question 2

extracellular matrix

Answer 2

made of polysaccharides and protein fibers,

Question 3

fibroblast

Answer 3

help to make the proteins collagen and elastin

Question 4

loose connective tissue

Answer 4

insulates, cushions, lubricates other tissue

Question 5

dense connective tissue

Answer 5

connects bone to muscle

Question 6

epithelial tissue

Answer 6

covers body and provides protection, imports, exports, has secretion glands

Question 7

muscle tissue

Answer 7

enables movement, made up of elongated cells that can contract (skeletal most, both; cardiac heart, unconscious; smooth contractions, unconscious)

Question 8

nervous tissue

Answer 8

responsible for communication; responds to stimuli (neurons transmit/receive signals; glial cells provide neurons w nutrients)

Question 9

organs

Answer 9

structures performing specific function; made of various tissue

Question 10

organ system

Answer 10

group of organs working together to perform specific function(s)

Question 11

homeostasis

Answer 11

maintaining consistent internal temperature

Question 12

set point

Answer 12

target value or range that a system corrects to

Question 13

negative feedback

Answer 13

return the system back to the set point

Question 14

positive feedback

Answer 14

allows for further deviation from point

Question 15

feedforward feedback

Answer 15

allows for change in set point

Question 16

thermoregulation

Answer 16

the modification of behavior or physiology to maintain a certain body temperature range

Question 17

osmoregulation

Answer 17

regulation of water balance by controlling dissolved solutes that influence osmosis

Question 18

malpighian tubes

Answer 18

tubules in insects that transport and reabsorb solutes, and then excrete waste

Question 19

kidneys

Answer 19

helps remove solutes and waste from blood, while regulating water balance
