endocrine: produce hormones and lack ducts

Question 12

two types of hormones

Answer 12

steroids and nonsteroids

Question 13

steroids

Question 14

nonsteroids

Answer 14

every other hormone

water soluble

bind to hormone receptors on the lipid bilayer of the cells that causes specific metabolic effects.

metabolic diseases such as diabetes, hyperthyroidism, and gigantism.

Question 17

diabetes

Answer 17

high blood sugar levels

Question 18

hyperthyroidism

Answer 18

malfunction of regulatory feedback loops leading to the overproduction of thyroid hormone (TH)

Question 19

gigantism and acromegaly

Answer 19
