Blood glucose

Question 1

define homeostasis

Answer 1

maintenance of a constant internal environment for the life processes to occur

Question 2

what happens if you have high blood glucose - mention receptors and effectors

Answer 2

B cells in the islet of Langerhans in the pancreas will detect ( receptors) an increase in glucose in the blood. it will then secrete the hormone insulin into the blood which will absorb glucose from the blood to body cells and stimulate the conversion of glucose to glycogen in the liver and muscles (effectors). The B cells will detect decrease in glucose and inhibit insulin and glucose will be maintained to set point

Question 3

what happens if you have low blood glucose - mention receptors and effectors

Answer 3

A cell in the pancreas islet of Langerhans (receptors) will detect and secrete the hormone glucagon which will stimulate the conversion of glycogen to glucose in liver and muscle cells (effectors) which will then increase glucose in the blood. the increase will be detected by the A cells and they will inhibit further secretion of glucagon as glucose is at a set point

Question 4

which hormones are antagonistic

Answer 4

insulin and glucagon

Question 5

symptoms and types of diabetes mellitus
