Question

a feedback mechanism in the human body is shown. insulin from the pancreas allows the liver to convert excess glucose into glycogen. blood glucose level rises above normal. normal blood glucose level. blood glucose levels fall. blood glucose levels rise. glucagon from the pancreas allows the liver to convert glycogen into glucose. based on this diagram, which two systems interact to maintain homeostasis? a the circulatory and endocrine system work together to keep blood sugar constant b the nervous and excretory systems work together to convert glycogen into glucose c the immune and circulatory systems work together to circulate blood through the pancreas d the nervous and reproductive system work together to produce insulin

Explanation:

The pancreas, an endocrine - gland, secretes insulin and glucagon to regulate blood glucose levels. These hormones travel through the bloodstream (circulatory system) to the liver. The interaction is between the endocrine system (pancreas) and circulatory system to maintain blood - sugar homeostasis.

Answer:

a. The circulatory and endocrine system work together to keep blood sugar constant
