Document Summary
Synthesis and breakdown of glycogen is also important in glucose homeostasis. If blood glucose above normal; insulin secretion triggers body cells to uptake glucose: only brain cells do not respond to insulin; will uptake glucose with or without insulin iii. Figure 40. 21 glucose regulation cycle: diabetes mellitus; disorder caused by deficiency of, or decreased response to insulin. Other organisms evolved circulatory system to move fluid between cells/tissues and where exchange of materials occurs: there are 3 basic components of a circulatory system, circulatory fluid (special type of fluid used to help move materials) ii. Mammalian heart contracts and relaxes in rhythmic cycles driving circulation: beginning with pulmonary circuit, heart pumps blood in following sequence. Figure 42. 5***: right-ventricle contracts and pumps blood to lungs via pulmonary arteries. Figure 42. 7 heart circulation: volume of blood pumped by each ventricle = cardiac output a.
