The hormones glucagon and insulin are produced by the pancreas and regulate the amount of glucose in the blood. Glucagon stimulates liver cells to release glucose into the blood, whereas insulin stimulates body cells to absorb glucose from the blood. a. Which system is described above?

b. Explain in detail how the description above relates to homeostasis?

the oxygenated blood then leaves the lungs through pulmonary veins, which return it to the left heart, completing the pulmonary cycle. this blood then enters the left atrium, which pumps it through the mitral valve into the left ventricle. from the left ventricle, the blood passes through the aortic valve to the aorta.

deoxygenated blood leaves through the right ventricle through the pulmonary artery. from the right atrium, the blood is pumped through the tricuspid valve (or right atrioventricular valve), into the right ventricle.
