Glucagon is the hormone that helps in restoring the levels of blood glucose levels. It is produced by alpha cells of the pancreas. It stimulates the liver to break the glycogen, so that they may be utilized by the body, as a source of energy. It also stimulates glucose synthesis in the body.
Answer:
The correct flow is - the body (a)<u> Venules/vein/vena cava</u> (b) <u>Right atrium</u> tricuspid valve (c) <u>Right ventricle</u> (d)<u> Pulmonary artery, </u>capillary bed of the lungs(alveoli)
Explanation:
Deoxygenated blood is moved from the tissues to the venules, veins or vena cava to the right atrium chamber and move through the tricuspid valve present in between both right chambers right atrium and right ventricle.
From the right ventricle, the deoxygenated blood is pumped into the pulmonary artery that takes the blood to the lungs more specifically to the capillary bed of lungs.
Thus, the flow is - the body (a)<u> Venules/vein/vena cava</u> (b) <u>Right atrium</u> tricuspid valve (c) <u>Right ventricle</u> (d)<u> Pulmonary artery, </u>capillary bed of the lungs(alveoli)
Answer:
