ESSAYS:

Explain why blood flow in an insect can be much less vigorous than blood flow in a mammal. include a description of the insect circulatory system in your answer.

Back 49

The insect circulatory system consists of the hear, aorta, and blood. Blood flows into the heart through small openings called ostia. The ostia has valves that let blood to enter the heart but prevents it from escaping. Contractions of the heart pump the blood to the head through the aorta, which is the insect's only blood vessel. The blood travels back to the heart by flowing through the body cavity, supplying nutrients and removing wastes as it bathes the organs.
A mammal's blood must flow vigorously to provide oxygen; otherwise, the cells would quickly die from lack of oxygen. In contrast, an insect's blood does not supply oxygen to the cells. Since the cells do not depend on the blood for oxygen, the blood can flow much less vigorously and still keep the cells supplied with needed nutrients.
