Question

Circulatory Systems: We don’t know exactly how/if invertebrates, having open circulatory systems precisely control the delivery/removal hemolymph (blood) to specific tissues. A) Given your readings, and perhaps a foray into the peer reviewed literature, develop an explanation of how an insect with an open circulatory system can adequately supply the needs of say muscle during extremely intense activity. B) What are two tests you will perform to evaluate your explanation? What do you expect to find with each test?

Explanation / Answer

In open circulatory system,the heart pump.blood into body cavities which gets filled with blood and organs bath in this blood filled cavity.The blood return to heart by interstitium.

How the insect maintain needs of.muscle.is.explianed by the theory.

The muscle.which is involved require more.oxygen and produces CO2 more.This concentration gradient produced between the blood filled cavity and the.muscle is.high so exchange of gases is better here .

Ans..B...the test that we will perform.

Haemoglobin

Myoglobin

The insects with trachial system.in open circulation does not require these respiratory pigments to.transport gases.These are the pigments that provide color to our blood and muscles .this is the reason their blood is colorless.
