To determine:
The difference between hemolymph and the blood.
Introduction:
A fluid that is almost equivalent to the blood that is present in majority of the invertebrate animals is known as hemolymph. This fluid occupies the haemocoel. In other words, it is the circulating blood of the insects. Hemolymph movement occurs through the open circulatory system.
Explanation of Solution
Hemolymph is fundamentally an interstitial fluid that enters into the body tissues. It is pumped through the open-ended circulatory system. Vertebrate blood refers to the circulatory fluid that remains inside the vessels. The blood is pumped through a closed circulatory system and exchanges materials with the cells of the body through the interstitial fluid.
Erythrocytes are present in the blood, whereas it is absent in the hemolymph. High concentrations of amino acid are present in the blood, which is absent in the hemolymph. Major components of the blood are the red blood cells and plasma, whereas the major part of the hemolymph is formed of water.
