Leaf Insects

Dear Friend Steemian....!!!!

Science - The main difference between them and humans who are vertebrates is the red blood cells. Humans and other vertebrate animals that have red blood cells and other invertebrates have hemolymph, a heterogeneous fluid that moistens all the internal tissues of their bodies. Hemolymph is given in the body coming from the heart that keeps pumping. Hemolymph is mostly air containing ions, carbohydrates, lipids, glycerol, amino acids, hormones, pigments, even some cells. The pigments in this hemolymph that give color to the insects, appear yellow or green.

Unlike the circulatory system in vertebrates, insects have an open circulatory system that does not require arteries and veins. Thus, Hemolymph flows freely throughout their bodies, lubricates the entire body tissues and transports nutrients and removes impurities. Respiratory system also Became a differentiator, IF OVERSEVENTS Oxygen Brought Blood Towards Whole Body while insect has How to breathe through a tracheal tube That sends Air to the whole Body WITH OTHER WAY.
