In this casing of frame, channel is pumped by a midsection finished vessels, and does not normally fill dust cavities. Hemoglobin causes craniate stock to turn red in the presence of collection O; but more importantly hemoglobin molecules in blood cells transport oxygen. The human closed circulatory system is sometimes called the cardiovascular system. This closed system is what helps humans existent on land.

Contraction of the ventricle forces blood from the heart through an artery. The heart muscle is composed of cardiac muscle cells.

The circulatory system functions in the rake of oxygen, nutrient molecules , and hormones and the removal of carbon dio! xide, ammonium hydroxide and former(a) metabolic wastes. Capillaries are the points of exchange between the blood and environ tissues. Materials cross in and out of the capillaries by button through or between the cells that line the capillary. Hemoglobin molecules in blood cells transport oxygen. Circulation of the blood moves blood to a localise or sites where it can be oxygenated, and...
