Gas Journey Through the Body

Gas Journey Through the Body, Gas circulates throughout the body via the bloodstream which also carries the red blood cells. Red blood cells contain hemoglobin, a protein composed of four chains of amino acids. Are each associated with different heme group, with an iron atom that is able to bind a molecule O2.

Gas Journey Through the Body, This bond is a reversible reaction (back and forth), so that the heme group can be separated again from the oxygen.Minor circulation of blood flowing into the right lung and entered the pulmonary artery flow to left lung in vulmonal vein, the heart circulates blood through the pulmonary artery to the lungs pick up oxygen. Red blood cells circulate oxygen duty. Shaped like a disc with two convex surfaces and in it there is hemoglobin.

The circulation of oxygen and carbon dioxide in the creature is as follows: CO2 released into the bloodstream cells, particularly into the vein through the arteries pulomonal. Gas exchange occurs in the alveoli. CO2 is released into the alveoli and of alveolar O2 is released into the pulmonary capillaries, and then bound by the hemoglobin of red blood cells. Oxygenated blood from the lungs by the pulmonary venous received and sent back to the heart. Arriving at the heart, blood is pumped into the aorta and dilairkan to all body tissues to deliver oxygen contained in hemoglobin.
