Question

8. Complete the following scheme of circulation of a red blood cells in the human body. Right atrium through the_valve to the , through to the valve to the pulmonary trunk, to the arteries, to the capillary beds of the lungs, then exchange of lungs. After exchange, the O2 rich blood returns the left atrium through the to the left ventricle through the valve, to the systemic arteries, finally getting exchange O2 and CO2 in the tissues. After exchange, CO2 rich blood returns to the systemic veins, to the and and between the capillary and veins, valve, to the through the with entering the right atrium.

Explanation / Answer

Right atrium through the TRICUSPID VALVE to the RIGHT VENTRICLE, through to the SEMILUNAR OR PULMONIC VALVE to the pulmonary trunk, tothe PULMONARY ARTERIES, to the capillary bed of the lungs,then exchange of CARBON DIOXIDE AND OXYGEN between the capillary and lungs. After exhange, the O2 rich blood return the left atrium through the PULMONARY VEINS, to the left ventricle through BICUSPID VALVE, to the AORTA through the AORTIC VALVE, to the systemic arteries, finally getting exchange of O2 and CO2 in the BLOOD with tissues. After exchange, CO2 rich blood returns to the systemic vein, to the SUPERIOR VENA CAVA AND INFERIOR VENA CAVA entering the right atrium.
