Determine the path of blood in the pulmonary circulation.

Circulation in a small circle begins from the right ventricle of the heart. The blood is thrown out by it and begins its short path for oxygenation. This path takes approximately 6 seconds. After the right ventricle, the blood disappears into the pulmonary trunk, then into the lungs, veins and passes into the left atrium. The blood in the capillaries is saturated with oxygen and breaks the bonds from the accumulated carbon dioxide molecules. Erythrocytes are capable of this due to hemoglobin, which creates bonds with oxygen for further transport.
