300
Describe the flow of blood through the heart, include the oxygen status at each location.
- Oxygen poor blood is returned to the right atrium through the superior and inferior vena cava.
- Oxygen poor blood passes through the tricuspid atrioventricular valve into the right ventricle
- Oxygen poor blood passes through the pulmonary semilunar valve into the pulmonary truk
- Oxygen poor blood is carried from the pulmonary trunk to the pulmonary arteries to the lungs where the blood becomes oxygenated
- Oxygen rich blood is returned to the left atrium through the pulmonary veins
- Oxygen rich blood passes through the bicuspid atrioventricular valve into the left ventricle.
- Oxygen rich blood is forced out of the ventricle through the aortic semilunar valve into the aorta
- The blood is systemically circulated
