Trace the movement of oxygenated blood in the body
Answers
Answer:
Stage 1: Pulmonary Circulation
The blood from all parts of the body, enter the heart through both the vena cava and pour into the right auricle. As the valves open, the blood flows into the right ventricle. Now, the blood travels to the lungs for purification or oxygenation of the blood through a special artery called the pulmonary artery.
After getting oxygenated, the oxygenated blood comes to the heart's left auricle through the pulmonary vein.
Stage 2: Systemic Circulation
After entering the heart through the pulmonary artery, the blood flows from the left auricle to the left ventricle. Later, this oxygenated blood is pumped out to all the parts of the body through the largest artery called Aorta. This is called systemic circulation.
Circulation of blood from heart to all parts is systemic circulation and circulation of blood from heart to lungs is called pulmonary circulation.

Answer:
Explanation:
Oxygenated blood moves from the lungs to the left atrium (upper chamber of the heart on the left). The atrium has a thin wall. The blood is collected in the left atrium when the left atrium relaxes. As soon as the left atrium contracts, the left ventricle expands and blood is transferred to the left ventricle.
