Entering the Heart: Erythrocytes (RBCs)

begin their journey returning from the body through the superior vena cava (from the upper body) or inferior vena cava (from the lower body), which are large veins that carry deoxygenated blood into the heart. The blood enters the right atrium of the heart.

2. Right Atrium to Right Ventricle: From the right atrium, the RBCs pass through the tricuspid valve (a one-way valve) into the right ventricle.

3. Right Ventricle to Pulmonary Circulation:

When the right ventricle contracts, the RBCs are pushed through the pulmonary valve into the pulmonary trunk. The pulmonary trunk splits into the right and left pulmonary arteries, which carry deoxygenated blood to the lungs. The RBC travels through these arteries to...
