31 Οκτ 2024 · The right atrium receives venous blood from the head, chest, and arms via the large vein called the superior vena cava and receives blood from the abdomen, pelvic region, and legs via the inferior vena cava. Blood then passes through the tricuspid valve to the right ventricle, which propels it through the pulmonary artery to the lungs.
As shown in Figure 17.2.3 17.2. 3, the heart has four inner chambers: a right atrium and ventricle and a left atrium and ventricle. On each side of the heart, blood is pumped from the atrium to the ventricle below it and from the ventricle out of the heart.
Schematic cross sectional diagram of the heart. Key anatomical structures are labelled and the flow of electrical activity is illustrated by the white arrows.
