ANATOMY

Detailed explanation-1: -Oxygen-deficient, carbon dioxide-rich blood returns to the right side of the heart through two large veins, the superior vena cava and the inferior vena cava. Then the blood is pumped through the pulmonary artery to the lungs, where it picks up oxygen and releases carbon dioxide.

Detailed explanation-2: -In the human heart, oxygenated blood flows through the right side and carbon dioxide rich blood flows through the left side.

Detailed explanation-3: -The right side of the heart The right upper chamber (atrium) takes in deoxygenated blood that is loaded with carbon dioxide.

Detailed explanation-4: -The right side of the heart pumps oxygen-poor blood from the body to the lungs, where it receives oxygen. The left side of the heart pumps oxygen-rich blood from the lungs to the body. Once the body’s organs and tissues have removed the oxygen from the blood, the blood returns to the heart. The cycle is then repeated.

Detailed explanation-5: -Therefore, the left side of the heart contains oxygenated blood.
