Question

The correct pathway of blood circulation in the human body is

• A. Heart $\to$ Pulmonary vein $\to$ Capillary $\to$ Pulmonary artery $\to$ Heart
• B. Heart $\to$ Pulmonary artery $\to$ Lungs $\to$ Pulmonary vein $\to$ Body systems $\to$ Heart
• C. Heart $\to$ Pulmonary artery $\to$ Lungs $\to$ Pulmonary vein $\to$ Heart $\to$ Body systems
• D. Body systems $\to$ Lungs $\to$ Heart $\to$ Vein $\to$ Capillary $\to$ Artery.
• E. Heart $\to$ Pulmonary artery $\to$ Lungs $\to$ Body systems $\to$ Vein $\to$ Heart.

Answer 1

The correct option is C Heart $\to$ Pulmonary artery $\to$ Lungs $\to$ Pulmonary vein $\to$ Heart $\to$ Body systems

Blood enters the heart through two large veins, the inferior and superior vena cava, emptying oxygen-poor blood from the body into the right atrium. As the ventricle contracts, blood leaves the heart through the pulmonary valve, into the pulmonary artery and to the lungs, where it is oxygenated.

So, the correct option is 'Option C'.
