Answer 1

The correct option is A flow of oxygenated blood from left ventricle to all parts of the body and the return of deoxygenated blood from various body parts to the right atrium

Flow of oxygenated blood from left ventricle to all parts of the body and the return of deoxygenated blood from various body parts to the right atrium is called systemic circulation.
Flow of oxygenated blood from the ascending aorta to the heart muscle and the return of deoxygenated blood from the heart muscle to the right atrium is called coronary circulation.
Flow of deoxygenated blood from the right ventricle to the lungs and the return of oxygenated blood from the lungs to the left atrium is called pulmonary circulation.
Flow of deoxygenated blood from the digestive organs to the liver before returning to the heart is carried out by hepatic portal system.
