Detailed explanation-1: -The heart is a pump, usually beating about 60 to 100 times per minute. With each heartbeat, the heart sends blood throughout our bodies, carrying oxygen to every cell. After delivering the oxygen, the blood returns to the heart. The heart then sends the blood to the lungs to pick up more oxygen.
Detailed explanation-2: -There are two phases to your heart’s pumping cycle: systole-this is when your heart contracts, pushing blood out of the chambers. diastole-this is the period between contractions when the muscle of your heart (myocardium) relaxes and the chambers fill with blood.
Detailed explanation-3: -Your heart pumps blood around the body all the time-about 5 litres (8 pints) of it. This is called circulation. Your heart, blood and blood vessels together make up your cardiovascular system (or heart and circulatory system).
Detailed explanation-4: -The correct option is B False. Heart: The heart plays an eminent role in the circulatory system. It serves as a pumping organ and pumps blood to all parts of the body.
