Question

explain the process taking place by heart in our body...... ​

Answer 1

Answer:

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.

Answer 2

✔️✔️✔️️heart is divided into four chambers:-

➖right auricle

➖ right ventricle

➖left auricle

➖ left ventricle.

⭕️The walls of the chambers are made up of a special muscle which contracts continuously and rhythmically to distribute blood to all the body cells.

✔️✔️✔️Working of heart

⭕️The heart has superior and inferior vena cava which carry deoxygenated blood from the upper and lower regions of the body and supply the deoxygenated blood to the right auricle of the heart.

⭕️The right ventricle contracts and passes the deoxygenated blood into the two pulmonary arteries, which pumps it to the lungs where the blood is oxygenated.

⭕️From the lungs, the pulmonary veins transport the oxygenated blood to the left atrium of the heart.

⭕️The blood passes to aorta from the left ventricle.

⭕️The left atrium contracts and the oxygenated blood enters the left ventricle.

⭕️ The aorta gives rise to many arteries that distribute the oxygenated blood to all the regions of the body.

⭕️here since the blood goes twice through the heart, it is known as "double circulation".
