$\sf\bullet\orange{Working \ of \ the \ Heart}$

➝ The right atrium recieves the deoxygenated blood and travels through the tricuspid valve to the right ventricle.

➝ Blood from the right ventricle flows through the pulmonary artery and reaches the lungs from where the oxygen present in the alveoli diffuses into the blood.

➝ Now the oxygenated blood comes back to the Left Atrium of the heart.

➝ Then this blood moves into the left ventricle through the bicuspid valve.

➝ And finally the oxygen is pumped via the akota to the cells of our body and this process goes on.

Answer 2

The heart is roughly cone shaped hollow organ. It is approximately the size of owner’s closed fist and weighs about 250-300 gm in female and 300-350gm in the male. The heart lies in the thoracic cavity in the space between the lungs (mediastinum) anterior to the vertebral column and posterior to the sternum. The heart consists of 4 chambers. At first, the heart is divided into the right and left side by the septum. Each side is further divided into 2 chambers each by the atrioventricular valve. The upper two chambers are called atrium and lower two are called ventricles. Atrium are thin-walled chamber separated by an interauricular septum

The right atrium receives impure blood from the body through the opening via superior and inferior vena cava. Ventricles are a thick-walled chamber. separated by the thick inter-ventricular septum.
