Question

Describe the functions of the heart.

Answer 1

• The heart is a mesodermally derived organ situated in the thoracic cavity between the two lungs, slightly tilted to the left.
• It has the size of a clenched fist.

FUNCTIONS OF THE HEART:-

• First, it receives deoxygenated blood carrying metabolic waste products from the body and pumps it to the lungs for oxygenation.
  
• To pump oxygenated blood to the other body parts.
• To maintain blood pressure.
  
• To pump hormones and nutrients to different parts of the body.

The heart functions in the following ways:-

• The right auricle receives deoxygenated blood with carbon dioxide($C{O}_2$) from all parts of the body.
• The collected blood is then transported to the lungs for purification.
• In the lungs, the exchange of gases takes place and oxygenated blood is sent back to the left auricle which pumps it to the left ventricle.
• The left ventricle pumps off the purified blood to all parts of the body through arteries.
