Answer:
Heart, the mesodermally derived organ, is situated in the thoracic cavity, in between the two lungs, slightly tilted to the left. It has the size of a clenched fist.
FUNCTIONS OF THE HEART:
- The right auricle and right ventricle receive blood with carbon dioxide(CO 2 ) from all parts of the body.
- The collected blood is then pumped to the lungs for purification.
- In the lungs, the exchange of gases takes place and purified blood is sent back to the left auricle.
- It pumps it to the left ventricle, which in turn pumps off the purified blood to all parts of the body through arteries.
