 Given below is an image of the human heart with its main parts.

                                

 Following are the functions of the human heart:

(i) The human heart is a muscular pumping organ that pumps blood throughout the body.

(ii) Blood carries carbon dioxide from cells to the lungs for removal and transports oxygen from the lungs to the heart, thus the heart is indirectly responsible for the exchange of gases.

(iii) The heart pumps blood to all the cells of the body, thus it is responsible for providing oxygen and nutrients to each and every cell of the body.

(iv) Heart pumps hormones and other vital substances throughout the body. Due to the continuous flow of blood, the heart is also responsible for maintaining blood pressure in humans.
