Answer 2

The heart is a pump, which moves the blood. The arteries and veins are the pipes through which the blood flows. The lungs provide a place to exchange carbon dioxide for oxygen. The heart is a hollow, muscular organ, which functions as a pump for the movement of blood through the body.This system has three main functions: Transport ofnutrients, oxygen, and hormones to cells throughout the body and removal of metabolic wastes (carbon dioxide, nitrogenous wastes).

Heartbeat is defined as the pulse of yourheart, or a single short moment, or something that acts as a unifying force. When your heartpulses and pumps blood throughout your body, this is an example of a heartbeat.
