The Circulatory System

The circulatory system
The circulatory system is a vast network of organs and vessels that is responsible for the flow of blood, nutrients, hormones, oxygen and other gases to and from cells. Without the circulatory system, the body would not be able to fight disease or maintain a stable internal environment — such as proper temperature and pH — known as homeostasis. (Live Science, 2017)
Main keys roles
The most important role of the cardiovascular system is maintaining a normal, healthy, balanced movement.
The cardiovascular system is often called the blood vascular, or simply the circulatory system. It consists of the heart, and a closed system of vessels called arteries, veins, and capillaries.

The Effect of exercise on the heart
Your heart pumps blood at a fast pace to pump extra food and oxygen to the muscles. When, you exercise your body, has to pumps more blood. This is because when you exercise, the cells that are in your muscles need more energy to move. Your muscles get this energy from respiration. This chemical reaction uses up oxygen to release energy from glucose. This then travels in the blood, so if your muscles need more oxygen and glucose, they get it from the blood. So now we know that when you exercise, your body pumps more blood, which makes your pulse rate faster.
