Why we need a circulatory system?
All cells in the body need to have oxygen and nutrients, and they need their wastes removed. These are the main roles of the circulatory system. The heart, blood, and blood vessels work together to service the cells of the body.
When we do not have a circulatory system then anything was not transported from one place to another in our body. For example, if we do not have a circulatory system. Then we do not have blood, blood vessels, excretory system, etc. Without blood, the waste material of the body does not throw out and many diseases are obtained in our bodies. Another example was that we do not get energy. Actually when we inhale oxygen lungs transport it to the heart with the help of blood. So, we need the circulatory system.
