Genetics is the scientific study of heredity.
Transport of blood under high pressure is done through the concerted efforts of the heart and arteries.
<h2>The circulatory system is the network of the heart, arteries, veins, and capillaries responsible for the movement of blood around the body.</h2>
Transporting blood under high pressure can be explained in the following steps:
- Contraction of the heart ventricles creates blood under high pressure
- High pressured blood is removed from the heart through the arteries. In addition, the arteries are able to contract and expand, thus are elastic
- The lumen of the arteries is narrow thus helping in maintaining high pressure
As a result of the above, the high pressure of blood is maintained and transported to the extremities of the body.
