Basics about the heart
- The human heart is designed as a pair of side by side pumps.
- Each side of the heart has a collection chamber for blood coming in through the veins, they are thin-walled and muscular, called atria.
- Each side has a thick walled muscular pump, called a ventricle which builds up enough pressure to send the blood out from the heart with a force referred to as blood pressure.
- The blood typically makes a circuit through the following range of blood vessels;
A large artery- Smaller artery branches- An arteriole- A capillary bed- A venule-
There are two routes for blood flow in the heart. The right side of the heart sends blood along the route called pulmonary circulation, and the left side of your heart sends blood along the route called systemic circulation.
