Summary:
- Pulmonary circulation is the part of the circulatory system that carries blood between the heart and lungs.
- Oxygenated blood leaves the right ventricle through pulmonary arteries, which transport it to the lungs.
- In the lungs, the blood gives up carbon dioxide and picks up oxygen.
- The oxygenated blood then returns to the left atrium of the heart through pulmonary veins.
- The systemic circulation carries the blood between heart and body.
- It is illustrated in Figure below.
- The main function of thecirculatory system is to pump blood carrying oxygen around the body.
