Welcome to BLS CPR (Adult / Child / Infant)

Anatomy and Physiology
Anatomy of the Heart and Lungs
1. Heart
The heart beats continuously to pump blood to all parts of the body. It has four chambers: Right and left atrium and ventricles. Blood flows from the right side of the heart to the left side. The heart is connected to blood vessels (arteries and veins) which combined make up the circulatory system.

2. Lungs
Each person has two lungs underneath the ribcage: One on the left side and the one on the right. Their main function is to purify the blood i.e. from oxygen-poor blood to oxygen-rich blood.
