The Transport in
Animals
The transport system in animals plays a crucial role in delivering nutrients,
oxygen, and hormones throughout the body. Let's explore the fascinating
world of circulatory systems!

The Heart and Its Functions

Structure
The heart consists of four chambers: two

atria and two ventricles, working together
to pump blood.
It receives deoxygenated blood from the
body, pumps it to the lungs for
oxygenation, and then receives
oxygenated blood to pump throughout
the body.

Mechanism
The heart contracts rhythmically,
ensuring a continuous flow of blood.
