exterior. This is also transported via blood.
- Blood is pumped through the heart under high pressure to the various parts of
the body.
- The heart is divided into the left side of the heart and the right side of the
heart.
- The left side receives deoxygenated blood from the body via veins and sends it
to the lungs to be oxygenated.

it via arteries to all parts of the body.

- Lymph vessels assist the circulatory system and all the cells of the body by
removing wastes, germs and excess water from the tissue fluid.
