Summary
- Nutrients and oxygen are required by cells for cellular respiration. These are
transported by blood to the various cells.
- Carbon dioxide and other wastes need to be transported from the cells to the
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.
- The right side of the heart receives oxygenated blood from the lungs and sends
it via arteries to all parts of the body.
- The lymphatic system is composed of lymph vessels, lymph nodes, and organs.
- Lymph vessels assist the circulatory system and all the cells of the body by
removing wastes, germs and excess water from the tissue fluid.
