3. Human circulation and
circulatory system
The human circulation process happens when the
circulatory system transport nutrients and oxygen to all
the cells and and collects the waste substances to expel
them.

6. The circulatory system is made up of three
components:
Blood Heart Blood vessels

7. • Blood. It collects oxygen from the alveoli and
nutrients from the small intestine and
transports them to all the cells. It also collects
carbon dioxide and waste substances and
takes them to the respiratory organs and the
excretory system to be expelled.

8. • Heart. It is a hollow muscular organ that
pumps blood all around the body.

9. • Blood vessels. They are tubes through which blood circulates. There are
three types of blood vessels:
• Arteries. They transport the blood from the heart to the rest of the
body.
• Veins. They transport the blood from the body back to the heart.
• Capillaries. They are very thin vessels which go to all the cells of the
body.

13. The blood
The blood is a red liquid made up of cells
that float in a liquid called plasma.

14. • Blood cells. There are
several types of cells:
- Red blood cells. They carry
oxygen and make the blood
red.
– White blood cells. They are
defense cells and remove
bacteria and viruses from the
body.
– Platelets. They form blood
clots when a blood vessel
breaks.

15. • Plasma. It is a liquid made up of dissolved
water, salts and nutrients. It has also carbon
dioxide and other waste substances
