1. BIOLOGY

3. FUNCTION
Helps keep your body at the RIGHT
TEMPERATURE
Carries HORMONES to the body cells
SENDS ANTIBODIES to fight infection
Contains CLOTTING FACTORS to clot blood and
the bodies tissue to HEAL
Transport OXYGEN and NUTRIENTS throughout
the body
Remove waste materials such as CARBON DIOXIDE

6. Fluid part of blood
&
Carries carbon
dioxide, hormones and waste

8. Contain haemoglobin which
carries oxygen
&
Made in the bone marrow. The
more you train the more red
blood cells are made.

10. Important part of the immune system,
they produce antibodies and
destroy harmful micro organisms

12. Clump together form clots
&
Protect the body by stopping
bleeding

15. The heart pumps blood out through one main artery
called the dorsal aorta. The main artery then divides
and branches out into many smaller arteries so that
each region of your body has its own system of
arteries supplying it with fresh, oxygen-rich blood.

17. Veins receive blood from the capillaries after the
exchange of oxygen and carbon dioxide has taken
place. Therefore, the veins transport waste-rich blood
back to the lungs and heart. It is important that the
waste-rich blood keeps moving in the proper
direction and not be allowed to flow backward. This is
accomplished by valves that are located inside the
veins. The valves are like gates that only allow traffic
to move in one direction

19.  Unlike the arteries and veins, capillaries are very thin and fragile.
 The capillaries are one epithelial cell thick.
 The exchange of oxygen and carbon dioxide takes place through the
thin capillary wall.
 The red blood cells inside the capillary release their oxygen and take
in carbon dioxide and waste products
