The circulatory system transports oxygen, nutrients, and waste products around the body. It includes the heart, blood vessels, and blood. The heart pumps blood through arteries, which branch into capillaries where oxygen and nutrients are exchanged, and veins return blood back to the heart. Blood contains plasma and blood cells like red blood cells, which carry oxygen, and white blood cells, which fight infection. The circulatory system has two circuits - pulmonary circulation carries blood to the lungs to pick up oxygen and release carbon dioxide, while general circulation transports oxygenated blood to tissues and returns carbon dioxide back to the heart.

takes oxygen and
nutrients to all the tissues
of carbon dioxide.Then it
takes them to organs that
eliminate them.
 The circulatory system
includes the heart,the
blood vessels and the

4. BLOOD VESSELS:are special tubes that carry blood all
around the body.There are three tyoes of blood
vessels:arteries,veins and capillaries.
ARTERIES:carry blood aways from the heart
VEINS:carry the blood back to the heart.
CAPILLARIES:are tiny blood vessels that connect the
smallest arteries to the smallest veins.

5. Reed blood cells.
BLOOD:contains liquid plasma and solid blood cells.
Platelests:help to form a solid clot when thre is a cut
in a blood vessel.
Red blood cells: carry oxygen.
White blood cells:fight infections in the body.

6. PULMONARY CIRCULATION.  GENERAL CIRCULATION.
Oxegenated blood flows from the heart to
Blood fows from the heart to the
the rest of the body.The oxygen goes into
lungs.Inthe lung, the blood releases
tissues of the body and the blood picks up
carbon dioxide and picks up oxygen. carbon dioxide.

7. Exercise: Walk or do sport for 30
minutes or more every day.
Eat healthy food:Eat lots of fresh
fruit, vegetables,
, beans and fish.
Stay away from cigarette
smoke.Smoking is very bad for
your respiratory and circulation
systems.

8. The sweat glands and
the urinary tract.

9. They produce sweat- a liquid that contains water,
waste products and mineral salts.

10. THE URINARY TRACT:
The main parts of the urinary
tract are kidneys,the
urethers,the bladder and the
urethra.
