The document discusses the circulatory, excretory, and respiratory systems. It explains that the circulatory system consists of blood, blood vessels, and the heart. Blood carries oxygen, nutrients, waste products, and carbon dioxide throughout the body via arteries, veins, and capillaries. The heart pumps blood through two circuits - pulmonary and systemic circulation. The excretory system includes kidneys, ureters, bladder, and urethra which filter blood, produce urine, transport and store urine, and expel urine from the body. Sweat glands are also part of the excretory system, eliminating waste and cooling the body through sweating.

- It is a liquid substance in our body that gives
nutrients and oxygen to all the body cells. It also
transport waste products and CO2.
- They are tubes that transport blood throughout
the body.
- It is a special type of muscle and acts as a pump
to send blood around the body.
Match the parts of the circulatory system and
their definitions.

6. - Plasma. It is a clear fluid which transports nutrients and waste
around the body.
- Red blood cells. These carry oxygen from the lungs to all body
cells.
- White blood cells. These protect the body from germs and
disease.
- Platelets. These are
fragments of old cells.
They help to stop bleeding
from wounds.
Look, read and answer.

1. What are the three types of
blood cells?
2. What do they do?
3. Why do you think blood is
red?

7. Look and think. What blood vessel do nutrients, oxygen and
carbon dioxide (CO2) exchanges take part?

8. Look and think. What blood vessel do nutrients, oxygen and
carbon dioxide (CO2) exchanges take part?

Capillaries have very
thin walls. This allows
for nutrients and
oxygen to pass into
the body cells, and for
carbon dioxide (CO2)
and other waste
products to leave the
cells.

movements in your notebook.

10. BLOOD SAVES LIVES
In Spain, a blood transfusion is needed every two minutes! Blood
transfusions are required after traffic accidents, in a lot of
operations and in the treatment of some illnesses.
- Where can you donate
blood?
- Why is it important to
volunteer?

Research what the
different blood types
are and tell me what is
yours.
Read and discuss.

12. CIRCULATION
Blood moves constantly in the circulatory system through two
separate circuits: the pulmonary circuit and the systemic circuit.
2
Watch this video about pulmonary and systemic
circulation. Then, contribute to make up a P.E. circuit to
explain circulation.
Taking notes
while watching
the video is a
good idea.

13. CIRCULATION AND HEALTH
In order to look after our circulatory system...
-We should eat a healthy diet. Consume vegetable fats, like olive oil,
and foods that are high in iron, like pulses.
-We shouldn’t eat too many carbohydrates and fats.
-We should use salt in moderation.
-We should exercise regularly.
-We shouldn’t smoke.
-We shouldn’t consume
excessive alcohol.

14. Excretion is the elimination of waste products from the blood.
These substances are toxic and need to be eliminated.

a. They carry urine from the kidneys to the
bladder.
b. It stores urine until it leaves the body.
c. It is a tube that releases urine out of the body.
d. They filter the blood, retain waste products and
use them to produce urine. They also reabsorb
good nutrients and water and return them to
the blood.
