The document summarizes circulation and the circulatory system. It explains that the heart pumps blood through arteries, veins, and capillaries to distribute oxygen and nutrients to the entire body in systemic circulation. The document also describes pulmonary circulation, where blood picks up oxygen in the lungs and returns to the heart via pulmonary veins. It defines the functions of key blood vessels like the aorta, which carries oxygenated blood from the heart to the body, and the superior vena cava and capillaries.

1. Circulation is movement of
blood through the circulatory
system.

2. Our heart works like a
pump,and moves
blood through the
body. It never stops
beathing.

3. • Blood vessels are
tubes which transport
blood through the
circulatory sistem.
There kinds:Arteris,
veins capillares.

4. • Veins are the blood
vessels which carry
blood into the heart.

5. • Arteries are the blood
vessels which carry
blood away the heart.

6. • Capillaries are tiny
blood vessels which
connect arteries to
veins.They reach
every part of our
body.

7. • Pulmonary circulation
is the movement of
blood between the
heart and the lungs.

8. • Blood leaves the
heart through the
plumonary arteries
and goes to the lungs.
• In the lungs,the blood
absorbs oxigen and
releases carbon
dioxide. The blood
then returns to the
heart through the
pulmonary veins.

9. • Systemic circulation is the
movement of blood to the
rest of the body. Blood
with oxigen from the
lungs leaves the heart
through the aorta.
• It distributes nutritive
substances and oxigen
throughout the
body.finally,it returns to
the heart through the
vena cava.

10. What are the function of aorta?
The function of the aorta is carry
and distribute blood rich in
oxygen to the body.
What are the function of the
superior vena cava?
The function of the superior vena
cava is to receive the blood of
the half superior body.
What are the function of
capillaries?
The function of the capillary is the
transport of the oxygenated
blood to the organs and
tissues.
