3. CARDIOVASCULAR SYSTEM

4. CARDIOVASCULAR SYSTEM

The cardiovascular system carries кисень
and поживні речовини to all of the cells in
the body. It also picks up двоокис
вуглецю and other відходи that the body
produces. The main components of this
system are the heart, blood vessels, and
blood.

5. The Heart's Role in the Cardiovascular System

The human heart is a hollow, muscular organ about the
size of a fist. Its job is to pump blood through a network
of blood vessels. These vessels form коло, which starts
at the heart, goes out through your body, and then ends
back at the heart again.
When talking about the heart, it is helpful to look at its
components:
камери
серцеві клапани
кров'яні судини, including артерії та вени.

6. Heart Chambers

The heart is divided into four chambers:
Праве
передсердя
Ліве передсердя
Правий шлуночок
Лівий шлуночок

7. Valves of the Heart

In a healthy heart, there are valves that keep
blood flowing in a one-way direction. When they
open, they only let the right amount of blood
through, and then they close to keep blood from
flowing backwards між ударами серця.
Коло кровообігу begins with blood entering the
right atrium of the heart. When the heart beats,
blood flows from the right atrium into the right
ventricle through a valve.

8.

From the right ventricle, blood flows through another
valve and then to легенів, where it picks up oxygen.
From the lungs, it flows back into the left atrium of the
heart and through мітральний клапан into the left
ventricle. From the left ventricle, blood is pumped
through the aortic valve and into the aorta, where it goes
out to the rest of the body, bringing oxygen and nutrients
to your cells.
For the human heart to work right, each of the four
chambers must скорочуватися at just the right time.
Your heart has an electrical system that helps coordinate
this timing.

9. Arteries and Veins of the Heart

The arteries are major blood vessels connected to the human heart:
The ………………. artery carries blood pumped from the right side of the
heart to the lungs to pick up a fresh supply of oxygen.
………….. is the main artery that carries oxygen-rich blood pumped from
the left side of the heart out to the body.
The ………………..artery are the other important arteries attached to the
heart. They carry oxygen-rich blood to the heart muscle, which must have
its own blood supply to function.
The veins are major blood vessels connected to the human heart:
The ………………veins carry oxygen-rich blood from the lungs to the left
side of the heart so that it can be pumped out to the body
Порожнисті вени are two large veins that carry oxygen-poor blood from
the body back to the heart.

10. The Role of Blood Vessels

There are three main kinds of blood vessels
within the cardiovascular system:
…………………..
…………………..
…………………..

11. Arteries

Arteries are large blood vessels that carry
blood from your heart to the rest of your
body. This blood is rich in oxygen and
nutrients. As arteries get farther away from
the heart, they begin to branch and
become smaller and smaller.

12. Capillaries

The smallest branches are called
capillaries. Here, oxygen is transferred
from the blood into your cells. In
exchange, the wastes from your cells,
including carbon dioxide (CO2), are
transferred into the blood.

13. The Veins

Just beyond this area, the capillaries begin
зливатися and eventually form larger
vessels, called veins, which lead back to
the heart. As veins carry the CO2-rich
blood back to the heart, other organs filter
out and dispose of the waste products.

14.

As кров позбавлена кисню makes its way
back through the heart and lungs, it picks
up oxygen and nutrients. It also releases
the CO2 into the air you breathe out. The
heart then pumps the blood out through
the arteries, and the cycle is repeated.

15. The Role of Blood

The last main component of the cardiovascular
system is blood. Blood flows throughout your entire
body, carrying oxygen and nutrients to all of your
cells and taking away the waste products that they
produce. Blood is a fluid that carries several different
kinds of cells.
The three types that we will talk about are
еритроцити, лейкоцити, and спеціальні
фрагменти клітин, які називаються
тромбоцити.

16. RBC, WBC and Platelets

Red blood cells carry oxygen to your organs and
take carbon dioxide away from them.
White blood cells help your body fight infection
from bacteria and viruses. They play a very
important role in your body's immune system.
Platelets help to seal off a blood vessel when it
has been cut or torn, so they act like your own
natural bandage. They also stop blood from
flowing out of the damaged area.

17. Throughout your body thousands of miles of blood cells run to every living organ or tissue. The function of your body is dependant on a constant supply of blood and its components

4.
The cardiovascular system carries waste
products that the body produces to all of the
cells in the body.
The main components of this system are the
heart, blood vessels, and blood.
The circulatory loop begins with blood entering
the right ventricle of the heart.
The pulmonary veins carry oxygen-rich blood
from the lungs to the left side of the heart so
that it can be pumped out to the body

20. TRUE OR FALSE

5. The venae cavae carry blood pumped from the right
side of the heart to the lungs to pick up a fresh supply of
oxygen.
6. The aorta is the main artery that carries oxygen-rich
blood pumped from the left side of the heart out to the
body.
7. The coronary arteries carry oxygen-poor blood to the
heart muscle, which must have its own blood supply to
function.
8. The pulmonary arteries are two large veins that carry
oxygen-poor blood from the body back to the heart.
9. Arteries are large blood vessels that carry blood from
your heart to the rest of your body.

21. TRUE OR FALSE

10. Red blood cells help your body fight infection from
bacteria and viruses. They play a very important role in
your body's immune system.
11. Platelets carry oxygen to your organs and take carbon
dioxide away from them.
12. White blood cells help to seal off a blood vessel when
it has been cut or torn, so they act like your own natural
