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.

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.

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.

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.

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.

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.

transferred from the blood into your cells. In exchange, the

wastes from your cells, including carbon dioxide (CO2), are transferred into the blood.

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.

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.

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.

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.

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

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.
