Respuesta :

1. Atrium

2. Ventricle

3.left ventricle

4. they pump blood throughout the body

5.superior vena cava

6. Pulmonary vein

7.Four heart valves control the flow of blood through the heart. They act as one-way doors, opening to let blood exit or enter a chamber, then closing to keep blood from flowing backward.

Answer:

1. The right atria is a blood vessel that receives blood from the body. This blood is oxygen-depleted. (vein carry them)

2. ventricle

3. Left ventricles

4. Because it needs to pump blood over a longer distance and the systolic pressure in this chamber is extremely high.

5. The superior and internal vena cava are the veins that transport blood into the right atrium, which is the upper chamber of the heart.

6. heart to lungs ( pulmonary artery)

   lungs to heart ( pulmonary veins)

7. arteries

8. The valves are meant to allow blood to flow forward only. A valve opens when each chamber contracts, allowing blood to flow out. The valve closes when the chamber relaxes, preventing blood from leaking back into the chamber and allowing the chamber to fill with blood again.

Explanation:

The veins direct all impure blood towards the right atrium chamber, which leads to the heart. The blood is then pushed into the right ventricle, where it is pumped into the lungs via the pulmonary arteries. The blood picks up oxygen in the lungs and returns to the heart via the pulmonary veins, which lead to the left atria and then the left ventricle. The blood is subsequently pumped to the major artery, which provides oxygenated blood to the entire body.
