Where does the blood have to pass through from the left atrium to the left ventricle?

Answer 1

Blood enters the heart through two large veins, the inferior and superior vena cava, emptying oxygen-poor blood from the body into the right atrium. The pulmonary vein empties oxygen-rich blood, from the lungs into the left atrium. Atrial contraction:blood flows from your right atrium into your right ventricle through the open tricuspid valve.When the ventricles are full, the tricuspid valve shuts. This prevents blood from flowing backward into the atria while the ventricles contract (squeeze). Atrial contraction: blood flows from your left atrium into your left ventricle through the open mitral valve. When the ventricles are full, the mitral valve shuts. This prevents blood from flowing backward into the atria while the ventricles contract (squeeze.) Ventricular contraction: blood leaves the heart through the pulmonic valve, into the pulmonary artery and to the lungs.Ventricular contraction: blood leaves the heart through the aortic valve, into the aorta and to the body. This pattern is repeated over and over, causing blood to flow continuously to the heart, lungs and body.

Answer 2

Blood flows through the following basic structures of the heart:

1. Right atrium
2. Tricuspid valve
3. Right ventricle
4. Pulmonary valve
5. Pulmonary arteries
6. Alveoli (in lungs)
7. Pulmonary veins
8. Left atrium
9. Mitral valve
10. Left ventricle
11. Aortic valve
12. Aorta

Answer 3

First, the Superior, and inferior vena cava take the "blue" blood to the right atrium. Next, the right atrium pumps the blood through a valve to the right ventricle. the right ventricle pumps the blood through another valve to the pulmonary artery. Then the pulmonary Artery sends the "blue" blood off to the alveoli. The alveoli are tiny air sacs within the lungs. In the alveoli, gas exchange happens that is called diffusion. Oxygen into the blood, and carbon dioxide to the alveoli to be exhaled. The blood then Travels to the Pulmonary vein, through a valve, to the left atrium. Next, the left Atrium pumps the blood through another valve to the left ventricle. Last, the "red" blood travels to the largest blood vessel in the body, which is the Aorta. Then the blood is sent to the entire body, where it comes back to the heart later, to repeat the process's.

Answer 4

Venous blood enters into the right atrium, empties into the right ventricle through the tricuspid valve. from the left ventricle, blood flows through the pulmonary artery to the lungs where CO2/O2 gas exchange takes place. Oxygenated blood flows to the left atrium into the left ventricle through the mitral valve. From the left ventricle, blood is pumped out through the aortic valve, into the aorta where blood then enters the systemic circulation.

Answer 5

venous blood goes up to the lungs in order to get oxygized

Answer 6

right atrium.

Answer 7

A valve

Answer 8

it doesn't
