flow of blood through the heart w/ labeling right and left
Starting @ vena cava
Does it go through the Right and Left Pulmonary Veins or only the right side?
does it go through the capillaries of both lungs?
Here is what I have:
Vena Cava
Right atrium
Tricuspid valve
right ventricle
pulmonary semilunar valve
R+ L pulmonary artery
Lung Capillaries
pulmonary veins??
left atrium
bicuspid valve
Left ventricle
aorta
Since this is not my area of expertise, I searched Google under the key words "blood flow in heart" to get these possible sources:

In the future, you can find the information you desire more quickly, if you use appropriate key words to do your own search.

The flow of blood through the heart begins at the vena cava. There are two types of vena cava: the superior vena cava and the inferior vena cava. The superior vena cava brings deoxygenated blood from the upper body, while the inferior vena cava brings deoxygenated blood from the lower body.
From the vena cava, the blood enters the right atrium of the heart. The right atrium contracts, pushing the blood into the right ventricle. Next, the right ventricle contracts, forcing the blood out of the heart through the pulmonary artery.
At this point, the blood is still deoxygenated and is directed towards the lungs. Once it reaches the lungs, it branches out into smaller arteries called the pulmonary arteries. The blood then reaches the capillaries in the lungs, where it undergoes gas exchange. Oxygen is picked up, and carbon dioxide is released. The newly oxygenated blood returns to the heart via the pulmonary veins.
Now to answer your specific questions:
1. Does the blood go through the right and left pulmonary veins or only the right side?
- The blood goes through both the right and left pulmonary veins. The right lung is supplied by the right pulmonary veins, and the left lung is supplied by the left pulmonary veins. The pulmonary veins carry oxygenated blood back to the heart.
2. Does the blood go through the capillaries of both lungs?
- Yes, the blood does go through the capillaries of both lungs. The purpose of the capillaries in the lungs is to allow for the exchange of gases, specifically oxygen and carbon dioxide. Oxygen diffuses from the lung's capillaries into the blood, while carbon dioxide diffuses out of the blood into the lungs. This gas exchange takes place in the capillaries of both lungs.
I hope this helps in understanding the flow of blood through the heart, as well as how it reaches the lungs and goes through their capillaries.
