Best Answer

The lungs take in oxygen, this oxygen travels down to the alveoli (thin, permeable sacs), which are covered in blood vessels, and the oxygen travels into the blood due to a pressure difference and CO2 goes from the blood to the lungs to be exhaled. The body needs that oxygen for almost every system in the body.

Is Blood pumped by right ventricle oxygen-rich or oxygen-poor?

Yes, the right ventricle transports oxygenated blood to the lungs.


What happens after your right vertical pumps oxygen-poor blood from the heart?

it goes to the lungs and get oxygenated then returns to the heart to be pumped to the body


What organ converts blood from oxygen-rich to oxygen-poor?

oxygen rich blood gets pumped out of your heart to your arteries which carries the blood to your muscles. then your muscles use the oxygen. oxygen poor blood goes into your veins to go back into your heart. then it goes through a cycle that takes your blood to your lungs, to get oxygen. this process is repeated.


Do we have oxygen poor blood in your lungs?

no you have oxygen high blood.


What is blood before it goes to the lungs?

Blood goes to the lungs oxygen poor and comes out of the lungs oxygen rich.


What are the characteristics of blood pumped by right ventricle?

has poor oxygen in it


What type of blood do the lungs receive?

Oxygen Poor blood. The lungs add the oxygen to the blood and then release the carbon dioxide.


Why does blood circulate from the heart to the lungs?

The oxygen poor blood (not enough oxygen) goes to the lungs to get more oxygen to turn into oxygen rich blood (has plenty of oxygen)


How does blood flow through the lungs throughout the body?

Blood is pumped by the heart. Blood leaves the heart via the arteries and returns to the heart via the veins. Blood returning to the heart goes to the lungs where it is oxygenated then pumped around the arteries


What do veins carry oxygen poor blood into?

The lungs, where they become oxygen-rich blood


Is the blood flowing from the heart to the lungs rich or poor in oxygen?

poor


Where does oxygen leave the blood?

When the blood is pumped through the body, it delivers essential oxygen for cells to function. When the blood becomes oxygen-poor, it goes past the lungs, in which the gas exchange, where the oxygen poor blood releases carbon dioxide, which is a bi product of the system (and is to be breathed out), and retrieves the air from the lungs, to begin the process again.
