Blood with no oxygen (the blood that flows to the heart picks up oxygen from the lungs).
Aerobic fitness is the ability of the heart and lungs to deliver oxygen. This oxygen meets body needs under a variety of circumstances.
The pulmonary arteries deliver blood to the lungs from the heart so it can be oxygenated.
The heart and lungs work together to deliver oxygen to and remove carbon dioxide from the body's tissues. The brain uses this oxygen to function.
The pulmonary arteries deliver blood to the lungs from the heart so it can be oxygenated.

After leaving the heart, the blood travels through the arteries to deliver oxygen and nutrients to the body's tissues. It then returns to the heart through the veins to be pumped to the lungs for oxygenation.
The pulmonary veins deliver blood to the left atrium from the lungs.
veins move blood to the heart; arteries move blood away from the heart. Blood goes from the heart to the lungs to get oxygen, then back to the heart, then to the body (to deliver the oxygen), then back to the heart, where it starts the process over again.
The heart is both medial AND deep to the lungs.
Capillary beds carry deoxygenated blood into veins to return the blood to the heart and then to the lungs to pick up oxygen.
The left side of the heart is responsible for pumping oxygen-rich blood out to the body through the aorta, so that it can deliver oxygen (O2) to the tissues and organs. This side receives oxygenated blood from the lungs and pushes it out to the rest of the body.
