Left Atrium. Chamber that receives oxygenated blood from the pulmonary veins and pumps it into systemic circulation. Superior Vena Cava. Carries (drains) blood from the head, neck, and upper limbs and empties in the right atrium.
The heart pumps blood to the lungs to be reoxygenated. Valves in our veins and the muscle contractions of our legs helps bring blood from the lower limbs to the heart.
The pulmonary artery carries blood from the heart to the lungs to recieve oxygen. The pulmonary vein then carries the blood back to the heart to be pumped to the body's limbs and organs.
They can be called limbs, appendages, extremities, or members.
The patient's airflow through the nose and mouth, blood pressure, heart activity, blood oxygen level, brain wave pattern, eye movement, and the movement of respiratory muscle and limbs.
The heart and the Lungs. The heart transfers the blood to the lungs where recently breathed in air will oxygenate the blood, they go from there throughout the body providing oxygen to limbs and the brain along with all the other organs and body parts.
Veins are the blood vessels that carry the blood that is low in oxygen back to the heart. Remember this trick; Arteries Away from the heart, veins back to the heart. I think that veins carry deoxygenated blood to the heart. For example, vena cava superior from head and upper limbs.
arteries
these are called flippers, I think

In the lungs. As we breathe, air travels down the pharynx (throat), into the trachea, and into the lungs. Its journey into the lungs begins with the trachea. The trachea branches off into two limbs called your bronchi. Two, because there is one for each of your lungs. Just like a tree, the limbs get smaller. These smaller limbs are called bronchioles. Now, we covered all that because at the very tips of the bronchioles are a collection of berry-like sac structures called avleoli. This is where the magic takes place (ok, I admit, it's not that dramatic). The air ( which contains oxygen) has traveled this far and it now fills the alveoli. The large pulmonary artery leading from the heart travels toward the lungs. As it progresses closer and closer it splits into smaller and smaller vessels, until it forms capillaries. These pulmonary capillaries are covering the alveoli. This can be visualised by thinking of a net or webbing around a round sac-like structure. The pulmonary capillaries are filled with blood that's been all around the body, and is now low in oxygen and rich in carbon dioxide. Back to the alveoli. The wall is so thin it's able to allow diffusion of oxygen into the capillaries. Diffusion is the tendency of the molecules of a substance to move from an area of high concentration to an area of low concentration. In this situation the alveoli are filled with oxygen rich air, and the blood in the pulmonary capillaries has very little. The oxygen diffuses into the capillaries replenishing those oxygen starved blood cells. Carbon dioxide moves the other way.
After the blood cells leave one of the four heart chambers, it flows through arteries, which then lead to the destination. Ie; limbs, organs, etc.
