Pulmonary arteries
Deoxygenated. The blood is carried by the pulmonary arteries from the heart to the lungs to replenish the oxygen.
Arteries carry blood away from the heart and veins carry blood into the heart. Blood moving from the heart to the lungs through the pulmonary artery has less oxygen than blood moving from the lungs to the heart through the pulmonary vein, but most arteries carry oxygen-rich blood with little carbon dioxide, and most veins carry deoxygenated blood with carbon dioxide and other wastes.
oxygen-poor blood to the lungs to get more oxygen and to release unneeded carbon dioxide for the lungs to remove
No, they carry blood rich with oxygen away from the heart to all the body.
Pulmonary arteries
During photosynthesis, carbon dioxide and oxygen are exchanged. The plant uses the carbon dioxide for the photosynthesis and expels oxygen.
The gases that are exchanged are oxygen and carbon dioxide.
alveolus
oxygen and carbon dioxide are exchanged in alveoli (singular alveolus).
diffusion
Arteries to arterioles to capillaries where exchange occurs. Oxygen and nutrients are exchanged for carbon dioxide and wastes.
Deoxygenated. The blood is carried by the pulmonary arteries from the heart to the lungs to replenish the oxygen.
Carbon dioxide
The gases that are exchanged are oxygen and carbon dioxide.
