The blood pressure is usually high when blood leaves the small arteries and enters the capillaries.

NUTRIENTS AND OXYGEN also water, minerals, and vitamins
Alveoli (plural) and alveolus (singular)
carbon dioxide
Blood that leaves the pulmonary alveoli are fully oxygenated whereas the blood entering them are partially deoxygenated.
After blood leaves the arteries, it enters smaller blood vessels called arterioles which help supply the body with blood and then they break down into even smaller vessels called capillaries which then carry the oxygenated blood to the tissues, organs and all cells of the body. Then after the body uses up all the oxygen, the blood becomes deoxygenated which then enters venules and then veins which lead up back to the vena cava of the heart. It then enters the right atrium then passes through the tricuspid valve and then enters the right ventricle, then leaves the heart via the pulmonary artery which enters the lungs to oxygenate the blood.
the answer is quite simple ...... carbon dioxide is the waste gas and it leaves the blood and then leaves the body when you exhale.
Oxygen (O2) enters the blood through inhalation and is circulated throughout the body. Carbon Dioxide (CO2) is filtered out of the blood as a waste product and exhaled.
For an average adult human, 5 percent of the blood supply enters or leaves the heart with each heartbeat.
