Blood that leaves the pulmonary alveoli are fully oxygenated whereas the blood entering them are partially deoxygenated.
Yes, capillaries form a network around the alveoli. It is through the alveolar walls and into the capillaries that oxygen enters the blood stream. Carbon dioxide leaves the blood by the reverse route.
The blood that enters the alveoli is deoxygenated, having traveled from the body's tissues and containing a higher concentration of carbon dioxide. In contrast, the blood that leaves the alveoli is oxygenated, as it has picked up oxygen from the lungs and released carbon dioxide. This exchange occurs during respiration, where oxygen diffuses into the blood while carbon dioxide diffuses out into the alveolar air. Thus, the composition of gases in the blood changes significantly during this process.
The blood pressure is usually high when blood leaves the small arteries and enters the capillaries.

It is carbon dioxide which is collected from different organs of the body by blood
NUTRIENTS AND OXYGEN also water, minerals, and vitamins
carbon dioxide
Oxygen leaves the lungs and enters the blood during the process of respiration. When we inhale, oxygen-rich air fills the alveoli in the lungs, where oxygen diffuses across the alveolar walls into the bloodstream. This oxygen binds to hemoglobin in red blood cells and is then transported to tissues throughout the body. Additionally, carbon dioxide, a waste product of metabolism, moves from the blood into the lungs to be exhaled.
the answer is quite simple ...... carbon dioxide is the waste gas and it leaves the blood and then leaves the body when you exhale.
Circulatory system
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.
