Lungs
Your lungs refine oxygen from the other gases in air because the gases diffuse through the cell walls in the alveoli in your lungs through osmosis (higher concentration of gases in the air than in the blood, so gases move from the higher concentration to the lower concentration) where they contact the red blood cells. The hemoglobin in the red blood cells binds to the oxygen and leaves all the other gases alone. It moves on from the lungs and delivers the oxygen to the rest of the body. It's the hemoglobin that does the work.
It depends on what kind of animal it is. If it is an amphibian, the red blood cells will have a nucleus. Human red blood cells do not have nuclei.
the perch has three chambers, and the left atrium releases oxygen rich blood to the body and right atrium brings oxygen poor blood to the heart.
More oxygen, for the pumped blood circle through the body and the body consumes more oxygen and carries more oxygen than it carries carbon-dioxide.
A frog is an amphibian, but adult frogs do not have gills. They absorb oxygen from the water through their skins, using special blood vessels. If the oxygen level in water is too low, frogs will move around to increase the water flow across the skin. Some frogs have creased skins that can increase their surface area. (see related question)
The amphibian's heart does pump out a mixture of oxygen-rich and oxygen-poor blood. They are vertebrates, and this is how vertebrates' circulatory systems work.
Blood delivers oxygen.
No, a Capillary is a small blood vessel that delivers oxygen and other nutrients to cells.
Blood delivers oxygen.
