Explanation / Answer
the affinity of the hemoglobin for changes with pH.
what is the affecting the pH of the blood
the blood changes its pH based on the amount of carbon dioxide dissolved
As blood nears the lungs, the carbon dioxide concentration decreases, causing an increase in pH. This increase in pH increases hemoglobin's affinity for oxygen through the Bohr effect, causing hemoglobin to pick up oxygen entering the blood from lungs so it can transport it to tissues
arteries have thicker walls because it carries high pressure blood from the heart
Fish: single loop circulation blood passes through heart once before going to tissue
Amphibians: double loop circulation blood goes through heart twice but mixes with deoxygenated blood from the tissue
Mammals: double loop circulation complete separation of oxygenated and deoxygenated blood
Path of blood flowing in fish
