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
