Blue whales are mammals and just like us have lungs with alveoli and transport oxygen in blood via a closed circulatory system. However, in contrast to us, blue whales are the biggest animals that have ever lived. Compared to a human, the total distance that oxygen has to diffuse to reach cells in blue whales is blank , while the distance of bulk flow for oxygen in blue whales is

Roughly the same, larger.

Explanation:

The mammals have four chambered heart and double circulation occurs in mammals that separates the oxygenated and deoxygenated blood in mammals and saves the energy.

The oxygen needs to diffuse in each and every cell of the body. The distance of the oxygen diffusion is almost same in the whales and other mammals. The distance of bulk flow of oxygen depends on the total surface area and inversely proportional to it. The humans body small is small as compared to whales and has less distance where blue whale has the large distance of bulk flow for oxygen.

Thus, the answer is roughly the same, larger.

endo:

regulates body hormones, aldosterone, vasopressin

neural:

signal, regulates body using electric signals, reflex

endo has to do with hormones; aldosterone and vasopressin are both hormones. i also had this question and got it right : d
