In the capillaries of an ice fish,how would oxygen get into tissues?

Question

Quizplus · Accepted Answer

In the capillaries of an ice fish, oxygen would diffuse from an area of higher concentration (the capillaries) to an area of lower concentration (the tissues) without the need for active transport, facilitated diffusion, osmosis, or hemoglobin receptors. This is because ice fish have no hemoglobin and very little myoglobin, making them particularly reliant on oxygen diffusion to sustain their metabolism.
