The capacity can be improved by surface movement and water circulation such as through aeration, which not only improves oxygen exchange, but also waste decomposition rates.

Lack of this neurotoxic affect would indicate that fatal cases involving the cardiovascular system are the result of direct muscle injury or reduced oxygen exchange.

Extensive vasculature around the parabronchi are where oxygen exchange takes place.

The laws of oxygen exchange will not permit it.

A greater number of capillaries also allows for greater oxygen exchange in the network.

This very sturdy flat calcareous structure has a small perforation to allow for oxygen exchange.

At the dependent region smaller volumes mean the alveoli are more compliant (more distensible) and so capable of wider oxygen exchanges with the external environment.

The gills are composed of comb-like filaments, the gill lamellae, which help increase their surface area for oxygen exchange.

It affects the ecology of its habitat by forming mats on the water surface, reducing sunlight penetration and oxygen exchange.

Together, the two reduce the amount of oxygen exchange in the lungs and thicken the lining of the airways.
