Provide an example of an organism that has pulmonary vascular system and discuss why this type of vascular system is more efficient for organisms that have a high metabolic demand for oxygen?
PULMONARY VASCULAR SYSTEM is seen in mammals and birds. These organisms like lion, tiger, leopard, chita, elephant , humans etc and birds. They require faster, efficient , and more quantitative vascular system.
This is required because of high demands of oxygen, high metabolic rates , warm blooded ness, maintaining homeostasis, high physical movement activities , large bodies, and high resoiration rates.
This more efficient system because it supports no mixing of oxygenic and deoxygenated blood, double circulation, 4 chambered heart. Pulmonary cappilarh level diffusion of gases.
