Answer to Question #143214 in Zoology for Zoology student#

Question

Discuss the basic blood flow of vertebrates and how their circulatory system works

Answer 1

Land vertebrates have lungs, the pulmonary vein to take blood from the lungs to the heart, and a double circulation, whereby the heart is effectively divided into two halves—one-half concerned with pumping incoming deoxygenated blood from the body to the lungs and the other with pumping oxygenated blood.
