Chapter 44, Problem 11TYU
Summary Introduction
To explain: The benefits of the adaptation of having a heart with four chambers in birds and mammals.
Introduction: In vertebrates, the circulatory systems of the animals have been modified with evolution, so that animals can adapt to their lifestyle. Some vertebrates have a single circuit for circulation, and some have the double circuit for the blood flow. The heart of the birds and mammals is evolved into four chambers, which is a beneficial adaptation to their life.

Students have asked these similar questions
1) Evolution of the vertebrate Circulatory system: How has the circulatory system in
vertebrates changed from the simplest vertebrate to the most advanced?
2) What do those advancements allow? The most advanced vertebrates have the most complex/fancy organs. What have the advancements of these organs allowed birds and mammals to do those other vertebrates cannot?
8. We discussed fish, amphibian, and mammalian hearts, but didn’t spend much time on reptiles and birds. Please compare and contrast the anatomy of the heart ina) most reptiles (turtles, snakes, lizards)
in terms of number of atria, number of ventricles, total number of chambers, and development of the aorta from aortic arches (left, right, or both). Use a table, not text. Also, include a drawing showing the basic template of dorsal aorta, ventral aorta, and six aortic arches, along with drawings showing the modified patterns of aortic arches in a-d above.
Mammals and birds evolved from different reptilian lineages (therapsid reptiles and saurischian dinosaurs, respectively). Most reptilian hearts have three chambers (2 atria and 1 ventricle), yet the heart of both mammals and birds have four chambers.
Explain how these two groups ended up with similar structures.
Explain the evolutionary advantage of a four-chambered heart.
