What is 4th chambered heart?

Answer 1

A four chambered heart is a closed system and ensures that all blood passing through it is oxygenated. A three chambered heart has both oxygenated an non-oxygenated blood mixed in the single ventricle therefore the blood is at best only half oxygenated. A three chambered creature would suffer from exhaustion long before a four chambered creature.

However, it should be noted that there's a reason why frogs have a three-chambered heart. Though they breathe air using their lungs on land, they breathe through their skin using capillaries near their skin under water. When breathing through their lungs, ideally the blood entering the lungs should have CO2, so that it can be diffused out and O2 can be diffused in. When breathing through their skin, ideally the blood in the body has some CO2 so that it can be released through the skin, and O2 can be absorbed. In order to enable the frog to have CO2 in the blood in both the capillaries and lungs, it mixes the blood so that whether it's breathing through its lungs or its skin, it can manage either method passably. Although it is not specialized in breathing either on land or underwater, it is adapted to accomplish both passably, which is part of what makes it amphibian.

Answer 2

Only bees have a 5 chamber heart. there has been one reported human case in Russia, in which a boy was born with 3 ventricles, however doctors had to perform life saving surgery to repair the heart. Humans and most mammals have a 4 chambered heart, a mammal with a 5 chambered heart would not survive because blood would not get to where its supposed to be.

There is now a second case discovered in a baby boy in Louisville,KY. Information on the case has not yet been released to the public.

I was actually born with a 5 chambered heart. I am now in my 20s and still fine (without the surgery). Every once in a while I research any new information on the topic and have found random cases through my studies, including a man in his 70s who only recently discovered he had the condition. At the time I found out I had the condition (at age 7) I was told the likelihood of this mutation was 1:600,000,000. Hope the information is useful.

Answer 3

a four chambered heart has 4 ventricles... a ventricle is a tube leading to the heart... a ventricle has two purposes... one is to pump oxygen into the heart... the other pumps blood into your veins, the blood being pumped into your veins has already been bonded with oxygen... a 4 chambered heart allows oxygen to be pumped through 2 ventricles and also pumps blood throughout the body using 2 ventricles
