Question

How many chambers are found in the mammalian heart? list these chambers in the order in which blood flows through them?

Answer 1

The mammalian heart has four chambers: two atria and two ventricles. Blood flows through the chambers in the following order: right atrium, right ventricle, lungs, left atrium, left ventricle, and the rest of the body.

Step-by-step explanation:

In mammals, the heart consists of four chambers: two atria and two ventricles. The atria receive blood, while the ventricles pump blood out of the heart. The order in which blood flows through the chambers is as follows:

1. Oxygen-poor blood enters the right atrium from the body.
2. From the right atrium, blood flows into the right ventricle.
3. The right ventricle pumps the blood to the lungs to receive oxygen.
4. Oxygen-rich blood returns to the left atrium from the lungs.
5. From the left atrium, blood flows into the left ventricle.
6. The left ventricle then pumps the oxygenated blood out to the rest of the body.

Answer 2

hola!

Mammals have 4 Chambered heart.

→ Reason :

Mammals have more complex body design in comparision to those of other divisions.

So, they require more pumping of blood to more organs as well as, the heart and body in the case of these animals cannnot afford the intermixing of the bloods (oxygenated and deoxygenated blood).

This is why, mammals have four chambered heart.

Here's a example of Human Heart - [ refer the attachment. ]

→ Deoxygenated blood flows through Right Atrium and Right Ventricle respectively.

→ Oxygenated blood flows through Left Atrium and Left Ventricle respectively.

hope it helps!
