Question

Read the given para and name the parts of the heart. We have observed that the heart is divided into four chambers by muscular structure. Any structure that divides two chambers is known as septum. Now let us try to name the septa present in the heart
a) The septum that divides the two atria can be named as _____________
b) The septum that divides the two ventricles can be named as___________.
c) The septum that divides the atrium and ventricle can be named as________.
The holes that connect two chambers are called apertures. Let us try to name the apertures
which connect the atria and ventricles?
d) The aperture that connects the right atrium and right ventricle can
be named as_______.
e) The aperture that connects the left atrium and left ventricle can be
named ___________

Answer 1

Answer:

The heart is made up of four chambers. The upper two chambers are called atria (singular: atrium) and the lower two are known as ventricles (singular: ventricle).

Muscular walls, called septa or septum, divide the heart into two sides.

On the right side of the heart, the right atrium and ventricle work to pump oxygen-poor blood to the lungs.

On the left side, the left atrium and ventricle combine to pump oxygenated blood to the body.
