Read the given para and name the parts of the heart. (AS1)
We have observed that the heart is divided into four chambers by muscular structure. Any structure that divides two chambers is known as the 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 inter atrial septum
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 is connecting the right atrium and right ventricle can be named as _____.
E. The aperture that is connecting the left atrium and left ventricle can be named _________.
Any structure that closes an aperture and allows one-way movement of materials is called as a valve. Now let us name the valves that are present in the chambers of the heart.
F. The valve that is present between the left atrium and left ventricle can be named as ________.
G. The valve that is present between the right atrium and right ventricle can be named as _______.
A. Inter atrial septum.
It is the tissue that separates the right atrium from the left atrium in the heart.
B. Inter ventricular septum.
It is the strong wall that separates the right and the left ventricles in the heart.
C. Inter atrial ventricular septum
It is the muscular septum which separates auricles and ventricles.
D. Right atrioventricular aperture
It is an aperture that connecting the right atrium and right ventricle.
E. Left atrioventricular aperture.
It is an aperture that connecting the left atrium and left ventricle.
F. Bicuspid (Mitral) valve.
The valve between the left atrium and left ventricle of the heart.
G. Tricuspid valve
The valve consisting of three cusps situated between the right atrium and right ventricle of the heart.
