Question

13. 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 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 Improve your learning Free distribution by A.P. Government 71 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 valve. Now let us name the valves that are present in the chambers of the heart. f) The valve that is present between left atrium and left ventricle can be named as____________. g) The valve that is present between right atrium and right ventricle can be named as ___________

Answer 1

Answer:

b) Ventricular Septum

c) Atrioventricular Septum

d) Right Atrioventricular Aperture

e) Left Atrioventicular Aperture

f)  Mitral Valve

g) Tricuspid Valve

Hope my answer helps you also I don't know how to explain the answer since I cannot think of any.

Explanation:

Answer 2

Answer:

(b) Interventricular septum

(c) Atrioventricular septum

(d) Right atrioventricular aperture

(e) Left atrioventricular aperture

(f) Mitral valve

(g) Tricuspid valve

Explanation:

1. What is the interventricular septum?

• The interventricular septum divides the right and left ventricles.
• It is made up of muscular and fibrous tissues.
• It allows systemic blood flow in the heart, starting from the right atrium to tricuspid valve to the right ventricle, then in the lungs, and after that to the left atrium to left ventricle through the mitral valve.

2. What is the atrioventricular septum?

• An atrioventricular septum is present between the atrium and the ventricle.

• It is made up of membranous, muscular and thick fibrous tissues.
• It helps in the prevention of the mixing of oxygenated and deoxygenated blood.

3. What is the right atrioventricular aperture?

• The right atrioventricular aperture is the aperture that is connecting the right atrium and right ventricle.
• It is a large oval aperture which allows communication between the right atrium and the right ventricle.
• It ensures the blood flows in the correct direction.  

4. What is the left atrioventricular aperture?

• The left atrioventricular aperture is the aperture that connects the the left atrium and the left ventricle.
• It ensures blood flows in the correct direction between the left atrium and the left ventricle.

5. What is the mitral valve?

• A mitral valve is present between the left atrium and left ventricle, which facilitates oxygenated blood flow in the right direction and prevents backward flow of blood.
• Valve flaps open and close during each heart beat.

6. What is the tricuspid valve?

• A tricuspid valve is present between the right atrium and the right ventricle to prevent the backward flow of deoxygenated blood into the right atrium.
• This valve contains three thin flaps of tissue.
