Right atrium receives deoxygenated blood. Vitamins and hormones are transported via blood. Tricuspid valve is present between right atrium and right ventricle. A bundle of nodal fibres, atrioventricular bundle (AV bundle) continues from the AVN which passes through the atrio-ventricular septa to emerge on the top of the interventricular septum and immediately divides into a right and left bundle. These branches give rise to minute fibres throughout the ventricular musculature of the respective sides and are called purkinje fibres.

Assertion : Human heart is myogenic, as it generates its own electrochemical impulse. Reason : It is not under any neural or endocrine control.
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Both Assertion and Reason are incorrect
Explanation:
Human heart is myogenic, as it generates its own electrochemical impulse. The heart is composed of cardiac muscle, an involuntary muscle tissue that is found only within this organ.The cardiac muscle is self-exciting, meaning it has its own conduction system. Thus, the assertion is true and the reason is correct explanation of Assertion.

SA node is located in
1 Upper left corner of right atrium
2 Lower left corner of left atrium
3 Lower right corner of left atrium
4 Upper right corner of right atrium
Explanation:
A specialised cardiac musculature called the nodal tissue is also distributed in the heart. A patch of this tissue is present in the right upper corner of the right atrium called the sino-atrial node (SAN).

Statement A : Right and left atrium is separated by a thick muscular wall called inter-atrial septum. Statement B : Left and right ventricle is separated by a thin-walled inter-ventricular septum.
1 Statement A is correct but Statement B is incorrect.
2 Statement A is incorrect but Statement B is correct.
3 Both statements are correct.
4 Both Statements are incorrect.
Explanation:
Both the statements are incorrect. A thin, muscular wall called the interatrial septum separates the right and the left atria. a thickwalled, the inter-ventricular septum, separates the left and the right ventricles.
