If due to some injury the chordae tendinae of the bicuspid valve of the human heart is partially nonfunctional. What would be the immediate effect?
1 Heart beat would become irregular.
2 Blood will tend to move back into the right atrium.
3 The flow of blood into pulmonary artery will be reduced.
4 The flow of blood into the aorta will be slowed down.
Explanation:
A bicuspid or mitral valve guards the opening between the left atrium and the left ventricle. If due to some injury the chordae tendinae of the bicuspid valve of the human heart is partially non-functional then the flow of blood into the aorta will be slowed down.

'Bundle of His' is a part of which one of the following organs in humans?
1 Brain
2 Heart
3 Kidney
4 Pancreas
Explanation:
The bundle of His is an important part of the electrical conduction system of the heart. It transmits impulses from the atrioventricular node located at the ventricles of the heart.

Identify the valves which allow blood from ventricles into its respective blood vessels?
1 Aortic valve and mitral valve
2 Bicuspid valves and semilunar valves
3 Bicuspid and tricuspids valves
4 AV valves and semilunar valves
Explanation:
The openings of the right and the left ventricles into the pulmonary artery and the aorta respectively are provided with the semilunar valves. The valves in the heart allows the flow of blood only in one direction, i.e., from the atria to the ventricles and from the ventricles to the pulmonary artery or aorta. These valves prevent any backward flow. AV valves and semilunar valves allow blood from ventricles into its respective blood vessels.

'Brain of heart' is
1 SA node
2 AV node
3 Bundle of HIS
4 Purkinje fibres
Explanation:
Brain of heart is SA node. The SAN can generate the maximum number of action potentials, i.e., \(70-75 \mathrm{~min}^{-1}\), and is responsible for initiating and maintaining the rhythmic contractile activity of the heart. Therefore, it is called the pacemaker. Our heart normally beats 70-75 times in a minute (average 72 beats \({\rm{mi}}{{\rm{n}}^{{\rm{ - 1}}}}{\rm{)}}\).
