Which side of the heart is involved in pulmonary circulation?
(1) left side
(2) right side
(3) partially left side and completely right side
(4) both side equally
Which vessels bring blood to right atrium?
(1) Vena Cava and coronary sinus
(2) Pulmonary veins
(3) Pulmonary artery
(4) Aorta and pulmonary artery
Human Heart has SA node which makes it–
(1) myogenic heart
(2) neurogenic heart
(3) Digenic Heart
(4) Rhinogenic Heart
The neurocenter for the activity of the Heart is located in
1. Pons
2. midbrain
3. medulla oblangata
4. cerebrum
Medulla Oblangata regulates the Cardiac activity via
(1) CNS
(2) ANS
(3) PNS
(4) CNS and PNS
The sympathetic nerves give _______ neural signals to heart and increases the _______.
(1) stimulatory, ventricular contraction
(2) inhibitory, stroke volume
(3) stimulatory, ventricular relaxation
(4) inhibitory, ventricular relaxation
If the strength of ventricular contraction increases then it will cause
(1) increase in Heart beat rate
(2) increase in cardiac output
(3) reduced supply of oxygen
(4) both (1) and (2)
What is the effect of parasympathetic neural signals on Heart Activity?
1. decreases the rate of heart beat
2. decreases the speed of conduction of action potential
3. decreases the cardiac output
4. all of these
Arteries have ________ layer of smooth muscles than ________
(1) thicker, vein
(2) thicker, aorta
(3) thinner, vein
(4) thinner, aorta
The hormonal regulation of Cardiac output is
(1) mediated by adrenal cortex
(2) mediated by adrenal medulla
(3) mediated by thyroid
(4) mediated by pineal
