Q. No.
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) 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
The normal blood pressure is-------- and if it gets increased, such disorder is called---------
(1) 120/80; hypertension
(2) 80/120; blood tension
(3) 120/80; high blood pressure
(4) both 1 and 3
The pumping pressure is also known as------- and the resting pressure is also known as------
(1) systolic pressure, diastolic pressure
(2) diastolic pressure, systolic pressure
(3) normal pressure, abnormal pressure
(4) abnormal pressure, normal pressure
