The hepatic portal system is

(1) Between digestive tract and hypothalamus

(2) Between digestive tract and liver

(3) Between liver and hypothalamus

(4) Between liver and Pituitary

The hepatic portal ________ carries blood from ________ to liver before it is delivered to the ________.

(1) vein, Pancreas, Pulmonary

(2) artery, intestine, systemic

(3) vein, intestine, systemic

(4) artery, Pancreas, Pulmonary

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
