3. Name the vein that drains blood from gall bladder directly into hepatic veins.
a) Gastric vein
b) Paraumbilical vein
c) Pancreaticoduodenal vein
d) Cystic vein

Explanation: Cystic vein drains the blood from the gall bladder and usually ends in the right branch of the portal vein.
4. How many hepatic veins are present?
a) 2
b) 3
c) 4
d) 1
View Answer
Explanation: There are 3 main hepatic veins which drain the hepatic parenchyma into inferior venacava. They have named the right hepatic vein middle hepatic vein and left hepatic vein,
5. Pulmonary vein carries ____________
a) Oxygenated blood
b) Deoxygenated blood
c) Mixed Blood
d) Blood with urea
View Answer
Explanation: While veins usually carry deoxygenated blood from tissues to heart in case of pulmonary vein it carries oxygenated blood. Oxygenated blood is carried from the lungs.
6. Pulmonary vein carries blood to _________
a) Right atrium
b) Left atrium
c) Aorta
d) Lungs
View Answer
Explanation: Pulmonary vein carries blood from lungs to heart. It drains into the left atrium.
7. What are the structures that keep blood flowing in unidirectional?
a) Bronchiole
b) Neuron
c) Septum
d) Valves
View Answer
Explanation: Valve normally allows blood to flow in only one direction. There are 4 valves in the human heart. A heart valve opens or closes on differential blood pressure on each side.
8. _______ circulation takes blood from heart to lungs and back.
a) Systemic
b) Body
c) Pulmonary
d) Blood
View Answer
Explanation: Pulmonary circulation is the process in which deoxygenated blood flows from the right ventricle to the lungs and returns oxygenated blood to the left atrium and ventricle of the heart.
9. ____________ returns blood from head, neck, thorax and upper limbs to right atrium.
a) Superior vena cava
b) Inferior vena cava
c) Pulmonary vein
d) Pulmonary artery
View Answer
Explanation: The Superior vena cava return deoxygenated blood from systemic circulation to the right atrium of the heart. It has a diameter of about 24mm.
10. Major superficial veins that empty into axillary veins drain superficial upper limb structure is ___________
a) Vena cava
b) Splenic vein
c) Femoral vein
d) Cephalic vein
View Answer
Explanation: Cephalic vein is a superficial vein in the arm. It is also known as the antecubital vein.
11. Vena cava is the largest veins.
a) True
b) False
View Answer
Explanation: Vena cava is the largest vein. Vena cava can be classified into superior vena cava and inferior vena cava.
12. Systemic venous system refers to the vein that drains into ________
a) Right ventricle
b) Right atrium
c) Left atrium
d) Left ventricle
View Answer
Explanation: Systemic venous system refers to the vein that drains into Right atrium without passing through two vascular beds.
13. Compared to artery, veins ____________
a) Have thinner walls
b) Hold their shape better when cut
c) Have pleated endothelium
d) Have smooth muscle in tunica media
View Answer
Explanation: As blood flowing through vein doesn’t have much pressure as in that of artery their walls are thinner as compared to the artery walls.
14. __________ circulation takes place from the heart to rest of the body.
a) Systemic
b) Full body
c) Pulmonary
d) Heart to lung
View Answer
Explanation: There are 2 types of circulation. They are pulmonary circulation and systemic circulation. Pulmonary circulation is between heart and lungs.
