This set of Human Anatomy Interview Questions and Answers for Experienced people focuses on “Portal System, Pulmonary & Systemic Veins”.
1. Portal system includes vein which drains blood from _______
a) Head and neck
c) Abdominal part
Explanation: Portal system includes vein which drains blood from abdominal part of digestive tube, spleen, pancreas and gall bladder. The exception is a rectum. It is about 8cm long.
2. Portal circulation ends in __________
Explanation: Portal circulation begins in capillary plexuses and ends in liver sinusoids.
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?
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
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
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?
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.
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
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
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.
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
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
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.
b) Full body
d) Heart to lung
Explanation: There are 2 types of circulation. They are pulmonary circulation and systemic circulation. Pulmonary circulation is between heart and lungs.
