Questions and Answers

1.

During Pulmonary Circulation blood flows from lung to heart in which order?
- A.
  
  Right side of the lung , to left side of the heart
- B.
  
  Left side of the lung, to right side of the heart
- C.
  
  Right side of the heart, to left side of the lung
- D.
  
  None of the above
Correct Answer
A. Right side of the lung , to left side of the heart
2.

During Peripheal Circulation blood flows from the heart to the body and back to the heart in which order?
- A.
  
  right side of the heart, to the body, back to the heart
- B.
  
  Left side of the heart, to the body, back to the heart
- C.
  
  Neither
Correct Answer
B. Left side of the heart, to the body, back to the heart

Explanation
During peripheral circulation, blood flows from the left side of the heart to the body, delivering oxygen and nutrients to the tissues. It then returns to the heart through the veins, entering the right side of the heart. From there, it is pumped to the lungs for oxygenation before returning to the left side of the heart to start the cycle again. Therefore, the correct answer is "left side of the heart, to the body, back to the heart."

Keep blood moving in one direction
- A.
  
  Two semilunar valves
- B.
  
  Two atrioventricular valves
- C.
  
  Both
Correct Answer
A. Two semilunar valves

Explanation
The correct answer is two semilunar valves. These valves are located in the arteries leaving the heart (pulmonary artery and aorta) and their main function is to prevent blood from flowing back into the ventricles after it has been pumped out. They open when the ventricles contract and close when the ventricles relax, ensuring that blood flows in one direction only. The presence of two semilunar valves helps to maintain the proper circulation of blood throughout the body.

Atrioventricular valves
- A.
  
  Keep blood moving in one direction
- B.
  
  Separates atria from ventricles
- C.
  
  Both
Correct Answer
B. Separates atria from ventricles

Explanation
The correct answer is "separates atria from ventricles". Atrioventricular valves are located between the atria and ventricles in the heart. They serve to prevent the backflow of blood from the ventricles to the atria during ventricular contraction, ensuring that blood flows in one direction. Therefore, the atrioventricular valves separate the atria from the ventricles and play a crucial role in maintaining the unidirectional flow of blood through the heart.
