In which organ is the enzyme trypsin important?
Mouth
Stomach
Large intestine
Oesophagus
The Correct Answer is B
A. Mouth: Digestion in the mouth is primarily due to amylase, which breaks down carbohydrates, not trypsin.
B. Stomach: Trypsin is produced as trypsinogen in the pancreas and is activated in the small intestine. While trypsin is crucial for digestion, it is important in the small intestine.
C. Large intestine: The large intestine is mainly involved in water absorption, not digestion by enzymes like trypsin.
D. Oesophagus: The esophagus transports food but does not produce enzymes like trypsin.

Correct Answer is C
Explanation
A. Increased afterload: Increased afterload, the resistance the heart must overcome to eject blood, typically reduces stroke volume because the heart has to work harder to push blood against higher pressure.
B. Decreased heart contractility: This would reduce stroke volume, as the heart would be less effective at pumping blood.
C. Increased preload: Preload refers to the volume of blood in the ventricles at the end of diastole. An increased preload stretches the heart muscle, which typically leads to a stronger contraction and higher stroke volume.
D. Decreased blood pressure: While low blood pressure may reduce afterload, it doesn't directly increase stroke volume unless other factors are at play.
Correct Answer is D
Explanation
A. Seminal duct: There is no structure specifically called the "seminal duct" in male anatomy.
B. Epididymis: The epididymis is the tube where sperm mature, and it connects to the ductus deferens, not the urethra.
C. Prostatic duct: Prostatic ducts release prostatic fluid into the urethra, but they do not connect the ductus deferens to the urethra.
D. Ejaculatory duct: The ejaculatory duct connects the ductus deferens to the urethra, allowing sperm to enter the urethra for ejaculation.
