Question

Location of Malpighian tubules in Periplaneta:

• A. Foregut - Hindgut
• B. Midgut - Foregut
• C. Hindgut - Midgut
• D. Stomodeum - Proctodeum

Hint:

In studying insect physiology, noting the location and function of Malpighian tubules can provide insights into how insects maintain ionic and water balance, crucial for their survival in diverse environments.

Answer 1

The Correct Option is C

Understanding the anatomy of Periplaneta.
Malpighian tubules are specialized structures in insects that serve as the primary site of waste excretion and osmoregulation. In Periplaneta (the common cockroach), these tubules are strategically located at the junction of the midgut and hindgut. This placement allows them to efficiently filter out waste from the hemolymph (insect blood) as it circulates through these regions.
