Question

Malphigian capsules were named after Marcello Malphigi was born in
A. Germany
B. Italy
C. Australia
D. Austria

Answer 1

Hint: Marcello Malpighi was a biologist and a Physician. She was a founder of microscopical anatomy. She is known as the father of physiology and embryology. The name is born from the several secretory systems and amphibian corpuscles. Marcello Malpighi was born on 10th March 1628 and died on 29th November 1694.

Complete answer:
Marcello Malpighi was born in Italy. Carpascles was named after the 17th century. Excretion was performed by Malpighian tubules. Each tubule is lined by granular and ciliated cells. Granular and ciliated cells absorb nitrogenous waste products and convert them into uric acid which is excreted out through the hindgut. Therefore this insect is called uricotelic. In addition, the fat body, nephrocytes, and precise glands also help in excretion. Marcello Malpighi also tells about how the blood gets clotted against the least sides of the heart.

Hence, the correct answer is option (B).

Note: The process by which metabolic waste products are eliminated from the body of animals is called excrete. It is different from the question, which is the discharge of undigested food materials from the body. Nitrogenous wastes are the most important metabolic waste excreted by animals. At the junction of midgut and hindgut, there is a presence of a ring of yellow-colored thin filament called amphibian tubules. They help in the removal of excretory products. The hindgut is broader and is differentiated into ileum, colon, and rectum. The rectum opens to the anus.
