Solution
The correct option is A Nephrocytes
Nephrocytes, uricose glands, malpighian tubules, fat body, etc. are parts of a cockroach's excretory system.
The nephrocytes are arranged on each side of the heart and hence are also known as pericardial cells. They are considered to be excretory in function.
Uricose glands are long tubules of utricular gland of the male cockroach. These tubules store uric acid and discharge it over the spermatophore during copulation.
Malpighian tubules are yellow colored, long and unbranched blind tubules attached at the midgut and hindgut junction. They extract metabolic waste from the blood.
The fat body consists of fat cells and lies below the body wall filling most of its space. Some fat cells get excretory matter from the blood.
