Question

Blood glands of Pheretima occur in segments

• A. 1, 2 and 3
• B. 3, 4 and 5
• C. 4, 5 and 6
• D. 10, 11 and 12

Answer 1

The correct option is C 4, 5 and 6

Blood glands are present on the 4th,5th and 6th segments. They produce blood cells and haemoglobin which is dissolved in blood plasma. Blood cells are phagocytic in nature. The blood vascular system of Pheretima is of closed type. It consists of the blood vessels, hearts, loops, capillaries, and the blood glands. Hence blood glands are present in 4th,5th and 6th segments.

So the correct answer is '4, 5 and 6'.
