Question

Name the following:
(a) A chordate animal having flame cells as excretory structures
(b) Cortical portions projecting between the medullary pyramids in the human kidney
(c) A loop of capillary running parallel to the Henle's loop.

Answer 1

a) Amphioxus is an example of a chordate that has flame cells as excretory structures. Flame cell is a type of excretory and osmoregulatory system.





(b) The cortical portions projecting between the medullary pyramids in the human kidney are the columns of Bertini. They represent the cortical tissues present within the medulla.

(c) A loop of capillary that runs parallel to Henle’s loop is known as vasa rectae. Vasa rectae, along with Henle’s loop, helps in maintaining a concentration gradient in the medullary interstitium.

Hope this will help you..... ✌

Answer 2

Dear Student,

● Answers -

(a) A chordate animal having flame cells as excretory structures

• Answer - Amphioxus

(b) Cortical portions projecting between the medullary pyramids in the human kidney

• Answer - Columns of Bertini

(c) A loop of capillary running parallel to the Henle's loop.

• Answer - Vasa recta

* Columns of Bertini help in anchoring of cortex to medulla.

* Vasa recta is osmotic exchanger in concentration of urine.

Best luck dear.
