Describe the Structure of Nephron
Structure of Nephron
Nephron is structural and functional unit of kidney and excretory system. Each nephron consists of two parts:
Renal Corguscle:
Renal corpuscle is further divided into two parts:
- i) Glomerulus is a group of capillaries. Blood enter in them through renal artery.
- ii) Bowman’s capsule is a cup shaped blind end of the nephron. It surrounds glomerulus from all sides.
Renal Tubule:
It is long and narrow tube and has three parts:
- i) 1st coiled part is first portion of nephron. It twisted upon itself in very complex way.
- ii) Loop of Henle is second part of nephron, which is U-shaped tube.
iii) Last coiled part is last portion. It is also coiled. These coiled parts open into larger duct called collecting duct. These collecting ducts collects urine from nephrons and pour it into renal pelvis.
Note: After learning the words and examples, repeat everything you learned before going to bed. Then try to remember what you learned in the morning. Try to use the already learned words in the exercises, in writing and in oral speech. Make up examples with new words, combining those that you see for the first time and those that have already learned. A good dictionary is one of the most important books that a student should have. A good dictionary gives pronunciation, several meanings, Example of use, synonyms and antonyms. A good dictionary in pictures is a very useful additional tool that will help you understand and remember words without having to translate them. There are many good dictionaries, textbooks and Internet resources that can be very useful in learning English vocabulary.
