Urine formation by the nephrons in the kidney

Hi,

This is a short but crisp video on how urine is formed from the blood at the millions of tiny nephrons found in the kidneys. The involvement of the glomerulus, proximal and distal tubules, the loop of Henle and processes such as ultra-filtration and active transport are explained.

Lesson 32: Kidney-an excretory organ

This is not in the syllabus for the Science Biology students but you are welcome to go beyond that. Of course the Pure Biology students know that Kidney and its excretory functions are an important part of their syllabus.
This set of powerpoints slides are very good in enhancing your understanding of this topic. It covers details of the following:

• definition of the term excretion
• urinary system, annotated diagram
  
• kidney, L.S., annotated diagram
  
• nephron, annotated diagram
• step by step, urine formation, annotated
• quiz
