Excretion and kidneys

By the end of this lesson you should be able to:

  • State that urea is formed in the liver from excess amino acids
  • State that carbon dioxide is excreted through the lungs
  • State that the kidneys excrete urea and excess water and salts
  •  Explain that the volume and concentration of urine produced is affected by water intake, temperature and exercise
  •  Identify on drawings, diagrams and images, the ureters, bladder and urethra
  • Explain the need for excretion, limited to toxicity of urea and carbon dioxide
  • Outline the structure of the kidney, limited to the cortex, medulla and ureter
  • Outline the structure and functioning of a kidney tubule, including:                                              -the role of the glomerulus in the filtration from the blood of water, glucose, urea and salts
  •         – the role of the tubule in the reabsorption of all of the glucose, most of the water and some salts back into the blood, leading to the concentration of urea in the urine as well as loss of excess water and salts (details of these processes are not required)

Activities

  1. Read pages 1 and 2 from this site. Pay attention to the different structures of the urinary system
  2. Play this animation. Follow instructions to understand how kidneys work
  3. What happens to the different substances along the kidney tubules. Click on them to find out!
  4. Complete the revision exercises given in class.

Enjoy! 🙂

Welcome Senior 4!

Hi everyone!

It’s our 2nd year in preparation for the IGCSE exam so one of our challenges will be about recycling what we studied in Senior 3. There are 3 main topics this year:

1- Human body
2- Plants
3- Living organisms and their environment

For each class you will be expected to bring last year textbook and the Booklet with exercises. Get your blog ready with the Biology category. All blog assignments should appear in the category and, as well as tests, will be posted in the class Calendar.

All the best for this year!

Welcome Senior 3!

Hi everyone!
Welcome to the S3 Biology course. This is the first year of a two-year preparation for IGCSE exam.

biologydiscoverlifebanner

The topics we will be studying are:

1- Characteristics and classification of living organisms.
2-Organisation of the organism
3- Movement in and out of cells
4- Biological molecules
5. Enzymes
6- Human nutrition
7- Transport in humans
8- Gas exchange in humans
9- Excretion and kidneys

10- Pathogens and immunity

As you see, you studied topics 1, 2 and 3 last year. Therefore, we are going to make a quick revision of them and continue with the new topics.

For each class you should bring the Biology coursebook. You are going to work a lot in your blogs, so add a category called “Biology”. All posts should be there.

Tests as well as blog assignments will be posted in the class Calendar.

Let´s start with a question…Why study Biology?

Study hard and enjoy!
