Transport Systems in Living Things

Test Yourself: What are the functions of red blood cells, white blood cells, platelets, and plasma?

How are they adapted to carry out their functions effectively? 

Test Yourself: What are the functions of the arteries, veins and capillaries?

How are they different?
(e.g. blood pressure, their wall structure, and the substances they transport) 

Test Yourself:

1. What does the term 'diffusion' and 'osmosis' mean?

2. Can you explain how diffusion helps to transport substances in humans / plants? (Link this to the absorption of nutrients in small intestine)

3. Can you explain how osmosis helps in the absorption of water at the roots?

Think: What gases diffuse in and out of the stomata? 

Test Yourself: What are the functions of the xylem and the phloem?

How are they adapted to carry out their functions well? 

Tip: This procedure investigates whether the xylem transports water 

Think: Most people would have taken a pill, received an injection, or otherwise took some kind of medication during their lives.

But most of us might not be aware of how these substances actually work.

Learn how certain drugs could have detrimental effects on many systems in our body, impacting the way we physically feel, think, and even behave.

Think: What is organ transplant?

What are some ethical issues relating to heart transplant? (e.g. donor consent, or priority for allocation)

Tip: The effects of drug abuse during pregnancy can be extremely harmful to the welfare of babies
