IGCSE Bio Topic 11 – Gas Exchange in Humans

Topic 11 revision notes in downloadable word format.

Lessons from Ms Cooper: the Human Respiratory System in 9m; breathing rate and depth of breathing in 7m 40s; properties of the gaseous exchange system in 8m 40s.

Science Bank 22 (Body Parts): you just need Part 1 – The Lungs (to 5m 20s):

How do the Lungs work? – a three and a half minute TED-Ed lesson:

And here is another TED-Ed lesson in 5 m: Oxygen’s surprisingly complex journey through your body.

Gas Exchange – a 3m video on oxygen transport from lungs to cells. The Respiratory System – a 3m 30s video on how the respiratory system works. The Virtual Body – Circulation, Respiration & Breathing (a 19m video).

B6 Respiration (Combined Science)

For self-assessment questions, with exercises and discussions, just click on the correct topic at Biology GCSE & IGCSE Question Bank. A powerpoint can be downloaded from the same site here. The s-cool revision site lets you revise the topic, summarizes the topic & tests you on it. Skoool gives you a lesson, including progress questions, for each Biology topic but you’ll need sound on for it. GCSE Bitesize has revision pages (that take you through the topic), a test and an activity.

B6.1 RESPIRATION & ENERGY

What is aerobic respiration? a short (51s) introductory video from Clipbank.

Science Bank 8 (Biological Reactions): you only need Part 2 – Respiration (from 5m 20s to 9m 55s) and you only need to know about aerobic respiration:

B6.2 GAS EXCHANGE

Science Bank 22 (Body Parts): you just need Part 1 – The Lungs (to 5m 20s):
