6.1 Digestion & Absorption

A powerpoint from the OLD syllabus, but much is still relevant.

A fantastic animated tutorial from McGraw Hill Education on the Organs of Digestion & one on the action of Sucrase.

Mr Paul Andersen (from Bozeman High) details The Digestive System in a 9m 38s tutorial:

In Crash Course Biology #28 – The Digestive System, Hank takes us through the bowels of the human digestive system and explains why it’s all about surface area.

6.2 The Blood System

A powerpoint from the OLD syllabus; much is still relevant.

A fantastic animated tutorial from McGraw Hill Education on the cardiac cycle.and here’s an animated, narrated tutorial on blood flow through the human heart (from Sinauer Associates).

Paul Andersen surveys The Circulatory System in humans in an 11m 35s tutorial.

In Crash Course Biology #27 – Circulatory & Respiratory Systems, Hank takes us on a trip around the body – we follow the circulatory and respiratory systems.

6.3 Defence against Infectious Disease

Thanks to Mr Taylor (of iBiology) for the powerpoint – from the OLD syllabus but some great stuff.

Fantastic animated tutorials from McGraw Hill Education – HIV replication (how a retrovirus replicates) & how the HIV infection cycle works – and an animated, narrated tutorial on the life cycle of HIV which also includes a quiz (from Sinauer Associates). All in more detail than we need. Why it’s so hard to cure HIV/AIDS (a TED-Ed lesson).

Mr W sings I’m a Virus!:

In Crash Course Biology #32 – Your Immune System: Natural Born Killer, Hank tells us about the team of deadly ninja assassins that is tasked with protecting our bodies from all the bad guys that want to kill us – also known as our immune system.

6.4 Gas Exchange

A powerpoint from the OLD syllabus, much is still relevant.

Fantastic animated tutorials from McGraw Hill Education – alveolar pressure changes during breathing & gas exchange during respiration (breathing).

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

Paul Andersen describes The Respiratory System in an 8m 46s tutorial.

In Crash Course Biology #27 – Circulatory & Respiratory Systems, Hank takes us on a trip around the body – we follow the circulatory and respiratory systems.

6.5 Neurons & Synapses

Thanks again Mr Taylor (of iBiology) for this powerpoint from the OLD syllabus. 

From Sinauer Associates we have an animated, narrated tutorial on Reflex Arcs which also includes a quiz and here are animated, narrated tutorials on the synapse and action potentials.

Click on ‘Signal Transduction’ to see an Interactive Animation from Wiley on how hormones work & Cholera (& lots more that you don’t need to know).

An animated tutorial from McGraw Hill Education on blood sugar regulation in diabetics. and here is ‘What does the Pancreas do?’ (from Emma Bryce & TED-Ed):

In Crash Course Biology #26 – The Nervous System, Hank begins a series of videos on organ systems with a look at the nervous system and all of the things that it is responsible for in the body. In #33 – Great Glands: Your Endocrine System, Hank fills us in on the endocrine system.

6.6 Hormones, Homeostasis & Reproduction

CONTENT TO BE ADDED HERE (at some point).

Thank you Mr Taylor (of iBiology) for this presentation from the OLD syllabus.

Animated, narrated tutorials on the menstrual cycle and on pregnancy testing which also include a quiz (from Sinauer Associates); there’s also an animated, narrated tutorial on IVF.

In Crash Course Biology #34 – The Reproductive System: How Gonads Go, Hank lets us in on the meaning of life, at least from a biological perspective – it’s reproduction.

The physics of sperm vs. the physics of sperm whales from TED-Ed.
