11.1 Antibody Production & Vaccination

Defense Against Infectious Disease (AHL) from Stephen Taylor – thank you Mr T (of iBiology) –  from the OLD syllabus, much is still relevant.

Fantastic animated tutorials from McGraw Hill Education – the Immune response, T-cell dependent antigens, Epitopes, antigen-presenting cells & T-helper cells, cytotoxic T-cells & monoclonal antibody selection.

Three videos from TED-Ed: how we conquered the deadly smallpox virus (well, if we ignore the work of the WHO); Learning from smallpox: how to eradicate a disease and here’s a simple answer to How do vaccines work?

11.2 Movement

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

This is an amazing gif from tabletop whale – you have to check it out:

An animated guide to the human body : The muscle edition

How do Nerves Carry Information? a 6m40s lesson from Naked Science Scrapbook.

Fantastic animated tutorials from McGraw Hill Education – Action Potentials & Muscle Contraction, Myofilament Contraction, sarcomere contraction & breakdown of ATP & cross-bridge movement.

Paul Andersen explains The Muscular System in 5m 59s.

In Crash Course Biology #30 The Skeletal System: It’s ALIVE!, Hank introduces us to the framework of our bodies, our skeleton and in #31 – Big Guns: The Muscular System, he tells us the story of the complicated chemical dance that allows our skeletal muscles to contract and relax.

11.3 The Kidney & Osmoregulation

A powerpoint of the OLD syllabus – much is still relevant though.

A nice introduction to how the kidneys work (from TED-Ed):

Mr Paul Andersen (from Bozeman High) describes Osmoregulation (including in fish which you don’t need to know) in a 8m 57s lesson.

An animated tutorial from McGraw Hill Education on basic Renal processes and here’s an animated, narrated tutorial on the mammalian kidney which also includes a quiz (from Sinauer Associates).

In Crash Course Biology #29 – The Excretory System: From Your Heart to the Toilet, Hank takes us on the fascinating journey through our excretory system to learn how our kidneys make pee.

11.4 Sexual Reproduction

6.6. & 11.4 Reproduction from Bob Smullen

A Biologist’s Mother’s Day Song (3m 50s):

Paul Andersen describes The Reproductive System in 9m.

Fantastic animated tutorials from McGraw Hill Education – spermatogenesis &  the  maturation of the oocyte & follicle.

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.
