11.1 Antibody Production & Vaccination

BioKnowledgy Presentation on 11.1 antibody production and vaccination (AHL) from Chris Paine

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

BioKnowledgy Presentation on 11.2 movement (AHL) from Chris Paine.

Here is another presentation, taking you through muscle contraction step by step:


Two video lessons on 11.2 Movement: a 7m video from Luiz Mello and a 15m video from Briscucation.

A 5m TED-Ed intro to How the Muscular System works and from Crash Course, Muscles, part 1 – Muscle Cells: Crash Course A&P #21 in 10m and Muscles, part 2 – Organismal Level: Crash Course A&P #22 in 10m 40s.

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

BioKnowledgy Presentation on 11.3 The kidney and osmoregulation (AHL) from Chris Paine


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

Osmoregulator or Osmoconformer? Here are two videos about contractile vacuoles in Paramecium (they are osmoregulators): Paramecium vacuole (1m video) and contractile vacuole (a 27s explanation). If it goes wrong – Paramecium exploding!


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

A superb flash animation on the Kidneys from kscience.

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

BioKnowledgy presentation on 11.4 Sexual reproduction from Chris Paine

Paul Andersen describes The Reproductive System in 9m. 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.


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


Impressive Journey of Sperm – a 6m video on fertilisation.


Day 0 to 7 Fertilization, Zygote, Blastocyst 4m video from Armando Hasudungan. Implantation – a 2m 53s animation.
