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.

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

11.3 The Kidney & Osmoregulation

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

OSMOREGULATION

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!

THE KIDNEYS

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.

GAMETOGENESIS

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

FERTILISATION

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

IMPLANTATION & EMBRYO DEVELOPMENT

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

6.6 Hormones, Homeostasis & Reproduction

BioKnowledgy presentation on 6.6 hormones homeostasis and reproduction from Chris Paine

6.6 Hormones, Homeo & Repro notes to complete (created by Mrs Green).

IB Biology 6.6 notes – Cheryl Haus talks us through the topic while making notes in a 1 hour video.

Some past paper questions answered by IB Blueprint: Nerves, hormones and homeostasis – Paper 1 Questions ; Nerves, hormones and homeostasis – Paper 2Reproduction – Paper 1 QuestionsReproduction – Paper 2 Questions.

HORMONES

Crash Course Biology #33: Great Glands – Your Endocrine System (11m). Hank also does Endocrine System, part 1 – Glands & Hormones (Crash Course A&P #23) in 10m 24s and part 2, Hormone Cascades (Crash Course A&P #24) in 9m 33s.

The Endocrine system explained in under 4 minutes – a nice introductory video – or here is a 5m video The Endocrine System in more detail than you need or Mr Andersesn’s The Endocrine System in 13m 47s.

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).

HOMEOSTASIS & NEGATIVE FEEDBACK

Positive & negative feedback loops, a 14m video lesson from Mr Andersen, who also teaches us elements of a feedback loop in 9 minutes.

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):

THE MENSTRUAL CYCLE & HORMONES

How menstruation works and Why do women have periods? – 2 videos from TEDEd.

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.
