11.2 Movement

11.2 Movement from Bob Smullen

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

11.3 kidney from Bob Smullen

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):

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

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.
