GCSE Biology - How We Control Our Body Temperature #55

[@boedoedeedo]

This is one of the most criminally underrated channels on the internet, no matter what science concept I need to revise you explain it perfectly in only 5 minutes. Keep it up!

[@Cognitoedu]

🤩🤩 Thankyou!!

[@frejajacobsen4670]

These series must be so labor intensive to produce! Thank you so much for making them anyway. They’re really helpful and I hope it pays off for you to keep it running. One 4 minute video teaches me as much as an hour of my biology course. (I’m also learning English in these courses, so my language might be a bit flawed. Just wanted to say thanks)

[@Cognitoedu]

Hi Freja thank you for such a lovely comment! Yep they do take a while - but we’re really happy to see people are enjoying them and finding them helpful! Here’s hoping they continue to do well 🤞good luck with all your work!! :))

[@Dingdongbingaling]

Your English is exceptional 😃🥰❤

[@Guessy66666]

Your english is anything but flawed 😅

[@MisisEva]

This is the most useful and simple video I have found on the internet covering this topic. It definitely helped me with my homework. Thank you very much!

[@mauvieyy9083]

so underrated for someone who explains perfectly and just in 5-10 minutes ✨

Aw thanks Mauvieyy 😊

If you’d like to practise what's covered in this video, check out the lesson on the Cognito platform - cognitoedu.org/coursesubtopic/b2-gcse-aqa-h-t_7.02. The platform’s totally free, and has been built to make learning and revision as easy as possible. The main features are: - Lessons organised by topic, only the lessons relevant to your specific exam board and tier are shown. - Automatic progress tracking. Progress bars tell you what you’re doing well at, and what you need to spend some time on. - Practise quizzes so you can test your knowledge. You can quiz yourself on any combination of topics you like. - A huge number of fully-hinted questions that take you step-by-step through some of the trickiest calculations & concepts. - A comprehensive bank of past exam papers, organised both by year, and also by topic.

I really understand better than in class which is an hour. We talked with the teacher and now she shows us your videos from the projector before explaining us the topic.

Perfect pace to explain thermoregulation. Many thanks

[@scrat_xxx]

you deffo need more subscribers!! your vids are so frickin helpful

[@m3g4_154]

Summary of all you need to know: The thermoregulatory centre which is a part of the hypothalamus inside our brain acts as a thermostat for our body. To help it, we also have receptors throughout our body which are tiny things that detect a change in body temperature. Most of them are found in the skin and our blood vessels. By constantly sending information about our temperature to the thermoregulatory centre, the brain is able to figure out whether we are too hot or cold overall. If we are too hot, it will send us signals designed to cool us back down. If we are too cold it will bring about changes that warm us back up. In order to warm us up, we need to conserve the heat that we have and generate more. To conserve our heat, we constrict the blood vessels that lie near the surface of our skin (known as vasoconstriction). This means that less blood flows near the surface and less heat energy is lost to our surroundings. We also contract erector muscles which makes our hairs stand on end (this traps a small layer of insulating air, meaning its harder to lose heat from our skin - helps to keep us warm). To generate more body heat, we also shiver, where our muscles contract automatically, this requires a lot of energy from respiration. The chemical reactions involved result in a lot of heat energy released as moist which ends up warming us up. To cool us down, we do the opposite. The erector muscles relax allowing the hairs to fall flat. The blood vessels expand (vasodilate) allowing more heat energy to be transferred to our surroundings as lots of warm blood is passing close to the skins surface. We also produce sweat which is a mixture of water and salt that we release onto the surface of our skin. As the sweat evaporates, it takes heat energy from our body away with it as it requires a lot of energy to evaporate water - leaving us cooler.

[@supernovic99]

This was really helpful. All your videos are! Thanks a lot!

[@ernestpeace7980]

You deserve the best teaching award

[@thesavageanimator]

Hey, I think you might have made a small mistake. Erector muscles are different and are not used to cause goosebumps; instead, they maintain posture. You are talking about arrector pili muscles that attach to hair follicles. Thank You!
