Homeostasis: How Your Body Stays in Balance with its Environment

- MEDICAL ANIMATION TRANSCRIPT: All structures in the body function together to maintain homeostasis, a process by which the body maintains its internal environment in response to the external environment. Examples of how the body maintains homeostasis include metabolism of drugs and toxins in the liver, regulation of water and solutes in the blood by the kidneys, regulation of blood glucose by the pancreas. Another homeostatic process, thermal regulation, is the maintenance of normal body temperature. If the body's skin or core temperature drops, thermoreceptors in the skin or internal organs send impulses to the hypothalamus, which acts as the body's thermostat. The hypothalamus responds through the sympathetic nervous system by constricting blood vessels in the skin. Vasoconstriction diverts blood away from the skin and extremities to the warmer interior of the body to prevent further loss of heat to the surroundings and prevent the body's core temperature from dropping further. Arrector pili muscles contract, causing piloerections in which hair follicles stand up in an attempt to trap warm air next to the skin. A continued drop in temperature prompts the hypothalamus to send impulses that elicit a shivering reflex in skeletal muscles, generating additional heat to increase body temperature. If the body's skin or core temperature increases, thermoreceptors in the skin or internal organs prompt the hypothalamus to halt sympathetic stimulation of blood vessels in the skin. The vessels dilate and allow warm blood to distribute heat through the skin. Arrector pili muscles relax and hair follicles lie flat against the skin. Sweat glands produce sweat, allowing heat loss through evaporation. The stimulus or decrease in body temperature causes the brain to act as a thermostat and dissipate heat throughout the body. Once normal temperature is reached, the thermostat shuts off. These examples of the body's response to counteract stimuli are called negative feedback loops, which allows the body to maintain homeostasis.

Watch it at 1.5x speed, it's way too slow on 1x
I watched it 2× the speed
Thank you much helped
Hey,I love it that way
i fall asleep watching these, its perfect for my use xD
How about 4x
Hi please make videos on following topics
Glycolysis
Link reaction kreb cycle
Photosynthesis
Homeostasis in humans in kidneys
Homeostasis in plants stomata
Action potential
Selective reabsorption etc
Amazing…. Maa shaa Allah
God's work 💙 🙏🏻
Mom’s and dad’s work 😏
Yes, you'd have to be a fool to say there isn't a God when studying the biology and seeing how highly organized living things are.
Its 20°F outside and I'm just in a T-shirt and shorts. I feel fine. No coldness or shivering.
The Body. An amazing machine.
Amazing study minutes these for me and all viewers😊
Brilliant representation ❤
The work of Gods hands.
Nice
It's very good for me to understand.
I was forced to watch this for class 😭
❤❤❤❤❤❤
❤❤
how can I design an animation video like this , please some one help me
can you believe there are people who still think that all of this (Balance, Equilibrium and Perfection in our bodies and the whole universe) was made by chance and random particles interacting with each other...
i'm so sad for those people and wish Allah one day show them the right way.
There are too many imperfections. It is still surprising people choose to believe things said by ancestors 1000s of years ago. If any of those great God men and creators of religion were alive and said the same things today, you will be calling them crazy.
Billions of years of evolution perfected the human body but there still imperfections

Hold your finger down to speed the video 2x
🥰🥰🥰🥰🥰🥰😍😍😍
