Biology
Alas , my favourite science. This page is mostly breaking down key notes as I'm studying biology at the moment and absolutely love it so sharing some of what I'm learning may be useful to you awesome li'l people on my screen :)
The human nervous system
Principles of homeostasis
Homeostasis - The regulations of internal conditions within a
( Balancing ) cell/organism to maintain optimum condition
It does this because humans and other animals organs cannot function if the
internal environment is changing.A more in depth description of the internal environment:
.The conditions inside our body that self regulate are due to homeostasis
.Enzymes , which work at their best in specific temperatures or Ph levels
-Enzymes control all the functions of a cell
.Cells are key components to the function of tissues , organs and whole organisms
-Elements of our internal environments
Internal conditions controlled by homeostasis:
.Body temperature
.Blood Glucose levels
.Water levels
Coordination and control
Organisms (animals and plants) need to be aware of changes around the e.g. changes in temperature or levels of sunlight.
- Organisms need to respond to these changes in their internal environment .
