Balancing Act
The processes by which your body maintains a stable internal environment.
What is homeostasis?
The control centre of the entire operation, and the most important nervous organ.
What is the brain?
If I start feeling hot, my skin effects a cooling response by excreting this substance.
What is sweat?
This system is responsible for defending the body from outside invaders.
The type of reproduction that produces genetically identical offspring.
What is asexual?
The type of feedback loop that restores balance.
What is negative?
The nervous system transmits this shocking type of signal to send messages throughout your body.
What are electrical impulses?
If I start feeling cold, my muscles effect a warming response by doing this.
What is shivering?
The scientific name for a foreign microorganism, such as a bacterium, virus, or fungus.
What is a pathogen?
The type of reproduction that requires two parents.
What is sexual?
The part of a feedback loop that detects a change in stimulus.
What is a sensor/receptor?
When you walk from a dark room into a bright room, the muscles in your eye cause this to happen to your pupil.
What is constrict/get smaller?
If someone looks pale and blue on a chilly winter day, this circulatory response is trying to keep their insides nice and toasty.
What is vasoconstriction (blood vessels in skin narrowing)?
The part of an intruder that your white blood cells can detect.
What are antigens?
An advantage of sexual reproduction.
What is genetic variation of offspring/increased adaptability to environmental changes?
Any organ or cell that ultimately responds to a stimulus.
What is an effector?
A reflex speedily bypasses normal nervous processes by communicating directly with this acting control centre.
What is the spinal cord?
If you get dehydrated, this organ holds onto more water and causes your urine to get darker.
What are the kidneys?
The proteins produced by white blood cells that bind to an intruder and mark it for destruction.
What are antibodies?
An advantage of asexual reproduction.
What is:
-requiring one parent?
-higher energy efficiency?
-faster production of offspring?
If I start exercising, my circulatory and respiratory systems increase the supply of oxygen to your muscles by doing this.
What is increasing heart rate and breathing rate?
This part of your brain is responsible for maintaining homeostasis by monitoring body temperature, controlling heart rate, triggering thirst response...what doesn't this workhorse do?!
What is the hypothalamus?
This endocrine gland is responsible for releasing insulin and glucagon, the key hormones involved in controlling blood glucose levels.
What is the pancreas?
This process trains the body using a weakened form of a bacterium or virus, leading to a faster response in future.
What is vaccination?
The female equivalent of testes.
What are ovaries?
