Life Functions #1
This keeps the body’s internal environment separate from the external environment.
What is maintenance of boundaries?
The ability of the body to react to stimuli.
What is responsiveness?
These give energy to our body cells.
What are nutrients?
The body’s ability to maintain stable internal conditions.
What is homeostasis?
Homeostasis is off balance; a disease or illness.
The production of offspring by uniting the sperm cell and the egg cell.
What is reproduction?
Examples of this are walking, dancing, writing, blood flowing, and uterus contracting.
This helps chemical reactions in our cells to release energy.
What is oxygen?
Communication within the body that contains three parts: receptor, control center, and effector.
What is the homeostatic control mechanism?
This part determines the level to be maintained in the body.
What is the control center?
This happens when the number of new cells increases faster than the number of dead cells.
What is growth?
All chemical reactions happening in the body.
What is metabolism?
Your breathing depends on this to inhale oxygen and exhale carbon dioxide.
What is atmospheric pressure?
A change (to the normal body function or feeling).
What is a stimulus?
This turns off the original stimulus or reduces its intensity, for example when you pull you hand out of a fire to reduce feeling heat.
What is negative feedback?
The tacos you have just eaten is broken down into simple molecules so your body can absorb and use the nutrients.
What is digestion?
Your skin would represent this function?
What is maintenance of bounderies?
This makes up 60% - 80% of our bodies and is the basis for all body fluids.
What is water?
This part is the response to the stimulus.
What is the effector?
This enhances the original stimulus and increases its intensity such as childbirth or a blood clot.
What is positive feedback?
Moving substances out of an area or out of the body.
What is excretion?
Urination and sweating examples of this function.
What is excretion?
When this is too high or too low, molecules and cells are destroyed or do not function properly causing all body activities to stop.
What is appropriate temperature?
This part receives information that senses a stimulus.
What is the receptor?
These represent nerves in the homeostatic control mechanism diagram?
