Homeostasis
The ability of an organism to maintain a stable internal environment.
homeostasis
An important protein and hormone in the regulation of blood glucose
insulin
The two types of feedback loops
Positive and Negative Feedback
Is compose of glands that secret different hormones.
Endocrine system
The basic unit of the nervous system.
Nerve cell or neuron
What disrupts homeostasis?
disease or illness
Lack of insulin which causes elevated glucose levels in the bloodstream
diabetes
An INCREASE in one action causes an INCREASE in another
positive feedback
a gland located below the voice box that regulates body metalism
Thyroid gland
Give the the 3 basic parts of neuron
axon, cell body, dendrites
Give 2 aspects of the body that must be maintained in order to achieve homeostasis.
pH, Body Temperature, and Blood Sugar....
a gland that produces insulin in order to regulate blood glucose level in the body
pancreas (beta cells)
2 examples of negative feedback
Thermoregulation
Blood sugar regulation
The gland that enables the body to produce antibodies
Thymus
The thermoregulating center of the brain
hypothalamus
What is the balanced level of body Temperature?
Body Temperature-37 degrees Celsius
The hormone produce by the pancreas that used to breakdown glycogen into its simplest form.
glucagon
Most common feedback in the body and nature
negative feedback
Give the 2 hormones produce by the ovary
estrogen and progesterone
Enumerate the 5 sense organs that assist the nervous system in interpreting stimuli.
eyes, ears, nose, tongue, and skin
This occurs when homeostasis is not achieved ...
death!
What is negative feedback?
A mechanism that occurs when the body systems need to slow or stop a process that is occuring.
How is the body responding to try and return back to its balanced and stable state?
One of the most easily noticeable is temperature. When your body gets too hot, you release sweat, which cools you down. When you get too cold, your body tenses up hair muscles on your arms to generate heat.
Blood sugar regulation
Explain the function of ovary
produce the hormones estrogen and progesterone necessary in reproduction
Discuss the participation of the nervous sys. in the homeostatic system
it interprets nerve impulses carried by the nerve cells
