Homeostasis

If hypothalmas did not respond to an increase in body temperature, the body might go into a state of shock and possibly suffer from heat stroke. This is because nothing would signal the body to release any hear, which would trap too much of it.

HOMEOSTASIS

-Homeostasis is the act of balencing substances - It is important because it helps keep everything in balance-Feedback mechanisms respond to imbalences and attempt to correct them in order to restore homeostasis

What is Homeostasis?

LESSON NUMBER

-Positive Feedback:*imbalence continues to increase like contractions during labor-Negative Feedback:*imbalence is corrected back to normal value *For example regulating body temperature *Sort of like a thermastat

NEGATIVE vS. POSITIVE FEEDBACK

-Kidneys maintain homeostasis by regulating substances such as water, salt, and wastes in the blood stream.-The glomerulus is actually responsible for filtering the blood in the kidney.

KIDNEYS

IMBALENCES

HOMEOSTAICIMBALENCE

-Homeostasis imbalence is the inability to maintain homeostasis and can result in disease and even death-Example: Kidney failure, diabetes, and dehydration

URINALYSIS

-A urinalysis can determine whether an indiviudal has a homeostatic imbalence by determining pH, specific gravity, glucose, protiens, bilirubin, ketones, presence of blood, nitrites, urobilinogen, and leukocytes.-A urinalysis can diagnose liver disease, kidney stones and diabetes.

DIAGNOSTIC TESTS

-Diagnostic tests are able to determine wheter an individual has a homeostatic imbalence by checking vital signs and taking blood tests in order to determine if tissues, organs and systems are functioning correctly.-Example: If the pulse of a normal adult was 20 beats per minute the adult will have a homeostatic imbalence, which may result in low blood pressure.
