Explain the relationship of homeostasis to body fluids? - ANSWERS Regulates
balance of water and electrolytes, blood , serum, albumin urine, bile , hormones,
CSF, these fluids are critical to maintain homeostasis
A state of equilibrium in the internal environment of the body, naturally
maintained by adaptive responses that promote healthy survival. - ANSWERS
homeostasis
1.A Medium for metabolic reactions within cells
2. Transporter for nutrients and waste products
3. Lubricant for joints and membranes
4. Shock absorber
5. One means of regulating and maintaining body temperatures
6. Insulator - ANSWERS waters functions
Concept of fluid/ electrolytes ? - ANSWERS process that regulates the balance
of water & electrolytes & conditions that contribute to imbalances
Blood pressure & maintaining temperature are examples of what type of
feedback? - ANSWERS negative feedback
,Blood clotting & women in labor are examples of what type of feedback? -
ANSWERS positive
