Temperature Control
Body temperature balance is maintained through this type of feedback loop.
What is negative feedback?
This system helps maintain a stable internal environment.
This rigid layer maintains plant cell shape and prevents rupture.
What is Cell Wall?
A mechanism triggered when blood volume is low and solute concentration is high.
What is Thirst Mechanism?
This process helps maintain body temperature through shivering.
What is muscle contraction?
The body's thermoregulatory set point is maintained at approximately this temperature.
What is 98.6°F (37°C)?
This solution has equal solute concentrations inside and outside the cell.
What is Isotonic?
Organs filtering waste and excess fluids from blood.
What are the kidneys?
This organ acts as the body's thermostat to regulate temperature.
What is the hypothalamus (part of the brain)?
Anhidrosis is example of the body's inability to sweat/perspire. This condition interferes with this process.
What is thermoregulation?
Solute concentration is lower outside the cell in this type of solution.
What is Hypotonic?
This hormone regulates water reabsorption in the kidneys.
What is Antidiuretic Hormone (ADH)?
Dilation of these blood vessels allows more blood to flow to the skin, releasing heat.
What are capillaries?
Blood clotting is an example of this mechanism.
What is positive feedback?
This type of solution causes cells to shrink due to water loss.
What is Hypertonic?
Waste substance transported from liver to kidneys via bloodstream for removal.
What is Urea?
These body systems work together to warm the body up.
Nervous, circulatory and muscular system.
What is negative feedback?
Freshwater fish in saltwater experience this due to excessive salt.
What is Dehydration?
Kidneys respond to low blood volume by releasing this electrolyte/ion.
What is Sodium?
