Misc. Homeostasis
Which body system takes in information and sends signals throughout the body?
Nervous system
This molecule is broken down during cellular respiration to produce energy.
Glucose
This hormone lowers glucose levels in the blood by moving the glucose into cells for respiration or storage.
Insulin
This word describes a condition where the body's core temperature drops below the set point.
Hypothermia
This solute is completely removed from the body by the kidneys.
Urea
This type of feedback mechanism occurs when a response counteracts a stimulus.
Negative feedback
These two molecules are the byproducts of cellular respiration.
Carbon dioxide and water
This condition results from a person's inability to produce enough of or any insulin.
Diabetes
This body system is responsible for producing shivering as a response to a drop in core body temperature.
Muscular system
This word describes the movement of water across a membrane.
Osmosis
This organ produces antidiuretic hormone (ADH).
The brain
This plant structure allows for the release of oxygen and the absorption of carbon dioxide.
Stomata
How does exercise affect blood glucose levels?
Exercise lowers blood glucose levels.
What type of feedback mechanism regulates body temperature when a person is too hot?
Negative feedback
Illustrate a blood cell in a hypotonic solution.
Water only moving into the cell, cell swollen.
What happens to the circulatory system during the mammalian dive response?
Heart rate decreases to conserve oxygen.
This is the part of the cell where anaerobic cellular respiration takes place.
Cytoplasm
How will the pancreas respond to a decrease in blood glucose levels?
By decreasing the release of insulin and increasing the release of glucagon.
What role does the nervous system play in regulating body temperature?
The nervous system senses changes in body temperature and sends signals to generate responses.
How does antidiuretic hormone (ADH) affect the composition of the urine produced by the kidneys?
ADH conserves water, making the urine more concentrated (less water).
How do the cells inside of a saltwater fish compare to their surrounding environment?
They are hypotonic to their surrounding environment.
This vessel transports blood with a low concentration of oxygen.
Vein
How is blood glucose regulated by a feedback loop?
When blood glucose goes down the pancreas releases glucagon, when blood glucose goes up the pancreas releases insulin.
How will capillaries in the body respond when the core body temperature rises past the set point?
By dilating (becoming wider) to release more heat.
How do the kidneys increase the amount of water that is reabsorbed into the bloodstream?
By releasing enzymes that pump sodium into the bloodstream, which is then followed by water.
