What body system transports hormones produced by the endocrine system? (Hormones are transported in the blood stream)
Circulatory/Cardiovascular System
If your body cannot maintain homeostasis, what will happen to you?
Death
Which direction will water move across this semipermeable membrane?
To the right
To maintain homeostasis, what is the body's response to decreased blood oxygen?
Increased heartrate or breathing
What type of solution is this blood cell in?
hypotonic
What is the process where water passes through a semipermeable membrane from areas of high concentration to low concentration?
Osmosis
Which direction will water move in this picture?
Into the cell
What term describes the process of maintaining stability and balance?
Homeostasis
To maintain homeostasis, what is the body's response to increased water?
Remove water/pee
What is the process where molecules move from areas of high concentration to low concentration?
Diffusion
This graph shows blood glucose and insulin levels after drinking a glucose solution. Explain how this graph shows the body maintaining homeostasis.
To maintain a stable blood glucose level, the body produces insulin to remove excess glucose from the blood.
What is an example of negative feedback?
Maintaining body temperature, blood pressure, blood oxygen, blood glucose, or water
What type of solution is this cell in?
Hypertonic
Why can a freshwater fish not live in the ocean?
It's cells are designed to live in water with a lower salt concentration, if they are placed in salt water their cells will shrink and they will die.
What hormone is produced by the pancreas to help regulate blood sugar?
Insulin
This graph shows blood glucose and insulin levels after a person drinks a glucose solution. Explain how this shows the body is not maintaining homeostasis.
After the drink the blood glucose levels rise. The body needs to maintain constant blood glucose levels. This person is not producing insuliin.
What part of a cell controls what enters and leaves the cell?
Cell Membrane
What type of solution is this cell in?
Isotonic
What body system produces hormones like insulin?
Endocrine System
Explain how this graph showing a change in heart rate is evidence for our body maintaining homeostasis?
As the person exercises the heart rate increases to maintain a balance of oxygen in the blood.
What type of feedback loop is shown?
Negative Feedback Loop
If a cell has more water than it's surroundings, what will happen to the water?
It will leave the cell
To maintain homeostasis, what is the body's response to increase temperature?
sweating
What type of feedback loop causes your blood sugar to stabilize after eating a doughnut?
Negative Feedback
What condition does a person have when they cannot produce insulin or produce insulin that is ineffective?
diabetes
