  • 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
