Homeostasis/Cells Review

Homeostasis

• allows for a wildly fluctuating internal environment

• is impossible in vertebrates

• is the maintenance of a relatively stable internal environment and often incorporates a form of feedback regulation

If the environment gets cold, we will often shiver in order to:

• keep body temperature the same as the external temperature
• decrease body temperature
• increase body temperature
• regulate blood pressure

Which of the following is NOT a system that helps regulate the blood sugar level?

• Circulatory system

• Muscle system

• Endocrine system

• Digestive system

Which hormone is released when blood sugar gets too high?

• glucose

• glucagon

• glycogen

• insulin

Which body system controls the body to maintain homeostasis?

• excretory

• nervous

• circulatory

• skeletal

a body system that controls growth and homeostasis by secreting hormones from glands.

• skeletal system
• nervous system
• endocrine sytem
• integumentary system

Name the levels of organization in the human body in order from smallest to largest:

• Tissue, organ, organ system
  
• Organ system, tissue, organs, cells
  
• Cells, tissue, organs, organ system
  
• Cells , organs, tissue, organ system

The "cause" for something to happen is the

• response
• effect
• stimulus
• homeostasis

With low oxygen levels, your breathing rate will increase. When your oxygen levels rise, what is the appropriate response?

• stop breathing

• increase heart rate

• keep breathing rate high

• return breathing rate to baseline

When your glucose levels are too high, what is the appropriate response?

• urinate

• release glucagon

• eat sugar

• release insulin
