Homeostasis, the Endocrine System, and stuff.

Homeostasis involves all organ systems interacting to maintain internal stability.

• true
• false

The interacting body systems are controlled and regulated by which two systems?

• integumentary system and endocrine system
• nervous system and skeletal system
• nervous system and endocrine system
• muscular system and digestive system

the feedback mechanisms regulated by the nervous system are slower than those regulated by the endocrine system

• true
• false

Automatic responses by the body to internal or external stimuli that threaten homeostasis are known as 

• the islets of langerhans
• the pituitary gland
• the master gland
• feedback mechanisms

When a person is exercising on a hot day, he or she sweats, helping to maintain homeostatic body temperature. This is an example of:

• organ system malfunction
• feedback
• fighting infection
• a disruption of homeostasis

Protein structures on cell membranes that fit with hormones like a lock and key, allowing the cell to receive a chemical message are known as:

• catalysts
• enzymes
• antibodies
• receptors

When the adrenal gland secretes it's product, adrenaline, the body is preparing for a "fight or flight" response. The target cells (which have the properly shaped receptors) for this hormone are located in which organ?

• the brain
• the liver
• The heart
• the kidneys

Which type of diabetes develops suddenly, at a young age?

• type I
• type II
• type III

The opposing actions of the hormones insulin and glucagon help, in a healthy person, keep blood glucose within a range of 65 mg/dL and 140 mg/dl. This is an example of

• A feedback mechanism
• a disruption of homeostasis.

The opposing actions of the hormones insulin and glucagon help, in a healthy person, keep blood glucose within a range of 65 mg/dL and 140 mg/dl. This range means that blood glucose should never get too high or low, and is an example of:

• Feeding positivity
• Positive feedback
• Equal dynamism
• Dynamic equillibrium
