Homeostasis Review

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

What are the different ways in which the body loses heat?

• Compression, expansion, and condensation

• Insulation, absorption, and reflection

• Ingestion, digestion, and excretion

• Radiation, conduction, convection, and evaporation

Which part of the brain is responsible for regulating body temperature?

• Occipital lobe

• Cerebellum

• Frontal lobe

• Hypothalamus

How does the body respond to low temperatures in order to maintain homeostasis?

• Dilating blood vessels, sweating, and decreasing metabolic rate

• Relaxing muscles, increasing blood flow, and decreasing heart rate

• Expanding blood vessels, panting, and decreasing shivering

• Constricting blood vessels, shivering, and increasing metabolic rate

How does the body respond to high temperatures in order to maintain homeostasis?

• By increasing sweat production, dilating blood vessels near the skin's surface, and increasing breathing rate.

• By increasing body temperature even further

• By decreasing breathing rate and shivering

• By decreasing sweat production and constricting blood vessels near the skin's surface

what is osmoregulation?

• Control of water and salt in the body

• Control of blood pressure in the body

• Control of blood glucose in the body

Which area of the brain contains the receptors responsible for detecting changes in water potential

• Hypothalamus

• Medulla Oblongata

• Amygdala

• Hippocampus

This graph shows an example of...

• Blood sugar regulation

• Homeostasis

• Negative feedback

• Positive feedback

Which hormone promotes retention of water by kidneys?

• epinephrine/norepinephrine

• antidiuretic hormone

• glucagon

• prolactin

Since alcohol consumption blocks the production of antidiuretic hormone, what is most likely to happen?

• The pain caused by internal and external factor will decrease in intensity

• You will feel the urge to sleep.

• There will be an increase in urine production.

• There will be a decrease in urine production.
