Test in Ten: Homeostatic temperature regulation

One of the most common examples of homeostasis is body temperature. When your body temperature rises above normal, how does your body respond?

• shivers

• sweats

• coughs

There were many systems involved in helping the body keeps its normal body temperature. Check all that apply.

• Nervous

• Circulatory

• Muscular

• Integumentary

Why does pulse rate increase during exercise?

• Oxygen and carbon dioxide must be removed from the body ASAP

• Gas exchange must happen more quickly than when a person is at rest

• Oxygen must be moved to the lungs and carbon dioxide must be moved to cells more quickly

• Carbon dioxide must be moved to the kidneys to be excreted

What is the evaporation of a liquid to cool the body?

• Shivering
• Sweating
• Vasodilation
• Vasoconstriction

A student walks into a cold room.

Which of the following happens to his body?

• Sweating and vasodilation of blood vessels.

• Shivering and vasoconstriction of blood vessels

• Sweating and vasoconstriction of blood vessels.

• Shivering and vasodilation of blood vessels.

Which of the following will occur when the surrounding temperature drops below 10 ° C?

• R constrict

• Q relax

• P erect

• S become active

Which organ acts as a control centre of a homeostasis process?

• 
• 
• 
• 

Choose Corrective mechanisms when body temperature increases

• Hair lies flat

• Hair stands erect

• Blood vessel dilates

• Blood vessel constricts

• More sweats is produced

Choose corrective mechanisms when body temperature decreases

• Hair Lies flat , blood vessel dilates

• Hair stands erect , blood vessel constricts

• Skeletal muscles move passively

• Skeletal muscle move actively - shivering

• decrease sweating

Why our hair will stands erect during cold days?

• To increase body metabolism

• To trap air which acts as heat insulator

• To let more blood flows near skin surface

• To cool down skin when sweats is evaporated
