Thermoregulation

What happens if your core body rises above 40^oC?

• Hyperthermia

• Hypothermia

• Hypertonic

• Hypotonic

Three ways you body can lose heat

• Evaporation of sweat

• Warm air exhaled out

• Hairs becoming erect

• Vasodilation

Thermoregulation is an example of a...

• positive feedback loop

• negative feedback loop

What is involuntary contractions of voluntary muscles to warm up?

• Shivering
• Sweating
• Vasodilation
• Vasoconstriction

Protein substance of complex fibers that gives skin its strength

• collagen

• elastin

• hyaluronic acid

This gland releases an oil known as sebum.

• Sebaceous gland

• Apocrine Gland

• Eccrine Gland

A slight sunburn might be an example of a:

• 1st degree burn

• 2nd degree burn

• 3rd degree burn

• 4th degree burn

Why can you often not feel third-degree burns?

• Because they damage the nerve ending in your skin

• Because they aren't very damaging

• Because they cause scabs to form

• Because they only affect the inner part of your skin

What is the most painful type of burn?

• First-degree burns, because the outer skin is so sensitive
• Third-degree burns, because they are the most severe
• Second-degree burns, because nerve endings are still intact even though tissue damage is severe
• All types of burns are excruciatingly painful

What happens when the body temperature gets too low?

• Vasoconstriction

• Vasodilation

• Hair erector muscles contract

• Hair erector muscles relax

• Sweat glands stop producing sweat
