Homeostasis Mechanism

What changes occur to cool the body down?

• Vasoconstriction, increase sweating and hairs lie flat

• Vasodilation, increase sweating and hairs lie flat

• Vasodilation, reduced sweating and hair stand up

• Vasoconstriction, increase sweating and hairs lie flat

What are the variables responsible for Homeostasis? Tick all that apply.

• Blood pressure

• Body temperature

• Blood glucose

• Body fluids

Homeostatic cooling mechanisms include:

• Piloerection and vasoconstriction

• Sweating and piloerection

• Sweating and vasodilation

Which body system controls the body to maintain homeostasis?

• excretory (blood filtration an waste removal)

• nervous

• circulatory

• skeletal

Stimulus causes a response that returns a condition back to homeostasis

• Negative Feedback

• Positive Feedback

Sweat Glands produce less fluid

• endocrine system

• circulatory system

• muscular system

• nervous system

what is the function of integumentary system (skin & connective tissue) to control body temperature high?

• arterioles in the epidermis dilate so that more blood flow to the skin
• produce hormones to reduce the metabolic rate
• sweat glands in the skin produce more sweat and hair erector mucles relax to let the hair lie down
• detect the temperature and send to nerve impulses to the brain

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

These are responses when body temperature increases:

• Vasoconstriction, shivering

• Vasoconstriction, sweating

• Vasodilation, shivering

• Vasodilation, sweating

Brain recognizes temperature drop

• endocrine system

• circulatory system

• muscular system

• nervous system
