ANS Lecture 8

Question 1

What is the equation for blood pressure?

Answer 1

Cardiac Output multiplied by Total Peripheral Resistance

Question 2

What is the formula for Cardiac Output?

Answer 2

Heart rate multiplied by Stroke volume

Question 3

What is Stroke Volume?

Answer 3

How much blood comes out of the heart with each beat

Question 4

What factors determine blood pressure?

Answer 4

• Heart Rate
• Force of Contraction
• Resistance of arterials

Question 5

What do Baroreceptors sense?

Answer 5

When blood pressure goes up or down

Question 6

How do the Parasympathetic and Sympathetic nervous systems function in response to increased blood pressure?

Answer 6

The Parasympathetic nervous system decreases heart rate and the force of contraction. Decreases sympathetic nervous system does this as well
Decreased sympathetic causes blood vessels to dilate

Question 7

Which part of the Nervous System controls temperature regulation?

Answer 7

The sympathetic nervous system

Question 8

How does the Sympathetic nervous system increase body temperature?

Answer 8

The sympathetic nervous system increases activity to skin causing piloerection, cutaneous blood vessels causing vasoconstriction, and various tissues increasing metabolism
It also decreases activity to sweat glands
