Fl Eoc Blood Pressure and Viscosity

Which of the following does this definition represents : The more viscous a liquid, the more its molecules resist being put into motion and staying in motion.

• Blood Viscosity

• Blood vessel radius

• Blood vessel lenght

• Blood pressure.

Which of the following factors can affect peripheral resistance

• Decrease In vessel Lenght

• Decrease Blood viscosity

• Increase in Vessel diameter

• Obstruction in vessels

T/F - The longer the blood vessel, the greater the resistance

• T

• F

T/F - If CO increases, BP decreases

• T

• F

T/F - The total amount of blood volume is directly linked to the amount of water in the blood.

• T

• F

T/F - As peripheral resistance increases, Blood pressure increases

• T

• F

If blood pressure suddenly dropped below a normal range, which of the following would occur in response?

• Baroreceptor firing rate would increase, sending signals to the medulla

• Increased activity of the sympathetic nervous system on the heart

• Increased activity of the parasympathetic nervous system on the heart

• Vasodilation to decrease peripheral resistance
