change in Blood Pressure across a vascular bed = C.O. x TPR

Vessels in general

Know the names of the different parts of the vascular system.

What is main function of each part of the system-

Compare and contrast the anatomy of the arteries -capillaries--veins

What tissue in the vasculature system is responsible for changing lumen diameter?

Give the definition of compliance.( in words and equation)

• Compare the compliance/distensibility of arteries & veins. (draw a graph and label axes and draw line to represent arteries,veins)
• What is the anatomical basis of compliance? what is the physiological consequence of this difference?
• How can compliance of a vessel change?

How does the velocity of blood cahnge over the vacular bed--

• what is responsible for this change

How does the blood pressure change over the vascular bed of the circulatory system?

Arteries

What is the driving force for movement of blood?

What is pulse pressure? What factors can alter pulse pressure?

Why doesn’t the diastolic pressure drop to zero?

How do you figure out mean arterial pressure? What is the importance of mean arterial pressure?

Be able to draw a graph representing the change in blood pressure through the cardiac cycle.

How much does blood pressure drop across the arteries?

 Arterioles

How can the body decrease the resistance in the vascular tree? How does this change BP?

What local factors contribute to autoregulation of arteriole diameter?

What type of factors are considered extrinsic regulators of the resistance in an arteriole?

How is it possible for the sympathetic nervous system to cause vasodilation in the capillary bed of skeletal muscles? and vasoconstriction in skin vessels?

During exercise how does blood flow to the following regions change?
brain, skeletal m., heart, skin, kidney, small intestines

 Capillaries---Transfer of Fluids

What is the driving force for the movement of small molecules, gases between the capillary and the interstitial space?

What is the difference between crystaloids and colloids?

How does the crystaloid content of blood and interstitial fluid compare? the colloid content.

Where in your body is albumin made?

What is the driving force for the movement of fluid between capillary and interstitial space?

What determines the hydrostatic pressure in the capillaries?

What determines the osmotic pressure of the blood?

If the arterioles constrict will fluid be lost or gained at the capillaries? Why?

If arterioles dilate will fluid be lost or gained at the capillaries? Why?

What is edema? What causes it?

How can the interstitial fluid be a source of fluid replacement during hemorrhage?

Venous Return:

List 3 factors that assist venous return of blood to the heart?

 Regulation of Blood Pressure

What are baroreceptors? where are they found?

What do they monitor?

As blood pressure increases what happens to the number of AP sent tot he brainstem?

To what part of the brain do they send information?

How do they regulate blood pressure?

What tissue is regulated by the cardiovascular centers of the brain?
