F16-05: Histology of Vessels and Starling's Law of the Capillary

For this assignment, you will match the types of vessels and their structures on the left to the corresponding terms on the right.

Arteries

These vessels have a thick tunica media of smooth muscle to allow for dilation and constriction for movement of blood

For this assignment, you will match the types of vessels and their structures on the left to the corresponding terms on the right.

Veins

These vessels have a very thick tunica externa and in general do not control their own flow

For this assignment, you will match the types of vessels and their structures on the left to the corresponding terms on the right.

Valves

These are found in veins to regulate flow of blood and prevent backflow

For this assignment, you will match the types of vessels and their structures on the left to the corresponding terms on the right.

Elastic arteries

These are generally larger arteries that must expand and contract as pulse pressure changes; the aorta is an example

For this assignment, you will match the types of vessels and their structures on the left to the corresponding terms on the right.

Muscular Artery

These vessels have larger smooth muscle layers to control blood flow; an example is the brachial artery

For this assignment, you will match the types of vessels and their structures on the left to the corresponding terms on the right.

Capillary

These vessels are microscopic and have very thin walls to allow for gas and nutrient exchange between the bloodstream and tissues

This image is an example of what type of capillary?

Continuous

This image is an example of what type of capillary?

Fenestrated

This image is an example of what type of capillary?

Sinusoid

Using this image as a guide, what would the net movement of fluid be if capillary hydrostatic pressure was 40 mm Hg and blood colloidal osmotic pressure was 40 mm Hg?

 

No net movement

Using this image as a guide, what would the net movement of fluid be if capillary hydrostatic pressure was 35 mm Hg and blood colloidal osmotic pressure was 25 mm Hg?

 

Fluid would move into the tissues

Using this image as a guide, what would the net movement of fluid be if capillary hydrostatic pressure was 25 mm Hg and blood colloidal osmotic pressure was 32 mm Hg?

 

Fluid would re-enter the capillary
