So, all these guys over here, these are the true capillaries.

Then you start to take a look at adult life.

The walls are covered with villi where nutrient absorption takes place.

End to end, that would form a line that would circle the earth twice.

So we set out by looking at how these molecules are put together.

The smallest blood vessels are called capillaries.

Let me actually just gonna call them that.

So where is the blood gonna go?

He had many capillaries burst in his legs.

We've got 19 billion of them in our bodies.

Capillary dilation of the socalled blush response?

And so this by definition then, not a true capillary, because it has some smooth muscle in the wall.

Now, the first vessels, this tiny little vessel over here, it actually is not a capillary, eventhough we would assume it's a capillary,

Resisted digit abduction tests the ulnar nerve.

You've got pulmonary arteries carrying blood, you've got bronchial arteries carrying blood and that blood mixes.

It was a rare gem a brain tumor, hemangioblastoma the gift that keeps on giving.

Evaluate for the radial pulse and capillary refill.

And under the microscope, you can see hundreds of these brown stained blood vessels, capillaries that are feeding cancer cells, bringing oxygen and nutrients.

In concluding the wrist exam it is important to document a neurovascular exam.

We worked with a theme, which is, you've got macrophages that are streaming down a capillary, and they're touching the surface of the capillary wall, and they're picking up information from cells that are on the capillary wall, and they are given this information that there's an inflammation somewhere outside, where they can't see and sense.

In concluding the hip exam it is important to document neurovascular exam.

And once it's there it's gonna be kind of mixed in with the capillaries and it's gonna start getting oxygen.

And we then can re perfuse the liver with cells, preserving the blood vessel tree.

In concluding the knee exam, it's important to document a neurovascular exam.

You place the muscle cells on the outside.

And so we see a mushroom here sporulating.

In concluding the ankle and foot exam, it's important to document neurovascular.

Osteoblastoma is present in the posterior area of the lumbar.

And what we do is we, to make a blood vessel, same strategy.

Alan, look at this. ...the amount of blood distending your vessels, imperfections in the skin...

Blood flows through blood vessels.

It's gonna be going initially through a giant vessel.

And the processes that cause this are things like arteriosclerosis for the large vessels or arteriolosclerosis for the small vessels.

And in fact, every cell in our body has a little blood vessel that's near by.

And the capsules in her blood stream.

Blood runs in the veins.

You know, where did these things come from?

And the first thing that makes me think is that blood vessels are like highways for the tumor cells.

And once those vessels invade the cancer, it can expand, it can invade local tissues, and the same vessels that are feeding tumors allow cancer cells to exit into the circulation as metastases.

Incidentally, that the gills of fish are bright red is because there are many 'capillary vessels' collected there, the same as for lungs.

We can do this because tumor blood vessels are unlike normal, healthy vessels we see in other places of the body they're abnormal, they're very poorly constructed, and because of that, they're highly vulnerable to treatments that target them.

It's gonna go every which ways, gonna go down this way as well, into all these two capillaries.

For example, insufficient angiogenesis not enough blood vessels

Rashes, hair loss...

Shut your mouth!
