Question

regulate blood flow into the capillary bed and respond to local chemical conditions. If the tissue is metabolically active, they would _________________________ in diameter to allow flow into the tissue. If the tissue is not metabolically active, they would _________________________ in diameter and blood would be __________________________ through the capillary bed. What are the changes in the tissues and what is a byproduct when there is active metabolism

Answer 1

Pre-capillary sphincters regulate the blood flow into the capillary bed and respond to local chemical conditions. If tissue is metabolically active it would increase in diameter to allow flow into the tissue. If the tissue is not metabolically active it would decrease in diameter and blood flow would be decreased through the capillary bed.

What are Pre-capillary sphincters?

A precapillary sphincter is a band of pericytes or smooth muscle-like contractile mural cells that regulates blood flow into capillaries. They were once believed to solely exist in the mesenteric microcirculation, where they had been first described.

Changes take place while the metabolism is active.

• A rise in the level of adenosine
• A spike in the area's carbon dioxide levels.
• An increase in blood lactate levels.
• A high pH. A drop in oxygen concentration

The tissue's metabolism slows down after it has been removed.

Since the temperature drops frequently, the reported variations must take these potential variables into account.

If the tissue is maintained via temperature and perfusion systems, it may be stabilized in a living state in vitro.

Answer 2

Pre capillary sphincters regulates the blood flow into the capillary bed and respond to local chemical conditions. If tissue is metabolically active they would increase in diameter to allow flow into the tissue. If the tissue is not metabolically active they would decrease in diameter and blood flow would be decreased through the capillary bed.

When the metabolism is operating, changes are created.

1. An increase in adenosine concentration

2. a rise in carbon dioxide levels there.

3. A rise in lactic acid levels.

4. A high pH.

5. A decrease in oxygen content

• After the tissue has been removed, the metabolism of the tissue slows down.
• The recorded variances must take these potential variables into consideration because the temperature drops often.
• The tissue may be stabilized in a live condition in vitro if it is sustained by temperature and perfusion systems.
