DownloadWhy is the RVEDP different from the LVEDP?
Omdraaien
As the LV muscle fibers get bigger, there is less room in the left chamber for blood. The EDP is different in the LV and the RV because the RV has much more room for the blood left than the LV because it is full of dilated muscle fibers. This increases the pressure.
The muscle fibers of the coronary arteries run circular to the artery. True or False?
Omdraaien
False. They run longitudinally (the length) of the artery. If they wrapped around the coronary artery, then the blood would be squeezed/compressed but not move. The contraction of arteries is done in a systematic way.
The intima of an artery is covered in what kind of cells?
Omdraaien
Endothelium.
What is a major issue with endothelium in the arteries?
Omdraaien
The endothelium does not stick to the muscle fibers of the media very well. They are washed away easily by turbulent flow.
What are the four main jobs of the endothelium?
Omdraaien
1. Create a slippery environment for blood flow2. Reproduce quickly to replace any lost endothelial cells.3. Make nitric oxide to dilate the arteries and make easier flow.4. Act as a magnet for bad cholesterol.
What is the media part of an artery?
Omdraaien
The muscle layer.
What is the adventitia layer of an artery?
Omdraaien
It is the outside layer of the coronary artery. It allows O2 to come in to give the muscle fibers what they need to do their job.
What is the pressure of the arterioles delivering O2 to the adventitia of an artery?
Omdraaien
7-12mmHg.

When you inflate a balloon into an artery and the balloon is on healthy parts of the artery, it causes muscle damage and injures the capillaries. True or False?
-
A lesion in a coronary artery exerts pressure on the cell wall causing the arterioles not to be able to deliver O2, causing the muscle fibers to start to die, and making the artery less able to expand and contract. True or False?
-
When we expand a balloon, we are resetting the muscle fiber memory so that it believes that the over-expansion is normal. True or False?
