What does atherosclerosis of aorta mean?
Having atherosclerosis (say “ath-uh-roh-skluh-ROH-sis”) of the aorta means that a material called plaque (fat and calcium) has built up in the inside wall of a large blood vessel called the aorta. This plaque buildup is sometimes called “hardening of the arteries.”
How does atherosclerosis cause aneurysms?
When this point is reached, the wall begins to dilate (grow larger) in the area of the plaque. As the diameter of the vessel grows, the wall tension increases, leading to even more dilation. The end result is an aneurysm.
What is abdominal atherosclerosis?
About Atherosclerosis Atherosclerosis is a major cause of abdominal aortic aneurysm and is the most common kind of arteriosclerosis, or hardening of the arteries. This disease process can be seen in any blood vessel in the body and is the cause of coronary artery disease, stroke, and peripheral arterial disease (PAD).
How serious is calcification of the abdominal aorta?
Abdominal aortic calcification is shown to contribute to arterial stiffness and is a strong predictor of cardiovascular events and mortality.
What are the three types of constitutional isomers?
Recall that there are three types of constitutional isomer commonly seen: Chain, positional and functional. Isomers are molecules that have the same molecular formula, but have a different arrangement of the atoms in space.
Is the constitutional isomer the same as ethyl alcohol?
Constitutional isomers can also have different functional groups. For example, both ethyl alcohol and dimethyl ether have the same molecular formula: C 2 H 6 O. Although the molecular formulas of the two compounds are identical, their functional groups differ ( Figure 2.5 ).
How are the five constitutional isomers of the hexanes illustrated?
The five constitutional isomers of the hexanes are illustrated in structures 1 – 5. Structure 1 can be rearranged to form the other four constitutional isomers. If you use an imaginary pair of “chemical scissors” to cut off a methyl group from the chain you will be left with a C 1 and C 5 fragment.
How many constitutional isomers are there in pentane?
Two molecules which have the same molecular formula but different structural formulas, or bonding arrangements, are known as constitutional isomers. Pentane is an alkane with five carbon atoms. It has three constitutional isomers, shown below.
