Explanation:
Vaso vasorum are defined as the small network of blood vessels present in large veins and arteries responsible for the blood supply and nourishment of large blood vessels.
There are three types of vaso vasorum including Vasa vasorum internae, Vasa vasorum externae, and Venous vasa vasorae. These three vessels together contribute for blood supply to the walls of large blood vessels like arteries and veins.
Arteries are having high pressure so the vasa vasorum serves for the outer layer of arteries and veins are having lower pressure which allows the vasa vasorum to get closer to the lumen and serves for nourishment of veins.
Hence, the given statement is true.
Answer:
A major advantage of cohort studies over case-control studies with respect to the role of a suspected factor in the etiology of a disease is that they permit direct estimation of risk of disease in those exposed to the suspected factor.
Explanation:
The major advantage of cohort studies over case control studies are :
1.It is suited for rare exposures since starting with exposure status.
2.Allows for studying several outcomes.
3.Exposure status easier to ascertain since starting point of the study.
4.Allows computation of risk and rates.
5.Allows studying natural history of disease, easier to show that cause precedes effect.
6.Easiness to find a reference group
, usually not difficult to identify an unexposed population.
7.Sample size taken is large.
8.Concept
s are easy to understand.
Their action is to break down substrates that are bound together on the activation site. And also they react as a catalyst so that speed up processes
