I think I saw PW hanging around in the students' bar earlier.
By that I mean there is a Halloween skeleton on one of the walls in the students' bar.
No, I wasn't drinking in the students' bar at 10AM. I passed by on the way to the students' coffee shop to get some tea.
Correct me if I'm wrong, but I don't think veins have muscular walls...
They do have some smooth muscle far as I know.
In general, veins function to return deoxygenated blood to the heart, and are essentially tubes that collapse when their lumens are not filled with blood. The thick outermost layer of a vein is made of connective tissue, called tunica adventitia or tunica externa. There is a middle layer bands of smooth muscle called tunica media, which are, in general, thin, as veins do not function primarily in a contractile manner.
...
Neurogenic and hypovolaemic shock can also cause fainting. In these cases, the smooth muscles surrounding the veins become slack and the veins fill with the majority of the blood in the body, keeping blood away from the brain and causing unconsciousness. Jet pilots wear pressurized suits to help maintain their venous return and blood pressure.
so they do, and it has a function (and can go wrong in certain circumstances).
Listen, I know it serves a purpose with the whole slower, longer contractions but I'm sure you could just do some sort of "Even slower oxidative fibers" and careful use of graded force.
So what, the body should sacrifice benefits such as greater elasticity of this kind of muscle (useful for eg the bladder to be able to expand more while still being able to contract and empty itself) to make studying it a little easier for the lazy students of this world?
... yeah, that sounds about right.
