Best Answer: Not Much... some of it depends on how many students there are, lets say you teach four classes a week with fifteen students in your class... the average is matbe $30 to $40 a class...so lets say in a month of teaching classes you can make $640.00.ome of it depends on how many students there are, lets say you teach four classes a week with fifteen students in your class... the average is matbe $30 to $40 a class...
Veins have generally been discussed in qualitative, relative terms, as âmore compliant than arteriesâ, subject to âlower pressuresâ. Arteries have thicker walls than veins and contain more smooth muscle tissue and elastin.
Therefore, most veins carry deoxygenated blood and most arteries carry oxygenated blood. However, the pulmonary veins carry oxygen rich blood to the heart, and the pulmonary arteries carry oxygen poor blood to the lungs. So, in short: no they do not carry blood all the time; the pulmonary veins carry oxygenated blood. Source(s): B.S. in Biology. MayDay Â· 6 years ago.
