Lumen: A lumen (lm) is the International System of Units (SI) measurement for luminous flux (brightness). It is defined as: the amount of light emitted when considering a solid angle of one steradian (sr), from a source that discharges to an equal light in all directions, with the strength of one candela (cd). The unit is defined in terms of. There are two types of endoplasmic reticulum: rough endoplasmic reticulum (rough ER) and smooth endoplasmic reticulum (smooth ER).

As a result, the lumen can be much larger to assist blood flow return to the heart. There is no need to increase blood pressure in the veins, as venous return is achieved through valves to stop back flow of the blood, the skeletal muscle pump (contractions of muscles essentially squeeze the veins) and the thoracic pump (breathing creates a negative pressure in the thoracic cavity which helps.
