According to the research, the primary purpose of membrane channels is to circulate ions, and of membrane pumps is to maintain differences in ionic concentration.
<h3>What are membrane channels and pumps?</h3>
They are pores in the cell membrane through which ions circulate for muscle contraction or membrane potential changes that may depend on a ligand or voltage, depending on whether their opening is determined by the binding of a ligand or by changes of voltage.
In this sense, membrane pumps is the mechanism of active ion transport, consuming energy across a membrane against an electromechanical gradient to maintain differences in ion concentration between the intracellular and extracellular space.
Therefore, we can conclude that according to the research, the primary purpose of membrane channels is to circulate ions, and of membrane pumps is to maintain differences in ionic concentration.

Answer:
Hepatic vein, any of a group of veins that transports blood from the liver to the inferior vena cava, which carries the blood to the right atrium of the heart. In its ascent to the heart, the inferior vena cava passes along a groove in the posterior side of the liver, and it is there that the hepatic veins join it.
