Life would be very difficult and processes would drag if cells were to use active transport to move every substance to its destination.
Active transport is the movement of a substance across a cell membrane from low to high concentration with the help of energy.
Active Transport
Active because concentration in cells must remain hight than in the blood.
Active transport processes, such as the sodium-potassium pump, require cells to expend energy in the form of ATP. The energy from ATP is needed to move molecules or ions against their concentration gradient, from an area of lower concentration to an area of higher concentration.

The Active transport
Active Transport is carried out in our body cells. Active Transport uses energy to transport materials.
in the cells
Active transport is the movement of materials against a concentration difference. Active transport requires the cells energy. So when there is a higher concentration of something on one side of the cell, the cell will move it to a place where there is a lower concentration of the substance. This way it keeps everything balanced.

Just guess
Active transport
In the intestines, cells use active transport to pump nutrients such as glucose and amino acids from the intestinal lumen into the bloodstream. In the kidney, cells actively transport ions and small molecules from the blood into the nephron tubules for excretion in urine. In nerve cells, active transport is used to maintain the concentration gradients of sodium and potassium ions across the cell membrane, essential for nerve signaling.
