Calcium flows through t-tubules.
In response to stimulation, calcium channels in t-tubules open and allow calcium to flow down it's electro-chemical gradient into the cell. In skeletal muslce it contributes greatly to muscle contraction.
The purpose of t-tubules is to allow depolarization to quickly penetrate to the interior of the cell. The t-tubules help to bring the extracellular environment to all parts of the muscle cell more quickly which better coordinates muscle contraction.

The T-tubules are part of the triad that interconnect the sarcoplasmic reticulum (SR). They make contact with the terminal cisternae of the SR.
Their function is to conduct the action potential throughout the muscle fiber, deeper into the muscle for contraction.
