Why is the blessed sacrament takeaway to a side chapel rather than left in the tabernacle?

The Blessed Sacrament is often taken to a side chapel for adoration or prayer to provide a space for quiet meditation and reflection, allowing the faithful to engage more personally and intimately with the presence of Christ. This practice emphasizes the importance of the Eucharist while also creating a dedicated environment that fosters devotion and prayer. Keeping the Blessed Sacrament in a side chapel can also help maintain a sense of reverence and focus, separate from the main liturgical activities in the church.
