In the human body the circulator system transports and delivers substances. Within the cell which organelle performs a similar function?

Within the cell, the organelle that performs a function similar to the circulatory system is the endoplasmic reticulum (ER). The ER transports proteins and lipids synthesized in the cell to various destinations, either within the cell or for export outside. Additionally, the Golgi apparatus further processes and sorts these substances, akin to how the circulatory system distributes nutrients and waste. Together, these organelles facilitate the movement and delivery of essential materials within the cell.
