Phagocytosis
Cells are able to remove large amounts of material through a process called endocytosis, where they engulf particles or molecules by forming vesicles around them. This allows the cell to take in nutrients, regulate signaling molecules, and remove waste products. Cells also use exocytosis to expel material outside of the cell by fusing vesicles with the cell membrane.
Engulfment processes that require ATP include phagocytosis, where cells engulf solid particles, and endocytosis, where cells engulf fluids and molecules. ATP is needed to power the rearrangement of the cytoskeleton and membrane components during these processes.
The process of recycling dead cells is carried out by specialized cells called phagocytes. These cells engulf and break down the dead cells, recycling their components into new molecules that can be used by the body for energy or building new cells.
To 'engulf' bacteria if you have an infection
The process by which specialized cells engulf large particles is called phagocytosis. During phagocytosis, the cell extends its membrane around the particle to form a phagosome, which is then fused with lysosomes to digest the particle. This process helps in removing pathogens, debris, and other foreign materials from the body.

Exocytosis is the method that most cells use in order to dispose of large molecules of waste materials.
Endocytosis is a cellular process where cells engulf external materials by forming vesicles around them. This allows cells to take in nutrients, remove waste, and regulate signaling molecules.
Endocytosis:==> Phagocytosis or Pinocytosis. Endocytosis is the name given to the process of cells absorbing molecules. Pinocytosis is intended for small molecules Phagocytosis is for large particles. (larger then ~around 0.75 µm in diameter)
Macromolecules
These are called macromolecules.
The uptake of large particles is called phagocytosis. Phagocytosis is a process where cells, such as macrophages and neutrophils, engulf and internalize large particles, such as bacteria, cell debris, or foreign substances, for degradation and elimination.
