Examples of pinocytosis
WebFor example, when microorganisms invade the human body, a type of white blood cell called a neutrophil removes the invader through this process, surrounding and engulfing the microorganism, which is then destroyed by the neutrophil (Figure 3.26). A variation of endocytosis is called pinocytosis. This literally means “cell drinking” and was ...

In pinocytosis, the membrane forms an invagination (pocket) that pinches off, bringing into the cell the fluid in the pocket along with any solutes in the fluid. Image created by BYU-Idaho student, Hannah Crowder, 2013. A much more efficient mechanism for bringing specific solutes into the cell is receptor‐mediated endocytosis.
