Detailed explanation-1: -Answer and Explanation: The action of macrophages in cells is an example of phagocytosis. Macrophages can engulf and destroy bacteria or other foreign particles because they have a phagocytic vacuole, an area within the cell that can engulf and digest particles.

Detailed explanation-2: -Abstract. Macrophages can internalize the invading pathogens by raft/caveolae and/or clathrin-dependent endocytosis and elicit an immune response against infection. However, the molecular mechanism for macrophage endocytosis remains elusive.

Detailed explanation-3: -Phagocytosis (cellular eating) This is a specialised form of endocytosis, that is usually only carried out by specialised cells, for example, macrophages and other white blood cells .

Detailed explanation-4: -And the examples of endocytosis are the leukocytes, neutrophils and monocytes which engulf the foreign particles such as bacteria, etc. And the Metabolism of Cholestrol is a best example for receptor mediated endocytosis.

Detailed explanation-5: -Macrophages don’t eat cells the same way you might eat your food. Instead, the eating machines engulf viruses and bacteria. This is called phagocytosis. First, the macrophage surrounds the unwanted particle and sucks it in.
