Macrophages in the lungs prevent pneumonia infections by surrounding, engulfing, and destroying streptococcus pneumoniae bacteria. this is an example of which type of endocytosis?

Sagot :

The lungs prevent pneumonia infections by surrounding, engulfing, and destroying streptococcus pneumoniae bacteria this is an example of Phagocytosis.

  • Alveolar macrophages, also known as pulmonary macrophages or dust cells, are specialised phagocytes that are located in the airways and at the level of the alveoli in the lungs but are not attached to their walls.
  • Following the formation of this bridge, membrane protrusions encircle the bacteria and take them into the phagosome, which is created by the fusion of cell membranes.
  • Invading bacteria are first encountered by macrophages, which are also in charge of phagocytosing and digesting pathogens to start the innate inflammatory response.
  • The phagocytic/endocytic and lysosomal pathways, which contain proteolytic enzymes such cathepsins, are closely related and enable intracellular digestion.
