Examples of phagocytic cells
What are the 3 types of phagocytic cells?
They are a key component of the innate immune system. There are three main groups of phagocytes: monocytes and macrophages, granulocytes, and dendritic cells, all of which have a slightly different function in the body.
What are some examples of phagocytic cells?
Macrophages, neutrophils, monocytes, dendritic cells, and osteoclasts are among these dedicated cells. These professional phagocytes express several phagocytic receptors that activate signaling pathways resulting in phagocytosis.
Which type of human cell is a phagocyte?
The professional phagocytes are the monocytes, macrophages, neutrophils, tissue dendritic cells and mast cells. One litre of human blood contains about six billion phagocytes.

Is Basophil a phagocyte?
Basophils are not phagocytic; rather, when stimulated, the cells eject the chemicals contained in their granules.
Are white blood cells phagocytes?
Phagocytes are a group of white blood cells that includes neutrophils. These cells consume bacteria and other pathogens to protect the body from infection.
Are T cells phagocytes?
Lymphocytes and phagocytes are two types of cells in the immune system. The T cells, B cells, and natural killer cells are the three types of lymphocytes. Macrophages, neutrophils, monocytes, dendritic cells, and mast cells are the types of phagocytes.
Which of the following cells is not a phagocyte?
Basophil
So, the correct answer is ‘Basophil‘.
Which of the following is phagocytic?
Among the White blood cells (WBCs) four cells have the phagocytic ability. The neutrophils, monocytes, eosionophils and basophils.
What are the two main types of phagocytes?
Types of phagocytes
In humans, and in vertebrates generally, the most-effective phagocytic cells are two kinds of white blood cells: the macrophages (large phagocytic cells) and the neutrophils (a type of granulocyte).
What are the two important phagocytic cells?
In the blood, two types of white blood cells, neutrophilic leukocytes (microphages) and monocytes (macrophages), are phagocytic.
What types of cells are phagocytes quizlet?
Part A – What Types of Cells Are Phagocytes? Most phagocytes are types of white blood cells, but not all white blood cells participate in this process. Select the cell types that are actively phagocytic. The actively phagocytic cells include neutrophils, eosinophils, macrophages, and dendritic cells.
What does Phagocytose mean?
(FA-goh-sy-TOH-sis) The process by which a phagocyte (a type of white blood cell) surrounds and destroys foreign substances (such as bacteria) and removes dead cells.
Are T cells phagocytes?
Lymphocytes and phagocytes are two types of cells in the immune system. The T cells, B cells, and natural killer cells are the three types of lymphocytes. Macrophages, neutrophils, monocytes, dendritic cells, and mast cells are the types of phagocytes.
Which of the following cells is not a phagocyte?
Basophil
So, the correct answer is ‘Basophil‘.
Which white blood cell is not phagocytic?
Lymphocytic/Basophil
So, the correct answer is ‘Lymphocytic/Basophil‘.
What are the 4 types of phagocytes?
The main types of phagocytes are monocytes, macrophages, neutrophils, tissue dendritic cells, and mast cells.
Is eosinophil a phagocyte?
Eosinophils (acidophils)
They are phagocytic and engulf antibody-coated or marked foreign substances. Their primary mode of attack is the exocytosis of toxic compounds, including nitric oxide, and cytotoxic enzymes, onto the surface of their targets.
Are NK cells phagocytic?
NK cells are non-phagocytic lymphocytes that are responsible for innate immunity via elimination of virus or bacteria-infected cells, as well as transformed cells.
Is a neutrophil a phagocyte?
The neutrophil is the major phagocyte of the innate immunity and plays a key role in the host defense against staphylococcal infections.
What are basophils cells?
A type of immune cell that has granules (small particles) with enzymes that are released during allergic reactions and asthma. A basophil is a type of white blood cell and a type of granulocyte.
Are monocytes phagocytic?
Monocytes are phagocytic leukocytes of the blood that, in conjunction with tissue macrophages and neutrophils, are important cells involved in first-line defense against pathogenic organisms or foreign cells (Fig. 19.4).
