A large active phagocyte cell is typically a macrophage, which plays a crucial role in the immune system by engulfing and digesting pathogens, dead cells, and debris. These cells are derived from monocytes and can migrate to tissues where they differentiate into macrophages. They are essential for both innate and adaptive immunity, as they not only clear infections but also help activate other immune cells. Macrophages can also exhibit plasticity, adapting their function based on the signals they receive from their environment.

Is a mast cell a lymphocyte or a phagocyte?
A mast cell is not a lymphocyte or a phagocyte. It is a type of white blood cell involved in the immune response, particularly in allergies and anaphylaxis, by releasing histamine and other inflammatory mediators.
What is the medical term meaning white blood cell phagocyte and precursor of a macrophage?
The medical term for a white blood cell phagocyte and precursor of a macrophage is a monocyte. Monocytes circulate in the bloodstream before migrating to tissues, where they can mature into macrophages to help with immune responses and clearing infections.
What is the white blood cell that attacks the invading pathogens?
The white blood cell that attacks invading pathogens is called a neutrophil. Neutrophils are a type of phagocyte, which means they engulf and destroy pathogens through a process called phagocytosis. They are an important part of the body's immune response to infections.
How is the cell structure of a phagocyte unique?
Phagocytes, such as macrophages and neutrophils, possess a unique cell structure characterized by a large number of lysosomes, which contain digestive enzymes essential for breaking down pathogens and debris. Their flexible plasma membrane allows for the extension of pseudopodia, enabling them to engulf foreign particles through a process called phagocytosis. Additionally, they often have a prominent nucleus that can be irregularly shaped, reflecting their active role in immune response and the processing of engulfed materials.
Large molecules are surrounded by the cell membrane and enter the cell?
Large molecules can enter cells through processes like endocytosis, where the cell membrane surrounds the molecule and engulfs it in a vesicle. This allows large molecules to be transported into the cell without crossing the lipid bilayer of the membrane.
Is a mast cell a lymphocyte or a phagocyte?
A mast cell is not a lymphocyte or a phagocyte. It is a type of white blood cell involved in the immune response, particularly in allergies and anaphylaxis, by releasing histamine and other inflammatory mediators.
A cell which eats?
Phagocyte**
Do phagocyte cell have nucleus?
yes
What phagocyte cell occupies the epidermis?
Langerhan's cells.
A large white blood cell that can destroy substances such as cell debris dust pollen and pathogens by the process of phagocytosis?
The white blood cell described is likely a macrophage. Macrophages are immune cells that engulf and digest foreign particles, such as cell debris, dust, pollen, and pathogens, through a process called phagocytosis. They play a vital role in the immune response by helping to eliminate harmful substances from the body.
What is the large phagocyte found in the lymph nodes?
MACROPHAGE
How does hiv attach to the host cell?
with the help of lymphocyte and phagocyte
What can large particle can enter a cell by an active-transport process?
The cell Wall
What is the medical term meaning cell that ingests particulate matter?
A phagocyte is a cell specializing in ingestion of materials.
Is phagocytosis active or passive transport?
Phagocytosis is considered an active process because it requires energy expenditure by the cell to engulf and digest particles such as bacteria or cell debris. It is a form of endocytosis where the cell engulfs solid particles rather than fluids.
What eats foreign things in the body?
Antibodies. phagocyte - a white blood cell
An active cell might contain large numbers of these?
mitochondria
