Both macrophages and dendritic cells are formed from the same precursor cell, the monocytes. However, the two cells serve different functions during an infection. Macrophages remain in the area of the infection and phagocytosis (engulf) foreign invaders and dead cells. Dendritic cells leave the infected tissue and travel to local lymph tissue in order to alert the adaptive immune system.
Macrophages and dendritic cells are both types of immune cells, but they have different functions. Macrophages are primarily involved in engulfing and digesting cellular debris and pathogens, while dendritic cells are specialized in presenting antigens to other immune cells to initiate an immune response. Both are important components of the immune system and work together to protect the body from infections.

What type of cell engulfs an invading pathogen and displays its antigens?
A macrophage is the type of cell that engulfs an invading pathogen through a process called phagocytosis. After engulfing the pathogen, the macrophage displays fragments of the pathogen's antigens on its cell surface to alert other immune cells to the presence of the invader.
The cell types that are most responsible for presenting foreign antigens together with surface antigens to specific receptors on the membrane of T lymphocytes are the macrophages and?
dendritic cells. These cells play a crucial role in activating T lymphocytes and initiating an immune response against foreign antigens by presenting antigens to the T cell receptors (TCR) on the surface of T lymphocytes. This interaction leads to the activation and proliferation of specific T cell populations to combat the invading pathogen.
Which white blood cells turn into macrophages in tissue?
Monocytes are white blood cells that can migrate from the bloodstream into tissues where they differentiate into macrophages. Once in the tissue, monocytes mature into tissue-resident macrophages and play a crucial role in immune responses, inflammation, and tissue repair.
What is a monoctye?
A monocyte is a type of white blood cell that is an essential part of the immune system. They help to fight infections and remove damaged cells from the body. Monocytes can also mature into macrophages or dendritic cells to perform specific functions.
Which of the following is a phagocyte cell that migrates out of the bloodstream?
A monocyte is a phagocyte cell that migrates out of the bloodstream. Upon entering tissues, monocytes differentiate into macrophages or dendritic cells, which phagocytose pathogens and debris to help initiate an immune response.
Which cell is known as antigen presenting cell?
Dendritic cells,macrophages, B cells
What cells originate from monocytes?
Macrophages and dendritic cells originate from monocytes. Monocytes are a type of white blood cell that circulate in the bloodstream and can differentiate into macrophages which are involved in immune responses and tissue repair, or dendritic cells which play a key role in presenting antigens to activate T cells in the immune system.
What are the skin macrophages that help activate the immune system?
Epidermal dendritic cells
Which cells phagocytize an antigen?
White blood cells, such as macrophages and dendritic cells, are responsible for phagocytizing antigens. Upon encountering an antigen, these cells engulf and digest it to help initiate an immune response.
Which type of cell are big eater?
Phagocytes are the type of cells known as "big eaters" because they specialize in engulfing and digesting foreign particles, pathogens, and cellular debris. Examples of phagocytes include macrophages, neutrophils, and dendritic cells.
What binds with and releases chemicals that activate B cell and T cell and and macrophages?
Antigen-presenting cells (APCs) such as dendritic cells bind with antigens and present them to B cells, T cells, and macrophages, leading to their activation. This process is crucial for initiating immune responses against pathogens and foreign substances in the body.
What type of cell engulfs an invading pathogen and displays its antigens?
A macrophage is the type of cell that engulfs an invading pathogen through a process called phagocytosis. After engulfing the pathogen, the macrophage displays fragments of the pathogen's antigens on its cell surface to alert other immune cells to the presence of the invader.
Which bone cell is derived from the bone marrow?
Osteoclasts. They are phagocytic just like macrophages and originate from the same stem cells in the bone marrow as macrophages.
What activates lymphocytes?
dendritic cell
Which cell functions as a part of the immune system?
An epidermal dendritic cell.
The cell types that are most responsible for presenting foreign antigens together with surface antigens to specific receptors on the membrane of T lymphocytes are the macrophages and?
dendritic cells. These cells play a crucial role in activating T lymphocytes and initiating an immune response against foreign antigens by presenting antigens to the T cell receptors (TCR) on the surface of T lymphocytes. This interaction leads to the activation and proliferation of specific T cell populations to combat the invading pathogen.
