What else can I help you with?
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.
May destroy infected cells select one a cytotoxic t cells b helper t cells c b cells d allergens e phagocytic cells?
a) Cytotoxic T cells are responsible for identifying and destroying infected cells by releasing toxic chemicals that induce cell death. Helper T cells aid in coordinating the immune response by activating other immune cells. B cells produce antibodies that can neutralize pathogens. Allergens are substances that can trigger allergic reactions. Phagocytic cells, such as macrophages, engulf and digest pathogens or infected cells.
DO Lymphokines attack macrophages?
Lymphokines do not attack macrophages. Lymphokines are molecules released by activated T cells to regulate the immune response, while macrophages are immune cells that engulf and digest pathogens. However, some lymphokines can stimulate macrophages to be more effective in phagocytosis and killing of pathogens.
The thymus glands produce?
The thymus gland produces T-cells, which are a type of white blood cell that plays a central role in the immune system by defending the body against pathogens.
What cells engulf antigens and present fragments of them on their own surfaces where they can be recognized by cells that will deal with them?
Antigen-presenting cells, such as dendritic cells, macrophages, and B cells, engulf antigens and present fragments of them on their cell surfaces. These antigens are then recognized by T cells, particularly CD4+ helper T cells or CD8+ cytotoxic T cells, which play a key role in initiating an immune response against the antigen.
Which type of white blood cell that surrounds and kills invading cells removes dead cells and stimulates the action of other immune cells?
Macrophages, sometimes called phagocytes, engulf pathogens and cell debris and trigger T-cells and B-cells.
Are T and b cells are two types of phagocytes?
No, T and B cells are not phagocytes. T cells are a type of lymphocyte involved in cell-mediated immunity, while B cells are another type of lymphocyte responsible for producing antibodies. Phagocytes are a different type of immune cell that engulf and digest pathogens.

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 directly attacks and lyses cellular pathogens?
One mechanism that directly attacks and lyses cellular pathogens is the complement system. This system consists of a group of proteins that can form pores on the cell membranes of pathogens, leading to cell lysis. Additionally, certain immune cells, such as natural killer cells or cytotoxic T cells, can release toxic substances that directly kill pathogens.
What system does the t cell belong to?
The T cell belongs to the immune system. It plays a critical role in the body's defense against pathogens and other foreign invaders by recognizing and destroying them.

However, some lymphokines can stimulate macrophages to be more effective in phagocytosis and killing of pathogens.
What cell is the most critical cell in immunity?
T cells are considered the most critical cells in immunity, playing a central role in orchestrating the immune response by recognizing infected cells and coordinating the overall immune reaction to pathogens.
What kind of cell can engulf bacteria or make antibodies?
Inside the human body, a particular type of white blood cell called a macrophage will engulf and digest bacteria.
The thymus glands produce?
The thymus gland produces T-cells, which are a type of white blood cell that plays a central role in the immune system by defending the body against pathogens.
What is the job of a macrophage?
They are used in the first (primary) line of the immune response. These are NOT SPECIALIZED phagocytes, as you can tell, carry out their function via phagocytosis. They engulf bacteria in various ways, but usually just grab the bacteria, engulf it, let it die, and then they die. Helper T and Antibodies mark viruses and bacteria that get past these for destruction. The macrophages recognize the bacteria, and engulf them. Their primary role is to engulf bacteria. They are non-specific.
What is the T cell count of a healthy person?
A healthy person typically has a T cell count within the range of 500 to 1600 cells per microliter of blood. T cells are a type of white blood cell crucial for immune system function and response to pathogens. Fluctuations in T cell count can occur due to factors like infection, stress, or certain medical conditions.
