What is a type of active transport by which a cell surrounds a large particle?
Phagocytosis is a type of active transport in which a cell engulfs large particles or microorganisms by surrounding them with its cell membrane and forming a vesicle called a phagosome. This process is commonly used by immune cells to engulf and destroy pathogens or debris in the body.
How do T cells activate B cells in the immune response?
T cells activate B cells in the immune response by releasing signaling molecules called cytokines. These cytokines stimulate the B cells to multiply and produce antibodies that target and destroy pathogens. This process helps the immune system to effectively fight off infections.
How does the process of opsonization involve the enhancement of phagocytosis by immune cells?
Opsonization is a process where immune cells mark pathogens with molecules called opsonins, making them easier for phagocytes to recognize and engulf. This enhances phagocytosis by promoting the binding of the pathogen to the phagocyte's receptors, leading to its ingestion and destruction.
How are T helper cells activated in the immune response process?
T helper cells are activated in the immune response process when they encounter antigens presented by antigen-presenting cells, such as dendritic cells. This interaction triggers the T helper cells to proliferate and differentiate into specific subsets that help coordinate and regulate the immune response.
How are helper T cells activated in the immune response process?
Helper T cells are activated in the immune response process when they encounter antigens presented by antigen-presenting cells, such as dendritic cells. This interaction triggers the helper T cells to proliferate and differentiate into specific subsets that help coordinate and regulate the immune response.
Process by which water moves into the cells of lens is called?

What is the process by which immune cells engulf and then destroy bacteria known as?
The process by which immune cells engulf and destroy bacteria is called phagocytosis. This involves the immune cell recognizing the bacteria as foreign, engulfing it into a membrane-bound vesicle called a phagosome, and then fusing the phagosome with lysosomes containing enzymes to destroy the bacteria.
What is he process whereby cells ingest and destroy bacteria within the body called?
Phagocytosis is the process by which cells ingest and destroy bacteria in the body. This process makes up part of the immune function.
Which is only active during specific immune response?
T cells apex or B cells
How do T cells activate B cells in the immune response?
T cells activate B cells in the immune response by releasing signaling molecules called cytokines. These cytokines stimulate the B cells to multiply and produce antibodies that target and destroy pathogens. This process helps the immune system to effectively fight off infections.

Opsonization is a process where immune cells mark pathogens with molecules called opsonins, making them easier for phagocytes to recognize and engulf. This enhances phagocytosis by promoting the binding of the pathogen to the phagocyte's receptors, leading to its ingestion and destruction.
What is the process in which cells attack an organ?
Auto-immune reaction
How are T helper cells activated in the immune response process?
T helper cells are activated in the immune response process when they encounter antigens presented by antigen-presenting cells, such as dendritic cells. This interaction triggers the T helper cells to proliferate and differentiate into specific subsets that help coordinate and regulate the immune response.

Helper T cells are activated in the immune response process when they encounter antigens presented by antigen-presenting cells, such as dendritic cells. This interaction triggers the helper T cells to proliferate and differentiate into specific subsets that help coordinate and regulate the immune response.
What are the cells that combine with foreign antigens and present them to t cells called?
Those cells are called antigen-presenting cells (APCs). They include dendritic cells, macrophages, and B cells. Their role is to ingest foreign antigens, process them, and present them to T cells to initiate an immune response.
Which is only active during a specific immune responsible?
T cells apex or B cells
