Which chemicals are secreted by T-helper cells to stimulate b-plasma cells to divide?
These chemicals are called CYTOKINES.
What is the medical term meaning chemicals released by neurons that stimulate other cells?
Chemicals released by neurons are called neurotransmitters
Immune cells that destroy bacteria with chemicals need an abundance of what?
lysosomes
Which immune cells are attracted to the chemicals secreted by helper T cells?
Cytotoxic t cells and b lymphocytes!
What is a network of cells tissues organs and chemicals that fight pathogens?
The immune system is a network of cells tissues organs and chemicals that fight pathogens. This is how the body keeps healthy and defends against invading illnesses.
What immune system cells are attracted to the chemicals secreted by helper T cells?
Cytotoxic t cells and b lymphocytes!
Which describes T cells?
They produce chemicals to fight infection and later produce chemicals to "turn off" the immune system.
What is a network of cells tissues organs and chemicals that fights off pathogens?
immune system
How does white cells divide?
White blood cells, or leukocytes, divide through a process called mitosis. In mitosis, the cell’s DNA replicates, and then the cell divides into two identical daughter cells. This allows white blood cells to replenish their numbers and help maintain a healthy immune system.
What chemicals secreted by t cells in response to antigens?
Cytokines such as interferrons and interleukins are secreted by the T cell in response to antigen. These chemicals are also secreted by B cells, dendrictic cells and natural killer cells. These chemicals are signalling agents that modulate (or properly control) the immune response
Does radiation kill the immune cells or help them function better?
Radiation can have both suppressive and stimulatory effects on the immune system. In high doses, radiation can damage or kill immune cells, leading to immune suppression. However, at lower doses, radiation can actually stimulate the immune response by promoting the release of immune-stimulating molecules and activating immune cells. The overall impact on immune function depends on the dose, duration, and tissues/organs exposed to radiation.
Cells of the skin that are active in the immune process are called?
Langerhans Cells
