What is the migration of phagocytes and white blood cells to an inflamed area along a chemical gradient is called?
chemotaxis
Cellular migration directed by a chemical gradient?
chemotaxis
Chemotaxis refers to the ability to?
move in response to chemical stimuli.
How do you phagocytes prevent infection?
Phagocytes are the white blood cells that protect the body by ingesting harmful foreign particles such as bacteria and dead cells. Also they are essential for fighting infections and for subsequent immunity. Phagocytes are crucial in fighting infections, as well as in maintaining healthy tissues by removing dead and dying cells that have reached the end of their lifespan. During an infection, chemical signals attract phagocytes to places where the pathogen has invaded the body. These chemicals may come from bacteria or from other phagocytes already present. Hope this will help!
Movement of a cell toward a chemical stimulus is termed?
positive chemotaxis

An oriented movement in response to light or chemical stimuli?
Movement in response to light is called phototaxis, and in response to chemicals is chemotaxis. More specifically, movement towards a stimulus is positive and away from is negative. For example, positive chemotaxis is movement of a cell towards nutrients.
What is chemotaxias?
I think you mean Chemotaxis. If it is so, then Chemotaxis is defined as a movement (taxis) in response to some chemical stimulus. In aqueous plants, the sperms (antherozoids) are attracted towards an egg (ovum), as the female organ (archegonium) of the plant releases some chemicals (sugars or organic acids) in the surrounding water. Sperms detect the stimulus and move towards the egg, such a movement is called chemotaxis.
How could a negative chemotaxis be beneficial to a bacterium that is exposed to bleach?
The media that tested negative chemotaxis due to acid production included with a 10% Bleach and 90% isopropyl alcohol solution and used new gradients depending on whether the chemical is beneficial or harmful (Lux and Shi 2004).
How are phagocytes recruited to the site of injury?
Neutrophils is the first phagocytes to migrate into the injured area. Macrophages is the phagocytic offspring of monocytes. The second line of defense is the inflammatory response, mast cells, fluid, and phagocytosis.
Cells that move toward chemicals released by damaged cells are said to demonstrate positive chemotaxis?
Positive chemotaxis refers to the movement of cells in response to the presence of a chemical gradient. In the case of damaged cells, the release of specific chemicals acts as a signal for other cells to migrate towards the site of injury. This helps in the recruitment of immune cells and facilitates the repair process in tissues.
What is a organisms reaction to stimulus?
Organisms can have many reactions to different stimulants. One example would be chemotaxis, where organisms move in response to chemical gradients.
