Phagocytes and lymphocytes are white blood cells included in the immune response. (A) Explain the role of lymphocytes in the immune response (3)

(B) Phagocytes ingest Bacteria
Explain what happens to bacteria after they have been ingested by phagocytes. (3)

Respuesta :

Answer:

(A) Lymphocytes play a crucial role in the immune response by recognizing and targeting specific pathogens. There are two main types: B cells, which produce antibodies, and T cells, which directly attack infected cells. This targeted response helps the immune system eliminate specific threats.

(B) Once phagocytes ingest bacteria, they undergo a process called phagocytosis. The bacteria are engulfed by the phagocyte's membrane, forming a phagosome. Subsequently, the phagosome fuses with lysosomes containing digestive enzymes, leading to the breakdown of the bacteria and eventual elimination.

Answer:

(A) Lymphocytes are a type of white blood cell that play a major role in the immune response. There are two main types of lymphocytes: B cells and T cells. B cells produce antibodies, which are proteins that bind to and neutralize specific antigens. T cells help to regulate the immune response and can also kill infected cells.

(B) Phagocytes are white blood cells that engulf and destroy foreign particles, such as bacteria. When a phagocyte ingests a bacterium, it releases enzymes that break down the bacterium's cell wall. The phagocyte then digests the bacterium's remains.

Phagocytes are important for the immune system because they help to protect the body from infection. They are also involved in the removal of dead cells and debris from the body
