Jus trying to check my answers before turning in my assignment. Thank you for your help!

Answer 1

1. b. Clean up foreigner invaders in our body

Macrophages kills the foreigner invader by the process of phagocytosis ,it engulf the invaders and digset them.The mast cells and basophils functions in responding to the parasitic infections.T cell activation occurs when T cells receptor present on the CD4+ helper cells and CD8+ cytotoxic cells bounds to the antigen.

2.c. Helps produce an immune response to infection

The lymphatic system is the component of immune system, helps in maintaining the balance of fluid and absorbs fat. The lymphatic system composed of extensive network of vessels and lymph flowing through them ,monitor the pathogens and kill them before causing infections.

3.b. Cause cells to become leaky

Mast cells which is already IgE primed releases the chemical mediator compounds to trigger the inflammation from stored granules. It releases the histamines,cytokines ,heparin and other proteases in the environment . Thus, prevents the bacteria or other pathogens to enter into the cell.

4.a. Antibodies

The B lymphocytes cells produced in bone marrow and get matured in spleen and forms the naive mature B cells. It produces antibodies which helps in humoral immunity. Killer T cells is produced by the T lymphocytes ,helps in killing the transformed cells.
