Mouse One has a defect that prevents T lymphocytes from maturing. Mouse Two has a defect that prevents complete thymus development. Neither mouse has mature T cells. What is one way to induce the development of mature T cells in Mouse One?

Foreign particles floating in the blood are going to be filtered by the --------.

[blank_start]Bone Marrow[blank_end]-location hematopoietic cell division + B cell development [blank_start]Thymus[blank_end]- Location of T cell development [blank_start]Lymph nodes[blank_end]- filter blood; trap pathogens; activate antibody production [blank_start]Spleen[blank_end]- Filter blood; store and filter platelets; store immune cells [blank_start]Tonsils[blank_end]- contain immune cells that activate immune system when they contact pathogens [blank_start]Bowel[blank_end]- B cells in the lymphatic tissue produce antibodies; microbiome to prevent pathogen colonization

[blank_start]CRISPR[blank_end] and [blank_start]CAS[blank_end] DNA recognize viral DNA and process them so they cannot be expressed.

Innate cells include: [blank_start]epithelial barriers[blank_end], [blank_start]phagocytes[blank_end], [blank_start]complement[blank_end] and [blank_start]NK cells[blank_end] Adaptive cells include: [blank_start]B-lymphocytes[blank_end] (which produce [blank_start]antibodies[blank_end]) and [blank_start]T-lymphocytes[blank_end] (which produce [blank_start]killer[blank_end] or [blank_start]helper[blank_end] types)

Innate cells respond in the next few days after an infection while adaptive cells respond within hours.

Hemocytoblast is another word for Hematopoietic stem cells

Hemocytoblasts can become either [blank_start]Myeloid stem cells[blank_end] or [blank_start]Lymphoid stem cells.[blank_end] Eosinophil, Basophil and Neutrophil are all [blank_start]polymorphonuclear leukocytes[blank_end] Monoblasts have [blank_start]one[blank_end] nucleus and Myeloblasts have [blank_start]mulitple[blank_end] T cells are developed in the [blank_start]thymus[blank_end] and B cells in the [blank_start]bone marrow[blank_end]

The thymus and spleen are both primary immune organs.

Which of the following is not a secondary immune system organ? Lymph nodes, Peyer's Patches, Tonsils, Bone marrow, Lymphatic vessels, Adenoids

GALT stands for Gastro-associated lymphatic tissue.
