Which of the following is considered a primary lymphatic organ?

Thymus

Which type of immune cell matures in the red bone marrow?

B-cells

What is the primary immunological function of the spleen?

Filtering the blood and removing old red blood cells

Which part of the spleen is primarily involved in the adaptive immune response?

White pulp

Which of the following statements correctly describes the role of lymph nodes and Mucosa-associated lymphoid tissue (MALT) in the immune system?

Lymph nodes filter lymph and facilitate immune responses, while MALT are clusters of lymphocytes found in mucous membranes that contribute to localized immune protection

Which type of white blood cell is primarily responsible for producing antibodies?

B-cells

Which type of white blood cell is the most abundant in the human body and is the first responder to bacterial infections?

Neutrophils

Which white blood cells are primarily involved in combating parasitic infections?

Eosinophils

Which type of white blood cell is primarily responsible for coordinating the immune response and directly attacking infected or cancerous cells?

T-cells

Which white blood cells release histamine and heparin and are involved in inflammatory responses?

Basophils

Which type of white blood cell transforms into a macrophage when it migrates from the bloodstream into tissue?

Monocytes

What is the primary role of mast cells in the immune system?

Releasing histamine and other mediators during allergic reactions

What is the primary function of Natural Killer (NK) cells in the immune system?

Directly destroying virus-infected cells and tumor cells

Which of the following steps is NOT part of the phagocytosis process?

Release of histamine to destroy the pathogen

Which of the following is NOT a function of antibodies in the immune system?

Directly engulfing and digesting pathogens

According to the clonal selection theory, what happens to a lymphocyte once it binds to a specific antigen?

It multiplies into a clone of cells specific to that antigen

Which of the following best describes the initial phase in the clonal selection process?

Selection of specific lymphocytes by binding to an antigen

What is the primary mechanism that generates diversity in B cell receptors (BCRs) and T cell receptors (TCRs)?

Random recombination of gene segments (V, D, J) during lymphocyte development

Which of the following best describes the role of memory cells in the immune system?

They ensure a faster and more potent response upon subsequent exposures to the same antigen

Which of the following statements correctly describes the processes of positive and negative selection of T cells during their development in the thymus?

Positive selection ensures that T cells can recognize self-MHC molecules, while negative selection eliminates T cells that bind too strongly to self-antigens
