The three pathways of the complement system are the classical pathway, alternative pathway and lectin pathway all leading to the activation of MAC.
Continue readingThe primary lymphoid organs are thymus, Bursa Fabricius, and bone marrow while the secondary lymphoid organs are those that are encapsulated & and those that are non-capsulated

Continue readingThe complement system points to the heat-labile components of blood that contribute to the lysis of foreign pathogens that invade the blood
Continue readingT- Lymphocytes is a major class of lymphocytes whose precursors arise from the bone marrow then migrate and mature in the thymus of which they derive their name (Thymus derived lymphocytes). They are divided into functionally distinct populations which are T- helper cells (CD4+), cytotoxic cells (CD8+) and the T-regulatory cells (CD4+).

Antibodies are groups of proteins composed of between 82 to 96% polypeptide and 4 to 18% carbohydrate. They are present in the serum and tissue fluids of vertebrates. Some are curried on the cell surface where they act as receptors while others are free in the blood or lymph, referred to as the antibodies.
Continue readingThe major characteristics of acquired immunity include memory, specificity and recognition which makes it invaluable in protecting against recurrent infections.
Continue readingCytokine is a general name meaning ‘cell produce’. Cytokines are therefore small secreted proteins that mediate and regulate immunity, inflammation, and hematopoiesis normally produced due to an immune stimulus.
