APPLIED RADIOLOGICAL ANATOMY

Detailed explanation-1: -About 50 proteins make up your body’s complement system. These proteins circulate throughout your blood and tissues.

Detailed explanation-2: -Abstract. The complement system consists of over 30 soluble and membrane-associated proteins. Complement was initially viewed as an arm of innate immune defenses against invading pathogens by marking them for elimination by professional phagocytes or by direct killing through pore formation.

Detailed explanation-3: -About 50 proteins and protein fragments make up the complement system, including serum proteins, and cell membrane receptors. They account for about 10% of the globulin fraction of blood serum.

Detailed explanation-4: -A system of plasma proteins that can be activated directly by pathogens or indirectly by pathogen-bound antibody, leading to a cascade of reactions that occurs on the surface of pathogens and generates active components with various effector functions.
