vérplazma
Vérplazma is the pale‑yellow liquid component of blood in which the blood cells are suspended. It makes up about 55% of total blood volume and is largely water (roughly 90–92%), containing dissolved proteins, electrolytes, nutrients, hormones, gases and waste products. In medical practice, plasma is obtained from blood collected with anticoagulants and separated by centrifugation; serum is the liquid left after coagulation and lacks fibrinogen and other coagulation factors.
Composition: The protein content of plasma includes albumin, globulins and fibrinogen. Albumin accounts for the largest
Functions: Plasma acts as the medium for transport of nutrients, hormones and waste products, and helps regulate
Clinical relevance: Plasma is used therapeutically to treat deficiencies of coagulation factors or proteins. Fresh frozen
Safety and storage: Donor plasma is screened for infectious agents and stored frozen, typically at −18°C or
