bloedsamenstelling

Bloedsamenstelling refers to the qualitative and quantitative makeup of blood. Blood is a fluid connective tissue composed of several key components. Plasma, the liquid matrix, constitutes about 55% of blood volume and is primarily water (about 92%). It also contains dissolved proteins like albumin, globulins, and fibrinogen, as well as electrolytes, hormones, nutrients (glucose, amino acids, lipids), and waste products (urea, carbon dioxide).

The remaining 45% of blood volume consists of cellular components, collectively known as the formed elements. These include erythrocytes, also called red blood cells, which are the most numerous cell type and are responsible for oxygen transport via hemoglobin. Leukocytes, or white blood cells, are part of the immune system and are involved in defending the body against infection and disease. There are several types of leukocytes, including neutrophils, lymphocytes, monocytes, eosinophils, and basophils, each with specialized functions.

Finally, thrombocytes, or platelets, are small, irregular cell fragments crucial for hemostasis, the process of blood clotting. They aggregate at sites of vascular injury to form a plug and release factors that initiate the coagulation cascade. The precise balance and number of these components are vital for maintaining overall health, and deviations from normal bloedsamenstelling can indicate various physiological or pathological conditions. Blood tests, such as a complete blood count (CBC), are commonly used to assess these components.
