What is the fluid part of blood called?

The fluid part of blood is referred to as plasma. Plasma is a yellowish liquid that constitutes about 55% of the total blood volume. It serves several vital functions, including transporting nutrients, hormones, proteins, and waste products throughout the body. Plasma comprises water, electrolytes, and various proteins, such as albumin, globulins, and fibrinogen.

Understanding the role of plasma is important in various medical and health fields, including chiropractic care, as it plays a crucial role in maintaining overall health and facilitating healing processes. While serum is a component of blood that remains after coagulation and lacks clotting factors, it is not the primary fluid component in the context of the entire volume of blood. Hemoglobin is a protein within red blood cells responsible for oxygen transport, and the peritoneum is a membrane lining the abdominal cavity, unrelated to components of blood.
