The liquid that blood cells and nutrients are suspended in is called what?

• A. Sera
• B. Platelets
• C. Plasma
• D. Serum

Answer: (C)

The correct answer is plasma. Plasma is the liquid component of blood that serves as a medium for blood cells, nutrients, hormones, and waste products to be suspended and transported throughout the body. It constitutes about 55% of blood volume and plays a critical role in maintaining blood pressure and volume, supporting cell function, and transporting nutrients and waste products. Plasma contains proteins, such as albumin, globulins, and fibrinogen, which are essential for various bodily functions, including blood clotting and immune responses. Understanding the composition and function of plasma is vital for recognizing its role in various medical conditions and emergencies. In contrast, serum is the liquid that remains after blood has clotted, meaning it doesn't contain clotting factors. Sera refer to multiple samples of serum from different individuals. Platelets are a type of blood cell involved in clotting and are not a liquid. Understanding these distinctions reinforces the importance of plasma as the primary liquid medium in which vital blood components are suspended.
