What is the fluid part of the blood called?

Serum
Platelets
Plasma
Hemoglobin

The correct answer is: Plasma

The fluid part of the blood is referred to as plasma. Plasma makes up about 55% of total blood volume and is primarily composed of water, electrolytes, proteins, nutrients, hormones, and waste products. It serves several vital functions, including transporting nutrients and hormones to cells, removing waste products, and facilitating the immune response by carrying antibodies and other proteins. Serum is similar to plasma but is obtained after blood has clotted, meaning it does not contain clotting factors like fibrinogen. Platelets are cell fragments involved in blood clotting, and hemoglobin is the protein within red blood cells responsible for carrying oxygen. Understanding the distinct roles of these components is important in the study of blood and its functions.
