In biology, plasma refers to the liquid component of blood, which is a straw-colored, clear fluid that constitutes about 55% of total blood volume. It serves as the medium for transporting nutrients, hormones, and waste products throughout the body. Plasma is predominantly water, making up about 90% of its composition, but it also contains vital proteins such as albumin, globulins, and fibrinogen, as well as electrolytes, glucose, and various other substances. These proteins play crucial roles in maintaining osmotic pressure, immune responses, and blood clotting. Plasma facilitates the efficient exchange of materials between cells and tissues, supporting homeostasis and the overall functionality of the circulatory system.
Transportation: Plasma acts as the primary carrier for essential substances within the body. It transports nutrients for energy and growth, removes waste products for excretion, and carries hormones, facilitating communication between different organs and tissues.
Regulation: By maintaining the volume and composition of blood, plasma plays a crucial role in regulating blood pressure and ensuring consistent body temperature, thereby contributing to the body’s homeostatic balance.
Protection: Plasma contains antibodies and clotting factors, like fibrinogen, which are vital for the immune response and wound healing. These components help the body defend against pathogens and prevent excessive blood loss during injuries.
Osmotic Balance: Plasma proteins, particularly albumin, are essential in maintaining osmotic pressure, which controls the flow of water and solutes between blood and tissues, ensuring cells remain hydrated and functional.

Water, the primary constituent of plasma, accounts for about 90-92% of its volume. This high water content is essential for dissolving and transporting various substances throughout the body. Water in plasma:
Distributes Nutrients: It transports nutrients from the digestive system to cells.
Removes Waste: It helps transport waste products to the kidneys, liver, and lungs for excretion.
Regulates Temperature: It distributes heat throughout the body, maintaining a stable internal temperature.
Plasma proteins, comprising 6-8% of the plasma, play pivotal roles in various bodily functions. The liver primarily produces these proteins, which include:
Albumin: As the most abundant plasma protein, albumin maintains the osmotic pressure, which keeps fluid in the bloodstream and supports the transport of substances like hormones and drugs.
Globulins: These proteins, subdivided into alpha, beta, and gamma globulins, transport lipids and fat-soluble vitamins. Gamma globulins are particularly important as antibodies in the immune response.
Fibrinogen: This protein is key to blood coagulation. Upon injury, the body converts fibrinogen into fibrin, forming a clot to prevent excessive bleeding.
Electrolytes in plasma, including sodium, potassium, calcium, magnesium, chloride, bicarbonate, and phosphate ions, play vital roles in:
Balancing Fluids: They regulate the body’s fluid levels and pH balance.
Functioning Muscles: They are essential for muscle contractions, including the heartbeat.
