What is the Fluid Part of Blood After Removal of Corpuscles? Understanding Blood Plasma

Blood, the vital fluid circulating throughout our bodies, is far more complex than just a simple liquid. It's a complex mixture of cells and a liquid component. When the cellular components – red blood cells (erythrocytes), white blood cells (leukocytes), and platelets (thrombocytes) – are removed, what remains is blood plasma. This article explores the composition and functions of this crucial fluid.

The fluid part of blood after the removal of corpuscles is plasma, a pale yellow, straw-colored liquid that constitutes roughly 55% of total blood volume. It's a complex solution containing a diverse array of proteins, electrolytes, nutrients, hormones, and waste products. Understanding its composition and functions is essential for grasping the intricacies of the circulatory system and overall health.

The Composition of Blood Plasma: A Complex Mixture

Plasma is primarily composed of water (approximately 90%), but its remaining 10% harbors a rich mix of substances crucial for maintaining homeostasis:

• Proteins: This is the most significant component besides water. Major plasma proteins include:
  • Albumin: Maintains osmotic pressure, preventing fluid leakage from blood vessels.
  • Globulins: Involved in immunity (immunoglobulins or antibodies) and transport of various substances.
  • Fibrinogen: Essential for blood clotting.
• Electrolytes: Minerals like sodium, potassium, calcium, chloride, and bicarbonate maintain proper fluid balance, nerve impulse transmission, and muscle contraction. Electrolyte imbalances can be life-threatening.
• Nutrients: Glucose, amino acids, lipids, and vitamins are transported to cells throughout the body for energy production and metabolic processes. Plasma provides the transport medium for these essential nutrients.
• Hormones: Chemical messengers produced by endocrine glands are carried by plasma to target tissues, regulating various bodily functions. Testing plasma hormone levels is crucial in diagnosing endocrine disorders.
• Waste Products: Metabolic byproducts like urea, creatinine, and uric acid are transported by plasma to the kidneys for excretion. Elevated levels of these waste products in plasma indicate potential kidney dysfunction.
• Gases: Oxygen and carbon dioxide are dissolved in plasma, playing crucial roles in respiration. Oxygen levels are measured via blood tests to assess respiratory function.

Functions of Blood Plasma: Maintaining Life's Balance

The diverse composition of blood plasma underpins its multifaceted functions:

• Transport: Plasma serves as the primary transport medium for nutrients, hormones, waste products, and gases throughout the body. It acts like a delivery system, ensuring essential components reach their destinations.
• Osmotic Balance: Albumin's contribution to osmotic pressure is critical in preventing fluid leakage from blood vessels. This helps maintain appropriate blood volume and pressure.
• Immune Response: Plasma contains antibodies and other immune proteins that play vital roles in defending the body against infection and disease.
• Blood Clotting: Fibrinogen is a key player in the coagulation cascade, initiating the process of blood clot formation to prevent excessive bleeding.
• Temperature Regulation: Plasma's high water content contributes to the body's ability to regulate its temperature.

Blood Plasma vs. Serum: What's the Difference?

It's important to differentiate between plasma and serum. Serum is the fluid remaining after blood clots. The key difference lies in the presence of fibrinogen: plasma contains fibrinogen, whereas serum does not, as fibrinogen is used up in the clotting process. Both are valuable in various medical tests, but their composition differs slightly.

In conclusion, the fluid part of blood after removal of corpuscles, blood plasma, is a complex and vital fluid with diverse functions. Its role in transport, osmotic balance, immune response, and blood clotting underscores its importance in maintaining homeostasis and overall health. Understanding its composition and functions provides valuable insight into the intricacies of the human body.
