The Correct Answer and Explanation is:
Here is the correct matching of plasma proteins to their functions:
- Albumin: Drives osmosis and helps maintain blood volume.
Explanation: Albumin is the most abundant plasma protein in the blood and plays a crucial role in maintaining oncotic pressure (the pressure exerted by proteins in the blood plasma that helps to retain fluid within blood vessels). By driving osmosis, albumin helps to prevent fluid from leaking out of the bloodstream into surrounding tissues. This function is essential for regulating blood volume and pressure. If albumin levels fall (due to liver disease or malnutrition, for example), it can lead to edema (swelling due to fluid accumulation). - Globulins: Some may be antibodies, aid in the transport of lipids.
Explanation: Globulins are a diverse group of proteins in the blood plasma that serve various functions. Some globulins, known as immunoglobulins or antibodies, are crucial for immune defense as they bind to and neutralize foreign invaders like bacteria and viruses. Other globulins (such as lipoproteins) are involved in transporting lipids (fats) through the bloodstream. Globulins also play a role in clotting and inflammation. - Fibrinogen: Functions in blood clotting.
Explanation: Fibrinogen is a soluble plasma protein produced by the liver that is essential for blood clotting. When an injury occurs and bleeding begins, fibrinogen is converted into fibrin, which forms a mesh-like structure that traps blood cells and platelets, creating a blood clot. This prevents excessive bleeding and promotes wound healing. Without fibrinogen, blood would not be able to clot properly, leading to excessive bleeding.
These plasma proteins are vital for maintaining homeostasis in the body, as they contribute to various processes such as immune defense, nutrient transport, and blood volume regulation. Their imbalance can lead to a variety of health issues, including immune deficiencies, edema, and bleeding disorders.
