@med_study_edu: Answer: A (Albumin) Here is the explanation: Albumin is a protein produced by the liver that helps maintain oncotic pressure (the pressure that keeps fluid within the blood vessels). A deficiency in albumin, often seen in conditions like nephrotic syndrome or liver cirrhosis, leads to a decrease in plasma osmotic pressure, allowing fluid to leak into tissues and cause pitting edema. This is the most common protein involved in oedema formation. B) Hemoglobin is the protein in red blood cells that carries oxygen. While anemia (low hemoglobin) can cause fatigue and pallor, it does not directly lead to pitting edema. C) Collagen is a structural protein in connective tissues, providing strength and elasticity to skin, tendons, and ligaments. Defects in collagen (e.g., Ehlers-Danlos syndrome) may cause skin laxity or joint hypermobility, but not pitting edema. D) Myosin is a motor protein involved in muscle contraction. While muscle disorders can lead to weakness, they do not affect fluid balance or oncotic pressure, meaning myosin deficiency does not cause pitting edema. #medicalnotes #medicine #trending
