검증된 단계별 안내1
Understand the composition of blood: Blood is composed of plasma and formed elements (red blood cells, white blood cells, and platelets).
Recognize that plasma is the liquid portion of blood, which carries cells, nutrients, hormones, and waste products.
Learn that in a healthy adult, plasma typically makes up about 55% of the total blood volume.
Consider the options given: 65%, 45%, 55%, and 35%. Identify which percentage aligns with the typical composition of plasma in blood.
Conclude that the correct percentage of plasma in whole blood is approximately 55%, based on standard physiological data.
