1. What is the most abundant class of plasma protein?
a. Globulin c. Clotting factors
b. Albumin d. Complement proteins
2. What is the effect of low plasma albumin?
a. Clotting factors decrease, thus increasing the chance of prolonged bleeding.
b. Fewer immunoglobulins are synthesized, thus impairing the immune function.
