as blood flows through peripheral tissues, what occurs regarding the hemoglobin molecules of RBC's?

thrombus

blood clot attached to the wall of a vessel is called

jaundice

condition from abnormally levels of high bilirubin in the plasma of the blood

through test of seeing which antigens it responds to

determining blood type

sickle cell

disease characterized by defective hemoglobin from mutation affecting the amino acid sequence of one pair of the globular proteins of the hemoglobin molecule resulting in stiff, markedly curved red blood cells

embolus

drifting blood clots, air bubbles, or fat globules are called
