What is called the rupturing of erythrocytes?
Hemolysis. Heme (blood) + Lysis (to break apart)
Erythrocytes or red blood cells are formed in the bone marrow from precursor cells called erythroblasts which themselves are formed from pleuripotential stem cells - the mother of all blood cells. Along the way, erythroblasts take various forms/ stages until they differentiate into mature erythrocytes.
Blood is the serum, cells, platelets, and proteins, hormones, and chemicals that circulate in the blood stream. The cells that comprise blood include white blood cells and red blood cells. Red blood cells are also called erythrocytes, from the Greek erythros for "red" and cyte for "cell". Put another way, blood is the whole; erythrocytes are a part.
