Document Summary

Transportation: oxygen, nutrients, wastes, carbon dioxide, hormones and more. Regulatory functions: body temperature, water-salt balance and body ph. Formed elements: from cells produced in red bone marrow: red blood cells/erythrocytes (rbc) Transport oxygen: white blood cells/leukocytes (wbc) Defends the body against disease: platelets. Plasma: 92% water and 8% salts and organic molecules, is a medium for transporting materials in the blood. Blood cells come from your red bone marrow (epiphysis of long bones) The structure of red blood cells if important to their function lack a nucleus and few organelles biconcave shape increases surface area contain about 280 million hemoglobin molecules and each hemoglobin molecule binds. Rbc"s or hemoglobin that causes a run-down feeling. Sickle-cell anemia genetic disease that causes. Rbc"s to be sickle shaped that tend to rupture. Hemolytic disease of the newborn a condition with incompatible blood types that leads to rupturing of blood cells in a baby before and continuing after birth.
