2. Compare the development of lymphocytes with other formed elements. B lymphocytes develop in red bone marrow‚ T lymphocytes develop in red bone marrow and mature in the thymus; the other formed elements develop in red bone marrow 3. What is erythropoiesis? Which factors speed up and slow down erythropoiesis? Erythropoiesis is the process by which red blood cells (erythrocytes) are produced.

LABORATORY REPORT RENAL PHYSIOLOGY INTRODUCTION: The kidneys‚ which maintain the purity and constancy of our internal fluids‚ are perfect examples of homeostatic organs. They regulate the chemical content the pH and osmotic pressure of the blood. Kidneys filter gallons of fluid from the bloodstream. They then process this filtrate‚ allowing wastes and excess ions to leave the body in urine while returning needed substances to the blood in just the right proportions. Factors that affect urine
