Discussion 
 The experiment tested Ovis aries RBC tonicity in varying concentrated solutions. As 
more solutes occupied the solutions, each solution became increasingly hyperosmotic in 
comparison to the RBC’s. The hypothesis of this experiment was that, if the red blood cells are 
placed in contact with NaCl solution, then the degree of hemolysis of the red blood cells should 
be greater, due to the movement of water by osmosis. Figures 1 and 2 in the results section 
demonstrates; as the NaC...

Introduction 
Red blood cells (erythrocytes) are the most common type of blood cells and the 
vertebrate’s primary means of delivering oxygen to the cells of the body through the blood. The 
cells are composed of hemoglobin, a molecule that binds to oxygen and also carries some of the 
carbon dioxide produced in the tissue back to the lungs. The red color of erythrocytes is also the 
result of hemoglobin, which consists of iron and protein; increase or decrease in the 
concentration of hemoglo...
