    Animal Cells Red Blood Cells Red Blood Cells (RBCs) are also known as erythrocytes. There are up to 4.2 - 6.2 million RBCs in a cubic millimetre of blood. They specialize in transporting oxygen around the body. As a result of this RBCs are small and have a biconcave shape to increase their surface are to optimize the amount of oxygen that diffuses across their cell membrane. As well as this RBCs have no organelles other than a cell membrane and cytoskeleton (in mammalian RBCs). After oxygen

    Sickle Cell Anemia and Red Blood Cell Physiology Introduction Sickle cell anemia is a disorder in which the body makes crescent-shaped red blood cells. Normal red blood cells are disc-shaped. They move easily through your blood vessels and contain an iron rich protein called hemoglobin. This protein carries oxygen from the lungs to the rest of the body. Sickle cells contain abnormal hemoglobin due to a mutation in the hemoglobin chain. This type of hemoglobin is known as sickle hemoglobin or

    other words, the plasma membrane is semi-permeable that it allows nutrients to enter the cell but keeps out undesirable substances. This property allows the cell to segregate its inner cytoplasm from the external environment. There are two different ways to pass though this membrane: active and passive transport. Active and passive transport are both biological process that move oxygen, water and nutrients into cells and remove waste products; however, these two processes happen in a different mechanism

    molar concentrations of non-penetrating moles for sheep red blood cells and measured the absorbance levels from each concentration. The results concluded that as the concentration increased the absorbance reading increased as well. A higher absorbance signifies higher amounts of intact RBCs. The isotonic molar concentration for NaCl and glucose is 0.3 M. The hemolysis molar concentration for NaCl and glucose is 0.05 M. Adding red blood cells to an isotonic solution, there will be no isotonic pressure
