Effects of Tonicity on Cell Membrane Abstract The purpose of this experiment was to determine the effects of tonicity on a cell membrane using red blood cells‚ potato strips and three unknown solutions (A‚ B‚ C). First three slides were prepared containing RBC’s and unknown solutions A‚ B and C. A control slide was prepared only using RBC’s. After observing each slide under the microscope it was determined that unknown solution A was hypertonic because the RBC appeared to have shrunk. The

Types of Solutions that Cells May Be Found In 1) Hypotonic Low [solutes] in ECF 2) Isotonic solution equilibrium 3) Hypertonic High [solutes] in ECF Oct 199:29 AM 1 Physiology Ch 3 Types of Solutions.notebook October 22‚ 2013 Hypotonic Low [solutes] in ECF In this situation‚ water wants to move from the ECF to the inside of the cell since there is a lower [H2O] inside than out. Particles (solutes) want to move out of the cell to the ECF since there is a

purpose of this experiment was to test the tonicity of potato cells. The potato cells were placed in different test tubes with water and were left there for 15 minutes. The percent change in mass is then used to determine if the cells lost or gained water‚ therefore determining the tonicity of the cell. Although it was a brief short time‚ the final results showed that the more water the potatoes were placed in‚ the more hypotonic the potato becomes. Tonicity is stated to be the state of a solution

Blood Cells Leukocytes (WBC’s) Leukocytes also known as white blood cells (WBCs) are cells which play a defensive roll in the body against injury and infection. They migrate towards tissues where they are needed and become functional performing various activities. WBCs can be divided into 2 groups: Polymorphonuclear granulocytes and mononuclear agranulocytes. Both types are spherical while suspended in blood plasma but when they invade tissues after leaving the blood vessels they become amoeboid

Blood Lab Report Introduction A blood experiment was performed testing four different patients blood to find out their specific blood types. Blood types are categorized in four blood groups based upon the antigen ( proteins on the surface of blood cells that can cause a response from the immune system) ("Rh factor" 2006) on the surface of the red blood cell. The blood groups are A‚ B‚ AB and O‚ names which are broken down from the ABO blood group system. Although simulated blood was used

White blood cell (WBC)—A white blood cell is one of the three main types of blood cells. They are produced in the bone marrow and released into the blood. White blood cells are responsible for fighting infection. There are several kinds of white blood cells‚ including monocytes‚ lymphocytes‚ neutrophils‚ eosinophils‚ and basophils. White blood cells‚ or leukocytes (also spelled "leucocytes"; from the Greek word leuko- meaning "white")‚ are cells of the immune system involved in defending the body

Lindsay Turner 4/20/01 White Blood Cells Bacteria exist everywhere in the environment and have continuous access to the body through the mouth‚ nose and pores of skin. Further more‚ many cells age and die daily and their remains must be removed‚ this is where the white blood cell plays its role. According to this quotation‚ without white blood cells‚ also known as leukocytes‚ we would not be able to survive. White blood cells are our body ’s number one defense against infections. They

or system is the white blood cells. The White Blood Cells work to fight off any infection there is and have a memory function that remembers the disease to keep it away. A leukocyte‚ which is the formal name for white blood cells‚ protects the body in various ways from getting sick. The red bone marrow’s stem cells‚ which are called hemocytoblasts‚ are the source of creation for almost all of the white blood cells. Five types of white blood are carried through the blood to the sites of infection

Hello‚they call me Blue‚cause well I’m a carbon dioxide infused blood cell‚isn’t everybody?. I was made in the bone marrow along with all my brothers and sisters. Todays my 1st in the heart‚ and well I guess my first day to be alive really‚ I’m so excited. The heart would be my first trip well‚ anywhere really it’s truly amazing wait‚ unless you count the bone marrow. Did you know? I was only made about 5 seconds ago in your own bone marrow and now I’m headed for you’r heart. Okay so I’ll admit
