first describe the transmition of the disease and then the colonization that takes place. During a blood meal on a human a female mosquito must inject her saliva containing an anticoagulant agent to ensure and even flow of blood into the mouth (1). With the saliva comes malarial sporozoites which‚ within minutes of direct contact with the blood take an immediate route with the circulation of blood to the liver of the human (2). Research has indicated that once the sporozoites arrive in the livers

of but the transportation of oxygen and carbon dioxide by diffusion in human is insufficient‚ this distribution is enabled by a movement of fluid called blood‚ In effect human body use one molecule found in the red blood cell called haemoglobin‚ on the other hand the haemoglobin can be define as a molecule found in the red blood cell which deliver or transport oxygen to the rest of body muscles and tissues. In this our essay we are going to describe the chemical structure which form the

Human bloods have differences precisely to the presence or absence of certain protein molecules called antigens and antibodies. The antigens can be found on the surface of red blood cells and the antibodies are in the blood plasma. Individuals have different types and combination of these molecules. Blood group is like a trait which we inherit to our parents. The blood group you belong depends on what you have inherited from your parents. There are three types of antigens: A antigen‚ B antigen

iron in the center. It is the iron that binds the oxygen in a weak interaction that can easily broken. A RBC (red blood cell) is packed with haemoglobin molecules. The cell has no nucleus‚ so more haemoglobin molecules can be included. 2 Function of haemoglobin in Transporting Oxygen: * transport of O2 * transport of some CO2 from body cells to the lungs * conversion of CO2 to HCO3- by the action of the enzyme carbonic anhydrase in the RBC; HCO3- produces H+

and Physiology II Unit 5 Gas Exchange Explain how the gas laws and the properties of gases affect the gas exchange between the lung‚ blood‚ and tissues. The major function of the respiratory system is to provide the body with oxygen and rid the body of carbon dioxide. Gas exchange occurs between blood and alveolar air (external respiration) and between blood and tissues (internal respiration).Gas exchange process depends on properties of gasses. Based upon the Basic properties of Gases; Dalton’s

Introduction : Diffusion: In general‚ diffusion process occur when there is a concentration gradient between two region .Molecules (other than water) will move by diffusion as long as there is a concentration gradient. A concentration gradient

by iron in the transport of oxygen. The structure of hemoglobin is a hemi group. A hemi group consists of an iron (Fe) ion held in a heterocyclic ring. Iron binds with oxygen. Therefore‚ it has a very important role in transporting oxygen in the blood. How is iron stored and transported in the body? Iron can be stored within intestinal entrecotes bound to ferritin and transported transversely along the basolateral membrane of intestinal entrecotes. The liver is the chief storage site for iron

Membrane Abstract: Cell membranes play an important role in regulating what goes in and out of the cell. Diffusion‚ the process of movement of substances across the cell membrane from higher concentrations to areas of lower concentration‚ plays an active role in the transport and the regulation through cellular membrane. Sometimes‚ there are cases when cells are placed in hypotonic solutions and substances will diffuse through the cell membrane too much and will result the cell to hemolysis‚ causing
