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?1 Approximately two-third of the iron in the body is stored in hemoglobin. The Surplus iron that is not available directly in the blood is stored in the iron-storing proteins known as ferritin. When dietary iron has been plentiful‚ ferritin is constantly and rapidly made and broken down‚ providing

yellow pigment which is seen on your skin is due to bilirubin which is a byproduct of old red blood cells. If you are affected by jaundice consider it to be a serious problem which cannot to be taken lightly. Nearly 1% red blood cells retire everyday and those are replaced by fresh blood cells. These old blood cells are processed in the liver and later disposed. If there happens to be too many old red blood cells the yellow pigment builds up in the body‚ which results in the first stages of jaundice

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

people with sickle cell anemia survive to mid-40’s although fewer than 10% live more than 60 years. The devastating thong about anemia is that it can be inherited and with no cure‚ the cases of Anemia are increasing. Even though there is no cure‚ early diagnosis of low blood count can lead to better treatment‚ with better treatment‚ patients can live normal lives. However‚ the key to early diagnosis is learning what anemia is and the causes of this blood disease. Anemia is a blood disease in which

What are the components of blood? The components of blood are plasma‚ platelets‚ red blood cells‚ and white blood cells. (Vass‚ 2007 pg. 63) B. What are the functions of red blood cells?

B cells belong to a group of white blood cells known as lymphocytes‚ making them a vital part of the immune system The human body makes millions of different types of B cells each day that circulate in the blood and lymphatic system performing the role of immune surveillance. They do not produce antibodiesuntil they become fully activated. Each B cell has a unique receptor protein (referred to as the B cell receptor (BCR)) on its surface that will bind to one particular antigen. If the pathogens are

ADI Lab Report Every living thing is made up of cells. All cells have some part in common. Some multicellular cells are highly specialized and carry out some very important functions. One of the special cells are red blood cells‚ their functions‚ transporting oxygen from the lungs to the cells in the body. Red blood cells look like little discs. Red blood cells can change their shape‚ this ability allowing them to squeeze through capillaries without breaking. Our task is to Design and carry out an

releases Oxygen to the body via the blood circulation. Hemoglobin is made of 4 polypeptide chains with each chain containing an iron-heme structure that contains the oxygen-binding site. Each hemoglobin molecule twists a polypeptide chain into a helical secondary structure. The helices drape around the heme group and form into a tertiary structure subunit. The four subunits are packed into a globular quaternary protein structure. The iron-heme structures give the red color to hemoglobin. Each hemoglobin
