Anemia: People with anemia have a low number of red blood cells. Mild anemia often causes no symptoms. More severe anemia can cause fatigue‚ pale skin‚ and shortness of breath with exertion. Polycythemia vera: The body produces too many blood cells‚ from an unknown cause. The excess red blood cells usually create no problems but may cause blood clots in some people. Leukemia: A form of blood cancer in which a white blood cell becomes malignant and multiplies inside bone marrow. Leukemia may be

Infectious mononucleosis is caused by the Epstein-Barr virus (EBV). It is a double stranded DNA virus indistinguishable from other members of the herpes virus group. It get its’ name from the mononuclear (single nucleus) cells. It is also known as the "kissing disease"‚ because the most frequent mode of transmission is intimate salivary contact. It can also be transmitted from shared drinking and eating utensils‚ toothbrushes‚ etc. Mono is not likely to spread by aerosol (ex. sneezing) or fomites

process that generates all of our blood cells is called hematopoesis. This multistep process takes place mostly in the bone marrow. Hematopoiesis actually starts in embryonic development at a different site called the yolk sac‚ but at this early stage‚ only a few types of cells are generated. The process moves to other places‚ such as the fetal liver‚ but at birth‚ most hematopoiesis occurs in the bone marrow. At any given time‚ there is a hierarchy of cells in the bone marrow‚ each stage or

From a pathologic perspective‚ endometritis can be classified as acute versus chronic. Acute endometritis is distinguished by the presence of neutrophils within the endometrial glands. Chronic endometritis is characterized by the presence of plasma cells and lymphocytes within the endometrial stroma. Chronic endometritis in the postpartum or post abortion patient is usually associated with retained products of conception after delivery or abortion. In the nonobstetric population‚ chronic endometritis

What Are Thalassemias? Thalassemias (thal-a-SE-me-ahs) are inherited blood disorders. "Inherited" means that the disorder is passed from parents to children through genes. Thalassemias cause the body to make fewer healthy red blood cells and less hemoglobin (HEE-muh-glow-bin) than normal. Hemoglobin is an iron-rich protein in red blood cells. It carries oxygen to all parts of the body. Hemoglobin also carries carbon dioxide (a waste gas) from the body to the lungs‚ where it’s exhaled. People

our Mediaphys Lesson I learned that the primary structure of a cell membrane is made up of a double layer of phospholipids molecules. The hydrophilic heads of the phospholipid molecules face outwards towards the water base solutions inside and outside the cell. The membrane is also made up of proteins‚ carbohydrate molecules‚ and cholesterol that form gates and pores‚ cell recognition‚ and stability. Active transport is used when a cell needs a substance to cross the membrane against its concentration

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
