An anemia is normocytic when the red blood cells (RBCs) are of normal size. RBCs are normocytic when the mean corpuscular volume (MCV) is between 80 and 100 femtolitres (fL), which is within the normal and expected range. However, the hematocrit and hemoglobin are decreased. [1]
In a healthy person, a red blood cell survives 90 to 120 days in the circulation, so about 1% of human red blood cells break down each day. [ 38 ] [ unreliable medical source? ] The spleen (part of the reticulo-endothelial system ) is the main organ that removes old and damaged RBCs from the circulation. [ 2 ]
Blood in stool looks different depending on how early it enters the digestive tract—and thus how much digestive action it has been exposed to—and how much there is. The term can refer either to melena, with a black appearance, typically originating from upper gastrointestinal bleeding; or to hematochezia, with a red color, typically originating from lower gastrointestinal bleeding.

Red blood cells (RBCs), referred to as erythrocytes (from Ancient Greek erythros 'red' and kytos 'hollow vessel', with -cyte translated as 'cell' in modern usage) in academia and medical publishing, also known as red cells, [1] erythroid cells, and rarely haematids, are the most common type of blood cell and the vertebrate's principal means of delivering oxygen (O 2) to the body tissues—via ...
Almost all vertebrate organisms have hemoglobin-containing cells in their blood, and with the exception of mammals, all of these red blood cells are nucleated. [1] In mammals, NRBCs occur in normal development as precursors to mature red blood cells in erythropoiesis, the process by which the body produces red blood cells.
As we said, if you’ve had a single bowel movement with pale or clay-colored stool, it is probably safe to wait and see if the next bowel movement appears normal. However, the following co ...
Carbonic anhydrase catalyzes the conversion of carbon dioxide and water into carbonic acid. This molecule breaks down into bicarbonate and hydrogen ions. This break down process occurs in red blood cells. Ultimately, the concentration of bicarbonate ions in the bloodstream affects the formation of the protein carbaminohemoglobin in the body. [11]
The hematocrit (/ h ɪ ˈ m æ t ə k r ɪ t /) (Ht or HCT), also known by several other names, is the volume percentage (vol%) of red blood cells (RBCs) in blood, [1] [2] measured as part of a blood test. [3] The measurement depends on the number and size of red blood cells. [3] It is normally 40.7–50.3% for males and 36.1–44.3% for ...
