Chapter 11: Blood
Study notes for Essentials of Human Anatomy and Physiology
| front | back |
|---|---|
| Normoblast | A red blood cell with a nusleus, an immature stage in red bllod cell formato usually found in the red bone marrow and not in the peripheal circulation. |
| Reticulocyte | A Blood cell that contains remnants of the endoplasmic reticulum, an immature stage in red blood cell formation; makes up about 1% of the red blood cells in peripheral circulation. |
| Rh Factor | The red blood cell types determined by the presence or absence of the Rh (D) antigen ont he red blood cell memebranes: the two types are Rh positive and Rh negitive |
| Thrombocyte | Platelet, a fragment of a megakaryocyte. |
| Thrombus | A blood clot that abstructs bllod flow through a bllod vessel |
| fibrin | A thread-like protein formed by the action of thrombin on fibrinogen; the substance in which blood clots are made |
| Hematocrit | The laboratory test that determines the percentage of red blood cells in a given volume of blood; part of a complete blood count |
| Hemophilia | A hereditary blood disorder characterized by the inability of the blood to clot normally; hemophilia A is caused by a la k of clotting factor 8 |
| RhoGam | trade mane for rh(d) administered toan rh negitive women who has delivered an RH positive infant |
| Extrinsic Factor | Vitamin B obtained from food and necessary for DNA synthesis, espically by stem cells in the red bone marrow |
| Inrinsic Factor | A chemical produced by the parietal cells of the gastric mucosa;necessary for the absorption of vitamin B12 |
| Pernicious Anemia | An anemia that is the result of a deficiency of vitamin B12 or the intrinsic factor |
| Fibrin | A thread-like protein formed by the action of thrombin on fibrinogen; the substance of which a clood clot is made. |
| ABO Group | The red blood cell types determined by the presence or absence of A and B antigens on the red blood cell membrane; The 4 types are A, B, AB, and O. |
| Albumin | A protien synthesized by the liver, which circulates in blood plasma. |
| Bilirubin | The bile pigment produced from the heme portion of the hemoglobin of old red blood cells. Excreted by the liver in bile. |
| Chemical clotting | A series of chemical reactions, stimulated by a rough surface or a break in a blood vessel, that result in the formation of a fibrin. |
| Embolism | Obstruction of a blood vessel by a blood clot or foreign substance that has traveled to and lodged in that vessel. |
| Erythrocyte | Red blood cell. |
| Hemoglobin | The protein in a red blood cell that contains iron and transports oxygen in the blood. |
| Homeostasis | The state in which the internal environment of the body remains relatively stable by responding appropriately to changes. |
| Heparin | A chemical that inhibits blood clotting, an anticoagulant. |
| Leukemia | Malignancy of blood-forming-tissues, in which large numbers of immature and nonfunctional white blood cells are produced. |
| Leukocytosis | An elevated white blood cell count, often an indication of infection. |
| Macophage | A phagocytic cell derived from monocytes that contributes to bouth innate and adaptive immunity |
| Rh Factor | The red blood cell types determined by the presence or absence of the Rh (D) antigen on the red blood cell membranes two types our Rh positive and Rh negitive |
