| ________is the consolidation or tightening of the fibrin clot that helps to bring the edges of a damaged vessel closer together. | Clot retraction |
| True or False: The attraction of phagocytes to microbes and inflamed tissue is termed chemotaxis. | TRUE |
| True or False: Leukopenia is an increase in white blood cell count that occurs during infection. | FALSE |
| Contain hemoglobin and function in gas transport | Red blood cells |
| Cell fragments enclosed by a piece of the cell membrane of megakaryocytes; contain clotting factors | Platelets |
| Individual forms of progenitor cells; named on the basis of the mature elements in blood they will ultimately produce | Colony-forming units |
| Monocytes that roam the tissues and gather at sites of infection or inflammation | Wandering macrophages |
| Give rise to red blood cells, monocytes, neutrophils, eosinophils, basophils, and platelets | Myeloid stem cells |
| Respond to tissue destruction by bacteria; release lysozyme, strong oxidants, and defensins | Neutrophils |
| Give rise to lymphocytes | Lymphoid stem cells |
| Cells no longer capable of replenishing themselves; can only give rise to more specific formed elements of blood | Progenitor cells |
| Hormone that stimulates formation of platelets | Thrombopoietin |
| Monocytes that leave the blood and reside in a particular tissue such as alveolar macrophages in the lungs | Fixed macrophages |
| Involved in inflammatory and allergic reactions; are involved in hypersensitivity reactions | Basophils |
| Stimulate white blood cell formation | Cytokines |
| Cells that give rise to all the formed elements of blood; derived from mesenchyme | Pluripotent stem cells |
| Tissue protein that leaks into the blood from cells outside blood vessels and initiates the formation of prothrombinase | Thromboplastin |
| An anticoagulant | Heparin |
| Platelet hormone that stimulates repair of damaged vessel walls | Platelet-derived growth factor |
| Glycoproteins and glycolipids on the surfaces of red blood cells that can act as antigens | Agglutinogens |
| The percentage of each type of white blood cell | Differential white blood cell count |
| Measures numbers of RBCs, WBCs, platelets per of blood; hematocrit; and differential WBC count | Complete blood count |
| Measures the rate of erythropoiesis | Reticulocyte count |
| Withdrawal of a small amount of red bone marrow with a fine needle and syringe | Bone marrow aspiration |
| Removal of a core of red bone marrow with a large needle | Bone marrow biopsy |
| Indicate if it causes vasoconstriction or vasodilation: hypercapnia | Vasoconstriction. |
| Indicate if it causes vasoconstriction or vasodilation: acidosis | Vasoconstriction. |
| Indicate if it causes vasoconstriction or vasodilation: ADH | Vasoconstriction. |
| Indicate if it causes vasoconstriction or vasodilation: hypoxia | Vasoconstriction. |
| Pressure generated by the pumping of the heart; pushes fluids out of capillaries | Blood hydrostatic pressure |
| Pressure created by proteins present in the interstitial fluid; pulls fluid out of capillaries | Interstitial fluid osmotic pressure |
| Balance of pressure; determines whether blood volume and interstitial fluid remain steady or change | Net filtration pressure |
| Force due to presence of plasma proteins; pulls fluid into capillaries from interstitial spaces | Blood colloid osmotic pressure |
| Pressure due to fluid in interstitial spaces; pushes fluid back into capillaries | Interstitial fluid hydrostatic pressure |
| Supplies blood to the kidney | Renal artery |
| Drains blood from the small intestine, portions of the large intestine, stomach, and pancreas | Superior mesenteric vein |
| Supply blood to the free lower limbs | Common iliac arteries |
| A rapid resting heart rate or pulse rate | Tachycardia |

| Becomes the ligamentum teres at birth | Umbilical vein |
| Become the medial umbilical ligaments at birth | Umbilical arteries |
| Passes blood from the fetus to the placenta | Umbilical arteries |
| Becomes the ligamentum venosum after birth | Ductus venosus |
| The highest force with which blood pushes against arterial walls as a result of ventricular contraction | Systolic blood pressure |
| A part of the venous circulation of the leg; a vessel used in heart bypass surgery | Great saphenous vein |
| Supplies blood to the large intestine | Inferior mesenteric artery |
| Drain blood from the head | Jugular veins |
| Detours venous blood from the gastrointestinal organs and spleen through the liver before it returns to the heart | Hepatic portal circulation |
| Drains most of the thorax and abdominal wall; can serve as a bypass for the inferior vena cava | Azygos veins |
| The lowest blood pressure in arteries during ventricular relaxation | Diastolic blood pressure |
| A slow resting heart rate or pulse rate | Bradycardia |
| Supply blood to the brain | Carotid arteries |
| Carry deoxygenated blood from the right ventricle to the lungs | Pulmonary arteries |
