Term | Definition |
---|---|
Refractometer | Used to measure the refractive index of a solution. Also known as "Total Solids Meter". |
Oblique | At an angle, or pertaining to an angle. |
Epaxial muscles | Support the spine, extends the vertebral column, allows lateral flexion. |
Hemolysis | Rupture of red blood cells. |
Plasma | Fluid portion of blood. 90-92% water. |
Triceps Brachii muscles | Extends the elbow joint. |
Biceps Brachii muscles | Flexes the elbow joint. |
Serum | Plasma, minus the clotting factors fibrinogen & prothrombin. |
Neutrophil | Protects the body against disease & infections by removing & destroying some types of bacteria, wastes, foreign substances, and other cells by eating them. Main type of white blood cell. Inflammation of tissues causes high Neutrophil in blood. |
Lymphocyte | Responsible for immune responses. Known as natural killer cells. Distinguishes healthy cells from cancerous cells. Two main types, B-cells and T-cells. |
Systole | Heart muscle contracts; blood is ejected from the atria to the ventricles, then from the ventricles to the arteries. |
Diastole | Heart relaxes & refills with blood to be ejected during the next systolic contraction. |
Poloarization | Process of generating electrical impulse from the SA node. Contraction of the heart. (Systole) |
Depolarization | Relaxation & refilling of the heart. (Diastole) |
Monocyte | Main job is to eat intruders. Responds to inflammation signals. Matures into macrophages (Greek for "large eaters). |
Eosinophil | Combats infections & parasites. |
Myocardium | Located inside the sac formed by the pericardium. Is the thickest layer of the heart. |
Pericardium | Outer layer of the heart. |
Endocardium | Membranous lining between myocardium and the heart chambers. |
Arteries | Carry oxygenated blood away from the heart. Blood is under high pressure. Walls of arteries are thick & elastic to allow expansion. |
Veins | Carry blood towards the heart. Thin walls. They also contain one-way valves to prevent blood from backing up. |
Basophil | Contains heparin and histamine. Deposits granules into damaged tissue to promote blood flow and inflammation. |
Thrombocytes | "Platelet". Cytoplasmic fragment of bone marrow megakaryocyte. |
Agglutination | Clumping of red blood cells. |
Rouleaux | Arrangement of erythrocytes in a column or stack. |
Tricuspid valve | Between the right atrium & right ventricle of the heart. Prevents blood from flowing backwards into right atrium. |
Mitral valve | Between the left atrium & left ventricle. Prevents blood from flowing backwards into left atrium. Also called "bicuspid valve". |
Sinoatrial valve | Pacemaker of the heart. Located in the right atrium of the heart. |
Lymph | Clear, transparent, colour-less fluid found in lymphatic vessels & cistema chyli. |
Colostrum | Initial mammary secretion after parturition. |
Active immunity | Refers to animals production of antibodies as a result of infection with an antigen or immunization. |
Passive immunity | Immunity that results when they receive protective substances produced by another human or animal. Passed from mother to newborn. |
Myo- | Muscle |
Hem/o Hemat/o | Blood |
Vas/o | Vessel; Duct; Vas deferens |
Pulmo Pulmon/o | Lung |
-emia | Blood conditon |
Myocardial infarction | Partial or complete occlusion or closing of one or more coronary arteries. "heart attack". |
Anemia | Reduction in the oxygen-carrying capacity of blood, caused by a reduced number of circulating red blood cells, reduced concentration of hemoglobin. |
Cardiomyopathy | Disease of the myocardium. Caused by alcohol abuse, parasites, viral infection & congestive heart failure. |
Canine autoimmune hemolytic anemia | An immune system disease in which the body attacks and destroys its own red blood cells. "AIHA" |
Von Willebrands Disease | Most common hereditary bleeding disorder. "vWD" |
