anemia low red blood cell count where the red blood cells are not replenished
aorta large vessel that allows blood to flow out of the heart and back into systemic circulation
arrhythmia change in the heart's rate or rhythm
artery vessel that carries blood away from the heart
asytole heart stops contracting and heart failure occurs
atrial fibrillation A-fib, condition that occurs when the SA node or the pacemaker of the heart is not working
auscultation the procedure of listening to a body part
autoimmune disease animal's red blood cells are destroyed by the immune system
AV valve opens and closes between the atrium and ventricle to allow blood to flow through each chamber of the heart
band cell immature neutrophil that indicates an infection within the body, shaped like a U
basophil white blood cell with a segmented nucleaus and granules that stain very dark and aid in allergic reactions
blood red liquid within the circulatory system that contains 40% of the cells in the body and transports oxygen
blood pressure (BP) the heart's contractions and relations as blood flows through the chambers
bradycardia heart beating slower than normal
cardiac arrest the heart is not contracting appropriately
centrifuge piece of equipment that uses high speeds to separate liquid portions from solids
circulatory system body system essential for life that includes the heart, blood, veins, arteries, and capillaries with the functions that include oxygen flow, blood circulation, and transport of nutrients, waste removal, and the movement of hormones
clot formation of a plug in the blood to stop bleeding
diastole relaxation phase of blood pressure or the lower number which is normally lower
electrocardiogram (ECG or EKG) a machine that controls the electrical currents of the heart
electrocardiography the evaluation of the electrical currents of the heart through the use of machines
endocardium thin inner muscle layer of the heart
eosinophil white blood cells that fight against allergic reactions, controlls inflammation, and protects the body from parasite infection and have a large nucleus with segmented granules within the cytoplasm
epicardium outer thin covering of the myocardium
erthyrocytes veterinary term for red blood cells
erthyropoiesis the production process of red blood cells within the bone marrow
fibrinogen protein that aids in clotting blood
globulin provide antibodies to help prevent disease
heart organ with four chambers located in the chest between the lungs
heart murmur an abnormal valve that produces an abnormal flow of blood that creates a swishing noise
heart rate pumping action of the blood through the heart creating a swishing noise upon auscultation
hemotology the study of blood
hemoglobin main component of red blood cells that allows oxygen transport and produces iron to allow cells to multiply
histamine chemical released during an allergic reaction
left atrium thin walled chamber of the heart that passes from the pulmonary artery into the left side of the heart
left ventricle thickest walled chamber of the heart
leukocytes veterinary term for white blood cells
lymphocytes white blood cells that make up the largest part of the bloodstream and aid in immune functions that protect the body from disease, have one large single nucleus that makes up most of the cell
macrophage cells that eat and destroy organisms throughout the body
monocyte largest white blood cell that help neutrophils rid the body of waste and cell debris
myocardium thick muscle that forms the wall of the heart
neutrophil most common white blood cell that destroys microorganisms within tissues that has a nucleus with segments
pacemaker system of the heart that controls heart sounds wand rhythm
pericardium thin membrane that covers, protects, and maintains the beating action of the heart
plasma formed of various proteins in the body and consists of 60% of the blood system, forms a solid portion of the blood
platelet blood cell used to clot blood by constricting vessel to stop bleeding
pulmonary artery carry oxygen poor blood and prevent blood flow back to the heart
pulse the heart rate of an animal or each beat created from the heart
P wave first peak on an EKG that forms at the SA node and reflects the flow of the electricity and blood through the atrium and a contraction has occurred
QRS complex series of peaks that show the electrical current and blood have flowed throug hthe AV node and have caused a contraction of the ventricles
red blood cells (RBC) most abundand cell in the body that are produced in the bone marrow and transport oxygen
repolarize reset or restart the heart and means to get ready for the next electrical impulse to start
right atrium thin walled chamber of the heart where blood enters
right ventricle thicker walled chamber of the heart where blood enters
SA node the term for the pacemaker of the heart
serum liquid portion of blood
shock condition that occurs when an animal does not have enough blood and oxygen reaching the tissues
sinus rhythm a normal heart rate and sound
stethoscope instrument used to listen to the heart, lungs, and chest
systemic circulation blood system that delivers nutrients and oxygen to all areas of the body
systole contraction phase of blood pressure or the top number that is usually higher
tachycardia heart beating faster than normal
thrombocyte veterinary term for platelets
T wave lask peak and the most important part of the EKG, shows that the electrical impulse has traveled through the entire heart and has completed the contraction and repolarized the heart
vasoconstriction diamter of a vessel has increased as blood pressure decreases
vasodilation diameter of the vessels increase as blood pressure decreases
vein vessels that carry blood to the heart
vena cava large vessel that transports blood to the heart from systemic circulation
ventricular fibrillation V-fib, condition causing the ventricles to fire electrical currents rapidly and is the most serious cause of cardiac arrest
white blood cells (WBC) five types of blood cells that protect the body from infection and aid in immune system protection
