antigen
a substance that the body recognizes as foreign stimulating the immune system to release antibodies for defense
embolus
the breaking away of a thrombus from the vessels wall and floats freely in the bloodstream
tunica intima
the lining of the interior vessels made of endothelium (squamous epithelial cells) that form a slick surfact that decreases friction as blood flows through the vessels lumen
monocytes
the largest of the WBC's resemble large lymphochytes ecept they have mroe cyotplsm and indented nucleus, they fight against chornic infections like tuberculosis
hypertension
abnormal high blood pressure
pulmonary edema
leakage of fluid into the air sacs and tissue of the lungs
antibody
the recognizers of antigens, foreign substances in the body
basophil
WBC with granules staind deep blue with basic dye, pale nucleus and granular appearing cytoplasm
thrombus
a clot the develops and persists in an unbroken blood vessel example clotting of an artery causing a heart attack
thromoytopenia
lack of enough circulating platelets
pulmonary conjestion
heart failure on the left side of the heart which is unable to eject the returning blood into the body
eosinophil
has a blue red nucleus and has large brick red cytoplasmic granules. increases during allergies and infections by parasitic worms
leukocytes
white blood cells and is primary function is to defend the body against disease
plasma
fluid portion of the blood
pericardial cavity
the space between the parietal pericardium and the epicardium
leukopenia
abnormal low WBC count caused by certain drugs like corticosteroids and anticancer agents
coagulation
blood clotting
coronary artery disease
the filling of the blood vessesl with fatty, calcified deposits
systole
is the contraction of the ventricles and is the top number 110-150 (normal range) of your blood pressure
cardiac output
the amount of blood pumped out by each side of the heart in 1 minute and is figured out by takeing the stroke volume times the heart rate
vasoconstriction
narrowing of blood vessels
bradycardia
heart rate slower than normal less than 60 beats per minute
thyroxine
hormones and ions that dramatically effect the heart activity such as increased heart rate
type B
when anti B serum is used on a slide and agglutination occurs what blood type is this person?
hematocrit
the percentage of erythrocytes, RBC's in a sample
platelet
irregular cell fragments of blood involved in clotting
agglutination
clumping of RBC's
arteriosclerosis
is the more general term to describe hardening or loss of elasticity of arteries and arterioles Arterio is Greek for artery, sclerosis means tough or hard.
pericardium
the heart is enclosed by a double sac of serous memberane called?
fibrillation
a rapid uncoordinated shuddering of the heart muscles and is a major cause of death from heart attacks in adults
hematopoiesis
blood cell formation occurs in red bone marrow, tissue found mainly in the flat bones of skull and pelvis, ribs, sternum and priximal epiphyses of the humerus and femur
myocardial infarction
heart attack
congestive heart failure
weakening of the heart by clogging of the coronary vessels with fatty buildup, constant high blood pressue or multiple non contacting scar tissue
purkinje fibers
Relays cardiac impulses to the ventricular cells causing the ventricles to contract.
ventricles
the lower discharging chambers of the heart that makes the heart pump
chordae tendineae
are tendinous cords that anchor the flaps to the walls of the ventricles
stroke volume
the volume of blood pumped from each ventrical with each contraction
pulmonary circuit
carries blood to the lungs for gas exchange and then returns it to the heart
diastole
is the relaxation of the ventricles and is the bottom number 60-80 (normal range) of your blood pressure
hemoglobin
iron bearing protein transports oxygen in erythrocytes RBC's
vasodilation
relaxation of the smooth muscles of blood vessels producing dilation
type A
when anti A serum is used on a slide and agglutination occurs what blood type is this person?
lymphocytes
large dark purple nucleus that take up most of the cell volume, a little larger than RBC's, reside in lymphatic tissues playing a role in the immune system
atherosclerosis
is a hardening of an artery specifically due to a plaque - a clot of lipid buildup (Lipoprotein cholesterol LDL the bad cholesterol). can be considered a form of arteriosclerosis.
formed elements
living blood cells
parietal pericardium
the anchor of the heart wall keeping the heart in place
tachycardia
rapid heart rate over 100 beats per minute
type O
contains not antigens and not agglutination occurs what blood type is this person?
sinoatrial node
it is cresent shape and starts each heartbeat and sets the pace for the whole heart
epicardium
tightly hugs the external surface of the heart and is actually part of the heart wall, it is also known as visceral pericardium
tunica media
the bulky middle coat of a blood vessel, it is smooth muscle and elastic tissue and changes the diameter of the vessels
type AB
when anti A and B serum is used on a slice and agglutination occurs what blood type is this person?
neutrophils
multilobed nucleus very find granules respond to both acid and basic stains, stains pink, and they are avid phagocytes
hypotension
low blood pressure
anemia
low oxygen carring capacity of the blood
buffy coat
whitish layer between the formed elements and the plasma
erythrocytes
red blood cells its primary function is to bring oxygen in the blood to all cells of the body
valves
allows blood to flow in only one direction through the heart chambers from the atria to the ventricles and out the great arteries leaving the heart
aorta
carries and distributes oxygen rich blood to all arteries and is the largest artery in the body
tunica externa
the outer most tunic made of fibrous connective tissue and is basically to suppor and protect the vessels
leukocytosis
the indicator that a bacterial or viral infectionis stewing in the body
systemic curcuit
supplies oxygen and nutrient rich blood to all body organs its walls are thicker due to distance it travels and the pump action is stronger
