Fluid composed of blood plasma minus certain macroproteins?
lymph
name the three types of granular leukocytes
neutrophils
eosinophils
basophils
An agent that causes dilation of the blood vessels
vasodilator
A common way to measure heart function. A graphic tracing of the variations of electrical potential caused by excitation. Attaches leads
electrocardiogram
Affixed to sites on the body in order to pick up electrical activity underneath?
electrodes
leukocytes are also called
white blood cells
examination of the segments along the left and right mediastinal borders
silhouette
radionuclide procedure which evaluates ventricular function and wall motion?
ventriculography
Obtained by dividing stroke volume by the end-diastolic volume?

leukocytes can be divided into two basic categories
granular and agranular
pumps blood into the aorta and into the systemic arteries
left ventricle
cellular portion of blood is composed of these
erythrocytes
leukocytes

right ventricle
left ventricle
right atrium
left atrium
Name the three different layers of the heart
epicardium
myocardium
endocardium
actual contraction of the heart chamber
systole
Where is the heart located?
in the chest (thoracic) cavity between the lungs in the mediastinum
