blockage in the coronary artery due to plaque build up.
60 y/o woman w/ history of obesity and DM 2
pulmonary circulation
urinary system
mitral regurgitation
high blood pressure (pulmonary hypertension)
inadequate blood flow to extremities
increased blood pressure on the L. Atrium and veins coming from the lungs
fluid build up in lungs
nervous
risk of kidney damage
frequent urination; incontinence.
low RBC
inadequate blood flow to brain
dysautonomia; failure of the autonomic nervous system.

Left Atrium
bicuspid AV valve
Left Ventricle
Aortic SL valve
body
sup. and inf. vena cava
contracting to prevent prolapse during systole
respiration rate
blood pressure
circulation through the blood vessels
vital role in pumping the
blood throughout the body completely.
blood pressure goes down when heart relaxes
respiratory sinus arrythmia (RSA)
inhale: incr. HR
exhale: decr. HR
cardiac output
mean arterial pressure load
stroke volume
preload
heart rate
peripheral resistance
pulse
60-100 BPM
amount of blood pumped in one sitting
stroke volume X heart rate = cardiac output (4.7 L)
average blood pressure during one cardiac cycle
ventricular filling
afterload
resistance of arteries to blood flow
the force the heart has to eject blood against
R/L atria and R/L ventricles
valves
blood vessels
arteries, veins, and capillaries
Atroventricular Valve and Semilunar valve
lack of calcium; negative chronotropic drugs
