Systemic Circuit
-heart
-brain
-skeletal muscle
-kidney
-Liver GI
-skin
Pulmonary
100% to the lungs
what is the pathway of the blood?
rt atrium-right ventricle-artery-lungs-veins-left atrium-left ventricle-artery-all body tissue vein
What iniatiates each heart beat?
S.A. Node- pacemaker determines how fast/slow your heart beats
Blood pressure
systolic-higher number
-diastolic-the lower number, when the ventricles aren't contracting
Cardiovascular Diseases
Hypertension-can lead to Atherosclerosis
Atherosclerosis-can lead to more, platelets build up
-Cornary artery disease (CAD)
Hypertension
-slient killer
-heart works harder
-damage to blood vessels
Athensclerosis
-Build up of lipids in artery walls=plaques
-can narrow artery or can rupture
-can result in heart attacks or strokes
Cornary Atery Disease(CAD)
-Atherosclerosis in cornary arteries
-chest pain
-Treatment can be drugs or surgery
heart Attack(Myocardial Infarction)
-Heart tissue dies
-scar tissue forms
-piece of plaque breaks off
-more quickly the better your chance
-lack of oxygen then tissue dies
