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 |
|
|
LDL
|
-low density
-bad cholsterol (<130) |
|
|
HDL
|
-good cholesterol (>40)
|
|
|
Stroke
|
-brain tissue death
-results from a blood clot or rupture of blood vesscles |
|
|
Prokaryotic
|
-no nucleus
-no mitochondria -1 chromosome -no membrane bound organelles -cell walls -PLASID -smaller ribsomes |
|
|
Eukaryotic
|
-nucleus
-cell membrane -mitochondria -no chromosomes -membrane bound organells -some have cell walls |
|
|
Bacteria
|
-prokaryotic
-unicellular -mostly extracellular -most have cell walls -plasmids -often in groups(Biofilms) |
|
|

|
|
capsules
|
-outside of the cell
-more disease causing |
|
|
