Kathy Ramirez Per. 2 Cardiovascular System
Major components and functions of Blood
red blood cell
transport oxygen from lungs to body cells
carry CO2 in returning trip
white blood cell
protect body from infection
types
basophils
monocytes
eosinophils
lymphocytes
neutrophils
plasma
transport blood cells throughout body
along with nutrients, waste products, antibodies etc
platelets
help blood clotting process
stick to lining of injured BV
platform where coagulation occurs
ABO, Rh blood types
B
AB
O
Pos
A
Neg
Major functions of the cardiovascular system
other substances to organs and body
meet demends of activity, stress, and exercise
deliver oxygen to body
Anatomy of the heart
Valves
tricuspid valve
aortic valve
pulmonary valve
bicuspid valve
blood vessels
arteries
veins
capillaries
left coronary artery
4 chambers
right ventricle
left atrium
right atrium
left ventricle
heart walls
myocardium
epicardium
endocardium
layers of heart
epicardium
myocardium
endocardium
blood flow through heart and body
right atrium
tricuspid valve
I/S vena cava
right ventricle
blood poor from body
pulmonary artery
lungs
pulmonary veins
left atrium
bicuspid valve
left ventricle
aortic valve
aorta
blood rich into body
Structural and functional differences between blood vessel types
veins
blood to heart
thin walls
large irregular lumen
low pressure
arteries
carry blood away from heart
thick walls
closer to heart
blood comes in at greater pressure
ECG
Q-T internal
start of ventricular depolarization
thru ventricuclar repolarization
S-T segment
ventricular myocardium depolarization
P-R Internal
start atrial excitation
start of VE
T wave
ventricular repolarization
QRS complex
ventricular depolarization
atrial repolarization
Major blood vessels
pulmonary trunk
pulmonary veins
vena cava
aorta
Vital signs
BP
90/60 mm Hg
120/80 mm Hg
Pulse
60 to 100 beats per min
disorders of the cardiovascular system
heart failure
blood not pumped well
stroke
heart attack
prolonged coronary blockage
loss of bf to heart
angina pectoris
cardiac cycle
systole phase
ventricles contract
blood from heart pumped to arteries
diastole phase
ventricle relaxes
heart filled with blood
