cardiovascular system
Major components and functions of Blood
functions
it is in the heart, and blood vessels that make up the circulatory system
major components
white blood cells ( fights off infections), red blood cells (respiratory gas transport), plasma (liquid matrix), platelets (stoppage of bleeding)
Vital signs
blood pressure
move blood through arteries and arterioles. refers to systematic arterial pressure
pulse
when the ventricles contract and relax can be felt at certain points in the body .
pulse points : radial, carotid, bronchial and femoral arteries
Major functions of the cardiovascular system
transport blood into and around the body.
ABO, Rh blood types
type ab - b antigens and anti-a antibodies / universal recipient
type o no antigen on rbc membrane and both type of antibodies in plasma
type b - b antigen and anti-a antibodies
rh blood - if the rh factor is on the rbc membrane it is rh positive if no t then negative
type a - a antigens and anti-b antibodies
Blood flow through the heart and body
(starts) superior / inferior vena cava, right atrium, right ventricle, pulmonary trunk, lungs, pulonary veins, left atrium, left ventricle, aorta (end), cycle repeats
Cardiac cycle and the ECG
cardiac cycle
rise and fall pattern
systolic pressure : maximum arterial pressure
diatolic pressure : minimum arterial pressure
Layers of the heart
myocardium
middle layer that is made of cardiac muscle and pumps blood out of the heart chambers
endocardium
in inner most layer that is made up of connective tissues and epithelium
epicardium
outer most layer that is made up of connective tissues and the epithelium
Disorders of the cardiovascular system
if your heartbeat isnt even or lining up with what the heartrate graph gives then you can possibly get a pace maker to help keep your heart rate and beat at a constant pace and not an inconsistent one
Structural and functional differences between blood vessel types
arteries
transports blood away from the heart - thicker
capillaries
vessels that run between veins and arteries - medium
veins
transports blood toward the heart - very skinny
Major blood vessels
arteries
strong elastic vessels adapted for carrying high pressure blood. they become smaller as they divide and give rise to arteroles
veins
function as blood reservoirs, lead from capillaries merge to form larger veins that return blood to the heart
Anatomy of the heart
the heart is consists of 4 chambers. they are the left and right atrium and the left and right ventricles. There are 2 vena cavas (the inferior and superior) that help the blood flow back into the heart
