The Cardiovascular System
Major Components of the Blood
White blood cells
White blood cells are responsible for protecting your immune system.
Red Blood Cells
Red blood cells are responsible for transporting oxygen to the body
Platelets
Platelets are responsible for clotting your blood in areas of damage such as a cut. it is used in order for protection from bleeding out.
Functions of the Cardiovascular System
The cardiovascular system transports nutrients, oxygen and hormones to the cells in the body.
Anatomy of the Heart and System
Blood, Heart, and Blood Vessels
Chambers and valves of the heart
4 Chambers
Right atrium
Right ventricle
Left atrium
Left ventricle
Valves of the heart
Tricuspid, pulmonary semi-lunar, bicuspid/mitral, aortic semi-lunar
Heart strings AKA Chordae Tendineae
Layers of the Heart :smiley:
Endocardium
inner layer
Myocardium
middle layer
Epicardium
outerlayer
Blood Flow :recycle: from top to bottom
Inferior and superior vena cava
Right atrium
Tricuspid to the right ventricle
pulmonary valve to pulmonary artery
lungs to the left atrium
bicuspid to the left ventricle
aortic valve to the aorta
common carotid, brachiocephlaic, subclavian
rest of the body
Major Arteries and Veins :star:
Arteries
Coronary artery
Right and left Coronary artery
left anterior descending
left circumflex
Veins
Veins of the right thorax
superior and inferior vena cava
veins of the left thorax
Different blood vessel types
Arteries
carry oxygenated blood
Veins
carry deoxygenated blood
Capillaries
transfers oxygen and nutrients to the body
arterioles
little branches that lead to the capillaries
Venules
allows deoxygenated blood to return to the capillaires
intrinsic factors :red_flag:
variables that you are able to control to prevent yourself from injury
The Cardiac Cycle
The measure from an end of heartbeat to the beginning of a heartbeat
Two periods of the heart cycle
When the heart muscle relaxes
when the heart is filled with blood
the period of diastole and robust contractions
electrocardiogram :<3:
Measures the electric activity of your heart
measure the amount in order to ensure that the heart is working properly
Cardiovascular Disorders
Abnormal heart beats
Aorta DIsease
congenital heart disease
coronary artery disease
heart attacks
Heart muscle disease
Heart failure
