Eduardo Aguiar, Period 5 Cardiovascular
blood
components
plasma, the least dense in blood, mixture of water nutrients and waste
formed elements, cells including erythrocytes, leukocytes, and thrombocytes
erythrocytes, known as red blood cells which are the most dense in blood
-
-
anatomy of the heart
chambers in order
right atrium, right ventricle, left atrium, and left ventricle
valves in order
tricuspid valve, pulmonary semi-lunar valve, mitral valve, and aortic semi-lunar valve
layers
endocardium (inner layer), myocardium (middle layer), and epicardium (outer layer)
some exterior structures
has structures including interventricular sulcus, coronary artery, and cardiac veins
-
blood flow
-
-
-
-
from the lungs, blood goes into pulmonary veins and into the left atrium
-
-
from the aorta, blood is redistributed throughout the body to lose oxygen
-
blood vessel types
arteries
red vessels that carry blood away from the heart, which is oxygenated
-
capillaries
vessels that connect veins and arteries through several branches, are labeled as purple
disorders
endocarditis and myocarditis: inflammation of the heart, recent surgery is a cause, causes fatigue
myocardial infarction: heart attack where blood flow of the path towards the heart is blocked, can be from stress, causes heart palpitations
peripheral artery disease (PAD): when arteries narrow and reduce blood flow to extremities, caused by limb trauma, can lead to weak pulse and extremity pain
cerebrovascular accident: stroke where blood flow to the brain is blocked, can be from age, causes loos of coordination
congenital heart disease: issue with the heart structure that is present at birth, can be from tricuspid atresia, causes death
heart beat
-
cardiac cycle: blood flow through the heart in one complete heartbeat, first is atriole systole, then diastole, then ventricular systole or diastole
vital signs
temperature: can be taken using a thermometer, or taken manually to see if the patient is too hot or cold
-
blood pressure: taken by applying and slowly releasing pressure on the cuff (sphygmomanometer) and listening ofr systolic and diastolic beats
