Cardiovascular System Emmalise Fischer P.1
Major components and functions of Blood
Main components include plasma, red blood cells, white blood cells, and platelets
Blood transports oxygen and nutrients into lungs and tissues in body. White blood cells help fight infection and other diseases. Plasma helps your body recover from injury and contributes to 55% of bloods overall volume.
ABO, Rh blood types
Blood with proteins are Rh positive and without is negative.
AB negative is the rarest blood type
AB Positive blood means universal recipient. They can receive any one of the blood groups
Major functions of the cardiovascular system
delivers oxygen to lungs as well as nutrients, hormones, and others throughout the body,
Anatomy of the heart (including all chambers, and valves)
Chambers
Left atrium, Left ventricle, Right atrium, Right ventricle
Valves
Pulmonary semi lunar valve (between pulmonary artery and right ventricle)
Aortic semi lunar valve (between aorta and left ventricle)
tricuspit valve (between right atrium and right ventricle
Bicuspit valve (between left atrium and left ventricle)
Layers of the heart
Epicardium: Outer Myocardium: Middle Endocardium: Inner
Blood flow through the heart and body
Poor oxygenated blood enters the superior/inferior vena cava. Then it travels into the right atrium which then goes through the tricuspit valve to enter the right ventricle. Then the blood exits through the pulmonary semi lunar valve into the pulmonary trunk/ artery out the heart into the lungs where it picks up oxygen. The oxygenated blood enters the heart through the Pulmonary vein into the left atrium and then goes through the bicuspit valve to enter the left ventricle. Exiting the heart, the blood goes out the aortic semi lunar valve into the aorta. Then the blood drops oxygen throughout the body and begins the cycle again.
Structural and functional differences between blood vessel types (arteries, veins,
capillaries)
Arteries are the largest blood vessels with the thickest walls, capillaries are the smallest, and veins are used to transport blood into the body
Cardiac cycle and the ECG
The ventricular function 4 phases
isovolumic relaxation, ventricular filling, isovolumic contraction, and rapid ventricular ejection.
Major blood vessels (names arteries and veins)
Arteries
Aorta, Pulmonary artery
Veins
Superior/ Inferior vena cava, Pulmonary vein
Vital signs (BP and Pulse)
"normal" vital signs that show you are healthy range of blood pressure from 90/60 mm Hg to 120/80 mm Hg; Pulse: 60- 100 beats per minute
Disorders of the cardiovascular system
Myocardial infraction (Heart Attack): Blood flow blockage that is caused by blood clot, high blood pressure or stress. Includes chest pain, dizziness and arm pain.
Peripheral Artery Disease (PAD): Arteries narrow and reduce flow flow that is caused by blood vessel inflammation or limb trauma. Includes leg/arm pain and wounds that will not heal.
cerebrovascular Accident: blood flow to a portion of the brain is interrupted that is caused by blood clot in artery to the brain which includes headache and change in alertness.
Endocarditis and Myocarditis: Inflammation of the heart caused by virus, bacterial or fungal infection or recent surgery. Includes heart palpitations, chest pain and fatigue.
Congenital heart disease: Issue with heart structure and function that is caused by tetra-logy of fallot and aortic stenosis.
