Isaac Medina Per 2 Cardiovascular System
Major components and functions of Blood
Red Blood Cells
Carry oxygen and carbon dioxide
White Blood Cells
Part of immune system and function in immune response
Platelets
Responsible for blood clotting
Plasma (55%):
ABO, RH blood types
A RhD positive(A+)
A RhD negative (A-)
B Rhd positive (B+)
B RhD negative (B-)
O RhD positive (O+)
O RhD negative (O-)
Major functions of the cardiovascular system
Delivers Oxygen
Nutrients
Hormones
Helps the body meet the demands of activity, exercise, and stress.
Anatomy of the Heart
4 Chambers
Upper chambers
Left/Right Atria
Lower chambers
Left/Right Ventricles
A wall of Muscle called the Septum separates the left and right atria/ventricles
Valves
Tricuspid
Between Right atrium and right ventricle
Pulmonary
Between right ventricle and pulmonary artery
Mitral
Between Left atrium and left ventricle
Aortic
Between left ventricle and Aorta
Layers of the Heart
Epicardium
Outer layer that contains blood vessels
Myocardium
Middle layer composed of contractile tissues.
Endocardium
Innermost layer contains vessels and nerves
Blood flow through the Heart and Body
Aorta
Upper/Lower Body
Superior-Inferior Vena Cava
Right Atrium
Tricuspid
Right Ventricle
Pulmonary valve
Pulmonary trunk
R/L Lungs
Pulmonary Veins
Left Atrium
Mitral Valve
Left Ventricle
Aortic Valve
Structural and functional differences between blood vessel types
Arteries carry oxygenated blood and veins carry deoxygenated blood. Arteries have thick walls with muscle tissue. Veins have thinner walls and use valves to keep your blood flowing.Capillaries transport blood between Arteries and Veins.
Cardiac Cycle and the ECG
The cardiac cycle is the human heart from the beginning of one heartbeat to the beginning of the next
At every beat, the heart is depolarized to trigger its contraction. This electrical activity is transmitted throughout the body and can be picked up on the skin. The ECG machine records this activity via electrodes on the skin and displays it graphically.
Major Blood Vessels
Arteries
Carry blood away from your heart
Veins
Carry blood back toward your heart
Capillaries
The smallest blood vessel, connect arteries and veins
Vital Signs
Average adult BP while resting is between 90/60 mmHg and 120/80 mmHg. Breathing 12 to 18 breaths per minute pulse is 60 to 100 beats per minute.
Disorders of the Cardiovascular system
Myocardial Infarction (Heart Attack)
Occurs when blood flow to heart is blocked by a blood clot, obesity, or smoking. You will feel chest pain, dizziness, and sweating. Nitroglycerin, open heart surgery, or lifestyle changes can be used to treat it.
Peripheral Artery Disease
Arteries narrow and reduce blood flow to extremities. Limb trauma, smoking, or obesity are causes. Leg and arm pain, weak pulse, or hair loss are symptoms and can be treated by medication, bypass surgery, or a lifestyle change.
Cerebrovascular Accident (Stroke)
Blood flow to a portion of the brain is interrupted. Clogged arteries, aneurysm, and age could be causes. Severe headache, memory loss or loss of balance are symptoms and thrombolytics, blood thinners, or surgical intervention are treatment options.
Endocarditis and Myocarditis
Inflammation of the heart. Heart valve damage, recent injury, or allergic reaction to medication are causes. Chest pain, fatigue, or shortness of breath are symptoms and can be treated by antibiotics, medication, or reduced activities.
Congenital Heart Disease
Issue with heart structure and function present from birth. Tetralogy of fallot, aortic stenosis, or pulmonary stenosis are causes. Depending on condition it may cause death. Medication, surgical intervention, or some abnormalities may heal on one's own.
