Cardiovascular System
Kaylee Lopez period: 2
Major components and functions of Blood
Plasma
: The functions of the plasma is to take nutrients, hormones, and proteins to the parts of the body that need it.
Red Blood Cells
: The function of the red blood cells is to deliver oxygen to the tissues of your body.
White Blood Cells:
To destroy pathogenic microorgainsm and parasites and also remove worn cells.
Platelets
: The function of the Platelets is to form clots when you have a wound to prevent it from bleeding.
Major functions of the cardiovascular system
1
. It helps transport the nutrients, waste products and gases around the body.
2
. It helps protect and fight off the body from infections and it also helps prevent blood loss.
3.
It maintains the body in a normal or constant body temperature.
4.
It maintain the bodies fluid in balance within the body.
Anatomy of the Heart
Chambers
: The upper chambers are the left and right atria and the bottom chambers are called right and left ventricles.
Valves:
The valves is the aorta, pulmonary valve, pulmonary trunk, aortic valve, left atrium, right atrium, mitral valve, left ventricle, tricuspid valve, and the right ventricle.
Layers of the heart
Epicardium:
It's a serous membrane the forms the innermost layer of the pericardium and the outer surface if the heart. It also surrounds the heart and its blood vessels.
Myocardium:
It's the muscular tissue of the heart and it makes the heart keep pumping blood around the whole body.
Endocardium:
It's the innnermost layer of the heart and it's a barrier between the cardiac muscle and the bloodstream.
Pericardium:
It's a sac/membrane the surrounds the heart. It helps keep the heart around the chest area and reduces the friction between hearts and the tissues that's around it.
Blood flow through the heart and body
1.
Superior vena cava/ inferior Vena cava
2.
Right atrium
3.
Tricuspid valve
4.

Aortic semilunar valve
13.
Aorta

Body tissues
Structural and functional differences between blood vessel types (arteries, veins,
capillaries)
The difference between the arteries, veins, and capillaries is the arteries transport blood away from the heart, the veins return the blood back to the heart, and the capillaries are thin blood vessels that connect the veins and arteries.
Major blood vessels (names arteries and veins)
Ascending Aorta:
It carries oxygen-rich blood from your heart to the rest of the aorta.
Aortic Arch:
It distributes blood to your head and upper extremities via.
Thoracic Aorta:
It provides blood to your muscle of the spinal cord and your chest wall
Abdominal Aorta:
It supplies oxygenated blood to some parts of your body
Disorders of the cardiovascular system
Coronary artery disease:
This happens when you have damaged or diseases in your hearts major blood vessels
High Blood Pressure:
This happens when the force of the blood is against the artery walls is too high.
Cardiac Arrest:
This happens when sudden lost function of the heart
Congestive heart failure:
It's a chronic condition of heart when it doesn't plump blood well as it should
Arrhythmia:
Its the improper beating of the heart when its going to fast or too slow.
Peripheral artery disease:
A condition when narrow blood vessels reduce blood flow to the limbs
Stroke:
It happen when the there is damage to the brain from interruption of its blood supply.
Congenital Heart Disease:
It's an abnormality in the heart the develops before the person is born.
Cardiac cycle and the ECG
P Wave:
It's atrial depolarization
QRS complex:
Ventricular depolarization
T wave:
Ventricular repolarization
U Wave:
Purkinje repolarizarion
