Cardiovascular System
major functions of the cardiovascular system;
Major components of
blood,
Layers of the heart;
Anatomy of the heart (including all chambers,
and valves);
structural and functional differences between blood vessel types;
blood flow through the heart and body;
Major arteries and veins of
the body;
platelets
red blood cells
white blood cells
plasma
carries water, salts and enzymes. The main role of plasma is to take nutrients, hormones, and proteins to the parts of the body that need it. Cells also put their waste products into the plasma.
carry oxygen from the lungs to the body tissues and carbon dioxide as a waste product, away from the tissues and back to the lungs.
help your body form clots to stop bleeding
protecting the body against both infectious disease and foreign invaders
Transport of nutrients, oxygen, and hormones to cells throughout the body and removal of metabolic wastes (carbon dioxide, nitrogenous wastes).
Chambers
Valves
mitral valve and tricuspid valve, which control blood flow from the atria to the ventricles.
aortic valve and pulmonary valve, which control blood flow out of the ventricles.
two atria and two ventricles. ... The right ventricle pumps the oxygen-poor blood to the lungs. The left atrium receives oxygen-rich blood from the lungs and pumps it to the left ventricle. The left ventricle pumps the oxygen-rich blood to the body.
endocardium
epicardium
myocardium
Inner most layer of the heart
Outer most layer of the heart
In between the 2 layers
disorders of the cardiovascular system.
Abnormal heart rhythms, or arrhythmias.
Aorta disease and Marfan syndrome.
Congenital heart disease.
Coronary artery disease (narrowing of the arteries)
Deep vein thrombosis and pulmonary embolism.
Heart attack.
Heart failure.
heartbeat is irregular, too slow, or too fast.
aorta may become enlarged (aortic dilation) or the walls of the aorta may bulge (aortic aneurysm).
walls of the heart, the valves of the heart, and the arteries and veins near the heart.
blockage of the coronary arteries, usually caused by atherosclerosis.
when a blood clot called a deep vein thrombosis (DVT), often in your leg, travels to your lungs and blocks a blood vessel.
heart muscle caused by a loss of blood supply. The blood is usually cut off when an artery supplying the heart muscle is blocked by a blood clot.
heart can't pump enough blood to meet the body's needs. In some cases, the heart can't fill with enough blood. In other cases, the heart can't pump blood to the rest of the body with enough force.
Blood enters the heart through two large veins, the inferior and superior vena cava, emptying oxygen-poor blood from the body into the right atrium.
As the ventricle contracts, blood leaves the heart through the pulmonic valve, into the pulmonary artery and to the lungs where it is oxygenated
Capillaries. These small blood vessels connect the arteries and the veins.
Veins. These are blood vessels that take blood back to the heart.
Arteries. They carry oxygen-rich blood away from the heart to all of the body's tissues
Veins of the thorax. Superior vena cava. .
Heart. Cardiac fat
Arteries of the thorax. Descending thoracic aorta. ..
Pulmonary circulation. Pulmonary arteries.
continuation of the descending aorta and becomes the abdominal aorta when it passes through the diaphragm. ... These vessels supply blood to the head, neck, thorax and upper limbs.
great venous trunks that return deoxygenated blood from the systemic circulation to the right atrium of the heart
buffering coronary arteries against the torsion induced by the arterial pulse wave and cardiac contraction, facilitating coronary artery remodelling, regulating fatty acid homeostasis in the coronary microcirculation
carry deoxygenated blood to the lungs, where carbon dioxide is released and oxygen is picked up during respiration
