Heart Strucutre And Function Flashcards
Aorta
Carries blood away from the heart to the rest of the body
Vena Cava
Puts blood back into the heart from the rest of the body
Pulmonary Artery
Carries deoxygenated blood from the lungs to the heart
Pulmonary Veins
Takes oxygenated blood from the heart to the lungs
Coronary Artery
This provides blood and glucose to the heart so that the heart can do it’s job for pumping blood around the body. After the heart takes in the blood, it will pump it through to the lungs so that it can be pumped around the body
Coronary Heart Disease
It’s when fats get into the walls of the coronary veins, meaning less oxygen can get to the muscle cells so the heart can pump blood around the body. This can lead to a heart attack
Stent
It’s a metal wire put through the artery in your leg to put al the way into your heart. After you expand the stent, it’ll hold the artery open, making sure that blood flow is efficient. A stent can cause blood clots to happen where they’re used, which may increases the chance of a heart attack
Statins
Statins are used to lower the level of cholesterol on the blood and protect he insides of artery walls. High levels of cholesterol can lead to fatty deposits building up in your arteries. This increases the chance of a heart attack. There are minimal disadvantages of taking a statin, mainly just annoyance
Leaky Valves
Heart valves have to withstand a lot of pressure, and over time may become stiff and not open fully, causing the heart to become less efficient. This is extremely bad because it can cause a back draft of blood, which can cause damage to the heart. It can also cause blood to spill from the left atrium to the right atrium
Leaky valves can be replaced by mechanic valves, or other animal valves. If you get a mechanical valve, it’ll last a lifetime but you’ll need to take anti blood clotting drugs. If you get an other animal valve it won’t last forever, but you won’ have to take drugs to stop blood clotting
Artificial Pacemaker
It’s a device used to regulate the heart’s rhythm using electrical pulses. An internal pacemaker is an artificial pacemaker attached to the heart, where the electrodes to the heart, the electronic circuitry, and the power supply are all implanted within the body. An internal pacemaker sits just above the right atrium
Artificial Heart
It’s a device that’s meant to replace the heart. They’re usually used in the time between the removal of a heart and a heart transplant, but can be used to replace the heart if a heart is impossible to get for a heart transplant. It’s made to last for five years, but since it’s larger than a normal heart, some women and most children SHOULD NOT use an artificial heart as it could cause damage to their body
