Heart
The area that is supplied blood by the coronary arteries.
What is the myocardium?
What is another name for the Mitral valve?
Bicuspid valve
Sites of gas exchange
Capillaries and alveoli (lungs)
These blood vessels prevent backflow (have valves) and carry blood to the heart.
Veins
These blood vessels are strong, elastic and carry high-pressure blood away from the heart.
What are Arteries?
This term indicates a heart rate greater than 100 bpm.
What is tachycardia?
Where deoxygenated blood enters the heart
right atrium
This term is used for a heart rate less than 60 bpm.
What is bradycardia?
Largest artery in the body (about the size of a garden hose).
Aorta
Name the four chambers of the heart. (Remember right and left)
Right and Left Atrium, Left and Right Ventricle
What chamber does the blood return to once it leaves the lungs.
Left Atrium
This is the longest vein in the body.
What is the great saphenous vein?
Heart chamber that supplies oxygenated blood to the aorta.
What is the Left Ventricle?
What type of blood is in the pulmonary artery(oxygenated or deoxygenated)
deoxygenated
This wave in the EKG indicates repolarization of the ventricles.
What is the T-wave?
The cardiovascular system consists of these structures
What is the heart, arteries, capillaries and veins.
Blood vessels that carry blood from the veins into the right atrium.
What is the vena cava?
This states that the greater the length of stretched cardiac fibers, the stronger the contraction.
Blood vessel carrying oxygenated blood to the left atrium
pulmonary vein
This wave indicates the depolarization of the atria in an EKG.
What is the p-wave?
What is the name of the valve between the right atria and right ventricle
Tricuspid
Hypercalcemia can lead to a(n) _____________ in heart action. Whereas, hypocalcemia can lead to a(n) ______________ in heart action.
What is increase and decrease?
The external jugular vein drains these 3 areas.
What are the face, scalp, superficial neck?
A diet high in saturated fats, high blood pressure, lack of exercise, obesity and smoking are all risk factors of hardening of the arteries, also known as this.
This reading is considered hypertensive.
What is greater than 120/80?
These are the four valves inside the heart.
What is the Tricuspid, Mitral or bicuspid, Pulmonary, and Aortic
This is the function of the pulmonary circuit?
What is blood between the heart and lungs. The right side of the heart pumps deoxygenated, or oxygen-poor, blood to the lungs. In the lungs, carbon dioxide is exchanged for oxygen. Then the oxygenated, or oxygen-rich, blood returns to the left side of the heart?
This part of the EKG indicates depolarization of the ventricles and repolarization of the atria.
What is the QRS complex?
This is the function of the systemic circuit.
What is sends oxygenated blood to all body cells where it drops off oxygen and picks up carbon dioxide where it is returned to the heart then lungs, then expelled from the body?
This may happen in hyperkalemia which can be life-threatening.
What is decreased heart rate and force of contraction?
