Cardiovascular Drugs: Cardiovascular Physiology Flashcards
(23 cards)
A sympathetic stimulation towards the heart rate.
Positive Chronotrope
A parasympathetic stimulation towards the heart rate.
Negative Chronotrope
- “end-diastolic volume”
- amount of blood volume entering the ventricles
Preload
- “systole”
- Where ventricles contract
Afterload
-How hard the myocardium contracts for a given preload.
Contractility
What influences contractility?
Ionotropes
What influences contractility?
Inotropes
Blood vessels containing blood flowing to the heart
Veins
Blood vessels containing blood flowing from the heart
Arteries
Receives blood from the head, neck, upper limbs, and chest
Superior vena cava
Receives blood from the trunk, viscera, and lower limbs
Inferior vena cava
The first entry from Superior and Inferior vena cava
Right atrium
Blood flows from the right atrium through this passage with “3 flaps” before reaching the right ventricles.
Tricuspid valve
After the tricuspid valve, the blood goes to the___
Right ventricle
Where does the oxygenated blood leave?
Pulmonary Artery
After passing through the pulmonary artery, where does the deoxygenated blood go?
Lungs. To discard CO2 and picks up O2 once again.
After the blood becomes oxygenated by the lungs, where does it go?
Pulmonary vein
What comes after the pulmonary VEIN?
Left atrium
Blood flows from the left atrium through this passage with “2 flaps” before reaching the right ventricles.
Bicuspid valve/Mitral valve
After the Bicuspid valve?
Left ventricle
Before reaching the aortic arch it must go through?
Aortic semilunar valve
The “big aorta” in which blood goes through right after passing through the aortic semilunar valve
Aortic arch
After the aortic arch? what now?
It is now distributed to the whole systemic circulation. duh! charot
