Chap 1 Anatomy& Physiology Flashcards
What area of the heart lies most directly behind the sternum?
Right ventricle
What does the adult heart typically weigh?
Between 250 & 350g
What is the hearts innermost layer?
Endocardium
What is the location of the tricuspid valve?
Separates right atrium and right ventricle
What cond is chest discomfort or other related symptoms of sudden onset that may occur because the increased oxygen demand of the heart temporarily exceeds the blood supply?
Angina pectoris
What receptor sites are found in the arterioles of the heart, lungs, and skeletal muscles?
Beta 2
This refers to the speed of conduction through the AV junction.
Dromotropic effect
In a resting adult, each cardiac cycle lasts approximately:
0.8
During this, blood from the superior and inferior vena cava and the coronary sinus enters the right atrium
Atrial diastole
This is the force exerted by the circulating blood volume on the walls of the ateries
Blood pressure
