Heart Anatomy
This is the medial cavity of the thorax where the heart is located
What is the mediastinum
This valve is located between the right atrium and right ventricle
What is the tricuspid valve
this is the period when the heart relaxes and the ventricles fill with blood
what is diastole
These vessels carry blood away from the heart
what are arteries
what is blood pressure
This is the pointed inferior portion of the heart that points towards the left hip
What is the apex
This valve is located between the left ventricle and the aorta
What is the aortic semilunar valve
this volume of blood pumped by each ventricle in one minute
what is cardiac output
these small vessels are responsible for controlling how much blood enters a capillary bed
what are arterioles
a blood pressure reading is reported in these units
what are mmHg (millimeters or mercury
This layer of the heart wall is made of cardiac muscle and is responsible for contraction
What is the Myocardium
Blood leaving the right ventricle travels through this vessel towards the lungs
What is the pulmonary trunk
this is the amount of blood pumped by a ventricle with each heartbeat
what is stroke volume
these vessels are called capacitance vessels because they can contain up to approx. 65% of the body's blood supply
what are veins
If a patient's blood pressure is 120/80, the difference between these two numbers is called what, and what is the answer to the mathematical problem
what is pulse pressure/ 40 mmHg
This dense connective tissue structure consists of four rings surrounding the heart valves and physically and electrically separates the atria from the ventricles
What is the fibrous skeleton
Put these structures in the correct order
pulmonary veins
left ventricle
left atrium
aorta
pulmonary veins, left atrium, left ventricle, aorta
If timmy's HR is 75 beats/min and his stroke volume is 70mL/beat, what is his cardiac output
5.25 L/min
these are the three major types of arteries discussed in lecture
this equation shows that mean arterial pressure is influenced by cardiac output and total peripheral resistence
What is MAP = CO X TPR
These irregular muscular ridges are found on the walls of the ventricles
What are the trabeculae carne
These structures anchor the cusps of the AV valves to the papillary muscles and help prevent the valves from inverting
what are the chordae tendineae
According to the frank-starling relationship, an increase in ventricular filling/stretch generally causes what change in stroke volume
what is an increase in stroke volume
this type of artery is located near the heart, contains a large amount of elastin, and acts as a pressure reservoir by expanding and recoiling
What is an elastic artery
At the arteriolar end of the capillary, what is the net filtration pressure, does the fluid flow in or out of the blood
+10mmHg, out
