Question | Answer |
Where is the Inferior Vena Cava located? | Vein entering LOWER Right Atrium |
What is the function of the Inferior Vena Cava? | Receives blood from Lower Extremities and Abdomen |
Where is the Superior Vena Cava located? | Vein entering UPPER Right Atrium |
What is the function of the Superior Vena Cava? | Receives blood from Head and Upper Extremities |
What are considered "Upper Extremities"? | everything Above the Heart |
Where is the Pulmonary Artery located? | from Right Ventricle ---> Lungs |
Where is the Ductus Arteriosus located? | in the Pulmonary Artery |
What is the function of the Ductus Arteriosus? | connect R & L Ventricles --> blood will bypass lungs in utero |
What is the Ductus Arteriosus called after birth? | Ligamentum Arteriosus |
How many Pulmonary veins are there? | 4 - from Lungs --> Left Atrium |
What structures are used for blood to bypass the lungs in fetuses? | Foramen Ovale, Ligamentum Arteriosus |
Where is the Aorta located? | leaves the Left Ventricle |
What are Coronary Vessels? | R & L Arteries are the 1st branches of Aorta --> Myocardium |
Where do Cardiac Veins go? | to the Coronary Sinus |
What is the function of Cardiac Veins? | Return blood FROM Myocardium --> Right Atrium |
Where does the Aortic Arch lead? | Thoracic Aorta |
What are the 3 major branches of the Aortic Arch? | 1. Brachiocephalic; 2. LEFT Common Carotid; 3. LEFT Subclavian |
How many veins return blood to the Right Atrium? | 3 - Inferior/Superior Vena Cava, Coronary Sinus |
How does blood flow from Right Atrium --> Coronary Sinus? | R Atrium --> R Vent. --> Pulm Art. --> Lungs --> Pulm Veins --> L Atrium --> L Vent. --> Aorta --> Coronary Arteries --> Myocardium --> Card. Veins --> Coronary Sinus --> R Atrium |
What is the function of Heart Valves? | to prevent flow back "Regurgitation" |
What does AV stand for (with respect to valves)? | Atrioventricular |
What are the flaps of valves restrained by? | Chordae Tendinae connected Papillary Muscles |
What are the types of heart valves? | Atrioventricular, Semilunar |
What is similar about AV and Semilunar Valves? | Identical in Anatomy, different in function |
Give examples of AV Valves? | R= Tricuspid, L= Mitral |
Give examples of Semilunar Valves? | R= Pulmonary, L= Aortic |
Where is the Mitral Valve located? | between the LEFT Ventricle and LEFT Atrium |
Where is the Tricuspid Valve located? | between the RIGHT Ventricle and RIGHT Atrium |
