Heart --> Vessels


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
