Cardiovascular System - Wet Room St. 3 and 4 Flashcards
How is the heart wall supplied with blood?
- Left and right coronary arteries and their anastomosing branches
How is deoxygenated blood drained from the heart?
By the cardiac veins into the coronary sinus in the right ventricle
Identify the atrioventricular and intraventricular sulcus
- Atrioventricular sulcus
- Intraventricular sulcus
Identify the arteries
A. RCA and circumflex anastomose
B. Left main coronary artery
C. Right coronary artery
D. Circumflex
E. Posterior descending
F. Left anterior descending
Which part of the aorta do the coronary arteries arise?
- Ascending
- Coronary ostia
Which arteries anastomose in the coronary sulcus?
- Circumflex
- RCA
Which arteries anastomose in the intraventricular sulcus?
- Posterior descending
- Anterior descending
What structures does the RCA provide with blood?
- RA
- RV
- AV node
- SA node
What structures are supplied by the left coronary artery?
- Both ventricles
- LA
- SA node
Identify
- Great cardiac vein
- Oblique vein of left atrium
- Middle cardiac vein
- Small cardiac vein
- Coronary sinus
- Anterior cardiac veins
Where do lymphatics from the heart drain?
- Tracheobronchial lymph nodes
- Mediastinal lymph nodes
Where is the cardiac plexus and what nerves pass through it to innervate the heart?
- Located at the bifurcation of the trachea
- Vagus (parasympatheti)
- T1-T4 (sympathetic)
Where does the SA node lie?
- Near the opening for the SVC
Where does the AV node lie?
In the inferior part of the interatrial septum
Where is the bundle of his found?
Within each side of the interventricular septum
