LAB 2 Flashcards
(24 cards)
What is shown in this image?
where does it drain?
How is it formed?
Azygos vein
runs up the right side of the thoracic vertebral column. drains the posterior walls of the thorax and abdomen to the SVC. Provides alternate path for blood to RA by letting blood flow b/w vena cava when one VC is blocked.
Formed by union of R ascending lumbar vein with R subcostal vein in 12th
What is the image showing?
inferior pulmonary veins
- bring oxygeneated blood from lungs to left atrium
What does this image show?
primary bronchi
-trachea divides to two main or primary bronchi
What does this image show?
L secondary bronchi
what does this image show?
carnia
“keel”
cartilaginous ridge that projects into the trachea and split between L and R primary bronchi
What is the coronary sulcus?
Oblique Groove that separates the Atria from the Ventricles. Contains coronary vessels and adipose tissue.
Coronary artery lies on the coronary sulcus of the RA and RV.
What is the anterior interventricular groove?
1/2 grooves that separates ventricles of heart.
On anterior side.
Left anterior descending branch of left coronary artery runs in the groove.
What is the posterior interventricular groove?
1/2 grooves that separates the ventricles of the heart.
On posterior side.
Contains posterior interventricular artery and middle cardiac vein.
What do ventricles do?
The pumping of the heart
large and thick walled
What do atria do?
receive and pump blood to ventricles
small and thin-walled
What is this image showing?
Where does it travel down and originate from?
What does it supply?
Right coronary artery (RCA)
originates above the ascending aorta, right cusp of valve. Travels down coronary (atrioventricular groove).
Supplies blood to RV.
Supplies 25-35% blood to LV.
What does this image show?
posterior interventricular artery (PIV)
or posterior descending artery (PDA)
or inferior interventricular artery
runs in posterior interventricular groove to apex of heart where it meets with anterior interventricular artery.
Supplies posterior 1/3 of interventricular septum.
What is shown in this image?
Left coronary artery
arises from ascending aorta above the left cusp of the valve. Supplies blood to left side of heart.
What is shown in this image?
anterior interventricular branch
(left anterior descending) or LAD
- courses in the anterior interventricular groove to apex
- can anastamose (allow multiple possible pathways of blood flow to same tissue)
with posterior interventricular branch of right coronary artery AT APEX.
What is shown in this image?
Circumflex branch
or Circumflex artery
- follows coronary sulcus around left border of the heart and gives off marginal arteries most notably the left marginal artery of circumflex
- can anastomose with RCA in the coronary sulcus
What does this image show?
Coronary sinus
- large dilated vein that travels in the coronary sulcus on posterior surface of heart.
- receives blood from all cardiac veins except anterior cardiac vein as it drains into RA
- Returns blood to RA
What does this image show?
Great cardiac vein
- originates on the anterior surface of heart near apex, ascends ( goes up stream) with left anterior interventricular coronary artery
What does this image show?
Middle Cardiac Vein
-originates on posterior surface of heart in the posterior interventricular groove
- ascends (goes up stream) with posterior interventricular coronary artery
What does this image show?
Small cardiac vein
- originates on anterior surface of heart along inferior margin of RV and ascends (goes up stream) with right marginal coronary artery.
What is shown in this image?
Apex
pointed “tip”
part of superior lobe
What is shown in this image?
Base
- broad, concave, and rests upon convex surface of diaphragm.
- due to diaphragm extending higher on R side, concavity on base of R lung is deeper.
What is shown in the image?
Oblique fissure
- divides upper and lower lobes and middle and lower lobes of R lung
What is shown in this image?
Horizontal fissure
- divides upper and middle lobes of R lung
