Lesson 2B (Part 3) Flashcards
What 2 veins join and make the IVC?
Right and left common iliac veins
What does the IVC receive as is ascends through the abdomen along the vertebral column?
Tributaries
Where is the IVC located? (3)
- Posterior to the liver
- Lateral to the aorta (right)
- Passes through the diaphragm
- T8
- drains in the lower part of the right atrium
What kind of structure is the IVC?
Retroperitoneal
What is the IVC anterior to? (3)
- Right psoas muscle
- Right renal artery
- Right suprarenal gland
What is the IVC posterior to? (3)
- SMA
- Pancreatic head
- Horizontal part of the duodenum
What dumps into the left renal artery? (2)
- Left suprarenal vein
2. Left gonadal vein
Why is the left renal vein larger than the right renal vein?
Because it is receiving more blood
Why is the left renal vein longer than the right renal vein?
The heart is on the left so it has to go around the heart
What 2 veins join to form the common iliac vein?
- External iliac vein
2. Internal iliac vien
What is the common iliac vein anterior to?
Sacroiliac joint
What do the common iliac veins drain?
The regions supplied by the arteries of the same name
Where do the common iliac veins pass?
Obliquely upwards from the SI joint to L5 where they join and form the IVC
Lumbar veins
4-5 pairs of vessels that collect blood from the muscles and skin of the posterior abdominal wall
Where do the gonadal veins ascend from?
The dorsal teste through spermatic cord into the abdomen
Where do ovarian veins originate?
In the ovary
Where do gonadal veins ascend?
Retroperitoneally in the abdomen
Where does the right gonadal vein go?
It opens directly into the IVC
Where does the left gonadal vein go?
Drains into the left renal vein
Where are renal veins located?
L2 and are anterior to the renal arteries
What does the left renal vein drain?
The left kidney
What does the left renal vein receive?
Left suprarenal vein and left gonadal vein before emptying into the IVC
Where is the left renal vein in reference to the aorta and SMA? (2)
- Anterior to the aorta
2. Posterior to the SMA
Where does the right renal vein drain?
The right kidney
Where is the right renal vein located?
Slightly inferior to the left renal vein
- because the right kidney is lower than the left
Which renal vein is shorter and more narrow?
Right renal vein
Why is the right renal vein shorter and more narrow than the left renal vein?
It has a shorter distance to go to the heart
Where do the suprarenal veins empty into? (R and L)
R = empties directly into the posterior aspect of the IVC L = empties into the left renal veins
Which side of the suprarenal vein is shorter?
Right
