Question

match the vessel with the tissue it drains.

match the vessel with the tissue it drains.

1. superior mesenteric vein
2. left gastric vein
3. cystic vein
4. phrenic vein
5. internal iliac vein
6. femoral vein
7. digital vein

options:
thigh
pelvis and its viscera
small intestine and most of the colon
diaphragm
gallbladder
toes
stomach

Explanation:

To match each blood vessel with the specific tissue or organ it drains, we analyze the anatomical pathway and drainage territory of each vein listed.

Analyze abdominal venous drainage

The superior mesenteric vein drains blood from the small intestine and most of the colon (specifically up to the splenic flexure). It then joins the splenic vein to form the hepatic portal vein.
The left gastric vein runs along the lesser curvature of the stomach, draining blood directly from the stomach before emptying into the hepatic portal vein.
The cystic vein drains blood from the gallbladder and typically empties into the right branch of the portal vein.

Analyze diaphragmatic and pelvic drainage

The phrenic veins (specifically the inferior phrenic veins) drain blood from the diaphragm.
The internal iliac vein drains blood from the pelvis and its viscera, including pelvic organs, gluteal region, and perineum.

Analyze lower limb drainage

The femoral vein is a deep vein of the lower limb that drains blood from the thigh.
The digital veins of the lower extremity drain blood from the toes.

Answer:

No.	Vessel	Tissue Drained
2	Left gastric vein	Stomach
3	Cystic vein	Gallbladder
4	Phrenic vein	Diaphragm
5	Internal iliac vein	Pelvis and its viscera
6	Femoral vein	Thigh
7	Digital vein	Toes
