Answer:
b. insertion of a cannula into the external iliac vein
Explanation:
A saphenous cutdown refers to a skin incision associated with insertion of a cannula into the external iliac vein.
It is a more invasive method of exposing the saphenous vein. A cut is made into the skin which is not very deep. A part of vein is exposed which is then cut out for the insertion of cannula. It does not stop the flow of blood, instead it just changes the course. It is also known as the circulatory blood flow.
Answer: A. Ascending and transverse colons
Explanation:
The ascending and transverse colons will be impaired due to injury because Blood from the superior mesenteric artery and parasympathic nerve fibres from the vagus nerve is collected by the ascending and transverse colon.
However, blood from the lower mesenteric artery and parasympathic nerve fibres from the pelvic splanchnic nerve originating from sacral spinal nerves (S2-S4) is provided by the descending and sigmoid colons.
Hence, the correct answer is A. "Ascending and transverse colons".
