Answer Choices:
Inferior mesenteric artery
🔺 The inferior mesenteric artery supplies blood to the distal segments of the large intestine and the rectum.
🔺 It branches from the abdominal aorta and provides oxygenated blood to the descending colon, sigmoid colon, and rectum.
🔺 This is essential for maintaining the metabolic needs of these portions of the digestive tract.
🔺 The inferior phrenic arteries supply the diaphragm, the gonadal arteries supply the reproductive organs, and the renal arteries supply the kidneys.
🔺 Thus, only the inferior mesenteric artery is responsible for perfusion of the lower digestive tract.
