Deoxygenated blood from the large intestine flows mostly into the superior and inferior mesenteric veins. Small intestine cancer: Rarely, cancer may affect the small intestine. A medication newly approved for ulcerative colitis, ozanimod (Zeposia®), acts as a sphingosine-1-phosphate (S1P) receptor agonist, sequestering lymphocytes to peripheral lymphoid organs and away from their sites of chronic inflammation.
