Intestine

Large Intestine

The equine large intestine consists of the following segments (in aboral direction): the cecum, the large colon, and the small colon (Fig. 36-1). Although these segments form a continuum for the passage of digesta from the ileum to the anus, the three portions are considered to be separate structures, anatomically, functionally, and surgically. The large intestine of the horse is well developed...

The C. elegans intestine.

The intestine is one of the major organs in C. elegans and is largely responsible for food digestion and assimilation as well as the synthesis and storage of macromolecules. In addition, the intestine is emerging as a powerful experimental system in which to study such universal biological phenomena as vesicular trafficking, biochemical clocks, stress responses and aging. The present chapter de...

Common flora and intestine

Commensal microflora engages in a symbiotic relationship with their host, and plays an important role in the development of colorectal cancer (CRC). Pathogenic bacteria promote chronic intestinal inflammation and accelerate tumorigenesis. In sporadic CRC, loss of an effective epithelial barrier occurs at early stage of CRC development. As a result, non-pathogenic bacteria and/or their products ...

Liver and intestine transplantation.

The most significant development in liver transplantation in the USA over the past year was the full implementation of the MELD- and PELD-based allocation policy in March 2002, which shifted emphasis from waiting time within broad medical urgency status to prioritization by risk of waiting list death. The implementation of this system has led to a decrease in pretransplant mortality without inc...
