A Giraffe's heart, which can weigh up to 24 lb (10 kg), has to generate around double the normal blood pressure for a large mammal in order to maintain blood flow to the brain against gravity.
Background. Bacterial overgrowth syndrome (BOS) is a term that describes clinical manifestations that occur when the normally low number of bacteria that inhabit the stomach, duodenum, jejunum, and proximal ileum significantly increases or becomes overtaken by other pathogens.
Synonyms: stasis syndrome, stagnant loop syndrome, small intestinal bacterial overgrowth (SIBO) syndrome. In blind loop syndrome a portion of the small intestine becomes bypassed and thus cut off from the normal flow of food. This may lead to malabsorption and small intestinal bacterial overgrowth (SIBO) syndrome. It may also be associated with short bowel syndrome.
