Final answer:
The gallbladder and urinary bladder can cause dangerous situations in trauma due to the potential release of fluids that lead to infection. Gallstones can block the bile duct, leading to jaundice and necessitating surgery. The gallbladder's removal affects bile concentration but not production, preserving most digestive function.
Step-by-step explanation:
The gallbladder and the urinary bladder are considered dangerous in trauma because they contain fluids (bile and urine, respectively) that, if released into the abdomen due to injury, can cause inflammation and infection. In the case of the gallbladder, a common issue is the formation of gallstones, which are solid particles created as a byproduct of cholesterol accumulation within the gallbladder. These gallstones can block the bile duct, potentially leading to serious complications like an infected, inflamed, or perforated gallbladder. Such a condition may necessitate surgical removal of the gallbladder. Although the gallbladder's role in concentrating bile is removed post-surgery, bile production by the liver continues, causing little serious effect on digestion.
Furthermore, if the bile duct is blocked, the backup of the bile pigment bilirubin may lead to jaundice, evidenced by a yellowing of the skin and eyes. This condition can further complicate the trauma, requiring immediate medical attention and often surgery to resolve.
