Bees are able to expel both urine and feces, but they do not do so in the same way that humans do. Instead of using a separate exit for each, bees have a single opening called the Siphon which they use for both functions.
The bee first urinates into its rectum, where the urine is stored until it is ready to be expelled. When the bee is ready to defecate, it contracts its rectum muscles to push the feces out through the Siphon.
How does a bee’s digestive system work?
The bee’s digestive system is a long, coiled tube that starts at the mouth and ends at the anus. Along the way, there are several different organs that help to break down the food the bee eats and absorb the nutrients.
The first part of the bee’s digestive system is the esophagus. This is a short tube that connects the mouth to the stomach. The esophagus is lined with hair-like projections called setae. These help to move the food down the esophagus and into the stomach.
The stomach is a large, sac-like organ that is where the majority of digestion takes place. The stomach walls are lined with gastric glands that secrete enzymes that break down the food. The food is then moved into the intestine.
The intestine is a long, coiled tube. The walls of the intestine are lined with cells that absorb nutrients from the food. The intestine also has a number of bacteria that help with the digestion process. The intestine leads to the rectum, which is where the bee stores its wastes before they are eliminated.
