SAMA HOOLE: A gallbladder is a bile tank. It sits under the liver, concentrates bile until it is many times stronger than it arrived, and fires the whole lot in one pulse the second fat hits the small intestine.

- Camel
- Rat
- Pigeon

Animals with one:

- Dog
- Cat…

The horse has no gallbladder. Neither does the deer, the giraffe, the rhino, the elephant, the camel or the rat. Animals with no gallbladder: - Horse - Deer, every species bar the musk deer - Giraffe - Rhinoceros - Elephant - Camel - Rat - Pigeon Animals with one: - Dog - Cat - Lion - Human A gallbladder is a bile tank. It sits under the liver, concentrates bile until it is many times stronger than it arrived, and fires the whole lot in one pulse the second fat hits the small intestine. It is equipment for an animal that eats a large fatty meal and then eats nothing for a while. The dedicated grazers dropped the organ entirely, because a steady trickle of grass never asked for it. Bile just seeps out of the liver all day and that covers it. You kept yours. It has been sitting under your liver for two million years, loaded, waiting for something to arrive that justifies it.

Then a man in a leaflet told you to grill the chicken dry.
