The Pouch

The pouch: what a very useful structure!

By definition a “pouch” is a small sac-like container to store or keep things in. Biologically speaking, it is a pocket-like space in or on the body and the ‘pouches’ in our cheeks, for example, come to mind. They are useful for sucking up liquids (without these pouches as in the case of many carnivores like dogs and cats, liquids would have to be leapt up). —>—>

Experiments that shouldn’t be done, can’t be done or can but won’t be done

I remember a part of that hilariously silly Monty Python series, in which someone wanted to jump across the Channel and dig a tunnel from England to Australia. And of course my children asked me if that was really possible. Well, they were children, but even now I sometimes get unusual questions, but they’re from adults. One of the more common ones is whether humans can mate with chimps and produce offspring. The interest in that probably stems from the suggestion by someone that the original source of the HIV-infection (i.e., AIDS) in humans were chimps. Let’s examine then.

Dysentery, loose stool, running belly

It’s all unpleasant and called diarrhoea

Stomatologists are experts focusing on the structure and function and the surrounding area of that part of the body through which the food enters. Proctologists are interested in the structure and function of the part of the body from where the waste comes out. And psychologists are interested to study why (mostly) very young children in particular are so interested in their own faeces and find it so amusing to examine what they can produce from their rear ends. When, however, what comes out of there is a semi-liquid, brownish and soft and sticky, smelly slush, it’s certainly much less amusing.
