Buy a new football. Sorry.
the inside of a football
My mother was recently told that she has air in her bladder. Her doctor said that there are two ways that air can get into the bladder. One is when a catheter is inserted air can go in with it. The other is a fistula between the colon and bladder that allows air to enter from the colon into the bladder. I have since seen an article that says that bladder infections can sometimes cause gas (air) to build up in the bladder. Hope this helps!
air bladder is present which regulates buoyancy
By football I am assuming American football. It is a rubber bladder with leather sewn around it and then inflated.
To use as a football
The bladder is typically an empty organ until it fills with urine. It does not normally contain air, but if air is present, it could indicate a medical issue such as a bladder fistula or emphysematous cystitis. If you suspect you have air in your bladder, it is important to consult a healthcare provider for further evaluation.
no, they have a swim bladder but this is so the fish can stay afloat
using a pigs bladder
The 'invention' of football goes back as far as the 11th century in England. During those days the football was an inflated bladder, usually from a pig. This is where the term 'pigskin' came from. In 1876, colleges that played football agreed upon a ball to be used that consisted of a vulcanized rubber bladder encased within leather. So, to answer your question, the first football was made from a pig's bladder.
It is a bladder of air.
There has to be a slit somewhere to insert the air bladder through, THat slit is then closed with the laces.
