Over time, the toxins from inhaled cigarette smoke break the thin walls of alveoli, leaving larger, less efficient air sacs. The sacs also begin to lose their bounce, making it harder to bring in the oxygen and expel carbon dioxide. 3 Both can become partially trapped in the lungs.

Mashcka [7]

The swim bladder is more or less an oval, soft-walled pouch located in the abdominal cavity, just below the spinal column. Its shape varies greatly, but the volume is constant between species, most often around 5% of body.

<h3>Day of deep-sea fishing</h3>

1. The volume of your swim bladder when you put it back in the water would be 7.5 liters.

2. The time the fish would float on the surface before the oval could restore neutral buoyancy would be a few seconds.

3. If I were a red blood cell that has just delivered its oxygen to the tail musculature of a mako shark, the route through the circulatory system to eventually reach the mako's swim bladder would be the venous route, like other fish, they have a heart with two chambers, an atrium and a ventricle, and closed circulation.

With this information, we can conclude that the volume of her swim bladder when she was put back in the water would be 7.5 liters.
