So overall bees

So overall bees, humans and tuna have quite different gas exchange systems. They all increase their surface area to volume ratio differently. In humans the small folds and the shape of the alveoli increase the surface area, in tuna they have filaments and lamellae in their gills these are long and thin to make sure it can maximise the surface area. Then honey bees use their tracheoles which oxygen diffuses straight into and then the tracheoles go straight to every cell in their bodies.
Humans and tuna both have circulatory systems, so the oxygen is absorbed by the blood and taken to the gas exchange surface. It’s really good because humans and fish are not limited by their gas exchange system on how big they grow, whereas honey bees don’t have a circulatory system they use their tracheoles to transport their oxygen to every cell. So, this will limit how big they can get because the bigger the bee grows the harder it will be for the oxygen to get to every cell in the body by diffusion. The circulatory system means the gas exchange system that Tuna fish and humans have is a lot more efficient than of the honey bees.
So, tuna fish gets their oxygen from the water, but humans and honey bees take in oxygen from the air. The oxygen concentration in the water is a lot lower than it is in the air. This means it is a lot harder for fish to ventilate their oxygen because the water is more viscous than sir. Therefore, fish have a counter-current system which helps them to have a more effective way of getting enough oxygen from the water. As well as a more efficient way of getting oxygen into their blood stream.
Different to tuna fish, humans and bees use tidal ventilation. This is where air comes in and out of the body the same way. This is not the most efficient way of ventilating the gas exchange surface because not all the air that has just been breathed in makes it out of the body, so not all the air coming in still has oxygen in it. Humans and honey bees don’t get the most out of the oxygen in the air. Over all tuna fish have a way more efficient way to ventilate than bees and humans.
