This article focuses on the occurrence of decompression sickness in diving, air-breathing marine vertebrates and hypotheses for how this can be limited. Most deep diving vertebrates contain more available space for oxygen, and smaller-sized lungs. The popularly studied prediction scientists made was that the collapse of the alveolar led to a reduction in nitrogen intake. As seen in Figure 1, rapid decompression leads to an increase in nitrogen tension pressure and ultimately causes decompression sickness. The researchers reference a study involving loggerhead sea turtles and the onset of gas embolisms. These turtles have the ability to manage gases by utilizing the pulmonary artery. From this study, they propose a new hypothesis to limit nitrogen saturation—adaptations in vertebrates can lead to a pulmonary functional shunt that can control alveolar collapse and cardiac output.

Suggestion
I think you are missing some context with this paragraph. You reference "this article" which the reader is unable to see or reference. You also call attention to "Figure 1" which when this paragraph is standalone (i.e. no article to pair it with) it is almost useless information.
You mentioned "hypotheses",
You mentioned "hypotheses", but only proposed one hypothesis.
Comment
"The popularly studied prediction scientists made was that the collapse of the alveolar led to a reduction in nitrogen intake." It is better to use active voice. Present the data, then the credit.
