What Is a Gastrovascular Cavity?
The gastrovascular cavity is a structure found in primitive animal phyla. It is responsible for both the digestion of food and the transport of nutrients throughout the body. The cavity has only one opening to the environment. Food goes in and waste comes out that same opening, making it a two-way digestive tract.
By contrast, organisms that have a mouth on one end with an anus on the other end have a one-way digestive tract, called an alimentary canal. Food goes in the mouth, while waste comes out the anus.

Explanation:
The carbohydrate-insulin hypothesis states that when we consume processed meals, which raise insulin levels, calories are subsequently stored in fat cells.
Carbohydrate-insulin hypothesis:
- According to the carbohydrate-insulin hypothesis, weight gain occurs when a person consumes an excessive quantity of processed carbs, which raises insulin levels and leads the body to store fat.
- Although fat is necessary for your body to operate, having more fat than you need might have negative effects on your health. It has long been believed that consuming more than the body needs for energy results in obesity, which is characterized by an abnormal amount of body fat.
- The "calories in, calories out" idea of weight growth, according to some scientists, is an oversimplification and that obesity is likely the result of a much more complicated process.
- Consuming processed meals increases insulin secretion while decreasing glucagon secretion. As a result, the body may store more fat, which can slow the metabolism and make people feel more hungry.
