The correct answer is E. Vertebrates have a closed circulatory system.
Explanation:
The main mission of the circulatory system is to deliver oxygen and nutrients to all body cells.
In the closed circulatory system, blood travels inside a network of blood vessels, without leaving them. The material transported by the blood reaches the tissues through diffusion. It is characteristic of all vertebrates, including humans.
Gerd can cause damage to the throat and airways from gastric contents and can cause asmatic symptoms. It is also worth noting that gerd symptoms tend to worsen at night from laying flat.
