There is the digestive system is used to help you digest food.
The respiratory system that lets us use and brain oxygen.
Lastly, the circulatory system which allows our bodies to have flowing blood.
Answer:
Sternocleidomastoid, pectoralis minor, scalenes
Explanation:
During normal inhalation, contraction of the diaphragm and the contraction of external intercostals expands the chest cavity. The increased volume of the thoracic cavity results in reduced alveolar pressure than the atmospheric pressure to facilitate the flow of air into the lungs in response to the pressure gradient.
During deep inhalation as it occurs when running up the stairs, the accessory muscles of inhalation also participate to increase the volume of the chest cavity. The contraction of scalene and sternocleidomastoid muscles increase the volume of the chest cavity further to create a greater drop in alveolar pressure.
During forceful inhalation, the sternocleidomastoid muscles serve to elevate the sternum, the scalene muscles serve to elevate the first two ribs while the pectoralis minor elevate the third through fifth ribs.
Dependent on both the mineral assemblage of the protolith and the temperature and pressure of formation...
Or
both minteral content of the prolith and the temperature and pressure formation..
I really don't know my answer wrong or right....if it's wrong pls forgive me....
The chemical bond that occurs from the attraction of 2 oppositely charged atoms is an IONIC bond .
