Which muscles assist in inhalation when running up the stairs? A) sternocleidomastoid, pectoralis major, scalenes B) sternocleid
Ulleksa [173]

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.

When the hare population increases, what happens to the lynx population? Why?
Kamila [148]
 <span>The lynx population will increase. Then the hare population will drop because they're being eaten by all the lynxes and so the lynx population will drop too because they won't have much food. These things can be modeled with differential equations.</span>

The circulatory system consists of two divisions and is supplied with blood by different sides of the heart. The right heart sup
liq [111]

Answer:

pulmonary circuit,  systemic circuit

Explanation:

The circulatory system consists of 2 circuits -

pulmonary circuit

systemic circuit.                  

The pulmonary circuit carries deoxygenated blood. The right auricle receives the impure blood by superior and inferior vena cava, then the blood enters the right ventricle. From the right ventricle, the deoxygenated blood moves to the lungs by the pulmonary artery.

In the lungs, the deoxygenated blood gets oxygenated and enters the left ventricle through pulmonary veins. The pureblood then passes into the left ventricle and then the ventricle pumps the oxygenated blood to different parts of the body. This blood passes to the body aways from the heart by aorta. When the blood gets deoxygenated, it again enters the right auricle. In this way, double circulation occurs and both types of blood do not mix together.
