Answer:

C. is a passive process caused by increased intrathoracic pressure.

Explanation:

Inhalation is an active process as it includes the contraction of muscles and diaphragm. Exhalation is a passive stage of breathing. It does not include any muscular contraction. Rather, diaphragm and the external intercostal muscles become relaxed. This reduces the volume of the thoracic cavity and lungs. The reduced volume causes increased air pressure in alveoli as compared to the atmospheric pressure. The increased pulmonary pressure drives the movement of air towards the outside of the body.

La sangre sale del ventrículo derecho por las arterias pulmonares y se dirige a los pulmones.
AveGali [126]

Answer:

Si, esto es lo que se conoce como circulacion menor.

Explanation:

La sangre cumple un recorrido en el corazon a la cual se la llama circulacion mayor, una vez que se continua su camino hacia los pulmones ahi ya pasa a ser circulacion sanguinea menor.

Estas circulaciones estan sumamente coordinadas y tienen un orden ritmico, con un unico fin, que es oxigenar la sangre que se recolecta de todo el organismo.

Es asi como la sangre que viene con CO2 entra a los pulmones posterior a la eyeccion cardiaca y cumple con el proceso de homeostasis en el alveolo y se oxigena.
