Which one of the following statements is true? A. Voluntary hyperventilation results in acidosis. B. Emphysema directly impairs
AlekseyPX

Answer:

The correct answer is option E.

Explanation:

Voluntary hyperventilation results in alkalosis, not in acidosis. Alkalosis takes place when the body possesses too many bases. It can take place due to decreased levels of carbon dioxide or due to enhanced level of bicarbonates in the blood, that is, a base.  

Emphysema directly impairs exhalation more than it directly impairs inhalation. Emphysema refers to a lung disorder, which leads to shortness of breath. In the individuals suffering from the condition, the air sacs in the lungs, that is, alveoli get damaged.  

The hemoglobin-oxygen dissociation curve shifts to the right at the time of metabolic acidosis. The low partial pressure of oxygen within the lungs results in the constriction of pulmonary arterioles. Thus, all the mentioned statements are false.

The proper function of the cardiovascular system relies on blood following the correct pathway through the heart. Valves within
Nadya [2.5K]

Answer:

The Mitral/Bicuspid Valve

Explanation:

The heart is composed of 4 chambers: left and right atria, and left and right ventricles. The “right heart” (right atrium and ventricle) receives deoxygenated blood from the systemic circulation through the Vena Cava, and impels this blood towards the lungs through the Pulmonary Arteries where it will be oxygenated. The “left heart” (left atrium and left ventricle) receives oxygenated blood from the pulmonary circulation through the Pulmonary veins and impels this blood towards the systemic circulation through the Aorta artery.

The systemic and pulmonary circuits work in series, and maintaining the unidirectional course of the blood flow is very important. This can be done by the presence of fibrous valves that are present between the atrium and the ventricles, and in between the ventricles and the Pulmonary/Aorta artery.

The location of these structures are as follows:

Systemic circulation ⇒ Right Atrium → [Tricuspid Valve] → Right Ventricle → [Pulmonary Valve] → Pulmonary Artery ⇒ Pulmonary circulation

Pulmonary circulation ⇒ Left Atrium → [Mitral/Bicuspid Valve] → Left Ventricle → [Aortic Valve] → Aorta ⇒ Systemic circulation
