Bronchitis

Bronchitis is an inflammation of the lower airways. It happens when the bronchi, located between the lungs, become inflamed due to an infection or some other cause. According to its duration and etiology, a distinction is made between acute bronchitis, short duration, and chronic bronchitis, long duration and frequent relapses.
Symptom
:
Cough with mucus, sometimes bloody. If the mucus of bronchitis is yellowish green and is accompanied by fever, it is most likely that there is bacterial infection.
Inflammation of the bronchi (ramifications of the airways between the trachea and the lungs).
Inflammation (edema) of the bronchial walls.
Obstruction of the alveoli.

Answer:
B. Right AV valve
Explanation:
In Human anatomy, cardiac cycle can be defined as a complete heartbeat of the human heart which comprises of sequential alternating contraction and relaxation of the atria and ventricles, therefore causing blood to flow unidirectionally (one direction) throughout the human body.
Generally, the cardiac cycle occurs in two (2) stages;
Diastole : in this stage, the ventricles is relaxed and would be filled with blood.
Systole: at this stage, the muscles contracts and thus, allow blood to be pushed through the atria.
Generally, the right atrioventricular valve (AV) is also referred to as the tricuspid valve and is located on the right dorsal side of the human heart. The right atrioventricular valve (AV) comprises of three (3) leaflets (flaps) which opens and closes in order to allow for the flow of blood from the right atrium of the human heart to the right ventricle. Also, the right atrioventricular valve is saddled with the responsibility of preventing blood from flowing backward in the mammalian heart.
Hence, the valve which is between the Right Atrium and ventricle is the right atrioventricular valve (AV).
