The stethoscope is a device commonly used by doctors to monitor heart function. When listening to a heart beating using a stetho
Effectus [21]

Answer:

The correct answers are:

1. closing

2. the ventricles and arteries,

3. a constricted trachea

Lub is the first sound of a heartbeat and is mentioned as S1. It is usually produced due to the closing of tricuspid and and mitral or bicuspid valves present between atria and ventricles.

Tricupsid is located between atrium and ventricle of the right hand side and mitral valve is located between atrium and ventricle of the left hand side. They prevent the back flow of blood from ventricles to their respective atria.

Dub, being the second sound is written as S2. It is produced due to the closing of pulmonary (located between right ventricle and pulmonary artery) and aortic valves (located between left artery and aorta).

These valves prevent the back flow of blood from arteries into the ventricles.

The time between the two sounds is often taken as the measure of the diastole i.e. ventricular filling.

Wheezing refers to a high-pitched sound produced when a person breathes, especially during exhale. It is caused by constriction of the airways or inflammation. It is considered as a symptom of various diseases such as asthma, COPD, allergies, bronchitis etc.

Mamont248 [21]

During prophase, which occurs after G2 interphase, the cell prepares to divide by tightly condensing its chromosomes and initiates mitotic spindle formation. The chromatin fibers condenses into discrete chromosomes. The nucleolus also disappears during early prophase.
