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.

This is because the basketball is the bigger object here so that should represent something bigger like the solar system. Then the tennis ball would represent earth because it is the smaller object here.
The cerebrum (brain) can be divided into two hemispheres: the left hemispheres and the right hemisphere. These hemispheres are separated by a deep longitudinal fissure (i.e., the cerebral fissure).
- In this case, the patient will be able to identify the cat using his RIGHT-HAND.
- The left brain hemisphere receives sensory information from and controls movements on the right part of the body, and vice-versa.
- In consequence, the left brain hemisphere controls the movements of the right hand, whereas the right brain hemisphere controls the left hand.
