Breathing is the function of our body to let air flow to the lungs. It is important because it serves the purpose of bringing the amount of oxygen the body needs to work properly, and flushing out the toxic substances our body produces.
The diaphragm also plays its important role in respiratory system because it creates more space in our chest cavity, allowing the lungs to expand when we inhale.
The larynx connects the naso- and oro- pharynx with the trachea, functioning in air conduction, vocalisation and in obstructing passage of ingesta into the trachea during deglutition. The trachea divides into left and right mainstream bronchi. Bronchi give away to smaller conducting airways, bronchioles.
The walls of the alveoli share a membrane with the capillaries, this relatively lets the oxygen and carbon dioxide diffuse between the respiratory system and bloodstream. They bring oxygen into our body through inhalation and send carbon dioxide out called exhalation and overall process is respiration
Pneumonia is a life threatening illness because if our lungs is filled with fluid then they won’t be able to function normally and won’t be able to transfer enough oxygen to your blood or get rid of the carbon dioxide in our bloodstream

B. Only genetic engineering can produce an organism with desired
traits.
It can have all of the measures except 89 because an Acute angle is 45 degrees and less.
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.
