Bronchoconstriction is parasympathetic.... It has a decreased radius and increased resistance. At rest the bronchioles can be constricted, dont need a large diaameter..
therefore airflow is decreased making breathing harder..
Irritation of the airway can stimulate coughing reflexes, leading to increased respiratory rate and effort to clear the irritant. It can also trigger bronchoconstriction, which narrows the airways and can make breathing more difficult. Inflammation from irritation can also affect the efficiency of gas exchange in the lungs.

Loosen tight collars to make breathing easier.
In general humans are making survival more difficult for elephants. However, some humans are tyring to make it easier.
An upright position that makes breathing easier is called the high Fowler's position. In this position, the person's upper body is elevated to at least 45-60 degrees, which can help improve lung expansion and make it easier to breathe. It is commonly used in hospitals for patients experiencing difficulty breathing.

Thare less difficult to make and easier to carry around.
Because if you wanted to make things easier, you should have made those changes, not these!
False. Friction is a force that resists motion, so it can make work more difficult rather than easier. Minimizing friction can help make work easier.
