Answer:
A. Mucus secretions that block airways
B. Inflamed airways that obstruct airflow
E. Overinflated alveoli that impair gas exchange
Explanation:
Chronic obstructive pulmonary disease (COPD) causes problems in air-flow and breathing. It is indicated by shortness of breath, cough, mucus production and wheezing. COPD is caused by genetic factors, long term exposure to irritating gas and most commonly by smoking.
The long term exposure to tobacco results in blocked air ways and destruction of airways. Emphysema and chronic bronchitis are two most common causes of chronic obstructive pulmonary disease.
Chronic bronchitis;
A) It is the inflammation of airways that obstruct airflow.

Answer:
The answer is: hidden testes
Explanation:
Testes - this is also known as <em>"testicles."</em> T<u>his refers to the oval-sized organs of the male reproductive system that is responsible for producing sperm.</u>
Hidden testes is also known as <em>"undescended testes." </em>Medically speaking, this is called<u> "Cryptorchidism." </u>This commonly affects <em>very young boys, especially those who were born prematurely</em>. This means that the testes couldn't fully descend on the 7th month of gestation (when it is supposed to).
Most of the time, only one testes cannot descend, but in some cases, both testes cannot descend, although it only accounts 10% of those with this disorder. Having undescended testes means that the male's sperm production is disrupted. <u>The production of sperm requires a certain temperature that is lower than that of the body temperature.</u> It's location should be outside and not inside.
