Question

Microbes that are generally enter the body through nose, are likely to affect
A. gut
B. lungs
C. liver
D. lymph nodes

Answer 1

Hint: The microbes are capable of causing disease usually by entering the human body through the eyes, mouth, nose, or urogenital openings, or via wounds or bites that breach the skin barrier.
This can spread or transmitted by several routes.

Complete answer:
As the nose leads to the lungs, so microbes that enter the body through the nose will affect the lungs.
The microorganisms that occupy the host organism through the nose will directly affect the respiratory system.
These will affect the lungs and the air tubules like bronchioles and the alveoli.
These will be responsible for the irritation in the respiratory passage.
Therefore, the correct answer is option is B.

Additional information:
The microorganisms that occupy the host organism through the nose then they directly affect the respiratory system.
These will affect the lungs and also the air tubules like bronchioles and the alveoli.
These will result in irritation in the respiratory passage.
These may produce secretion in the lungs or in the bronchioles; this condition is called bronchitis.
These may restrict the passage of the air in the respiratory system which is a condition that may cause chest infection or may result in asthma.
The microscopic creatures including bacteria, fungi and viruses are able to make you ill.
Most of them don't harm you at all.
Also they help to digest food, protect against infection and even maintain the reproductive health.

Note:
Things to remember that:
A pathogen is a microorganism that has the potential to cause disease.
An infection is the invasion and multiplication of pathogenic microbes in an individual or population.
Disease is when the infection causes damage to the individual’s vital functions or systems.
An infection does not always result in disease.
