Por que o nosso nariz fica entupido quando estamos resfriados?

why does our nose get stuffy when we have a cold

Due to dilation of blood vessels in the sinuses of the nose

Explanation:

Often times, we think our nose gets stuffed up due to the excess mucus in times of cold but it is not always so.

We get stuffed due to the body's homeostasis, a drive to internally control and balance the outside environment.

During cold, blood vessels dilate so as to allow for more inflow of blood. Incoming blood brings in more heat to the body parts.

The return of the wolf to yellowstone national park will probably affect the bird population to some degree, not significantly. while wolves will hunt birds when necessary, they prefer to hunt larger prey. the bird population will most likely only be affected when hunting is scarce for the wolves. birds of prey will also probably not be affected as much as other birds who spend more time on the ground hunting for food as the tend to spend more time in the air or in trees since they do not need to stay on the ground for long due to the nature of the way they hunt.
