Why is nose breathing preferable to mouth breathing

Biology

evablogger [386]3 years ago

Nasal breathing is preferred over mouth breathing because most of the oxygen is absorbed from the air while exhaling. The outlet of nose is smaller than the mouth due to which nose creates more air pressure which leads to slower exhalation and greater time for oxygen to get absorbed.

Nose is connected to lungs and heart through nerves and not breathing through nose will lead to disturbed heart rate and blood pressure.

Because the nose is well adapted to breathing than the mouth. The nose warms the air before it reached the lungs. It also filters out the dust and foreign particles using the nose hairs and mucus. The mucus also has antibacterial properties hence mitigating bacterial infections.

Examination of your slide will show that a few nuclei do not appear next to a cell wall
Svetradugi [14.3K]

Hello. This question is incomplete. The full question is:

"Examination of slide will show that a few nuclei do not appear next to a cell wall in onion cell. Could you explain that observation? "

Answer:

You are visualizing the onion cell during mitosis interphase. At that time, cells may have multiple nuclei and some of them may not be visible near the cell wall.

Explanation:

Experiments with onion roots are common when we want to visualize the phases of the cell cycle or to visualize chromosomes and cell nuclei.

If after the experiment with an onion cell you are unable to visualize the cell nuclei near the cell wall, it means that you are visualizing the cells during the interphase of mitosis. At that time, cells may have multiple nuclei and some of them may not be seen near the cell wall.
