Where does the trachea extend to?

The trachea extends from the larynx down into the lungs. Its major function is that it connects the larynx and pharynx to the lungs and allows humans to breathe.

What is the difference between the vagus nerve and the parasympathetic nerve relating to the respiratory system?

Vagus nerve has a lot of branches. Some of them form a motor supply to the muscle (thru recurrent laryngeal nerve) whereas some form a parasympathetic chain that supply the respiratory system and other system too (ie: Cardiovascular parasympathetic also supplied by the brach of vagus)

The branches of the vagus that differ the motor function and the parasympathetic fuction related to the respiratory system.

How do symbiotic interactions impact digestion?

There are symbiotic relationships between animals and bacteria in the digestive area. The animals give the bacteria a place to live and the bacteria help break down food. Digestion would be a lot more difficult without these symbiotic relationships.

14 month old upper respiratory infection heal on its own?

If it has been present for 14 months, it probably will not heal on its own. You better call a doctor for some advice.

What is the mortality rate due to respiratory failure associated with myasthenia gravis?

In a few cases, the severe weakness of MG may cause respiratory failure, which requires immediate emergency medical care. Advances in medical care have reduced the mortality rate to about 3%.

What foods do you eat to keep the respiratory system clean?

No specific food does that. Eat a healthy, balanced diet, and you're a long way to helping the body look after itself.

What conditions require respiratory therapy?

Respiratory therapy is used in the treatment of breathing disorders. Some such disorders include asthma, COPD, emphysema, and bronchitis.

What is manual artificial respiration?

Artificial respiration is the act of assisting or stimulating respiration, a metabolic process referring to the overall exchange of gases in the body by pulmonary ventilation, external respiration, and internal respiration. In the field of manual artificial respiration, a general crystallization of ideas occurred several years ago as a result of extensive research on adult human subjects.

The features of alveoli?

well, it increases the surface area of the lung

it is also wrapped with tiny blood vessels called capillaries which makes easier

for gases to diffuse to and from the body.

it is very thin and one cell thick

it has a excellent transport system

Why does the respiratory system need Cardiovascular system?

In simple terms, the respiratory system and the circulatory system rely on each other. The lungs bring the oxygen to the blood supply and the blood supply then sends the oxygen throughout the body to all the vital organs and tissues. The blood supply also picks up the leftover blood that has used up all its oxygen and brings it back to the lungs to start the process over again.

Advantages and disadvantages of anaerobic respiration?

An advantage of anaerobic respiration is that it does not need oxygen. A disadvantage is that only small amounts of energy are produced.

Is cycling good for your respiratory system how?

cycling it is good for the respiratory system cycling it is good for the respiratory system

When is wearing a mask most beneficial to healthy respiratory system?

When there are a lot of toxins in the air such as when there is a fire or if you are at a debris field.

It also helps when sweeping a dusty garage.

What is the part of the respiratory system that has tiny air bags?

ok, think of your lungs as a cluster of grapes hanging upside down. The smallest branches are called bronchioles . At the end of each bronchiole is an "air sac" called alveoli .

What is the function of the aveoli?

The function of the alveoli is to allow gas exchange with the blood and lungs. It takes in the carbon dioxide and then diffuses it.

Why does anaerobic respiration happen?

Anaerobic respiration occurs because aerobic respiratory only produces a small amount of ATP (2 ATP) and because oxygen is consumed quickly in tissues. Anaerobic respiration produces a high amount of ATP and is particulary important in tissues such as muscles during streneous exercise.
