Respiratory System

The respiratory system includes the lungs and the airway. The questions in this category focus mainly on the anatomical and physiological processes associated with breathing.

Suppose you are playing softball and you are at bat then you hit a home run and race around the bases what is the effect of the increased activity on your breathing rate and heart rate explain why thi?

Your respiratory and circulatory systems start working harder with activity. Your breathing rate increases which provides more oxygen to the working muscles. This helps remove carbon dioxide waste. Your heart pumps faster and delivers more nutrients and oxygen to muscles.

What are some discoveries of the respiratory system?

this is a wierd question so im not gonna answer it. also use ur own brain. hahahaha mr. yeager is funny as a dream team teacher.

What is pespiration?

Perspiration is another name for sweat. Humans sweat to help cool their bodies down during very hot weather. This helps to maintain the internal body temperature of 98.6 degrees and prevent overheating.

What is the main function of the pharynx?

The main function of the pharynx is to provide a passageway for the respiratory and digestive tracts. The pharynx is also referred to as the throat. It houses the tonsils, the uvula, epiglottis and is the entrance way to the esophagus.

The pharynx or throat, allows common passageway for air into your lungs and food into your stomach. The pharynx has two roles. The upper part of the pharynx will only allow food to pass through, and the lower part of the pharynx allows air, fluids, and food to pass through.

Which upper respiratory bacterial infection is characterized by a paroxysmal?

A paroxysm is a sudden recurrence or intensification of signs and symptoms of a disease. In the case of the respiratory system the bacterial infection is known as pertussis, or whooping cough.

Where does blood go AFTER it leaves the pulmonary arteries?

Blood leaves the pulmonary artery and travels into the lungs. In the lungs the blood releases carbon dioxide and picks up oxygen.

What is the normal breathing rate of a healthy person?

Many literatures post slightly varying values, and is understandable due to the variations due to age, gender and even metabolism. That's why a better indicator of abnormal breathing rate is guaged by comparing against your baseline. However if you want to know the AVERAGE breathing rate for most healthy people, the range of 30 breaths per minute is accepted.

What does the bronchioles do in the respiratory system?

The bronchi are the tubes which carry air from the trachea to the inner recces of thelungs, where it can transfer oxygen to the blood in the alveoli. Two main bronchi, the right and left bronchus, branch off of the low end of the trachea in what is called the tracheal bifurcation. One bronchus extends into each of the right and left lung. The bronchi continue to divide into smaller passageways, called bronchioles, forming a tree- like network of branches which extends throughout the spongy

Does the diaphragm lie between the thoracic and abdominal cavities and assist us to breathe?

Yes, the diaphragm lies between the thoracic and abdominal cavities and assists us to breathe.

What kind of blood cells surround the alveoli?

Alveoli are covered with capillaries. The deoxygenated blood that has come into the lung through the arteries flows through these capillaries, getting rid of carbon dioxide and accepting oxygen from the air that has been brought into the alveoli by the bronchioles. The carbon dioxide travels back out of the alveoli, through the bronchioles, into the bronchial tube system, and out the trachea each time you exhale.

Why does air move in our out of your respiratory system?

Because if it all stays in then your body will keep in this posions gass.

Does the gas exchange function of the respiratory system occur in the alveoli?

Yes gas is transferred through the alveolar/capillary membrane in the alveolus. Gas moves from the alveolar air sacs to the pulmonary capillaries.

What is a respiratory substrate?

Respiration is oxidation of foods, a catabolic process in living cells which liberate energy for this purpose of liberation of energy the compond used or oxidised is called respiratory substrate. Carbohydrates are preffered as respiratory substrate but some times protein and fat also play the role of respiratory substrate

Why is diaphragmatic breathing important?

I think that diaphragmatic breathing is when you breathe using your diaphragm, which causes your abdomen to go in and out. If you don't use your diaphragm, your chest expands instead. If you breathe with your diaphragm, you breathe more deeply.

What are effects of breathing WD40?

Not much. If you inhale a lot maybe just a feeling of light headedness. In that case go somewhere with fresh air and ventalate the area you sprayed.

"INHALATION: High concentrations may cause nasal and respiratory irritation and central nervous system effects

such as headache, dizziness and nausea. May aggravate existing respiratory conditions such as asthma. Intentional

abuse may be harmful or fatal."

Why our body cells have a different oxygen concentration compared to the blood flowing to them from our lungs?

Diffusion from high concentration to low concentration.

  1. The oxygen concentration in the air in the lungs is higher than in the blood.
  2. The oxygen concentration in the blood is higher than in body cells.
If these differences in concentration did not exist oxygen could not move from the air to the blood to body cells. While we are alive body cells consume some of the oxygen they receive, reducing their oxygen concentration and maintaining these differences.

When we die the body cells quit consuming oxygen and over a period of time the levels of oxygen slowly begin evening out (however as blood no longer moves from the lungs to the body oxygen diffusion slows dramatically, leaving some body cells with much lower oxygen levels than would be normal).

What is the study of parts of the throat called?

Otolaryngologists manage and treat disorders of the neck and head, including ears, nose, throat, sinuses, larynx and other structures
