In reference to the Hering-Breuer reflex, which of the following statements is accurate? The Hering-Breuer reflex is responsible for preventing the lungs from becoming too distended. With the action of central chemoreceptors, an increase in the concentration of hydrogen ions will result in an rise in the tidal volume.
In reference to the Hering-Breuer reflex, which of the following statements is true?
The right response
The Hering-Breuer reflex is responsible for preventing the lungs from becoming too distended. If there is a rise in the concentration of hydrogen ions, then there will be a corresponding rise in the tidal volume that is sensed by the central chemoreceptors.
What exactly takes place during a Hering-Breuer reflex?
Expansion of the lungs activates stretch receptors in the airways, which in turn causes the Hering-Breuer reflex to be triggered. The stimulation of these receptors, which send signals to the medulla by way of the vagus nerve, shortens inspiratory periods as tidal volume (the volume of air inspired) increases, which in turn accelerates the frequency of breathing.…
The Hering-Breuer reflex quizlet seeks to answer the following question:
The Hering-Breuer reflex is characterized by a reduction in the frequency of inspiratory effort that occurs as a direct response to prolonged pulmonary distention. It is believed that this reduces the amount of effort required for breathing by preventing excessive tidal volumes. It is believed that this will prevent an excessive distention of the alveoli under high tidal volumes.
Which component of the upper respiratory system is responsible for maintaining a constant pressure level inside the middle ear?
The eustachian tube is a canal that connects the middle ear to the nasopharynx, which is made up of the upper part of the neck and the back of the nasal cavity. The nasopharynx is located behind the nose. It regulates the pressure that is present in the middle ear, bringing it into equilibrium with the air pressure that is present beyond the body.

We found 35 questions connected to this topic.
How exactly does the eustachian tube regulate the pressure in the middle ear?
The back of the nose and the top part of the throat are connected to the middle ear through a passage called the eustachian tube. When the eustachian tube is opened, either by swallowing or yawning, it is possible for air to flow into or out of the middle ear. This helps to bring the pressure on either side of the ear drum into a more even distribution.
When diving, how do you ensure that the pressure in each of your ears is equal?
The key to doing safe equalizing is to open the eustachian tubes, which are ordinarily closed, so that air may travel from the throat to the ears through the opening in the tubes. The majority of divers are instructed to equalize their pressure by pinching the bridge of their nose and gently breathing into their mouth. This mild pressure causes the eustachian tube to expand, allowing air to gently flow into the middle ear.
Why is it so vital for the nasal cavity to have its own blood supply?
Why is it so vital for the nasal cavity to have its own blood supply? Because of the dense vascularization in the nose, which transports heat from the body to the nasal cavity, the air that is inhaled is warmed before it is expelled from the nose. Moreover, the heat causes the moisture present in the epithelium to evaporate, which in turn humidifies the air that is being drawn in.
Which of the following statements best represents the tidal volume of a client?
Which of the following statements best represents the tidal volume of a client? A. The volume of air that is inhaled and exhaled with each breath is referred to as the tidal volume.
A quiz about the trachea: what is it?
Trachea. The term “windpipe” refers to the broad membranous tube that extends from the larynx to the bronchial tubes and is reinforced by rings of cartilage. This tube is responsible for transporting air to and from the lungs. Tree with Bronchial Trunks The network of bronchi and bronchioles that branch off from the windpipe and carry air to the lungs from the chest cavity.
What do irritant receptors do?
Irritant receptors are found in the spaces between airway epithelial cells and are activated when irritant gases, cold, or inhaled dusts are present. After being triggered, they will send action potentials via the vagus nerve, which will ultimately result in bronchoconstriction and an increased respiratory rate.
What does it mean to have a Breuer Lockhart reflex?
Laryngospasm, Bronchospasm, Bradycardia, and even Cardiac Arrest can be caused by Mild Anaesthesia During Lord’s (Anal) Stretching and Cervical Dilatation. The Breuer Lockhart Reflex is the name given to this particular reflex.
Which centers have the responsibility of preventing the lungs from becoming overinflated?
The Hering-Breuer reflex is responsible for preventing the lungs from becoming overinflated. This reaction is triggered by nerve receptors located in the walls of the bronchi and bronchioles, which then communicate with the dorsal respiratory center via the vagus nerve. The reflex turns off excessive inflating when the patient is inspired, and it turns off excessive deflation when the patient is exhaled.
In terms of the dorsal and ventral respiratory groups, which of the following assertions is the most accurate?
In terms of the dorsal and ventral respiratory groups, which of the following assertions is the most accurate? The nuclei of the dorsal and ventral respiratory groups act through a process known as reciprocal inhibition. The dorsal and ventral respiratory groups are responsible for determining the rate and rhythm of breathing.
Which of the following statements(s) most accurately describes(s) what takes place throughout the expiration quizlet?
Which of the following statements accurately explains what takes on during the expiry process? In order to restore the rib cage and diaphragm to their natural position, the external intercostal, pectoral minor, and sternocleidomastoid muscles gradually relax.
What is tidal volume quizlet?
tidal volume. the volume of air that enters and exits your lungs during a single cycle of calm regular breathing. reserve volume of the inspiration. the maximum amount of extra air that can be taken in after finishing an ordinary breath intake. volume available for expiration as a reserve.
What makes a excellent collection of inspired works?
The average capacity of the inspiratory reserve in males is around 3000 mL, while the average volume in females is 2100 mL. Vital capacity. The whole volume of the lungs that can be used effectively and that can be controlled. Because it is physically impossible to actively expel all of the air from one’s lungs, this number does not represent the whole volume of the lungs.
What is the volume of the tidal range?
Tidal volume can be thought of as the sum total of all of a person’s breaths. One of the most important factors that determines minute ventilation and alveolar ventilation is this factor. A measurement of the amount of air that enters the lungs on a minute-to-minute basis, minute ventilation (also known as total ventilation) is another name for this. It is calculated by multiplying the respiratory rate by the tidal volume.
Which of the following may be determined given only the tidal volume and the respiratory rate?
Computation of minute volume
When the tidal volume (VT) and the respiratory rate ( or RR) are known, it is possible to compute the minute volume by multiplying the tidal volume and the respiratory rate.
What specific chemical components found in blood or cerebrospinal fluid are responsible for stimulating the respiratory centers?
What specific chemical components found in blood or cerebrospinal fluid are responsible for stimulating the respiratory centers? The respiratory centers are stimulated by the pH, Po2, and Pco2 levels that are present in blood and cerebral fluid.
What kind of function do the tracheal cartilages that are fashioned like a C allow?
After food is swallowed, it is able to travel down the esophagus because the trachea has C-shaped cartilaginous rings that allow it to compress slightly at its opening. During the process of swallowing, the epiglottis will pull back and cover the opening to the larynx. This will prevent anything that is ingested from going into the trachea.
What exactly is equalization diving all about?
“Equalizing” is a term used in scuba diving, and it refers to the process of adjusting the pressure in your ears so that it is comparable to that of the surrounding water. Nevertheless, the human body is not well adapted to the kind of environment that exists underwater, which means that the ears will struggle to maintain balanced pressure the deeper you go.
When is the appropriate time to equalize your ears?
When to Reach an Equilibrium
The majority of authorities agree that every two feet of drop should be equalized. This means that there is an equalization every two seconds when the descent rate is a relatively sluggish 60 feet per minute. A significant number of divers fall at a significantly faster rate and should always be equalizing.
How exactly does the ear Equalization function?
Equalization is the process by which the pressure in our middle ear is brought back into balance. This is accomplished by either increasing or reducing the gas pressure in an effort to match the pressure at depth. This takes place through the Eustachian tube, which is a passageway that links the middle ear to the nose.
