     • The respiratory rate is the total number of breaths, or respiratory cycles, that occur each minute. Respiratory rate can be an important indicator of disease, as the rate may increase or decrease during an illness or in a disease condition.

   What is the difference between respiratory capacity and respiratory rate?

   • Respiratory capacity is the combination of two or more volumes. Anatomical dead space refers to the air within the respiratory structures that never participates in gas exchange, because it does not reach functional alveoli. Respiratory rate is the number of breaths taken per minute, which may change during certain diseases or conditions.

   How is respiratory rate controlled?

   • Respiratory rate is controlled by the respiratory center, located in the medulla oblongata. Conscious thought can alter the normal respiratory rate through control by skeletal muscle, although one cannot consciously stop the rate altogether. Atypical resting respiratory rate is about 14 breaths per minute.

   What is respiratory rate & depth?

   • Respiratory rate is the number of breaths taken per minute, which may change during certain diseases or conditions. Both respiratory rate and depth are controlled by the respiratory centers of the brain, which are stimulated by factors such as chemical and pH changes in the blood.

   How A respirometer is used to measure the rate of respiration?

   • Respirometers are used to measure the rate of respiration. The diagram shows equipment set up which is being used to measure the respiratory rate of an insect. The higher the rate of respiration, the more the coloured liquid moves. The experiment has a control with no insect in order to compare results.

   What is respiratory volume?

   • Respiratory volume is the term used for various volumes of air moved by or associated with the lungs at a given point in the respiratory cycle. There are four major types of respiratory volumes: tidal, residual, inspiratory reserve, and expiratory reserve (Figure 4). Figure 4.

   How does the hypothalamus regulate respiration?

   • The hypothalamus and other regions associated with the limbic system are involved in regulating respiration in response to emotions, pain, and temperature. For example, an increase in body temperature causes an increase in respiratory rate. Feeling excited or the fight-or-flight response will also result in an increase in respiratory rate.

   Breathing In. The breathing-in process causes the volume in the chest to increase and the air pressure in the lungs to decrease until it is slightly lower than the atmospheric pressure; As a result, air moves down the pressure gradient and rushes into the lungs; Mechanism when at rest: The diaphragm contracts and flattens, increasing chest volume

   Breathing rate should be given in breaths min⁻¹ (breaths per minute), so the breathing rate during the first minute = 12 breaths min⁻¹. Step Three: Count the number of breaths in the second 60 seconds. There are 14 breaths in the second 60 seconds. Step Four: Give appropriate units.
