Factors that influence the rate and depth of breathing include _____. Gas exchange: the process of getting oxygen (O2) into the body and carbon dioxide (CO2) out. It supplies oxygen for a process called cellular respiration, which is how cells manufacture the energy they need for their life functions. Before the end of inhalation, there is a decline in, and end of motor discharge. e) all of these. Blood pH -- a reflection of its relative acidity or alkalinity -- also influences respiratory rate. Where does the respiratory zone of the lungs... What are the parts of the respiratory zone? Respiratory illnesses are one of the factors that affect breathing rate. Human tend to breath at a respiratory rate close to the one that minimises work of breathing. Breathing is normally an unconscious, involuntary, automatic process. Stress – stress increases the heart rate due to adrenaline/epinephrine release. Another factor involved in influencing the respiratory activity of the brain is systemic arterial concentrations of hydrogen ions. The respiratory rate and the depth of inspiration are regulated by the medulla oblongata and pons; however, these regions of the brain do so in response to systemic stimuli. Breathing is a necessary function for human beings. If a disorder reduces the tidal volume the respiratory rate increases to compensate and vice versa. Most notably, PaCO2 influences the minute volume (i.e. There is an increase in the breathing rate, this is due to the demand for oxygen from the working muscles.
