What are the factors affecting the rate of diffusion? If one had to invent an answer to the question, one might sensibly intuit that increased work by muscles leads to an increased rate of metabolism which then increases the production of COIn short, they removed most of their brains and then stimulated their diencephalon locomotor regions to make these cat-zombies walk on treadmills. The relationship between PaCO 2 is fairly linear in the range of 45-80 mmHg; the rate of minute volume increases by 2-5L/min per every 1mm Hg of CO 2 increase. However, the activity of the respiratory centers can be influenced by these factors: What environmental factors control the breathing rate? Voluntary control. Factors that can cause a low respiration rate include: Drug overdose : An overdose of certain drugs, such as narcotics, can depress the breathing drive in the brain leading to low respiration rates. Control of breathing. The increase in the temperature increases; the rate of respiration gets doubled or tripled. Breathing is an automatic and rhythmic act produced by networks of neurons in the hindbrain (the pons and medulla). Whether caused by a virus or bacteria, these diseases can cause inflammation of your airways and excess production of mucus, making it difficult to breath. Neurochemical control of breathing.
