The rhythmicity of breathing is primarily controlled by the brainstem, particularly the medulla oblongata and pons. Neurons in these areas generate rhythmic patterns of activity that regulate the contraction of respiratory muscles. Additionally, sensory input from chemoreceptors and mechanoreceptors helps modulate the rhythm based on the body’s metabolic needs, such as changes in carbon dioxide and oxygen levels. This complex interplay ensures that breathing remains automatic yet adaptable to various physiological demands.

working on my circadian rhythmicity
The heart is the only organ containing cardiac muscle
there is a specific group of cells found in the medula (part of the brain stem) which regulate the rhythm of breathing, hence the name (of this cellular formation) the Medulary Rhythmicity Center.

by breathing in lots of spores from the soil.
- rhythmicity : capability of rhythmic self-excitation therefore no need for external control -conductivity: conduction of action potential along specialised muscle cells. -excitability: ability of muscle fibers to get exited . -contractility; ability of cardiac muscle to contract . It also has a long refractory period meaning it cant tetanus

A goldfish's breathing rate can be determined by counting the amount of times the goldfish opens and closes its mouth within a set amount of time, ex. 92 breathes per minute.
The longest time someone has stayed underwater without a breathing aid is 24 minutes and 3.45 seconds. This record was set by Aleix Segura Vendrell in 2016.
Yes respiratory therapists are there to help you set up a bipap machine (A BIPAP machine is a type of ventilator used to treat chronic conditions that affect your breathing.) But you have an option to set it up yourself.
