medulla oblongata, in the brain stem.
Medulla Oblongata
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.
Hyperventilation. In other words, consciously overriding your natural breathing rhythm set by the brainstem and physically breathing faster.

- 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.
