You breathe 12 to 20 times per minute without thinking. But here is the cool part: You don't breathe because you need oxygen; you breathe because you need to get rid of carbon dioxide. When CO2 builds up in your blood, your brain screams, "Breathe now!"
The more you understand physiology, the more you realize your body is not a machine that randomly breaks. It is a resilient, self-healing, brilliantly balanced ecosystem.
No se puede hablar de fisiología sin mencionar la homeostasis. Es el concepto central de esta disciplina. Coined por el fisiólogo americano Walter Cannon en el siglo XX, se refiere a la capacidad de un organismo para mantener un entorno interno estable a pesar de los cambios en el entorno externo.
To keep things interesting, here are three physiological facts that sound fake but are true:
While the nervous system sends fast, targeted signals, the endocrine system sends slow, widespread signals via hormones. explores feedback loops: the hypothalamus-pituitary-adrenal (HPA) axis in stress response, insulin and glucagon in glucose metabolism, and thyroid hormones in metabolic rate. Diabetes mellitus, hyperthyroidism, and Cushing’s syndrome are classic physiological disorders of this system.
Dado que la vida es diversa y compleja, la fisiología se divide en múltiples subdisciplinas. Aquí detallamos las más relevantes:
