  2. CALCITONINA 1 En células parafoliculares del TIROIDES. Disminuye los niveles de Ca2+en sangre. PARATOHORMONA 2 En PARATIROIDES. Aumenta los niveles de Ca2+en sangre.

  3. CALCITONINA en: células parafoliculares (1). Células foliculares (2): Células parafoliculares (3): Coloide (tiroglobulina)

  4. CALCITONINA FUNCIÓN: controla los niveles de calcio Activa osteoblastos Ca2+en sangre. Inhibe osteoclastos ANTOGONISTA: paratohormona (PTH) Ca2+en sangre. inhibe la

  5. PARATOHORMONA (PTH) en: PARATIROIDES

  6. PARATOHORMONA (PTH) RIÑÓN (absorbe Ca2+ a la sangre) órganos diana HUESO (libera Ca2+ a la sangre) Ca2+en sangre. CÉLULAS INTESTINALES (absorbe Ca2+) actúa sobre gracias a VITAMINA D exceso Osteitis fibrosis quística
