  1. El MedioAmbienteCelular La Ciencia de La Vida

  2. Componentes del FEC • Gases • Alimentos • Desechos • Hormonas • Vitaminas

  3. Caracteristicas del FEC • Temperatura: • Poiquilotermos • Homeotermos • pH: • Acido • Neutro: 7 • Base

  4. SolucionesCelulares • Isotónica: Concentracionesigualdentro y fuera de la celular. La celula no guardanipierdeagua.

  5. SolucionesCelulares • Hipertonica:solucion mas concentrada afuera de la celula (FEC) que adentro, causa deshidratacion

  6. SolucionesCelulares • Hipotónica: menorconcentracionafueraqueadentro, se absorbeagua y presentatendencia a romperse (citolisis)

  7. Intercambio de Materiales • TransportePasivo: moviemiento de sustancias de mayor a menorconcentracion (difusion) • Osmosis: solvente se difunde • Dialisis: soluto se difunde

  8. Intercambio de Materiales • TransporteActivo: uso de energiaparatransporte de materiales • Importantepara el mantenimiento de la concentracion de los iones en el FEC
