Aquesta setmana hem realitzat un experiment molt interessant per comprendre millor com funciona el cor i el sistema circulatori<\/strong>.<\/p>\n

Primer hem apr\u00e8s que l\u2019aparell circulatori \u00e9s el sistema encarregat de transportar la sang per tot el cos. Est\u00e0 format pel cor<\/strong>, els vasos sanguinis<\/strong> i la sang<\/strong>. El cor funciona com una bomba: es contrau i es relaxa constantment per impulsar la sang cap als pulmons i cap a la resta del cos. Aquest moviment r\u00edtmic \u00e9s el que hem volgut representar amb el nostre experiment.<\/p>\n

Per construir el model hem utilitzat un pot de vidre transparent, palletes, globus, aigua i colorant vermell per simular la sang. Hem omplert el pot fins a la meitat amb aigua tenyida de vermell. Despr\u00e9s, hem col\u00b7locat les palletes a la tapa (o a la boca del pot) i hem segellat b\u00e9 els espais amb plastilina perqu\u00e8 no entr\u00e9s aire.<\/p>\n

A continuaci\u00f3, hem tallat un globus i l\u2019hem col\u00b7locat ben tensat sobre la boca del pot, simulant una membrana flexible. Aquest globus representava el moviment del cor.<\/p>\n

Quan pression\u00e0vem el globus i el deix\u00e0vem anar suaument, hem pogut observar com el l\u00edquid es movia a trav\u00e9s de les palletes. D\u2019aquesta manera, hem simulat com el cor impulsa la sang pels vasos sanguinis cap a tot el cos.<\/p>\n

Aquest experiment ens ha ajudat a entendre, de manera visual, com el cor funciona com una bomba imprescindible per a la nostra vida.<\/p>\n

Us deixem algunes fotos:<\/p>\n
