V\u00fccudumuzdaki t\u00fcm i\u015flevler oksijen a\u00e7\u0131s\u0131ndan zengin kan\u0131 ihtiya\u00e7 duyulan b\u00f6lgeye y\u00f6nlendiren atardamarlara ba\u011fl\u0131d\u0131r. Atardamarlardaki d\u00fcz kas h\u00fccreleri, kan\u0131n hedefe ne kadar h\u0131zl\u0131 veya yava\u015f g\u00f6nderilece\u011fini ayarlar. D\u00fcz kaslar kas\u0131ld\u0131\u011f\u0131nda atardamarlar daral\u0131r, kan bas\u0131nc\u0131 y\u00fckselir; kas gev\u015fedik\u00e7e bu durum tersine d\u00f6ner, atardamar geni\u015fler ve kan bas\u0131nc\u0131 d\u00fc\u015fer. Kan bas\u0131nc\u0131 \u00e7ok d\u00fc\u015f\u00fckse, kan ak\u0131\u015f\u0131 v\u00fccudu oksijen ve besinlerle beslemek i\u00e7in yeterli olmayacakt\u0131r.

Kan bas\u0131nc\u0131n\u0131n ayarlanmas\u0131nda belirli maddelerin \u00f6nemli i\u015flevleri bulunur. Potasyum, kandaki kalsiyum oran\u0131n\u0131 d\u00fczenler. Kalsiyum ise, kan bas\u0131nc\u0131n\u0131 y\u00fckseltir, damarlar\u0131 daraltarak kan ak\u0131\u015f\u0131n\u0131n k\u0131s\u0131tlanmas\u0131na neden olur. Endotel h\u00fccreleri ve duyu sinirleri de d\u00e2hil olmak \u00fczere kan damar\u0131n\u0131 \u00e7evreleyen di\u011fer h\u00fccreler de kas i\u00e7erisinde kalsiyum ve potasyumun d\u00fczenlenmesine yard\u0131mc\u0131 olur.<\/p>\n

Nature Communications<\/em>‘da yay\u0131nlanan \u00e7al\u0131\u015fma ise \u00e7inkonun v\u00fccutta d\u00fc\u015f\u00fck kalsiyum seviyelerine yol a\u00e7t\u0131\u011f\u0131n\u0131 g\u00f6sterdi. \u00c7inko damar i\u00e7erisindeki kas\u0131n gev\u015femesine, kan bas\u0131nc\u0131n\u0131n d\u00fc\u015fmesine ve kan ak\u0131\u015f\u0131n\u0131n artmas\u0131na neden olmaktad\u0131r.
