Isangqa esipheleleyo sokujikeleza kwegazi - umyinge wama-27 seconds. Kwiinkqubo zeempahla zegazi, iimpahla zamanzi kunye neendawo ezinobungozi ziyahluka. I-arterial enkulu kakhulu yi-aorta. Iyadlula kwimibhobho emikhulu, eyahlukana ibe yimibhobho encinci, ngoko "ukugeleza" kwii-arterioles zincinci kwaye zigqitywe ngamancinci amancinane. Ububanzi bawo buyi-5-10 micrometer kuphela. Iinqanawa ezincinci ziphathiswe umsebenzi omkhulu-zondla izicubu nge-oxygen kwaye zinoxanduva lwe-metabolism. Ama-Capillaries emzimbeni womntu kangangokuthi ukuba ubaqokelela ndawonye kwaye uyakhele ubude - malunga nama-2.5 amaxesha ajikeleze i-equator! Indlela yokomeleza imithwalo yegazi emzimbeni womntu, oku kuya kuxutyushwa kwinqaku.
Isistim sezinambuzane siqala kunye nama-capillary amancinci amancinci (athabatha iimveliso zeselluliyam iselula ukusuka kwiiseli, edlula kwii-vets aze afike kwiinqanawa ezinkulu apho igazi libuyela entliziyweni ukuqala umjikelezo omtsha). Inxaxheba ekhethekileyo emzimbeni womntu unikezelwa kwinkqubo ye-lymphatic. I-lymph ihlamba zonke iiseli kunye nezicubu zomzimba, yenza imisebenzi yokucoca kunye nokuhlanjululwa (ukungathathi i-neutralization, ingcats bacteria, ii-virus, ii-particle zangaphandle). Xa kungekho kuphazamiseka "kumbhobho wamanzi" oyintloko, zonke iiseli zifumana umlinganiselo ofanelekileyo we-oksijeni, igazi lihlambuluke ngokupheleleyo kwaye lifika entliziyweni ngexesha. Esi sibambiso sokubonakala kakuhle (ngokwenene, umzimba wonke ufumana izondlo, kuquka isikhumba!) Nokulondolozwa kwempilo. Hayi, kukho ukungaphumeleli kwiinqanawa.
Atherosclerosis
Olu lwakhiwo kwiindonga zeempahla zamathala. Bahamba ngokukhawuleza okanye bagubungele ngokupheleleyo i-lumen kwaye baholele kwindlala ye-oksijini yesikhumba. Iiplati ezinomthamo zingabangela ukuhlaselwa yintliziyo okanye ukubetha - kuxhomekeka apho isitya esikhankanywe khona. Ukususela kwi-atherosclerosis kwindawo yokuqala kuza kugcina ukutya okunokulinganisela. Emva kwakho konke, iiplati kwiimitha ze-arteries zilibazisekile ngenxa ye-cholesterol engaphezulu. Kufanelekile ukumemela imifuno, iziqhamo, amaqabunga amaqabunga, iintlanzi ezinamafutha ukuze kudle. Zityebi kwiipolunsaturated acid acids, neempahla eziyimfuneko kakhulu. Inyama kufuneka idliwe ngokulinganiselayo, ngokukhethekileyo inyama yenkomo, inyama yengulube, inyama yenkukhu emhlophe. Ingcamango yokuba abantu emva kweminyaka engama-45 ukuya kwe-50 kufuneka bayeke inyama yezidlo - ezimbi. Abanye abemi bavame ukunyamezela i-steaks kunye ne-chops-inani le-cholesterol ayinyuli. Kodwa kucetyiswa ukuba uxoxe ngemenyu yakho kunye nesondlo sokutya. Futhi ukulawula izinga le-cholesterol - ngenxa yale njongo yokuhlolwa kwegazi okhethekileyo kwenziwa. Ngendlela, kukho amahemuhemu ukuba imivenge yegazi ihlambuluke. Iingcali zeCardiologists ziphikisa le ngqungquthela. I-plumber yenkqubo yethu yokunikezelwa kwegazi, alas, ayikwazi ukubizwa. Ukususela kwizifo, iinqwelo ziya kukhululeka ngokuhlinzwa okanye imishanguzo - njengoko ugqirha uyonyula!
Thrombosis
Ngenxa yokuqhekeka kwezihlunu kunye neepavini zomoya, ukuhamba kwegazi ngeemvini kuhlale kuqhutyelwe phezulu. Ukuba iiplavines ezivuthayo zihluleka ukusebenza, ukungafihleki okungapheliyo kubonakala, okungaba nzima ukubunjwa kwe-thrombi. Ingakumbi i-insidious (floating clots clots). Azinamathele ngokuqinile kwiindonga zeempahla. Baya kuhamba baze basondele entliziyweni. Iimpawu eziphambili zesifo: ubunzima kunye nentlungu emilenzeni, ukuvakala, ukuxubha, intlungu emlanjeni, ukutshisa, iimbandezelo zobusuku, ukubetha, ukubonakala kwintambo yomnatha. Isifo sesifuba sisoloko sibizwa ngokuba sisifo sobugcisa bezinwele, abathengisi kunye nabasebenzi be-ofisi - abo bachitha ixesha elide okanye bahlale. Ngaphantsi naziphi na iimeko, imilenze kufuneka ihambe. I-Gymnastics, ibhayisikili, ukudansa, ukubhukuda yimidlalo emihle kwimpilo ye-vascular. Kubalulekile ukukhusela imithombo yokushisa, okubangela ukwandiswa kweemvini (ukhethe ukunyuka kwamaqondo ashushu). Kubalulekile ukumisela amathumbu kwaye ulungelelanise ubunzima. Kwakhona, ungagqoki itekisi, ucaze iingubo kwaye ufumane izicathulo ezifanelekileyo.
Ukukhupha
Xa i-microcirculation iphazamiseka kwiinqanawa ze-lymphatic, i-edema ibonakala, ukubonakaliswa kwayo okugqithiseleyo kukuthi "i-elephantiasis" (ukuvuvukala kwemilenze).
Ziyingozi
- Ukubhema - kubangelwa imida yegazi.
- Utywala. Nangona utywala oluncinane lotywala kunye nokwandisa imirhoxo, ukunciphisa izinga le-cholesterol, izazi ze-cardiologists azicebisi ukuba zisebenzise iprophylaxis enjalo. Kukho umngcipheko wokulutha nokuxhomekeka.
- Ukugxininisa - yenza iinqanawa ziphazamise kwaye zenzeke.
Usefull
- Ukuhamba-ukuhamba kweyure kathathu ngeveki kunzima ukukhupha iimpahla.
- Ukuthobeka - fundisa iifostile ekuphatheni iimeko ezingalindelekanga.
- Imifuno yemifuno kunye neentlanzi zaselwandle - ziqulethe ezininzi i-polyunsaturated fatty acids, ezomeleza kwaye zandisa ukwanda kweempahla.
