Isiyingi esigcwele sokujikeleza kwegazi - isilinganiso samasekhondi angu-27. Esikhathini sesistimu yezindwangu zegazi, izitsha ze-arterial and venous zihlukile. Isigaba esikhulu kunayo yonke i-aorta. Idlula emithanjeni emikhulu, ehlukaniswa ibe yi-arteries encane, bese "ukugeleza" ibe yi-arterioles encane nakakhulu futhi iphele ngamancinci amancane kakhulu. Ububanzi bawo buyi-5-10 micrometer kuphela. Izitsha ezincane zinikezwe umsebenzi omkhulu - zondla izicubu nge-oksijeni futhi zibhekene nokusetshenziswa kwesimiso somzimba. Ama-Capillary emzimbeni womuntu kangangokuthi uma uwaqoqa ndawonye futhi uwade ubude - cishe izikhathi ezingu-2.5 ukuguqula i-equator! Indlela yokuqinisa imithwalo yegazi emzimbeni womuntu, lokhu kuzoxoxwa ngakho kulesi sihloko.
I-systemous venous iqala ngama-capillary ama-venous amancane kakhulu (athatha imikhiqizo ye-metabolism yeselula esuka kumaseli, edluliselwa ezigodini bese efika ezitsheni ezinkulu lapho igazi libuyela enhliziyweni ukuqala umjikelezo omusha). Indima ekhethekile emzimbeni womuntu inikezwa ohlelweni lymphatic. I-lymph ihlamba wonke amangqamuzana namazimba omzimba, yenza imisebenzi yokucwenga nokuhlanza (i-neutralization, amabhaktheriya angenayo, ama-virus, izinhlayiya zangaphandle). Uma kungekho ukuphazamiseka "emgqeni wamanzi" wethu oyinhloko, wonke amangqamuzana athola isilinganiso esifanele se-oxygen, igazi lihlanzwa ngokuphelele futhi lifika enhliziyweni ngokuhamba kwesikhathi. Lokhu yisibambiso sokubukeka kahle (empeleni, umzimba wonke uthola izakhi, kufaka phakathi isikhumba!) Nokulondolozwa kwempilo. Maye, kukhona ukwehluleka kulezi zitsha.
I-aestrosclerosis
Lokhu kwakheka ezindongeni zezitsha zamapulethi. Zihlanganisa noma zimboze ngokuphelele i-lumen yazo futhi ziholele ekwenzeni i-oksijini indlala yamathishu. Ama-plaques ase-arteries angabangela ukuhlaselwa kwenhliziyo noma isifo sokushaya - kuncike lapho umkhumbi ovaliwe khona. Ukusuka kokutholakala kwesifo sokuqina kwamathambo endaweni yokuqala kuyosindisa ukudla okunomsoco. Phela, ama-plaque emithanjeni aphuza ngenxa ye-cholesterol eyengeziwe. Kufanelekile ukumemela imifino, izithelo, amaqabunga amaqabunga, izinhlanzi ezinomsoco ukuze kudle. Bacebile kuma-acids amaningi e-polyunsaturated, izitsha ezidingekayo kakhulu. Inyama kufanele idliwe ngokulinganisela, mhlawumbe yenkomo endala, inyama yengulube, inyama yenkukhu emhlophe. Umbono wokuthi abantu emva kweminyaka engama-45-50 kufanele bayeke ukudla okumnandi inyama - okungalungile. Izakhamizi ezithile zivame ukubekezelela ama-steaks kanye nama-chops - inani le-cholesterol alinyuli. Kodwa kunconywa ukuxoxa ngemenyu yakho nomuntu odla ukudla okunomsoco. Futhi ukulawula izinga le-cholesterol - ngale njongo ukuhlolwa kwegazi okhethekile kwenziwa. Ngendlela, kunamahemuhemu ukuthi imithwalo yegazi ingasulwa. Izazi ze-cardiologists ziphikisa le myane. I-plumber ye-system yethu yokunikezwa kwegazi, alas, ayikwazi ukubizwa. Kulezi zifo, izitsha zizokhululeka ngokuhlinzwa noma imithi - njengoba udokotela eyoyiqoka!
I-Thrombosis
Ngenxa yokwehlukaniswa kwemisipha kanye namagagasi e-venous, ukuhamba kwegazi emithanjeni kuhlale kuqondiswa phezulu. Uma ama-valve enamafutha ahluleka ukusebenza, ukungakwazi ukuphefumula okungapheli kubonakala, okungaba nzima ukubunjwa kwe-thrombi. Ngokungaqondakali ikakhulukazi kukhona ukuhamba (ukuphazamisa ama-blood clots). Azinamathele ngokuqinile ezindongeni zezimpahla. Bangakwazi ukuhamba basondele eduze kwenhliziyo. Izibonakaliso eziyinhloko zesifo: ubunzima nobuhlungu emilenzeni, inzwa yokuzikhukhumeza, ukuxubha, ubuhlungu phakathi komvuthwandaba, ukuvutha, ukukhwabanisa ebusuku, ukuchithwa, ukubonakala kwenethiwekhi enobuhlungu. Isifo se-vein ngokuvamile sibizwa ngokuthi yisifo sochwepheshe sabadayisi bezinwele, abathengisi kanye ... abasebenzi basehhovisi - labo abachitha isikhathi esiningi noma bahlale. Ngaphansi kwanoma yiziphi izimo, imilenze kufanele ihambisane. Ukuzivocavoca, ukuhamba ngebhayisikili, ukudansa, ukubhukuda kuyimidlalo enhle yempilo ye-vascular. Kudingekile ukugwema imithombo yokushisa, okubangela ukwandiswa kwemithanjeni (ukhethe ukushisa okuphansi). Kudingekile ukuba uhlalise amathumbu futhi ugcine isisindo. Futhi, ungagqoki isicikilisi, ucindezela izembatho bese uthola izicathulo ezifanele: ukuyeka izintambo eziphansi kanye nezithende ezingaphezu kuka-5 cm.
I-Puffiness
Uma i-microcirculation iphazamiseka ezenzweni ze-lymphatic, i-edema ibonakala, ukubonakaliswa kwayo okudlulele "i-elephantiasis" (ukuvuvukala kwemilenze).
Kuyingozi
- Ukubhema - kubangela ukuqhuma kwemithambo yegazi.
- Utshwala. Nakuba udoti oluncane utshwala futhi ukwandisa imithwalo yegazi, ukunciphisa izinga le-cholesterol, izazi ze-cardiologists musa ukululeka ukusebenzisa i-prophylaxis enjalo. Kukhona ingozi yokulutha nokulondeka.
- Ukucindezeleka - yenza izitsha ziphaphatheke futhi zihlume.
Sebenzisa
- Ukuhamba - ukuhamba kwehora ngehora kathathu ngesonto kunzima kakhulu izitsha.
- Ukuthula - funda ukufihla ngokufihliwe ngefilosofi izimo ezingalindelekile.
- Imifino yemifino nezinhlanzi zasolwandle - ziqukethe ama-acids amaningi e-polyunsaturated, aqinisa futhi akhulise ukuqina kwezimpahla.
