Omutima gwaffe kitundu kya mubiri ekyewuunyisa. Okuva ku lunaku lwe tuzaalibwa okutuuka ku lunaku lwe tufa, kikola awatali kuyimirira okumala sekondi emu. Okufaananako ne ppampu entegefu, ekuba omusaayi mu mubiri gwonna. Waliwo obutundutundu bungi obugiyamba okukola obulungi. Wali weebuuzizza engeri omusaayi gye gukulukuta mu ludda lumu lwokka munda mu mutima, nga tegukulukuta mabega? Ekyo "valves" mu mutima kye ziyambako. Leero twogera ku vvaalu emu ey’enjawulo bwetyo, vvaalu y’amawuggwe.
Mu ngeri ennyangu, vvaalu y’amawuggwe kye ki?
Kuba akafaananyi ng’omutima gwo gulina ebisenge bina. Babiri waggulu ate babiri wansi. Valiva eno ey’amawuggwe eringa omulyango ogugenda mu kkubo erimu wakati w’ekisenge ekya wansi ku ludda olwa ddyo olw’omutima (omusuwa ogwa ddyo) n’omusuwa omukulu ogutwala omusaayi mu mawuggwe (omusuwa gw’amawuggwe) .
Omulimu gwayo omukulu kwe kufuga okutambula kw'omusaayi "omucaafu", ogubadde gukozesebwa mu mubiri gwaffe era nga gulimu oxygen mutono, okuva ku mutima okutuuka mu mawuggwe okusobola okulongoosa. Omusaayi bwe gumala okuyita, ekikomera kino kiggalwawo okulemesa okukulukuta okudda mu mutima.
Valiva eno ey’amawuggwe, awamu ne vvaalu y’omusuwa gw’omusuwa ku ludda olulala olw’omutima, byonna awamu biyitibwa “valvule za semilunar.” Kino kiri bwe kityo kubanga obupapula/ebipande ku vvaalu zino bifaanana ng’ekitundu ky’omwezi. Oluusi abasawo era kino bakiyita "pulmonic valve," ekintu kye kimu.
Valiva eno ekola etya? Kyewunyisa!
Engeri akaggi kano akatono gye kakolamu yeewuunyisa. Kiringa okuzina, okuggulawo n’okuggalawo mu nnyimba ezituukiridde n’okukuba kw’omutima.
- Systolic phase: Omusuwa ogwa ddyo bwe gukonziba, omusaayi oguli munda mu gwo gufuluma. Mu kiseera ekyo, vvaalu y’amawuggwe egguka . Oluvannyuma, omusaayi ogutaliimu mukka gwa oxygen guyingira mu musuwa gw’amawuggwe, ogugenda mu mawuggwe.
- Diastolic phase: Omutima bwe guwummulamu nga gumaze okukonziba, oba bwe guwummudde, vvaalu y’amawuggwe eggalawo nnyo . Singa teggalawo, omusaayi ogusindikibwa mu mawuggwe guyinza okukulukuta okudda mu mutima. Valiva eno eremesa ekyo okubaawo. Valiva eno bw’eggalwa, ventricle eya ddyo n’ejjula omusaayi okupampagira lawundi eddako.
Mu ngeri ennyangu, kiringa omuserikale w’ebidduka ku luguudo. Aleka omusaayi okutambula mu ludda lumu lwokka n’aguyimiriza ddala okudda emabega.
Enkozesa ey’enjawulo: Enkola ya Ross
Ng’oggyeeko enkola ya vvaalu eno eya bulijjo, era ekozesebwa ku kigendererwa ekirala ekyewuunyisa: vvaalu y’omusuwa esinga obukulu mu mutima bw’efuna obulwadde, vvaalu eno ey’amawuggwe eteekebwa mu kifo ky’ekyo.
Kino kiyitibwa enkola ya Ross. Enkola esingako okukaluba katono. Mu nkola eno, omusawo alongoosa aggyawo vvaalu yo ey’omusuwa omulwadde n’agikyusa n’agiteekamu vvaalu yo ey’amawuggwe ennungi. Olwo, vvaalu y’amawuggwe eya donor esimbibwa mu kifo vvaalu y’amawuggwe we yali. Olw’okuba ye tissue yo, ekwatagana bulungi era ewangaala.
Endwadde ki ezikosa vvaalu eno?
Ebiseera ebisinga, obuzibu ku vvaalu y’amawuggwe bukwatagana n’embeera z’omutima ezizaalibwa . Kino kitegeeza nti omwana asobola okufuna ebizibu bino ng’azaalibwa. Tekitera nnyo, obuzibu ku vvaalu eno busobola okubaawo oluvannyuma lw’obulamu olw’embeera endala ez’obujjanjabi (okugeza, puleesa y’amawuggwe).
Ka tutegeere embeera zino enkulu ez’obujjanjabi okuva ku kipande wansi.
| Kakwakkulizo | Mu ngeri ennyangu, kino kye kibaawo... |
|---|---|
| Obulwadde bw’amawuggwe obuyitibwa atresia | Eno mbeera ya buzaale. Ekibaawo wano nti vvaalu y’amawuggwe tekula bulungi. Kiringa bbugwe azimbibwa we wandibaddewo oluggi. Omusaayi tegusobola kutuuka mu mawuggwe. Kino kiyinza okuvaako omwana okufuuka bbululu (cyanosis) ng’azaalibwa. |
| Tetralogy ya Fallot | Buno era bulwadde bwa mutima obuzibu obuzaalibwa nabwo. Wano, obulema bw’omutima buna bubaawo awamu. Ekimu ku bizibu ebyo kwe kufunda kw’ekisenge ky’amawuggwe n’omusuwa gw’amawuggwe. Olw’okuba eno embeera ya maanyi, omwana ajja kuba alina okulongoosebwa okugitereeza. |
| Okusannyalala kw’obusuwa bw’amawuggwe | Ekibaawo wano kwe kuba nti ekifo we baggulawo vvaalu kifunda. Olwo omutima gulina okukola ennyo okufulumya omusaayi. Emirundi egisinga kino nakyo kintu ekibaawo ng’azaalibwa. Abantu abamu balina obujjanjabi okugaziya vvaalu, ate abalala balina okukyusa vvaalu. |
| Valiva y’amawuggwe etaliiko | Eno embeera etatera kubaawo nnyo, ezaalibwa. Mu mbeera eno, ebipapula bya vvaalu biyinza okubula oba obutakula bulungi. Kino kireetera vvaalu okufunda n’etaggalawo bulungi, ekivaako omusaayi okukulukuta emabega (regurgitation). |
| Okuddamu okufulumya amazzi mu vvaalu y’amawuggwe | Ekibaawo wano nti vvaalu teggalawo bulungi. N’olwekyo omutima bwe guwummulamu, omusaayi ogumu ogusindikibwa mu mawuggwe gukulukuta ne gudda mu kisenge kya ddyo. Kino tekiba kyangu mu bantu abasinga obungi. Naye mu mbeera enzibu, ventricle eya ddyo esobola okugaziwa n’enafuwa, era omubiri gusobola okujjula amazzi ne guzimba (edema). |
Kisoboka okubeera nga tolina vvaalu y’amawuggwe?
Eky'okuddamu ekitereevu mu kibuuzo kino kiri nti "nedda." Valiva y’amawuggwe kitundu kikulu nnyo mu lugendo lw’omusaayi gw’omubiri gwaffe okutuuka mu mawuggwe okufuna omukka gwa oxygen. Awatali vvaalu ekola obulungi, tetusobola kubeera balamu.
Naye ekintu ekisinga obukulu kye twetaaga okutegeera wano kiri nti olw’obujjanjabi obw’omulembe obw’ennaku zino, embeera zino zisobola okujjanjabibwa obulungi . Singa tebajjanjabwa, abalongo n’abantu abakulu abalina obulwadde obw’amaanyi obw’amawuggwe basobola okuwangaala. N’olwekyo, ggwe oba omwana wo bw’oba olina embeera eno, kikulu nnyo okwogera mu lwatu n’omusawo wo ku bujjanjabi bw’oyinza okukozesa n’ebiseera by’obulamu bwo eby’omu maaso.
Tukuuma tutya vvaalu eno nga nnungi?
Tetusobola kuziyiza bulwadde bwa mutima obuzaalibwa. Naye waliwo ebintu bingi bye tuyinza okukola okwekuuma ebizibu ebibaawo mu bulamu obw’oluvannyuma n’okukuuma emitima gyaffe nga miramu okutwalira awamu. Gezaako okuyingiza bino mu bulamu bwo.
- Weewale ddala okunywa sigala: Taaba ow’engeri zonna, so si sigala ne vapes zokka, mubi nnyo eri omutima. Bw’oba olina obuzibu okulekayo, saba omusawo akuyambe.
- Okunywa oba okukomya ennyo omwenge: Omwenge si mulungi eri obulamu bw’omutima.
- Lya emmere eyamba omutima: Kendeeza ku mmere erimu amafuta, omunnyo ne ssukaali omungi. Mu mmere yo ssaamu enva endiirwa, ebibala, ebinyeebwa n’emmere ey’empeke endala.
- Dduyiro buli kiseera: Nga omusawo bw’akulagidde, kola dduyiro ow’amaanyi ag’ekigero, gamba ng’okutambula, waakiri okumala eddakiika 150 buli wiiki.
- Okufuga endwadde nga puleesa ne kolesterol:Bw’oba olina endwadde ez’ekika kino, kozesa eddagala lino ddala nga bwe likulagidde omusawo.
- Okukeberebwa omusawo buli mwaka: Ne bw’oba tolina bulwadde bwonna, laba omusawo waakiri omulundi gumu mu mwaka akukebere obulamu bwo.
- Naddala ku bamaama abazaala: Bw’oba oli lubuto, genda mu malwaliro agatuukirawo ofune amagezi n’obujjanjabi obwetaagisa. Kino kiyinza okukendeeza ku bulabe bw’okufuna embeera ng’obulwadde bw’omutima obuzaalibwa.
Okuyiga ku nsengeka y’omutima n’engeri ebitundu byagwo gye bikolamu oluusi kiyinza okulabika ng’ekizibu katono. Naddala bw’okizuula nti ggwe oba omwana wo olina obulwadde bw’omutima. Kiyinza okuba ekizibu okuyingiza amawulire mangi omulundi gumu. Naye jjukira nti omusawo wo abeerawo bulijjo okukuyamba n’okuddamu ebibuuzo byo. Totya kubuuza kintu kyonna ekikuli mu birowoozo, ne bwe kiba kitono kitya.
Obubaka Obutwala Awaka
- Valiva y’amawuggwe vvaalu nkulu, egenda mu kkubo erimu esobozesa omusaayi ogutaliimu mukka gwa oxygen okugenda mu mawuggwe okulongoosa.
- Endwadde nnyingi ezikwatagana ne vvaalu eno ziyinza okuba ez’obuzaale. Weegendereze nnyo obubonero nga langi ya bbululu mu mwana eyaakazaalibwa.
- Bw’oba olina obubonero bwonna obw’obulwadde bw’omutima oba okubuteebereza, laba omusawo mu bwangu.
- Olw’enkola ez’omulembe ez’okulongoosa n’okujjanjaba ennaku zino, abantu bangi basobola bulungi okujjanjaba embeera zino ne babeera n’obulamu obulungi.
- Obulamu obulungi obw’omutima (endya ennungi, dduyiro, n’okwewala okunywa sigala) busobola okukuuma obulamu bw’omutima mu bbanga eggwanvu.
