Mtima dongosolo - mmodzi wa kachitidwe lalikulu thupi

Normal, zogwirizana kugwira ntchito kwa thupi N'zosatheka zonse kunachitika kuonetsetsa lililonse maselo ake ndi mpweya ndi zakudya. Chinanso chofunika kwambiri ndi lathunthu yake achire wa zatsalira zinthu ntchito. gawo la mikango mwa ntchitozo zimatengera pa dongosolo mtima. Choncho, malingana ukupeza cha thupi lathu.

matenda osiyanasiyana ndi matenda mu dongosolo mtima, zomwe ndi zochokera atherosclerosis, tsopano limodzi mwa mavuto aakulu kwambiri a mankhwala amakono. Pa dzanja limodzi, thupi, ndi izo, ndi kachitidwe mtima nthawi zonse kuona m'maganizo ndi m'thupi nkhawa - malo oipa, nkhawa, zakudya osauka, etc. Ndi pa zina - zonse ife kudya zakudya ali magwero a zakudya ndi kukonzedwa m'njira osiyanasiyana kutaya kwambiri zinthu zofunika. Motero pali akusowa zakudya, ndipo pamodzi nacho "kuchepekedwa" thanzi.

Human mtima System - mmodzi wa kachitidwe lofunika kwambiri la chamoyo, izo akapatsidwa kugwira ntchito monga zoyendera zakudya, mahomoni, mpweya, ndi mankhwala kagayidwe kachakudya ku maselo thereto, chitetezo ku maselo ena ndi kuwukira tizilombo, lamulo la thupi kutentha. ntchito zonsezi anachita mwachindunji ndi lymph ndi magazi. Magazi ndi madzi connective minofu, kufalitsidwa dongosolo Mitsempha ndi lymph - madzi, madzi bwino munali woyera maselo a mwazi ndi ili mu lymphatics.

Kodi ndi dongosolo mtima?

The Gawo la dongosolo mtima ndi mitsempha ya magazi (mitsempha, mitsempha ndi capillaries) amene angatithandize ziwalo zonse ndi kachitidwe, ndi mtima, ndi dongosolo lofunika kwambiri kwa thupi. Kanthu momwe "wathanzi" kapena "ayi wathanzi" Mitsempha wako umadalira ntchito ya chamoyo wonse. pafupifupi mtima Kunenepa ndi magalamu 300, ndi kukula - ndi clenched nkhonya. The mtima akhoza kuchotsa malita 5 magazi pa mphindi pa mpumulo ndi 25-35 malita / min. akhoza kusonyeza.

Ntchito yaikulu ya mtima ndi kayendedwe rhythmic magazi kudzera ziwiya; tichipeza ventricles awiri kuchita mpope ntchito ndi atria awiri, mu magazi anasonkhana. The atrium bwino amasonkhana pa lonse magazi m'thupi venous, ndi lamanzere - wolumikizira magazi m'mapapo. Makoma a mtima tichipeza zigawo zitatu: ndi pericardium, myocardium ndi endocardium. The otsogolera mu ntchito mtima wa chapakati wosanjikiza - wa myocardium, amene amathandiza mabala ake umuna magazi kunja mtima.

dongosolo mtima aumbike mwa awiri makope mabwalo: yaikuluikulu. achokera Big mu ventricle kumanzere ndi malekezero mu atrium lamanja, magazi akukamba ziwalo zonse ndipo zimakhala za thupi. Amayendera m'mapapo womangika magazi aziyenda bwino mu phapo, amene Polemeretsedwa mpweya kuchokera ventricle bwino limayamba komanso limatha ndi atrium kumanzere.

Mtima - m'dzenje, rhythmic ndi ntchito bwino, kupereka thupi ndi magazi ndi mpweya moyo, akulu thupi. Aliyense kusintha pathological ziwiya magazi zikuphatikizapo kuphwanya pamodzi ziwalo ndi kachitidwe, ndi chitukuko cha matenda osiyanasiyana, monga mwachitsanzo monga kulephera mtima. makhalidwe Aika ndi: kufooka, edema, dyspnea, palpitations. Zizindikiro, nthawi zambiri, amaoneka pang'onopang'ono monga matenda akufotokozera pang'onopang'ono, kotero ndikofunika kudziwa nthawi yomweyo.
