Magazi ndi kupuma dongosolo mu nyama. The matupi kupanga mitsempha ya magazi a nyama

M'nkhani ino tikambirana za mitsempha ya magazi a nyama, zigawo zake ndi mbali ya ntchito. Pakuti zamoyo zonse n'kofunika. Izi zolimbitsa mpweya kuwombola, zoyendera zakudya, mapangidwe chitetezo chokwanira ndi kukhalabe homeostasis. Chifukwa peculiarities mmene zotheka kugwira ntchito zovuta?

ndi amene nyama

Nyama ndi angapo zizindikiro zokhudza zonse. Choyamba, ndi calving mkaka, amene anamasulidwa ndi zopangitsa apadera akazi. nyama zonse ndi miyendo kuti anayikidwa pansi thupi, ndi tsitsi, nthawi kusintha pa molting. Mu nyama khungu lili osati mkaka, komanso thukuta, zopangitsa sebaceous ndi odorous. Nyama ndi magazi ofunda zamoyo yekha, amene amathandiza mbali ndi mitsempha ya magazi.

Kapangidwe ka m'thupi mwa nyama

Mbali zotsogola a dongosolo la m'thupi mwa inakhala ndi nthumwi ndicho Maphunziro nyama. Pamafunikanso mtima zinayi chambered, ndi dongosolo chatsekedwa Mitsempha. Ntchito yake wokhoza kuchita magazi chifukwa kayendedwe mosalekeza. Choncho matupi kupanga mitsempha ya magazi mu nyama, makamaka popangidwa ndi minofu minofu. Ndi mtima yotero.

Izi ndi dzenje akulu limba wopangidwa mwa zipinda zinayi: atria awiri ndi ventricles. Ndime izi anasiyanitsidwa ndi partitions ndipo malizitsani Zikuvumbulutsidwa mwa mavavu. Pachifukwa ichi, venous ndi wolumikizira magazi konse kusakaniza limodzi ndi njira ya bwino ya thermoregulation kumabweretsa magazi ofunda nyama.

ndi otentha bloodedness Kodi

Otchedwa magazi ofunda nyama zomwe sikudalira kutentha kwa thupi ku chilengedwe. Kwa gulu ili a mbalame ndi nyama, kuphatikizapo munthu. N'chifukwa chiyani nyama zina mulibe deta ya chizindikiro mwapang'onopang'ono? nkhani zonse mu dongosolo la mtima. Taganizirani funso ili amayerekezera oimira mayunitsi osiyana mwadongosolo. Choncho, mitsempha ya magazi a nyama ndi zokwawa ali kusiyana kwambiri. Mtima yamasika imakhala ya zipinda zitatu, pakati muli ndi kugawa chosakwanira. Izo pang'ono okha kumathandiza kusanganikirana magazi venous ndi wolumikizira. Choncho, zokwawa zonse - mwankhanzaku ndi nkhawa nthawi yozizira pansi pa matupi a madzi, nthaka ndi makola ena.

awiri kufalitsidwa

Zolengedwa zoyamwitsa mitsempha ya magazi ndi kupanga nsupa. Malinga ndi iye kayendedwe ka magazi kumachitika. Mu mtima ndi mtsempha wamagazi, yaikulu ya chimene chimatchedwa msempha. Kenako nthambi kuchoka muyende mu capillaries lapansi. Awa ndi ziwiya yaing'ono. Capillary maukonde Akusonkhanitsa venules. Iwo pang'onopang'ono kuonjezera awiri. Popeza kupanga mitsempha kuti kunyamula magazi mtima.

Mitsempha ya magazi a nyama, njira ziwiri kufalitsidwa. Chabe likadutsa m'mapapo. Umayamba mu ventricle bwino ndipo amanyamula magazi kudzera mitsempha, capillaries ndi mitsempha ya thupi kwa atrium kumanzere. Chifukwa, mpweya wa mpweya umene uli mu mapapo, magazi umalowa ndi mpweya - zosiyana. Zokhudza zonse makope akuyamba mu ventricle kumanzere ndipo popitapita zotengera za ziwalo zonse za thupi, amanyamula magazi kwa atrium bwino.

magazi zikuchokera

Mitsempha ya magazi a nyama sanathe kuchita ntchito zake popanda madzi minofu wapadera kuti amazungulira mu dongosolo mtima. Njirayi imatchedwa magazi. Chifukwa cha nsalu iyi ndi intercellular mankhwala - madzi a m'magazi. Pali mitundu itatu ya zinthu anapanga, omwe amagwira ntchito yake. The kusintha madzi kuchokera zimakhala ziwalo zimatulutsa mankhwala mapeto kagayidwe kachakudya, madzi owonjezera ndi mchere. Kuyambira pamaziko a magazi ndi madzi kukhala mkulu kutentha mphamvu, izo kupitiriza khola thupi kutentha kwa nyama.

Erythrocytes kuwombola mpweya ikuchitika ndi kayendetsedwe ka mpweya ndi mpweya. Maselo amenewa kuyambitsa mtundu ofiira a magazi, chifukwa iwo ali chitsulo. Leukocytes anapanga zinthu chitetezo chokwanira. Iwo m'mimba particles intracellularly achilendo ndi phagocytosis. Othandiza kupereka ndondomeko clotting magazi. Lamavutoli mankhwala Njira yozindikira mapuloteni insolubilization. Kudzera mu thupi ili zimatetezedwa ku imfa ya magazi. Koma ntchito zonsezi n'kofunika zimatheka pamene okwana ntchito ziwiya maselo amenewa, mtima ndi magazi.

Features a dongosolo kupuma

Magazi dongosolo la nyama ndi anatomically ndi zimagwirira ntchito kugwirizana ndi kupuma. yotsirizira akuyimiridwa mu nyama njira pneumatic ndi mapapo. Woyamba imakhala nkhani ndi chikugwirizana M'mimbamo m'mphuno, nasopharynx, kholingo trachea ndi bronchi awiri. Iwo anaphimba ndi kuunika, amene ali ambiri thovu chabwino - ndi alveoli, kuluka ndi maukonde wandiweyani ziwiya capillary. Ilo liri mu alveoli mpweya kuwombola amapezeka. Kupuma nyama - ndondomeko zovuta. Mu kukhazikitsa ikukhudza minofu intercostal, khoma m'mimba ndi zakulera.

Ubale wa kachitidwe magazi ndi kupuma nyama

Magazi ndi kupuma dongosolo la nyama ndi zogwirizana kwambiri. Pamene wina akapuma mpweya akulowa airway kwa alveoli a m'mapapo. Choncho, likulowerera mu capillaries lapansi. Wotuluka mu magazi, mpweya amamangiriridwa erythrocytes. Maselo amenewa muli mtima m'malo chinthu wakupambulika dzinache hemoglobin. Amakhala ndi mapuloteni ndi mankhwala chitsulo munali - heme. Izi amafotokozera mankhwala imapanga pawiri wosakhazikika ndi oxygen. Ndi m'magazi maselo ofiira kulinyamula thupi lonse. Kumvera Mpweya wabwino iwo amagwira, amene kachiwiri akulowa mapapo. Pa mpweya, metabolite izi atachotsedwa thupi.

Choncho, mitsempha ya magazi a nyama ndipamene ziwiya mtima ndi magazi. Iwo ali choyimira chatsekedwa. MwaukadauloZida mbali ya kapangidwe dongosolo ndi kukhalapo kwa zipinda mtima anayi ndi kugawa wathunthu pakati pawo. Zimenezi zimabweretsa nyama magazi ofunda. Ndi magazi anatomically ndi zimagwirira ntchito zogwirizana dongosolo kupuma. Amakhala Airways ndi mapapo. Kokha kupyolera kanthu yatsopano kachitidwe anagwira nyama mpweya pa milingo ma minofu, ndi chamoyo.
