Ka 'ole o ka naau

O i ike ole ia i ka naau - i ka papa kuhikuhiE hui, i loko o ke kanaka kino. ʻOiai ua mea na kanaka, i ka ha awina o ka naau ua hōʻike like ma luna o kona kūloko ma moku'āina, a mawaho palapala. Heart - noke ke hoʻohana hiki wawe ko engine, a EII ni ka ipu weliweli nui o ke koko. Single-kapakahi pele o ke koko ua lako pono naau kiwikā, a i weheia ma lalo o puʻe i loko o kekahi ao ao. Ka naau Muscle aelike pololei a me ka maopopo, e manao ana incredibly nui overload. A pau o kona ola ka kanaka naau hana noke, a ma ka mea kākoʻo i kēia ola.

A eia i hoounauna papa a me ka e ka naʻau hana ikaika, a me ka no o ka naau Muscle ua hoopaaia. Eia naʻe, e like me ka 'auhau ua mahuahua ventricles. Inā ka naau Muscle mea luhi mai ka hana a me ka hiki ole i loaa i ka pau koko komo i ka lua e hoʻomōhala congestive naʻau hoʻonui a me ka naʻau 'ole. E aho maopopo mau keʻano o ka hanaʻana, he mea pono e delve i loko o ia i kekahi mea e like me "me ka 'ole o ka naau."

Ka mawaho 'ole o ka naau

I hookuu, ka wā i ka hua'ōlelo "naau" kanaka imagines he uuku ulaula naʻau houia e ka pua Cupid. Eia naʻe, ina ua ike, ia mea maoli i ka hihia? O ka holo ana mai.

Heart kinona -ʻohana, flattened ma ka anteroposterior ao ao. Ka 'ole o ka naʻau hoʻohuʻu ke hoʻokaʻawale i waena o ka waihona ipu, a me ka luna. Base -, ua kīkoʻo akula kekahi i olelo ai i ka akau, i, a kānaka hoʻi, luna - haʻahaʻa tapered hapa, niioaaonoaaiii, kuhikuhi i ka hema, i lalo a me iki aku.

Ma ka ili o keia kino, ua hiki ke huai ae he nui kekahi mau protrusions a me Groove i kuahene ipu koko. I ka nui o lakou i ko lakou mau inoa. Kēia, no ka laʻana, coronal sulcus, i kŰlń ao transversely i ka iho (axis) o ka naau a me ka mawaho delimitation laʻau kuhikuhi ventricles a me atria. Eia hou, i ka ili honua o ka naau i ka hope a me ka mua interventricular Groove - mawaho hoailona o ka ventricular mokuna. Eia no hoi e moe i ka ipu naau. I nā mea a pau, he mea mau ka ulu o ke ana ma ka ili o ka naau - ka atria pepeiao.

Na na 'ole o ka naau

Loko o ka naʻau ia mea oi pilikia. Ka mua meaʻoe e hoʻolohe i këia i ka 'ole o ka naau, o ka mea i loaʻa i eha kiwikā, kaulike i ka neʻeʻana o ke koko i loko o ka mua, kuhikuhi, a ua ālai' kona hoʻiʻikena. Tricuspid a mitral atrioventricular kiwikā hookaawale i ka ventricles mai ka atria, pulmonary a me aortic semilunar kiwikā - ventricles o na arteries nui. A pau o ia e pili ana i ka fibrous iwi o ka naau. Heart haka ai ninoieo o ka manoanoa loa, connective'aʻaʻa, i mea he kākoʻo i nā nāʻiʻo a me ka nohona kiwikā.

I mau, hōʻike no ka 'ole o ka naʻau, e mea pono e hoailona oukou i ka mea naʻau ninoieo o ka eha keʻena: no ka haʻalele atrium, pono atrium, hema ventricle a me ka pololei ventricle. A pau o ia i kaawale ma i pohā. Ka haʻalele atrium kikowaena pulmonary aa koko i loko o ka lima'ākau - puha. Mai ka hema a me ka pono ventricles i ke aupuni 'pulmonary artery, a pii aku aorta, niioaaonoaaiii. Ka akau atrium a me ka ventricle hema pani i ka nui holo, ka haʻalele atrium a me ka ventricle'ākau - he uuku hoa kanaka.

Ka loko ili o ka naau keʻena a me ka nohona kiwikā i hoalaala ia me ka ahu iho la ka ai-kapaia endothelial keena - endocardium. Ma subendocardial'aʻaʻa hoopii fibroblasts, collagen a me ka laholio olona, nä olonä, aa koko, ka lawelawe oihana mua o ke kahua. Dala i loaa mai i kēia myocardial'aʻaʻa - ka Muscle anuanu, ahu iho haku o cardiac Muscle keena. E noke i ka waho o ka myocardium ia lŘlŘ, ahu iho momona a me ka connective'aʻaʻa, a uhi i nā aʻalolo e hele ana i ka Muscle, ahu iho o ka naau, me ka naau a me ka nui o na moku.

'ole o ka naau - he mea hana hoihoi a me ka mea nui loa i loko o kanaka'anatomia. Wale poko ia a hiki i ka hopena o na nuances a pau o kēia pukana, e hiki maopopo mea ka o ko makou kino, a pehea e kākoʻo kanaka ola.
