The pancreas-emepụtakwa ụfọdụ homonụ?

The pancreas na-ugbua ka enwere ìgwè abụọ: exocrine bi 98% na pancreatic cancer - n'ụdị obere inclusions n'elu ya ofụri elu.

Endocrine ngalaba maka secretion nke gastric ihe ọṅụṅụ ma na-achịkwa Filiks na-ewere ọnọdụ na duodenum na digestive ọmụmụ enzymes ede.

The endocrine akụkụ bụ maka hormone mmepụta.

mmiri ọgwụ ọrụ

The pancreas-arụpụta abụọ homonụ - insulin na glucagon bụ. The usoro nke na-eme ndị glucagon aka Alfa mkpụrụ ndụ, na insulin na-aka na mmepụta nke beta-mkpụrụ ndụ. Tụkwasị na nke a abụọ iche iche nke mkpụrụ ndụ ya nwere ihe ígwè na Delta mkpụrụ ndụ nke na-emepụta somatostatin.

Gịnị bụ homonụ emepụta anyịnya

mmadụ insulin kewara abụọ na ụdị: basal na kpaliri.

Basal ụdị e ji na na na-abanye n'ọbara enweghị mkpa. Otu ihe atụ nke ndị dị otú ahụ iche nwere ike ịbụ na mmepụta nke insulin, mgbe nri na-adịghị igba n'ime ahu, i.e. na ihe efu afo.

N'ihe banyere ebe pancreas-adịghị amị ọ bụla enzymes ugbu a, ma ọ bụ ọdịda emee fermentopathy jikọtara concomitant ọrịa.

The ọrụ nke homonụ

The ọrụ nke pancreas na mmepụta nke insulin na glucagon bụ ka ịhazie carbohydrate na lipid metabolism, nakwa dị ka mmetụta na redistribution nke glucose si ọbara plasma n'ime anụ ahụ.

Ya isi ọrụ bụ synthesize lipokaina nke na-agba ọrụ nke igbochi na mbelata nke imeju mkpụrụ ndụ.

Na ikpe nke a ụkọ mgbe pancreas arụpụta ezughi oke ọnụ ọgụgụ nke ndị dị otú ahụ ogige, mmiri ọgwụ ọdịda-amalite mgbe ọrụ usoro nke ihe organism, nke e mere n'ihi bụghị naanị enwetara, ma congenital malformations.

Mgbe pancreas arụpụta ezughi oke insulin hormone ego emee ọrịa - arịa ọrịa shuga. Na oké ngafe glucagon enwekwu insulin ọdịnaya na-ebelata ọbara sugar ịta nke mkpụrụ ndụ, nke n'aka nke na-enwekwu ego nke epinephrine. Mgbe ahụ, e hypoglycemia - a ọnụ ke ikike nke imeju mkpụrụ ndụ na nhazi nke glucose.

Enweghị ma ọ bụ oké ụkọ somatostatin na-eduga ná imebi nke dị iche iche na usoro nke organism ọrụ mebiri nke itule nke metabolic n'ibu.

Olee otú insulin

On ụdị homonụ emepụta anyịnya, wuru mmega abụba metabolism ofụri idem.

Tupu e guzobere insulin, mgbe ya nsụchi beta-mkpụrụ ndụ secrete a umi proinsulin. Site n'onwe ya na ọ bụghị a hormone.

Mgbe ahụ, e bụ re-absorption nke ya azụ, ebe ọ na granulated na zigara nchekwa, ebe ọ ga-Ewepụtara na ihe mberede mgbe n'ido ahụ n'ókè.

Nke a na usoro a na-triggered mgbe larịị nke sugar na ọbara mgbe mkpụrụ ndụ tọhapụrụ insulin echekwara maka ya neutralization na kwesịrị ekwesị nhazi glycogen, ịba ụba ya ịta na imeju mkpụrụ ndụ na muscle anụ ahụ, dị ka a soplaya nke ike maka dum. N'ihi mmetụta nke insulin, plasma glucose etoju nwere ike chụpụrụ ngwa ngwa ka mma.

Mgbe a mara kwa nke ya elu ọdịnaya na ọbara ya bụ na-ahuta ka a mgbaàmà na ahụ na-eguzogide merụsịrị ụba ntọhapụ nke hormone nke ejikọ na enweghị ike nke na-anabata ya maka carbohydrate metabolism, na-aghọta na iwepụ ihe ize ndụ a. N'ihi ya, ọ na-amalite ịzụlite a ọrịa ahụ a kpọrọ -arịa ọrịa shuga.

Gịnị na-ekpebi ntọhapụ nke insulin

The pancreas arụpụta enzymes na homonụ, ezi subtly mmetụta nwetụrụ mgbanwe ọbara sugar. N'ihi na nke a, na ọ na-anapụta n'ókè aka ahu na-amalite guzobe ụba ichekwa insulin, ma ọ bụ na ọ dị mkpa iji belata ya na-eziga ndị na idobere.

The pancreas arụpụta glucagon na Alfa mkpụrụ ndụ. Nsia mucosa interaglyukogon emepụta hormone, bụ nke na-a synergist adrenaline. Nke a pancreatic hormone maka eruba akara lipolysis na ya ike ọsọ, na-na-emetụta na hepatic glycogenolysis.

The isi dị oké mkpa ọrụ nke pancreas na ahụ mmadụ a nhọrọ nke dị iche iche homonụ na-akwalite mgbaze na absorption nke ya.
