Te Hanganga me te Mahi a ngā Okana o te Pūnaha Whakaputa Uri
He kohinga okana te pūnaha whakaputa uri o te tangata e mahi tahi ana mō te kaupapa o te whānautanga. I roto i ngā tāne me ngā wāhine, he hanganga me ngā mahi ahurei engari he hononga tahi ngā hanganga me ngā mahi o te pūnaha whakaputa uri. I roto i tēnei tuhinga, ka matapakihia e mātou te hanganga me te mahi o ngā okana whakaputa uri o ngā ira e rua.
Pūnaha Whakaputa Uri Tāne
Ko te pūnaha whakaputa uri tāne e arotahi ana ki te whakaputa, te pakeketanga, me te tuku i te parāoa ki te pūnaha whakaputa uri wahine. Anei tētahi tirohanga ki te whanaketanga o ia okana me tana mahi:
1. Ngā rauropi
Ko ngā porotiti ngā okana matua o te pūnaha whakaputa uri tāne, kei roto i te kiriuhi. Ko tā rātou mahi matua he whakaputa parāoa me te homoni testosterone. Ka whakaputaina ngā parāoa mā te tukanga e mōhiotia ana ko te spermatogenesis, e puta ana i roto i ngā ngongo seminiferous.
2. Ngā puku o te epididymis
He ngongo kopikopiko te epididymis e piri ana ki te tuara o ia teke. Ko tana mahi he penapena me te whakatupu i te parāoa. Kāore anō kia taea e te parāoa e wehe atu ana i ngā teke te nekeneke kaha, ā, me maha ngā wiki kia pakari ai i roto i te epididymis.
3. Vas Deferens
He ngongo te vas deferens e hono ana i te epididymis ki te awa whakaputa uri. Ko tana mahi matua he kawe i te parāoa mai i te epididymis ki te urethra i te wā e whakaputa uri ana.
4. Ngā Pūwero Whakatō
Ko ngā pūwero purapura he takirua repe e whakaputa ana i te wai e nui ana te fructose me ētahi atu matū hei whāngai me te whakahaere i te nekehanga o te parāoa. Ko tēnei wai te nuinga o te rahinga o te parāoa purapura.
5. Repe Pūtau
Kei raro i te pūkahukahu te repeure, ā, e karapoti ana i te wāhanga o runga o te urethra. Ka whakaputa te repeure i tētahi wai kawakore e whakakore ana i te waikawa i roto i te urethra me te tara, e whakarato ana i tētahi taiao pai ake mō te parāoa.
6. Ngā repe Bulbourethral (Cowper)

Pūnaha Whakaputa Uri Wahine
Kua hangaia te pūnaha whakaputa uri wahine hei whakaputa hua manu, hei whiwhi parāoa, hei whakarato i tētahi wāhi mō te whakatōnga, me te tautoko i te whanaketanga o te kukune. Anei tētahi kōrero mō te hanganga me te mahi a ngā whekau whakaputa uri wahine:
1. Ngā Ōwai
He takirua repe iti ngā ovaries kei roto i te kōhao pelvis. Ko te mahi matua a ngā ovaries he whakaputa hua manu (ova) me ngā homoni estrogen me te progesterone. Ia marama, ka tukuna e te ovaries kotahi he hua manu i roto i te tukanga e kiia nei ko te ovulation.
2. Ngā ngongo whēkau
Ko ngā ngongo fallopian ngā ngongo e hono ana i ngā ovaries ki te kōpū. I muri i te whakaputanga o te hua manu, ka hopukina te hua manu e ngā hanganga rite ki te matihao i te pito o te ngongo fallopian. Ko te whakatōnga a te parāoa i roto i tēnei ngongo te tikanga ka puta.
3. Kōpū (Uterus)
He okana uaua te kōpū, he āhua pea, kei roto i te hope. Koia te wāhi e whakatōngia ai te hua manu kua whakatōkia, e tautoko ana i te whanaketanga o te kukune i te wā e hapu ana, ā, e whakawhāiti ana i te wā e whānau ana.
4. Endometrium
Ko te endometrium te arai o roto o te kōpū e whakarārangi ana i te kōpū, ā, e piri ana ki te kukune i muri i te whakatōnga. I ia huringa paheketanga, ka matotoru tēnei arai hei whakarite mō te whakatōnga, ā, ka marere mena kāore e hapu.
5. Te kōpū o te kōpū
Ko te kaki o te kōpū te wāhanga o te kōpū e puta atu ana ki roto i te tara. He mahi nui tāna ki te whakahaere i te rere o te paheketanga mai i te kōpū ki te tara, ā, ka tuwhera i te wā e whānau ana kia whānau ai te pēpi.
6. Te tara
He awaawa te tara e hono ana i te kaki o te kōpū ki waho o te tinana. He awaawa whānau tēnei i te wā e whānau ana, he putanga mō te paheketanga, me te wāhi e tomo ai te ure i te wā moe tāne.
Ngā Mahi me ngā Hononga o te Pūnaha Whakaputa Uri
Kāore te pūnaha whakaputa uri e mahi motuhake. I te wā o te pakeketanga, ka whakahaere ngā homoni e hangaia ana e ngā repe endocrine i te pakeketanga tinana me te rite o te whakaputa uri. I roto i ngā tāne, ka whakahaere te testosterone i te whakaputanga parāoa me te whanaketanga o ngā āhuatanga ira tangata tuarua pērā i te hohonutanga o te reo me te tipu o te huruhuru kanohi.

Ko te angitu o te whakaputa uri o te tangata e whakawhirinaki ana ki te mahi tahi me te whakaurunga o ia wāhanga o te pūnaha whakaputa uri, me ngā awe o ngā homoni e whakatau ana i te wā me te rite mō te whakaputa uri.
Whakamutunga
Kua hangaia ngā pūnaha whakaputa uri tāne me te wahine hei whakarite i te haere tonu o te oranga tangata mā roto i ngā mahi me ngā hanganga tautoko. Ahakoa he motuhake ngā okana me ngā mahi a ia okana, ka mahi tahi rāua i roto i te tukanga whakaputa uri. Ko te mārama ki te hanganga me te mahi a ngā okana whakaputa uri te taahiraa tuatahi ki te mōhio nui ake ki te hauora whakaputa uri me te hiranga o te tiaki hauora tika mō te mahi pai o ēnei pūnaha puta noa i te oranga o te tangata.
