So woasusuw sɛnea mogya fa wo nipadua nyinaa mu ne sɛnea ɛma mogya mmoroso kɔ so tra hɔ daa no ho pɛn? Yɛwɔ mogya ntini bi wɔ yɛn nipadua mu a ɛyɛ ketewaa araa ma ɛkame ayɛ sɛ aniwa ntumi nhu, nanso ɛwɔ tumi kɛse. Ɛnnɛ yɛreka saa abran nkumaa yi ho asɛm, Arterioles.
Sɛ yɛbɛka no tiawa a, dɛn ne saa ntini ahorow yi?
Arterioles yɛ mogya ntini nketenkete paa na ɛyɛ tratraa. Wɔte sɛ nkorabata a efi mogya ntini atitiriw a ɛwɔ yɛn nipadua mu, ntini ahorow no mu fi nkorabata mu. Fa no sɛ akwan nketewa a ɛwɔ nkyɛnkyɛn a efi ɔkwan kɛse bi so fi nkorabata so na ɛkɔ afie mu. Saa ntini ahorow yi ne nea ɛde mogya fi koma no mu kɔ yɛn nipadua no ntini ne akwaa ahorow mu.
Saa ntini nketenkete yi ne mogya ntini nketenkete di nkitaho. Yɛfrɛ wɔn capillaries. Ntini mu ntini yɛ mogya ntini a ɛyɛ tratraa yiye, te sɛ akɔre ntaban nhama. Ɛha na nneɛma a ɛho hia sen biara no si. Wɔte sɛ beae a wɔsesa nneɛma. Mogya no ma mframa pa ne aduannuru ma ntini ahorow no, na ntini no de nneɛma fĩ te sɛ carbon dioxide san kɔ mogya no mu. Wɔ saa nsakrae yi akyi no, ntini nketenkete (venules) bata saa ntini nketenkete yi ho ma ɛde mogya a nwura ayɛ no ma no san kɔ koma no mu.
Enti, ntini ahorow yɛ abusuabɔ a ɛho hia yiye a ɛda ntini ne ntini nketenkete ntam.
Dɛn ne dwumadi titiriw a saa ntini nketenkete yi yɛ?
Ɛwom sɛ eyinom sua de, nanso edi dwuma titiriw wɔ mogya a ɛsen ne mogya mmoroso a ɛwɔ yɛn nipadua mu no mu.
- Mogya mmoroso ne mogya a ɛkɔ yɛn nipadua mu no sohwɛ: mogya a ɛko tia mogya a ɛkɔ yɛn nipadua mu no mu 80% na saa ntini ahorow yi na ɛhwɛ so. Sɛ yɛbɛka no tiawa a, mogya ntini nketewa yi na ɛkyerɛ sɛnea wɔde mogya kɔ akwaa biara mu ntɛmntɛm, sɛnea ɛyɛ den, ne dodow a wɔde kɔ akwaa biara mu. Wɔnam ntini a ɛwɔ wɔn afasu mu a wɔtwetwe na wɔma ɛyɛ mmerɛw no so na ɛyɛ eyi. Ɛte sɛ nea worepiapia nsu paipu de ahyɛ nsu a ɛsen no so. Eyi ne ɔkwan a wɔfa so ma yɛn mogya mmoroso kɔ so yɛ nea ɛyɛ den.
- Boa a wɔboa ma wɔsesa: Sɛnea yɛadi kan aka no, ntini ahorow no yɛ adwuma sɛ "mfinimfinifo" wɔ ntini akɛse ne ntini nketewa no ntam, na ɛyɛ adwuma sɛ ɔkwan a wɔfa so sesa oxygen, aduannuru, ne nneɛma a wɔsɛe no.
