Kubata pamuviri kunoreva nguva yepanyama mushure mekubata pamuviri usati wasununguka. Iri izwi rezvemuviri, rinozivikanwawo sekubata. Kazhinji zvinotora mazuva angangosvika makumi matanhatu nematanhatu kubva panguva iyo zai rakakura rinosangana kusvika pakuzvarwa kwechecheche. Nekureruka kwekuverenga, kubata kunowanzo kuverengerwa kubva pazuva rekutanga rekuenda kumwedzi kwekupedzisira, uye kuzara-kwenguva yepamuviri ingangoita mazuva mazana maviri nemakumi masere (vhiki makumi mana). Munguva yekuzvitakura, iyo yemadzimai metabolism, yekugaya system, mweya wekufema, vascular system, nervous system, endocrine system, yekubereka system, mapfupa, majoini, ligaments uye mazamu zvese zvinowirirana zvinoenderana.
Maitiro ese epamuviri akapatsanurwa kuita matatu nguva: isati yasvika vhiki yechi13 yepamuviri, inonzi nhumbu yekutanga; vhiki yegumi nemana kusvika makumi maviri nenhanhatu inonzi nhumbu yepakati-kati; uye vhiki ye28 uye zvichizotevera inonzi kunonoka kubata nhumbu.
