Igazi elisuka ngakwikhohlo lentliziyo lizele yi-oksijin ne-zakha-mzimba. Izakha-mzimba zizinto ezifunwa ngumzimba wakho ukuze ube nokuphila, izinto ezinje ngee-proteni, amafutha, iikhabhorhidrate, ivithamini, kunye nee-minerali zokutya. Apha phantsi kwale systematic circulation ke kulapho igazi lizisa khona i-oksijin nezakha-mzimba emzimbeni wakho.

Le mibuliswana ibubuvuvu ingoo-Royinani! noo-Royindara! Molweni!. Ibifanelwe ukulahlwa kuba yeyasemzini, yaye ingenanto iyithethayo kuthi bamnyama. Akunani nani ukuthi, - ""Yitshoni.

Ubomi bomthi buqinisekiswa zizazinge ezibonakalisa ukukhula kwawo. Oku kungabonakala xa umthi ugawuliwe okanye kummongo othathwe ukusuka ekupheleni komthi ukuya esizikithini sawo. Uqikelelo olululo lungakho kuphela kwimithi ekwenze kuyo izazinge zokhulula kwawo, singathi nje ezo zenzeka ngokwemo yezulu ngokwamaxesha onyaka. Imithi esoloko ikhula kwimozulu engatshintshiyo efana neyaseTropika isoloko ikhula kwaye ayinazazinge zibonakalayo zokukhula. Kungenzeka kuphela kwimithi eqinileyo kwisizikithi kwisizikithi semithi; imithi emidala emininzi ihlala ingamaholo njengokhuni olufileyo kodwa lube lungaboli. Inxalenye yezi ntlobo, uqikelelo lobudala luye lwenziwa kujongwe isantya sokukhula komthi esikhoyo. Kodwa iziphumo zisoloko zingconwana kunamaqashiso okanye kunokwenza ngokuqina kwentloko. U-White ucebisa ngendlela ekungaqikelelwa ngayo ubudala bemithi emide nemidala eUnited Kingdom ngokuthi kuqhathaniswe ubukhulu besiqu somthi kunye, nesimbo okhula ngaso umthi kunye nobudala.

Igazi lithwalwa ngemibhobho ehamba igazi. Le mibhobho ke ngoonothumela noonobuyisa. Igazi eliya entliziyweni lihamba ngoonobuyisa. Igazi elishiya intliziyo lihamba ngoonobuyisa. Oyena nothumela mkhulu ophuma kwintliziyo nge-ventricle yangasekunene ngunothumela oyi-pulmonary. (I-Pulmonary ithetha ngokumalunga nemiphunga.) Oyena nothumela mkhulu ophuma nge-ventricle yangasekhohlo yi-aorta.

Zininzi iindlela zokuchaza ubunjani bomntu onokuxhaphaza abantwana bethu ngokwesondo. Awona magama axhaphakileyo babizwa ngawo ngala: izidlwengu okanye abaxhaphazi beentsana ngokwesondo. Eyona nto ibalulekileyo kukwazi ukuba umntu omdala okanye umntu omtsha osele ebuqina xa ethe waphula umthetho ngokuxhaphaza umntwana ngokwesondo, akukwazeki ukuba banganyangeka kweso simo. Nangona zikho iinkqubo zokuzama ukunyanga la marhamncwa, uninzi lwazo aijolise ekususeni ixhoba [umntwana wakho] kulo mphembeleli [isidlwengu]. Niengenxila ntywaleni, xa la marhamncwa ekwiindawo ezinabantwana bethu, aye angakwazi ukuzibamba kumnqweno wokuxhaphaza nokudlwengula abantwana bethu izihlandlo ngezihlandlo. Ubukhulu becala, izidlwengu nabaxhaphazi babantwana bayaziwa ngabantwana naziintsapho.

Kwi-periodic table, singazoba umgca we-zigzag osuka kwi-element eyi-boron (uphawu lwayo ngu-B) ukuya kwi-element eyi-polonium (uphawu lwayo ngu-Po). Ii-elements ekunqumla kuzo lo mgca zii-metalloids. Ii-elements ezihamba ngaphezulu nangasekunene kwalo mgca zii- nonmetals. Zonke ke ezinye ezi ii-elements zizii-metals.
