Litšobotsi tsa bajari ba phelelang
1. Tsamaiso ea bokhachane
Diphologolo tse di sa tsheleng di farologane le tsa diphologolo tse di golang tse di beelang mae a "kwa ntle", jaaka bontsi jwa dinonyane le digagabi. Liphoofolo tse mafolofolo li na le sistimi ea kemolo e tsoetseng pele le ho ntlafatsoa ho feta liphoofolo tse nang le mahe a linotši, tse bitsoang placental viviparism, ke hore, liphoofolo tseo lesea la tsona le emolisitsoeng ba fumaneng mangolo ka mokotleng "placenta" kahare ho mme ho fihlela mme a holile, a le moholo ebile a le matla hoo a ka tsoaloang le ho phela ka bohona kantle ho 'mele.
2. Placenta
