Bhora nechisimbiso chechigaro chebhora zviri pedyo. Apo bhora rinosunungurwa, maziso emvura haana kuvharwa. Kana yakavharwa, denderedzwa rinovhara maziso ese emvura. Kudzvinyirirwa kwemukati annulus kunobata bhora, zvichiita kuti bhora uye chigaro chebhora munzvimbo yakakwirira yekuvhara.

3. Mashandisiro evhavha kelly
