→Respiration is the movement of oxygen from the outside environment to the cells within tissues, and the removal of carbon dioxide in the opposite direction.

$\bf \underline \purple{3. \:what \: is \: cryosurgery?}$

→Cryosurgery is the use of extreme cold in surgery to destroy abnormal or diseased tissue; thus, it is the surgical application of cryoablation. The term comes from the Greek words cryo and surgery meaning "hand work" or "handiwork".
