Explanation:

• Question 61:
• Litho -: In medical and scientific terms, "litho -" is commonly used to refer to stone. For example, "lithotripsy" is a procedure to break up kidney stones.
• Petro -: It is also related to stone. In geology, "petrology" is the study of rocks (which are made of stones in a sense). In medical terms, "petrosal" (as in petrosal bone) has etymological roots related to the hard, stony nature of the bone.
• Lapio -: This prefix also means stone.
• Question 62:
• The word "alimentary" comes from the Latin word "alimentum" which means nourishment. The alimentary canal is related to the process of taking in food (nourishment), digesting it, and absorbing nutrients (nourishing the body).
• Question 63:
• A fistula is an abnormal passageway (like a pipe - stem like passageway) that connects two body cavities or a body cavity to the outside of the body. For example, an anal - cutaneous fistula is an abnormal connection between the anus and the skin around it.

• Question 61: Stone
