Name: _ Section: __DL3 _____ Lab Report: Exercise 4: Overview of the Skeletal System Purpose: The Skeletal System serves many important functions; it provides the shape and form for our bodies in addition to supporting, protecting, allowing bodily movement, producing blood for the body, and storing minerals. In this lab I will be able to list the functions of the skeletal system, identify the four main kinds of bones, identify and give the functions of the microscopic structures found within bone tissue, and be able to identify and give the functions of the three major types of cartilage in the skeletal system. Activity 1: The Chemical Components of Bone 1. Describe the effect that the lemon juice (acid) had on the chicken leg bone. The bone is a structure formed of a collagen web composed of Calcium Carbonate. The lemon juice has Citric Acid, a weak acid. The reaction with the bone is slow but the acid slowly solves the bone. Making it flexible and with the loss of minerals a slightly transparent color. 2. Describe the effect that baking (heat) had on the chicken leg bone. The bone is hard and more brittle. It takes on a darker almost weathered look. I think this is due to a loss of collagen and alterations to the bone minerals. 3. Rickets is a disease where the bones are not formed completely in children due to a lack of vitamin D. Does the heated or the acid soaked bone represent a child with rickets? Explain why you think so. Yes it does.
