Which bone tissue is found more on the inside (interior) of bone and very poreous (lots of holes)? smooth compact calcitonin spongy

## Step 1<br />The question is asking about the type of bone tissue that is found more on the inside (interior) of the bone and is very porous (lots of holes). <br /><br />## Step 2<br />The options provided are smooth, compact, calcitonin, and spongy. <br /><br />## Step 3<br />Smooth and compact are types of bone tissue, but they are not characterized by being porous or having lots of holes. <br /><br />## Step 4<br />Calcitonin is a hormone that helps regulate calcium levels in the blood, not a type of bone tissue. <br /><br />## Step 5<br />Spongy bone, also known as cancellous bone, is found at the ends of long bones and in the interior of other bones. It is characterized by a porous, honeycomb-like structure, which makes it lighter and less dense than compact bone.
