The ears are further from the middle of the body than the nose so the ears are

The ears are above the shoulders so in this case the ears are

The heart is in front of the spine so the heart is

The heart is closer to the middle of the body than the lungs so the heart is

The elbow is closer to the point of arm attachment to the trunk than the fingers so the elbow is

The elbow is further from the point of attachment to the trunk than the shoulder so the elbow is
