Skeletal system
Hi ma'am
I learned in this lesson that there are 3 types of skeleton there are the hydroskeleton, exoskeleton, and the endoskeleton. The functions of the bones in our body are the following:

1. Provides support and protection.
2. Major reservoir for calcium and phosphorus.
3. Produces blood cells.
4. Provides an attachment for muscles.
I learned also that the smallest bone is the stirrup that found in our ear. The longest bone is found in our thigh the femur.
That's all ma'am thank you and God bless.
