<em>The marrow in the bones of the skeletal system helps produce the cells in the blood, which is the key fluid of circulatory system</em>
<h3><u>Explanation;</u></h3>
- <em><u>Skeletal system is a system in the body that is made up of cartilage and calcified bone that work together by helping in the smooth movement process of the body. </u></em>
- <em><u>Circulatory system on the other hand is a system of the body that is made up of blood vessels that carry blood away and towards the heart. The system helps in transport of oxygen and nutrients in all the body tissues, and also transport of carbon dioxide and wastes out of the tissues.</u></em>
