Explain two ways the cardiovascular and skeletal systems are interdependent?

1. Calcium regulation: The skeletal system acts as a reservoir for calcium, the most abundant mineral in the body. The cardiovascular system helps regulate calcium levels in the blood by transporting calcium ions from the bones to other parts of the body, such as the muscles and nerves. This process is essential for muscle contraction, nerve transmission, and bone health.

2. Blood cell production: The skeletal system produces red blood cells (RBCs) in the bone marrow. RBCs carry oxygen throughout the body. The cardiovascular system transports RBCs to different tissues and organs, delivering oxygen and removing waste products like carbon dioxide. Without the cardiovascular system, RBCs would not be able to reach the tissues that need them, and the body would not be able to function properly.
