Detailed explanation-1: -The Cardiovascular system and the skeletal system interrelates with each other, which plays a vital role in keeping the human body alive. The bone marrow within your bones form new red and white blood cells and removes dirty blood cells. After making these new blood cells, it sends them to the circulatory system.
Detailed explanation-2: -The skeleton helps in movement and also provides protection to internal organs. The rib cage is a part of our skeleton which protects heart and lungs.
Detailed explanation-3: -The ribs are connected to the sternum with a strong, somewhat flexible material called cartilage. The rib cage help protects the organs in the chest, such as the heart and lungs, from damage.
Detailed explanation-4: -Bone receives up to about 10% of cardiac output, and this blood supply permits a much higher degree of cellularity, remodelling and repair than is possible in cartilage, which is avascular.
