SCIENCE

• The bone marrow within bones is responsible for producing red blood cells, white blood cells, and platelets.
• Bones in the skeletal system store essential minerals such as calcium and phosphorus, releasing them into the bloodstream when needed.
• The skeletal system provides structural support for the body, protecting internal organs and allowing movement through its joints.
• Red blood cells carry oxygen throughout the body.
• The skull protects the brain from injury.
• There are two types of joints - synovial (freely movable) and fibrous (immobile).
• White blood cells fight infection and disease.
• The ribcage protects vital organs like the heart and lungs.
• Synovial joints allow for free movement between bones and contain cartilage to cushion against friction during movement.
• Platelets are involved in clotting to stop bleeding.
• Long bones are found in the arms and legs and allow movement through joints.
• Platelets form clots to stop bleeding.
• Fibrous joints do not have any space between bones and are immovable.
• Synovial joints allow for free movement between bones.
• Bones can be classified as long bones or short bones based on their shape.
• Fibrous joints connect bones together without any space or movement.
• Calcium helps with muscle contraction, nerve function, and maintaining healthy teeth and bones.
• Fibrous joints, such as sutures in the skull, do not move at all.
• Blood is made up of plasma, red blood cells, white blood cells, platelets, and other substances like proteins and hormones.
• Fibrous joints connect bones together without allowing any movement, providing stability and support.
• Cartilage covers the ends of bones at synovial joints to prevent friction during movement.
• Blood is transported to different parts of the body by arteries, veins, and capillaries.
• Short bones have equal length, width, and thickness and are found in the wrists and ankles.
• The circulatory system transports nutrients, waste products, gases, and hormones throughout the body.
• Short bones have equal length, width, and thickness and can be found in the wrists and ankles.
• Platelets form clots to stop bleeding when there is an injury or cut.
• Cartilaginous joints have some flexibility but limited range of motion.
• Long bones have a shaft with an epiphysis at both ends.
• Bones provide structure and support for the body.
• The skeleton is made up of different types of bone tissue, including compact bone (dense), spongy bone (cancellous), and cartilage.
• Flat bones are thin and flat, such as those that make up the skull or rib cage.
• Cartilaginous joints have some flexibility but limited range of motion due to the presence of cartilage.
• Phosphorus is important for bone health and energy production.
• Cartilaginous joints join two bones with cartilage, allowing some limited movement.
