The tissue that protects organs in body cavities provides attachment for muscles, forms blood cells, and stores inorganic chemicals such as calcium and phosphorus is .

The tissue that you're referring to is Bone tissue. Bone tissue, also known as osseous tissue, is a type of connective tissue that performs several functions including:

1. Protection: It protects vital organs. For example, the skull protects the brain, the rib cage protects the heart and lungs.

2. Attachment for muscles: Bones provide a surface for the attachment of muscles. The contraction and relaxation of these muscles leads to movement.

3. Formation of blood cells: The process of blood cell formation, known as hematopoiesis, occurs in the red marrow found within certain bones.

4. Storage of inorganic chemicals: Bones act as a reservoir for minerals, the most important of which are calcium and phosphorus. These minerals are released into the body as needed.

The tissue that protects organs in body cavities, provides attachment for muscles, forms blood cells, and stores inorganic chemicals such as calcium and phosphorus is bone tissue.

1. Protects organs in body cavities: Bone tissue forms structures like the skull, rib cage, and vertebrae, which protect vital organs such as the brain, heart, and lungs.
2. Provides attachment for muscles: Bones serve as attachment points for muscles, enabling movement through the leverage provided by the skeletal system.
3. Forms blood cells: Bone marrow, found within certain bones, is responsible for the production of blood cells, including red blood cells, white blood cells, and platelets.
4. Stores inorganic chemicals: Bones act as a reservoir for minerals, particularly calcium and phosphorus, which are essential for various bodily functions and can be released into the bloodstream as needed.
