__________ makes up the intervertebral disc; whereas, __________ makes up the costal cartilage between the ribs and sternum

A. aids in digestion:Ciliated pseudostratified columnar epithelium is not involved in digestion. Digestive functions are primarily handled by simple columnar epithelium in the gastrointestinal tract.

B. is more durable than all other epithelia:While pseudostratified epithelium provides some protection, it is not the most durable epithelium. Stratified squamous epithelium is better suited to withstand abrasion and mechanical stress.

C. is found in some of the larger glands:Some simple columnar or cuboidal epithelia line glands, but ciliated pseudostratified columnar epithelium is not characteristic of glandular linings.

D. lines most of the upper respiratory tract:The ciliated pseudostratified columnar epithelium with goblet cells lines the nasal cavity, trachea, and bronchi. The cilia move mucus and trapped particles toward the throat, helping to clean and protect the respiratory system.

A. blood and hyaline cartilage:Blood contains plasma and cells but very few fibers, and hyaline cartilage is mostly composed of a smooth extracellular matrix with limited collagen fibers. These tissues do not have abundant collagen.

B. ligaments, bones, and the superficial portion of the skin:While ligaments and bones contain collagen, the superficial portion of the skin (epidermis) is mostly epithelial tissue with minimal collagen, making this pairing inaccurate.

C. tendons, ligaments, and the deeper portion of the skin:Tendons and ligaments are rich in collagen fibers, which provide tensile strength. The deeper portion of the skin, the dermis, also contains abundant collagen, supporting skin structure and elasticity.

D. areolar tissue, tongue, and bones:Areolar tissue has loosely arranged collagen fibers, and the tongue contains muscle tissue interspersed with connective tissue, so collagen is present but not as abundant as in tendons and ligaments.

E. blood, adipose tissue, and osseous tissue:Blood and adipose tissue contain very few collagen fibers, while osseous tissue contains collagen within its mineralized matrix, making this combination inaccurate for abundant collagen.
