Plasma of blood contains proteins, salts, and hormones, serving as a medium for transporting nutrients, gases, and waste products.

Red blood corpuscles (RBCs), white blood corpuscles (WBCs), and platelets are suspended in the plasma of blood.

The fluid matrix of blood is called plasma, comprising proteins, salts, and hormones, where blood cells are suspended.

Connective tissue cells provide structural support, help maintain tissue integrity, and contribute to the overall organization and function of organs and systems in the body.

The nature of the matrix in connective tissue determines its overall function and properties, such as support, flexibility, or protection.

The matrix of connective tissue may be jelly-like, fluid, dense, or rigid, depending on the specific function of the tissue.

Connective tissue cells are loosely spaced and embedded in an intercellular matrix.

Glandular epithelium forms when a portion of the epithelial tissue folds inward, resulting in the formation of multicellular glands capable of secreting substances.

Epithelial cells can undergo specialization to become gland cells, which secrete substances at the epithelial surface.

Cuboidal epithelium provides mechanical support in structures such as kidney tubules and salivary gland ducts.
