🔬 Epithelial Tissues:

Frog Kidney Epithelium: Displays tightly packed cuboidal epithelial cells, ideal for secretion and absorption functions in the renal tubules.
Squamous Epithelium: Characterized by its thin, flat cells arranged in layers, perfect for facilitating diffusion and filtration processes.
Cuboidal Epithelium: Cube-shaped cells with a central nucleus, commonly found in glands and ducts, playing a crucial role in secretion and absorption.
🧬 Connective Tissues:

Embryonic Tissue (Mesenchyme): The primitive, undifferentiated tissue with star-shaped cells suspended in a gel-like ground substance, giving rise to all connective tissues.
Hyaline Cartilage: Smooth and glassy with a translucent matrix, providing structural support and flexibility in joints, the respiratory tract, and the nose.
Elastic Cartilage: Packed with elastic fibers, offering both strength and flexibility, commonly found in the ear and epiglottis.
