The permeability of epithelial cells regulates the selective passage of substances, facilitating essential functions like nutrient absorption, waste excretion, and fluid balance in organs such as the gastrointestinal tract and kidneys. Additionally, epithelial cells form protective barriers against pathogens and toxins, crucial for maintaining tissue integrity and defending the body against infections.
Epithelial tissue cells are tightly packed and arranged in continuous sheets, forming a protective barrier on body surfaces and lining internal organs. Their characteristic feature is the presence of minimal intercellular spaces, thanks to specialized junctions like tight junctions and desmosomes. TRead more
Epithelial tissue cells are tightly packed and arranged in continuous sheets, forming a protective barrier on body surfaces and lining internal organs. Their characteristic feature is the presence of minimal intercellular spaces, thanks to specialized junctions like tight junctions and desmosomes. This arrangement ensures close cell-to-cell contact, enhancing barrier function and facilitating selective permeability.
Epithelial tissue forms the lining of various organs and structures in the body. Examples include the skin (epidermis), digestive tract (lining of the mouth, stomach, intestines), respiratory tract (lining of the trachea, bronchi), urinary bladder, reproductive tract (uterus, vagina), endocrine glanRead more
Epithelial tissue forms the lining of various organs and structures in the body. Examples include the skin (epidermis), digestive tract (lining of the mouth, stomach, intestines), respiratory tract (lining of the trachea, bronchi), urinary bladder, reproductive tract (uterus, vagina), endocrine glands (thyroid, pancreas), and blood vessels (endothelium). Epithelial tissue serves functions such as protection, absorption, secretion, and selective permeability.

Connective tissue differs from other animal tissues due to its rich extracellular matrix comprising fibers (like collagen, elastin) and ground substance. This matrix provides structural support, binds tissues and organs, cushions and insulates organs, and facilitates nutrient and waste exchange. AddRead more
Connective tissue differs from other animal tissues due to its rich extracellular matrix comprising fibers (like collagen, elastin) and ground substance. This matrix provides structural support, binds tissues and organs, cushions and insulates organs, and facilitates nutrient and waste exchange. Additionally, connective tissue participates in immune responses. Examples include bone, cartilage, adipose tissue, blood, and tendons, contributing to overall body integrity and function.
