What else can I help you with?
What increases the surface area of certain epithelial tissues?
microvilli, tremendously increase exposed surface area in epithelial tissue.
The tissue that always has a free surface exposed to the internal or external environment?
Epithelial tissue is the type of tissue that always has a free surface exposed to the internal or external environment. This tissue serves as a protective barrier or lining for organs and cavities in the body.
Type of tissue that covers the body surface?
Epithelial tissue covers the body surface. It serves as a protective barrier against physical, chemical, and microbial damage and helps regulate the exchange of substances between the body and its environment.
Which part of the epithelial cells faces the body surface?
no bone cells provide protection and support
What side of epithelial faces the lumen?
Apical Border is the side of an epithelial cell that faces the lumen.
What is the upper free surface of all epithelial cells?
The upper free surface of all epithelial cells is known as the apical surface. This surface is exposed to the body exterior or to an internal cavity or lumen, playing a critical role in functions such as absorption, secretion, and sensation. The apical surface can have specialized structures, such as microvilli or cilia, that enhance its functional capabilities. In contrast, the opposite side of the epithelial layer, which is anchored to the underlying tissue, is called the basal surface.
How is Epithelial cell in intestinal track?
Epithelial cells cover the surface of the intestine.
What increases the surface area of certain epithelial tissues?
microvilli, tremendously increase exposed surface area in epithelial tissue.
What two factors determine the distance from the free surface to the basal surface in epithelial tissue?
The presence of different types of cells and their positioning within the epithelial layer determine the distance from the free surface to the basal surface in epithelial tissue. Additionally, the function of the epithelial tissue in a specific organ or structure can influence the thickness of the tissue layer.
Type of tissue that covers the body surface?
Epithelial tissue covers the body surface. It serves as a protective barrier against physical, chemical, and microbial damage and helps regulate the exchange of substances between the body and its environment.
The tissue that always has a free surface exposed to the internal or external environment?
Epithelial tissue is the type of tissue that always has a free surface exposed to the internal or external environment. This tissue serves as a protective barrier or lining for organs and cavities in the body.
What makes a cilated epithelial cell specialized?
Ciliated epithelial cells are specialized due to the presence of numerous hair-like structures called cilia on their apical surface. These cilia beat in coordinated waves, facilitating the movement of substances such as mucus, pathogens, and debris across the epithelial surface, which is particularly important in respiratory and reproductive tracts. Their unique structure and function enable efficient clearance of particles and contribute to processes like ovum transport in the female reproductive system. This specialization enhances the protective and functional capabilities of the epithelial tissue in various organs.
New surface epithelial cells and epithelial cells lining the intestines are derived from where?
New surface epithelial cells are derived from stem cells located in the basal layer of the epithelium. Epithelial cells lining the intestines are derived from stem cells located in the intestinal crypts.
Tissue that covers and protects the body's surface?
epithelial
How can you tell epithelial tissue from other tissue?
Epithelial tissue has a free surface, a basement membrane, and little intercellular material.
What are found on the surface of the cell?
Skin cells. Epithelial cells
What type of tissue has an apical and basal surface?
Epithelial tissue lines body surfaces and cavities as have apical and basement sides.
