Yes! avascular means without blood vessels.
No it has no vascularization, with one exception. It gets it's vascularization from the connective tissue upon which it rests.
Epithelial tissue cells are avascular so they are nourished by substances diffusing from blood vessels in the underlying connective tissue.
Oxygen is diffused through the basal lamina.
blood vessels in the underlying connective tissue do not penetrate the basement membrane to reach the epithelium
No. It's included with connective tissue.
no
yes
the epithelial system is a system in your body. It is made from Skin cells. A group of skin cells make epithelial tissue. Epithelial tissue makes the epithelial system.
ciliated epithelial tissue
A group of epithelial cells organized to perform a common function would be a tissue.
epithelial cells of the semiinferous tubules.
Blood id the tissue that carries oxygen to cells in body . Blood is a liquid connective tissue . It possess RBC which contain hemoglobin . Hemoglobin binds with oxygen and transports it .
whereas most tissue are vascular (contain blood vessels), epithelium is avascular, meaning it lacks blood vessels. epithelial cells receive their nutrients from capillaries in the underlying connective tissue. although blood vessels do not penetrate epithelial sheets, nerve endings do; that is, epithelium is innervated (supply organ with nerve).
epithelial tissue
Simple epithelial tissues have no blood vessels and line or cover structures.
the epithelial system is a system in your body. It is made from Skin cells. A group of skin cells make epithelial tissue. Epithelial tissue makes the epithelial system.
The membranes that do not contain gland cells are called basement membranes. These basement membranes line the interiors of blood vessels and the skin.
Epithelial tissue are closely connected and have a basal membrane, even though not all epithelial cells are necessarily connected to the basal membrane. The so called simple epithelial tissue subgroup does.
Epithelial cells are the lining cells. they are not a tissue. this is to be understood first. the outermost lining is known as the epithelial cell lining. it is provided its nutrition through diffusion- indirectly through blood. BUT they DO NOT have a blood vessel supply, since they are not an organ/tissue, just a cell lining.
Epithelial tissue consists of sheets of cells.
Simple epithelial tissues have no blood vessels and line or cover structures.
Skin tissue
Epithelial tissue is found throughout the body in your skin, organs and cells.
