Sorry you've not had any responses about this. :frown:

Are you sure you've posted in the right place? :smile:

Here's a link to our subject forum which should help get you more responses if you post there. :redface:

You can also find the Exam Thread list for A-levels here and GCSE here. :dumbells:

Just quoting in Puddles the Monkey so she can move the thread if needed :h:

Endothelium is very specialised and usually lines organs that come in contact with blood. It has several properties like preventing coagulation. The epithelium on the other hand lines surfaces, it's one of the four major types of tissue, and it makes up things like the epidermis, organ tissue, lining of the urinary tract etc.

Thanks, but what is the difference between endothelial and endothelium also?

endothelial is the adjective used to describe something from the endothelium, e.g. endothelial cells= cells of the endothelium, endothelial nitric oxide= nitric oxide from the endothelium.

Endothelial tissue is a type of epithelial tissue (specifically a simple squamous epithelium) that lines vessels. So technically there is no difference between them, epithelial tissue is just a broad term for a type of tissue, and it can include endothelial tissue, secretory tissue, absorptive tissue, you get the idea

This is where ADP is made into ATP by the transfer of an inorganic phosphate from a donor molecule. For example, in glycoloysis, ATP is made because a phosphate is donated by some of the molecules in the glycolytic pathway, for example 1,3 bisphosphoglycerate donates a phosphate to ATP to form 3-phosphoglycerate :smile:

^ that should say "donates a phosphate to ADP" not ATP, sorry

What is the difference between endothelial and epithelial? "endothelial" refers to tissues which line internal surfaces while epithelial refers to tissues which are found lining inside and outside surfaces of structures in the body

and what is the difference between endothelial and endothelium?

Endothelia are membranes which line the lumens of vessels such as blood vessels, while epithelia cover the outside layers of a variety of structures. Maritsa

Not necessarily, the inside of eg the trachea and lungs is lined by epithelium, also bladder, ureters etc. In fact you have four types of tissues: epithelia, muscle, neurones/ supporting cells and connective. Everything else is a subdivision of these broad tissues, and endothelia are modified epithelia to support blood filled structures such as blood vessels and the chambers of the heart.
