Circulatory terms

Question 1

angiogenesis

Answer 1

ngiogenesis is the physiological process through which new blood vessels form from pre-existing vessels, formed in the earlier stage of vasculogenesis. Angiogenesis continues the growth of the vasculature by processes of sprouting and splitting

Question 2

reticulin

Answer 2

Reticulin is a histological term used to describe a type of fiber in connective tissue composed of type 3 collagen in which these reticular fibers crosslink to form a fine meshwork.

Question 3

glycoproteins

Answer 3

molecules that comprise protein and carbohydrate chains that are involved in many physiological functions including immunity

Question 4

fibronectin

Answer 4

a high-molecular weight (~500-~600 kDa) glycoprotein of the extracellular matrix that binds to membrane-spanning receptor proteins called integrins

Question 5

laminin

Answer 5

glycoproteins with both common and specific functions

Question 6

glycosaminoglycans

Answer 6

also known as mucopolysaccharides, are negatively-charged polysaccharide compounds

Question 7

proteoglycans

Answer 7

a group of molecules that possess a protein core and a side chain of sugars

Question 8

Stroma

Answer 8

the connect-tissue framework of organs

Question 9

Colloidal pressure

Answer 9

the osmotic pressure exerted by large molecules, serves to hold water within the vascular space. It is normally created by plasma proteins, namely albumin, that do not diffuse readily across the capillary membrane.
