2. Riboflavin - Wikipedia

   en.wikipedia.org/wiki/Riboflavin

   Riboflavin is reversibly converted to FMN and then FAD. From riboflavin to FMN is the function of zinc-requiring riboflavin kinase; the reverse is accomplished by a phosphatase. From FMN to FAD is the function of magnesium-requiring FAD synthase; the reverse is accomplished by a pyrophosphatase. FAD appears to be an inhibitory end-product that ...

3. Adrenergic receptor - Wikipedia

   en.wikipedia.org/wiki/Adrenergic_receptor

   blood vessels of ciliary body and (stimulation of dilator pupillae muscles of iris causes mydriasis) Actions also include glycogenolysis and gluconeogenesis from adipose tissue and liver; secretion from sweat glands and Na + reabsorption from kidney. [19] α 1 antagonists can be used to treat: [7]

4. Beta-2 adrenergic receptor - Wikipedia

   en.wikipedia.org/wiki/Beta-2_adrenergic_receptor

   The beta-2 adrenergic receptor (β 2 adrenoreceptor), also known as ADRB2, is a cell membrane-spanning beta-adrenergic receptor that binds epinephrine (adrenaline), a hormone and neurotransmitter whose signaling, via adenylate cyclase stimulation through trimeric G s proteins, increases cAMP, and, via downstream L-type calcium channel interaction, mediates physiologic responses such as smooth ...

5. Vascular smooth muscle - Wikipedia

   en.wikipedia.org/wiki/Vascular_smooth_muscle

   Vascular smooth muscle contracts or relaxes to change both the volume of blood vessels and the local blood pressure, a mechanism that is responsible for the redistribution of the blood within the body to areas where it is needed (i.e. areas with temporarily enhanced oxygen consumption).

6. Flavin mononucleotide - Wikipedia

   en.wikipedia.org/wiki/Flavin_mononucleotide

   Flavin mononucleotide (FMN), or riboflavin-5′-phosphate, is a biomolecule produced from riboflavin (vitamin B 2) by the enzyme riboflavin kinase and functions as the prosthetic group of various oxidoreductases, including NADH dehydrogenase, as well as a cofactor in biological blue-light photo receptors.

7. Blood vessel - Wikipedia

   en.wikipedia.org/wiki/Blood_vessel

   Blood vessels function to transport blood to an animal's body tissues. In general, arteries and arterioles transport oxygenated blood from the lungs to the body and its organs, and veins and venules transport deoxygenated blood from the body to the lungs. Blood vessels also circulate blood throughout the circulatory system.

8. Hemodynamics - Wikipedia

   en.wikipedia.org/wiki/Hemodynamics

   Hemodynamics explains the physical laws that govern the flow of blood in the blood vessels. Blood flow ensures the transportation of nutrients, hormones, metabolic waste products, oxygen, and carbon dioxide throughout the body to maintain cell-level metabolism, the regulation of the pH, osmotic pressure and temperature of the whole body, and ...

9. Microcirculation - Wikipedia

   en.wikipedia.org/wiki/Microcirculation

   Most vessels of the microcirculation are lined by flattened cells of the endothelium and many of them are surrounded by contractile cells called pericytes.The endothelium provides a smooth surface for the flow of blood and regulates the movement of water and dissolved materials in the interstitial plasma between the blood and the tissues.
