R = Resistance of blood vessel. Blood flows from area of high pressure to an area of low pressure, down the pressure gradient. When heart contracts, it gives pressure to the blood, which is main driving force for flow through a vessel.Due to resistance in the vessel, the pressure drops as blood flows. = Resistance of blood vessel.

(July 2016) I'd Rather Go Blind is a blues song written by Ellington Jordan and co-credited to Billy Foster. It was first recorded by Etta James in 1967, released in 1968, and has subsequently become regarded as a blues and soul classic.
The result of the sessions was the smash hit âTell Mama,â a song co-written by Clarence Carter. âTell Mamaâ was a Top 10 R&B record, and reached #23 on the pop chart. The B-side of that smash was âIâd Rather Go Blind.â Etta had a friend who was in prison named Ellington âFugiâ Jordan. On one visit to the prison, Jordan told her about an idea he had for a song. Etta finished the song, but gave credit to her then-partner Billy Foster (a singer in the Medallions) for tax reasons.
