Scrotum is a place to accommodate testicles. It can swell and contraction with temperature changes.The nutritional supply of the testicles is transported by the arteries of the testicles, but the blood return is borne by the vein. Coupled with a pipeline (vas deferens) that transports semen, the three pipes are wrapped into a cable -shaped tissueStructure is called sperm.When the venous blood vessels in the sperm cable expand and pedantic due to some reasons, the "green tendon" is revealed on the scrotum.Medical is known as the iconic veins.
What is the "blue tendon" on the scrotum?
Xiao Li suddenly discovered that there were many "blue tendons" like earthworms in the scrotum skin.Especially when the scrotum was loosened on the hot day, the "blue tendon" was more clear.Through the thin skin, it seemed that the "blue tendon" was so angry that it would be cracked, which was uneasy.
There is a distant "road" to go from the testicular vein flowing blood. If the blood vessels in the blood vessels have poor development and the test of the years, some blood vessel petals will be damaged or incomplete.Blood reflux disorders occur, blood stasis is accumulated in the sperm vein of the scrotum, which makes the blood vessels expand and pedantic, forming the so -called spermatic veins.
When the human body stands, the flow of arterial blood flows from top to bottom. It looks relaxed and natural. The blood source that enters the testicles continues to enter the testicles, and the venous blood from the bottom to the top is not so smooth.Because blood is attracted to the earth, flowing from bottom to top looks very laborious and slow.
