Vein limbs. The Thebesian veins within the myocardium of the heart are valveless veins that drain directly into the chambers of the heart. The coronary veins all empty into the coronary sinus which empties into the right atrium. The dural venous sinuses within the dura mater surrounding the brain receive blood from the brain and also are a point of entry of cerebrospinal fluid from arachnoid villi absorption. Blood eventually enters the internal jugular vein. "Phlebology" is the medical specialty devoted to the diagnosis and treatment of venous disorders. A medical specialist in phlebology is termed a phlebologist. A related image
The Heart Attack Chuckle. They stop the ambulance to fight outside. The driver beats the EMT bloody and leaves him in the street. While arguing with the passengers over this, he takes his eyes off the road, causing a crash. George and Jerry are put in neck braces and George has the tonsillectomy. Elaine visits briefly to give George some ice cream. The hospital television shows "The Flaming Globes of Sigmund" again, and Jerry remembers that what he wrote down was a line from the movie. As he realizes this, he notes "That's not funny." "The Heart Attack" was written by Larry Charles.
