Hi JD great article and I love your sense of humor! I like to get my cardio on a treadmill. I set the incline at its highest setting, speed at and do a walk for 5 minute warm-up. I then push speed to 6 and basically Sprint 40-45 seconds. I’ll do 5 sets of this keep rest to about 2 minutes between sets. I’ll work up a great sweat and be huffing and puffing when finished. I feel great afterward. I hit the iron with full body workouts training as hard and heavy as I can with 2-3 days rest between them. I’m 57 and have been at this since about age 18. I will never stop! I really enjoy the info you share.
The esophagus is a muscular tube connecting the throat (pharynx) with the stomach. The esophagus is about 8 inches long, and is lined by moist pink tissue called mucosa. The esophagus runs behind the windpipe (trachea) and heart, and in front of the spine. Just before entering the stomach, the esophagus passes through the diaphragm.
The upper esophageal sphincter (UES) is a bundle of muscles at the top of the esophagus. The muscles of the UES are under conscious control, used when breathing, eating, belching, and vomiting. They keep food and secretions from going down the windpipe.
