Esophagus
The structure joining the pharynx to the stomach is the esophagus. It is a muscular tube that helps transport food and liquids from the mouth to the stomach through a process called peristalsis.
The muscular system enables movement of the skeletal system while the skeletal system provides structure for the muscular system.
The cardiac sphincter.
The lower esophageal sphincter is the structure the keeps acid and stomach contents from spurting up the esophagus as the stomach undergoes muscular contractions. This structure is also referred to as the cardiac sphincter.
The stomach stretchy muscular sac holds food.
The muscular structure of the stomach allows it to churn and mix food thoroughly with gastric juices, which contain hydrochloric acid and digestive enzymes. This acidic environment (with a pH around 1.5 to 3.5) is inhospitable to many bacteria, effectively killing or inhibiting their growth. Additionally, the muscular contractions help to break down food particles, further enhancing the stomach's ability to eliminate pathogens. Together, these features make the stomach a crucial barrier against harmful microorganisms.
Yes. The stomach is a muscular organ.
The stomach has to be very muscular in order to with stand the acid inside and to stretch to allow food in.
