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.
because it has a complete muscular layer around it
yea your deltoids are muscles around your shoulders
The heart is a muscle that pumps blood around the body.
Muscular tissue is found throughout the body, attached to bones for movement (skeletal muscle), around internal organs for contraction (smooth muscle), and making up the heart for pumping blood (cardiac muscle).
Because you run around and chase the ball a lot.

Natural pearlsContrary to popular belief, a natural pearls is notformed by a grain of sand. This story is an urban legend.A natural pearl forms inside a bivalve mollusk when the shell has been invaded by a parasite or damaged. The most common reason a natural pearl will develop is due to parasitic invasion.The parasite wil burrow through the periostracum layer (outer layer) of a mollusk shell and into the mother-of-pearl beneath. When the parasite penetrates the mother of pearl in comes in contact with the mollusk's mantle muscle. This muscle contains cells known as epithelial cells. These cells produce a substance called nacre which coats the inside of the shell (mother-of-pearl) and is the substance of which a pearl is composed.The parasite becomes lodged in this mantle muscle and dies. The mollusk's definsive reaction is to grow a sac around the intruder. This sac is called the pearl sac. Once the sac encases the intruder the cells begin to deposit nacre- which is composed of aragonite and calcite (a calcium carbonate compound) platelets.Cultured PearlsCultured (marine) pearls are grown by inserting a rounded bead of mother-of-pearl and a piece of mantle tissue containing epithelial cells from a donor mollusk into the gonad, or reproductive organ, of a host mollusk. The donor tissue grows into a pearl sac around the bead. As in natural pearl production, this sac then deposits nacre.Maturity time of artificial oyester pearl
Scungili is the meat from a large sea mollusk/snail that probably lives in and around the waters of NJ. This delight is mostly limited to Italian eateries in and around Northern NJ. It comes as a salad or in a red sauce.
I don't think it has a picture because it has something to do with air around us.
The middle of a pearl is called the nucleus, which is typically a small, round object made of calcium carbonate or an organic material around which the pearl forms. As an irritant, it triggers the oyster or mollusk to secrete layers of nacre, or mother-of-pearl, which gradually builds up around the nucleus, creating the pearl's lustrous surface. The composition and structure of the nucleus significantly influence the pearl's size, shape, and overall quality.
