Halley — the traditional pronunciation of the name usually rhymes with valley — was born Nov. 8, 1656, in Haggerston, Shoreditch, London, England. His father was a prosperous soapmaker and property owner. Halley was tutored privately at home before entering St. Paul's School, where he excelled in mathematics and astronomy.

Halley entered Queen's College, Oxford, in 1673, when he was 17 years old. He brought with him a fine collection of astronomical instruments purchased by his father. While still an undergrad, he became a protégée of John Flamsteed, the Astronomer Royal.

Which statement below is correct about the digestive system?
denis23 [38]

The right answer is B) Specialized tissues come together to create the stomach, which is an organ.

* Cells linked to each other form a set called tissue. The cells composing a tissue are not all identical, but they work together to provide a specific function.


* Each organ is a recognizable structure (eg, heart, lungs, liver, eyes, stomach) that provides a specific function. An organ consists of different types of tissues and, therefore, different types of cells.

The stomach is a thoraco-abdominal organ, located in the abdomen and in contact with the chest wall.

The stomach is a dilated segment of the digestive tract located between the esophagus and the duodenum. Its main function is to turn the food bolus into a mixture called gastric chyme.

The stomach is composed of two parts, two sides (anterior and posterior), two edges (small and large curvature) and two orifices (the cardia, upper orifice, and the pylorus, lower orifice).
