B. Guided Tour of the Digestive System

Toews MPH, Victoria Dolby Basic Health Publications ePub

APPENDIX B

Heres a refresher about the basic process of digestion. The digestive system has several parts that all work in concert for the goal of digesting and absorbing food. The breakdown of food occurs in the stomach (gastro) and the intestine, which is why it is also called the gastrointestinal (GI) tract. The GI tract can be thought of as an approximately 16.5 feet long tube extending from the mouth to the anus. It includes the mouth, esophagus, stomach, small intestine, pancreas, gallbladder, liver, and large intestine.

The whole system starts to work as soon as a bite of food enters the mouth. The process of chewing mashes the food into smaller, more manageable pieces. Next, the food is swallowed, meaning that it travels down the esophagusa tube that connects the mouth to the stomach. A series of wavelike contractions keep the food moving down to the stomach and through the rest of the GI tract.

Once in the stomach, the powerful muscles of the stomach churn the food, breaking it into smaller and smaller pieces. Gastric juices produced by the glands lining the stomach mix with the food particles. These juices contain pepsin, an enzyme that begins to digest proteins, and hydrochloric acid to acidify the stomach. Very few foods are actually absorbed in the stomachonly alcohol, simple sugars, and some medicationsthe rest of the nutrient absorption takes place later in the digestive tract.

Abstract

As a preliminary step in the selection of germplasm for heavy clay soils in the Australian tropics and subtropics a review was undertaken of known genera and species of leguminous plants with known and suspected potential.

Groupings were made of the genera based on the percentage of species occurring on clay soils. Assessments were then undertaken of their interest based on the environments in which they occur and their general forage characteristics. The report concludes with brief comments about the adequacy of genetic resource collections of the genera and species that have proven to be of value.

6.1  Introduction

Almost all Australian pasture legume cultivars are plants that have been introduced from elsewhere, and all crop varieties are ‘aliens’, with the sole exception of the Macadamia nut, which is native to Queensland but was developed for commercial use in the USA. This is not altogether surprising because Australian flora is unique since it has been long isolated from those regions in which the seed-bearing plants developed, and thus has relied on the evolution of endemic plants to cope with the ever-changing climate and decreasing levels of soil fertility. The dry areas of Australia illustrate the adaptations that have been necessary (White, 1994). There the soils are poor and sclerophyll–xerophyte grasslands

4. “What Should We Collect?”: Ethnography, Local Studies, and the Formation of a Belorussian Jewish Identity

Jeffrey Veidlinger Indiana University Press ePub

ELISSA BEMPORAD

I began to collect songs, stories, and jokes among the bal-melokhes, the artisans. . . . I passed through the neighborhood of Novokrasnaia, by the houses of ill repute, then by the cemetery, and between the Vilna and Brest train stations, where the balegoles, or carters, lived. I remember the streets that connected Nemiga to the High Market, with crowds of Jewish brush-makers, shoemakers, carpenters, tailors, chimney sweepers, bakers, glaziers . . . and the painters who had coated the [city’s] roofs . . . in green or red; . . . this was the large tkhum ha-bal-melokhes, the “Pale of the Artisans.” I went there to collect folklore. . . . There were so many songs, Jewish folk songs, I wrote down the text but I could never remember the melodies, so another young man came and collected the nigunim, the melodies. . . . You could hear them everywhere, the songs. . . . It wasn’t hard to find them, as the bal-melokhes sang constantly. . . . It was harder to find the stories. . . . [I would approach] the balegoles, [but not on shabes,] for them shabes was shabes, but on motsei shabes when they would come together. . . . The best stories I found among the older shoemakers . . . and by Mume Reyze, a zogerke [a prayer-leader in the synagogue women’s section], . . . who was a source of storytelling. . . . These places were somewhat strange for me, I discovered a world. . . . I even visited the zogerke on shabes, when many youngsters would gather to listen to her stories.1

Seven Deadly Sins

Phil Lapworth Karnac Books ePub

I wake myself up screaming “No!” and lie there trembling for some minutes trying to remember what I've been dreaming about. But dreams need to be exited slowly and gently if their convoluted meanderings are to be transmitted from unconscious imagination to a conscious mind seeking sense. My sudden awakening erases all trace of what has been going on in my fantasy world, leaving only a sense of having been through something challenging. Whatever it was that had led to my frightened and imploring scream is not forthcoming despite my attempts to insert possibilities—hooded attackers, stampeding monsters, devastating news—into the void.

It's not a good start to a busy day, and the feelings of dread and frustration remain with me as I dress quickly, breakfast on the hoof, and read through my emails, most of which I condemn to the trash without the usual satisfaction I get from hearing the scrunching sound as they disappear. Even walking through the woods with my dog in the bright morning sunlight does not manage to alleviate my disturbed state as it normally might. I just have to hope I can bracket off this sense of unease well enough to work with my clients.
