What does the accessory glands include? Salivary gland, liver, gallbladder, pancrease
What does the accessory glands do? The secrete digestive enzymes into the alimentary canal
What is the alimentary canal? A musculomembranous tube that extends from the mouth to the anus
How long is the great part of the alimentary canal and where does it lie? 29 to 30 feet(8.6 to8.9 cm) long and is int the abdominal cavity
What are the component parts of the alimentary canal and what are their functions? Mouth/food is masticated &converted into bolus by salivation-pharynx/esophagus/these organs are used for swallowing-stomach/digestion starts-small intestine/digestion complete-large intestine/the organ of ingestion and water then it terminates at the-anus
What is the esophagus? Large muscular tube that carries food and saliva from the laryngopharynx to the stomach
How long is the adult esophagus? 10 inches long and 3/4 inch in diameter
What are the walls of the esophagus made of? Outward to inward/ fibrous layer, muscular layer, submucosal layer, and mucosal layer
Where does the esophagus lie? In the midsagittal plane level of 6th c-spine or upper thyroid cartilage
Where does the esophagus enter and pass through the upper portion? Enters at the thorax and passes through the mediastinum, anterior to the vertebral bodies and posterior to the trachea and heart
Lower portion of the esophagus passes through what? The diaphragm at T-10 the inferior to the diaphragm the esophagus curves sharply left, increases diameter; joins the stomach at the esophagogastric junction which is at the level of the xiphiod tip or T11
What is the expanded portion of the terminal esophagus which lies in the abdomen called? Cardiac Antrum
What's the dilated, saclike portion of the digestive tart extending between the esophagus and the small intestine called? Stomach
What are the walls of the stomach made of? Outward to inward/ fibrous layer, muscular layer, submucosal layer, and mucosal layer
What are the four parts that make up the stomach? Cardia, fundus, body, and pyloric portion
This is the section of the stomach immediately surrounding the esophageal opening. Cardia
This is the superior portion of the stomach that expands superiorly and fills the dome of the left hemidiaphragm. Fundus
Descending from the fundus and beginning at the level of the cardiac notch is the Body of the stomach
Distal to the vertical plane is what portion of the stomach? Pyloric portion
Wen the patient is in an upright position the fundus is usually filled with what? Gas or gas bubble
The mucosal layer of the body of the stomach contains numerous longitudinal folds called Rugae
When the stomach is full how is the rugae? Smooth
What does the pyloric portion of the stomach contain? Pyloric Antrum to the right of the angular notch and the narrow pyloric canal communicating with the duodenal bulb
The right border of the stomach is marked by what? Lesser curvature which begins at the esophagogastric junction and to the right border of the esophagus ending at the concave curve of the pylorus
The left and inferior borders of the stomach are marked as Greater curvature beginning at the esophagogastric junction, cardiac notch and follows the superior curvature of the fundus and then the convex curvature of the body down to the pylorus
Which is larger the lesser or greater curvature and by how much? Greater curvature by 4 to 5 times longer
What is the entrance to and exit from the stomach controlled by? A muscle sphincter
The esophagus joins the stomach at the esophagogastric junction through an opening called what? And what controls this? Cardiac orifice ;cardiac sphincter
The opening between the stomach and small intestine is called what and what controls it? Pyloric orifice ; pyloric sphincter
The size, shape, and position of the stomach depends on what? The body habitus
What habitus is the stomach almost horizontal and is high, with its dependent portion well above the umbilical area? Hypersthenic
What body habitus is the stomach vertical and occupies a low position , with its dependent portion extending well below the transplyoric or interspinous, line? Asthenic
What is the body habitus of 85% of the population? Sthenic or hyposthenic
5% of the population is what type of body habitus? Hypersthenic
50% of the population has what type of body habitus? Sthenic
35% of the population has what type of body habitus? Hyposthenic
10% of the population has what type of body habitus? Asthenic
