What blood vessels directly supply oxygenated and deoxygenated blood to the kidneys?
The renal arteries carry blood from the heart to your kidney.
What larger blood vessels do these kidney vessels branch from?
renal artery
What are the 6 main regions of the colon?
cecum, ascending colon, transverse colon, descending colon, sigmoid colon, and the rectum
What are the 2 flexures called? What abdominal regions are they located in?
There are two colic flexures, or curvatures in the transverse colon. The right colic flexure is also known as the hepatic flexure, and the left colic flexure is also known as the splenic flexure.
Identify the gross anatomy of the outside stomach: body, greater curvature, lesser curvature,
pylorus, fundus
What epithelium is found in the small intestine?
simple columnar epithelium
What are the 3 regions of the small intestine?
Duodenum
Jejunum
Ileum
What abdominal region is the liver in? What about the pancreas, stomach, and colon sections?
The liver is located in the right hypochondria region and the epigastric, as well as the right kidney, the gallbladder, and the large/small intestine. The pancreas, the colon, and the stomach are located in the left hypochondria region. The colon is also located in the left lumbar region.
Name the valve that separates the small intestine from the large intestine. Be able to identify it
The ileocecal valve.
Where does the greater omentum attach to?
The stomach and the transverse colon
What enzymes digests the following molecules: starch and fats.
Amylase digests starch and lipase digests fats
Identify the digestive system anatomy: mouth, pharynx, epiglottis, esophagus, stomach, small
intestine, large intestine, anus.
What epithelium is found in each of these areas?
Stratified squamous epithelium, gets to stomach is simple columnar, then to stratified squamous epithelium in anus
Biliary tree: when looking at the gallbladder, be able to identify the cystic duct and common bile
Duct
What is the wave-like contraction of muscle that propels food down the digestive tract?
Peristalsis
Know that enzymes break food down via hydrolysis
Pepsin and trypsin
Know the 2 types of digestion
Mechanical digestion:
* mechanically breaks down food for eventual chemical digestion by enzymes.
* Includes chewing, mixing food with saliva by tongue, churning food in the stomach and segmentation in the small intestine.
* involves physical movement to make foods smaller
Chemical digestion:
* chemically breaks down food via enzymes
* saliva is produced by the parotid, sublingual, and submandibular glands; it is 97-99.5% water, but also contains electrolytes, lysozyme, and the digestive enzymes salivary amylase and lingual lipase.
* uses enzymes to break down food
* hydrolysis (enzymatic) reactions
