a&p II test 4

A glomerulus is

a knot of capillaries within the renal corpuscle.

A patient excretes a large volume of very dilute urine on a continuing basis. This is may be due to

absence of ADH

The primary function of the proximal convoluted tubule is

absorption of ions, organic molecules, vitamins, and water

The digestive tract is also referred to as the

alimentary canal and the GI tract.

If the pancreatic duct was obstructed, you would expect to see elevated blood levels of

amylase

Each of the following organs is a component of the digestive tract, except the

bladder

The part of the stomach that functions as a mixing chamber for food and secretions is the

body

The bulk of each tooth consists of a mineralized matrix similar to that of bone called

dentin

The portion of the nephron that empties into the collecting duct is the

distal convoluted tubule

The pylorus empties into the

duodenum

The gastric phase of gastric secretion is triggered by the

entry of food into the stomach

The urinary system does all of the following, except that it

excretes excess albumen molecules

Blockage of the common hepatic duct would interfere with digestion of

fats

G cells of the stomach secrete

gastrin

The portion of the small intestine that attaches to the cecum is the

ileum

The renal veins drain into the

inferior vena cava

The layer of loose connective tissue that directly supports the digestive epithelium is the

lamina propria

Carbohydrate digestion begins in the

mouth

The roof of the oral cavity is formed by the

palatine processes of maxillary bones, palatine bones, soft palate, hard palate

Which of the following is an accessory organ of digestion?

pancreas

The ________ gland empties into the oral cavity at the level of the second upper molar.

parotid

Waves of muscular contractions that propel the contents of the digestive tract are called

peristalsis

Capillaries that surround the proximal convoluted tubules are

peritubular capillaries

The uvula is located at the

posterior margin of the soft palate

Each of the following is a normal constituent of urine, except

proteins

The enzyme pepsin digests

proteins

Filtrate first passes from the glomerular capsule to the

proximal convoluted tubule

The region of the stomach that empties into the duodenum is the

pylorus

Approximately the last 15 cm of the digestive tract is the

rectum

Glomerular (Bowman's) capsule and the glomerulus make up the

renal corpuscle

The cavity of the kidney that receives urine from the calyces is called the

renal pelvis

The expanded beginning of the ureter connects to the

renal pelvis

Functions of the large intestine include

resorption (absorption) of water and compaction of feces

In response to the hormone cholecystokinin, the pancreas secretes a fluid

rich in enzymes

The prominent ridges in the lining of the empty stomach are called

rugae

The intestinal hormone that stimulates the pancreas to release a watery, bicarbonate-rich fluid is

secretin

The ability to form concentrated urine depends on the functions of

the loop of Henle and the collecting duct

Which of these enhance the absorptive effectiveness of the small intestine?

the villi, microvilli, intestinal movements, the plicae circulaes

The ureters and urinary bladder are lined by ________ epithelium

transitional

An enzyme that digests proteins into peptides is

trypsin

An obstruction of the common bile duct often results in

undigested fat in the feces

Urine is eliminated through the

urethra

In response to increased levels of aldosterone, the kidneys produce

urine with a lower concentration of sodium ions

________ pair(s) of salivary glands secrete into the oral cavity.

3

Put the following layers of the digestive tract wall in order from the lumen to the deepest layer: 1. lamina propria 4. digestive (mucous) epithelium 2. muscularis externa 5. serosa 3. submucosa 6. muscularis mucosae

4, 1, 6, 3, 2, 5

The saclike structure that joins the ileum at the ileocecal valve is the

cecum

The root of a tooth is covered by

cementum

Substances secreted by the distal convoluted tubule include

creatinine, penicillin, hydrogen ions, potassium ions

Large blood vessels and lymphatics are found in the

submucosa

The left kidney lies ________ to the right kidney

superior
