The amount of time is takes between consumption of food and elimination of solid waste
What is transit time
100
This is the final stage of digestion that begins with the arrival of food in the small intestine
What is intestinal phase
100
The first organ that all water-soluble nutrients travel to
What is liver
100
The is the first organ that food touches
What is the mouth
200
This type of reaction creates chemical bonds and releases a water molecule
What is condensation reaction
200
Food is moved through the GI tract using these two types of propulsion forces
What is segmentation and peristalsis
200
this secretion of water, mucus, digestive enzymes and antibacterial agents is released from glands in the mouth and functions to soften food, making it easier to swallow
What is saliva
200
this second loop of the cardiovascular system shuttles blood between the heart and lungs
What is pulmonary loop
200
flexible organ that can stretch from 1/4 cup to 2 quarts in volume
What is the stomach
300
this type of active transport uses vesicles to carry waste out of the cell
What is exocytosis
300
The enteric nervous system is composed of these type of receptors that can detect changes in conditions
What are sensory receptors
300
this small flap of cartilage covers the trachea during swallowing
What is the epiglottis
300
these are the smallest blood vessels that allow nutrients to be exchanged
What is capillaries
300
either allows or blocks bolus from entering the stomach
What is gastroesophageal sphincter
400
these are the two ways that cells are able to communicate with each other
What are neurotransmitters and hormones
400
In addition to gastrin and secretin, this third hormone is responsible for regulating the release of chyme from the stomach into the small intestine
What is CCK
400
This hormone triggers the release of HCl into the stomach.
What is gastrin
400
the functional units of the kidney
What are nephrons
400
controls the flow of chyme from the stomach to the small intestine
What is pyloric sphincter
500
this middle layer of the GI tract lining is responsible for the supply of blood vessels that are able to absorb nutrients and circulate them away from the GI tract
What is submucosa
500
The two parts of the central nervous system
What are the brain and spinal cord
500
These sores result from a failure of the mucosal lining of the stomach and can become bloody and infected.
What is gastric/peptic ulcers
500
these receptors signal that the body is ready to eliminate waste
What are stretch receptors
500
The first of the three sections of the small intestine where the final steps of digestion occur
