How does gastrointestinal tract evade dehydration?
1)
Alternating wave-like contraction and relaxatio of the oral (mouth) muscles reabsorbs water which will be transported to the urinary system
2) water is an important digestive enzyme in the stomach.
3) Normal peristaltic movements in the large intestine ensure reabsorption of water that will be delivered to the circulatory system.
4) the water we drink will be mostly absord by the blood vessels attached to the esophagus and stomach.

. (a) What is the order of magnitude of the number ofmicroorganisms in the human intestinal tract? A typical bacterial length scale is 1026 m. Estimate the intestinal volume and assume 1% of it is occupied by bacteria. (b) Does the number of bacteria suggest whetherthe bacteria are beneficial, dangerous, or neutral forthe human body? What functions could they serve?
Regional movements that occur in the small intestine and function to churn and fragment the digestive materials
are called
O a) Peristalsis
O b) Segmentation
O c) Diffusion
O d) Churning movements
O e) Waves
