A 79-year-old male resident of a long-term care facility has contracted clostridium difficile and is experiencing consequent dia
rrhea. auscultation of the man's abdomen indicates hyperactive bowel sounds. what process in the man's small intestine is most likely accompanying his current status? a. inflammation is accompanied by an increase in peristaltic movements of his small intestine. b. intestinal stasis brought on by infection is preventing his small intestine from sufficiently slowing the rate of motility. c. segmentation waves have become more frequent as a result of his infection. d. pathogenic microorganisms are causing dilation of his small intestine, increasing motility.
<span>The answer would be: a. inflammation is accompanied by an increase in peristaltic movements of his small intestine.
The pathogen will attract the white blood cells that will induce inflammation in the intestine. Inflammation of the intestine will cause increased permeability and increased bowel movement, makes the food transit time reduced and lead to diarrhoea. This mechanism is beneficial since it can help the intestine to "flush out" pathogen of toxins that induce the inflammation.</span>
Nucleic acids are the most important macromolecules for the continuity of life. They carry the genetic blueprint of a cell and carry instructions for the functioning of the cell. The two main types of nucleic acids are deoxyribonucleic acid (DNA) and ribonucleic acid (RNA).
Xeroderma pigmentosum arises as a result of the cell being unable to correct lesions induced by UV. This can be as a result of mutations in the enzymes which include XP A-E needed for correction of the lesions. Failure to correct these lesions leads to their accumulation and then damage to the cell.
Osmosis happens when the osmotic pressure of two container separated by semipermeable membrane is different. The osmotic pressure could be exert by polar solute because they will attract water molecule. Protein, glucose, and sodium chloride is the common molecule that could cause osmosis. But protein is the main substance that keep the osmotic pressure of the blood in the body.
