NUR 2063 module 3 Questions with Correct Answers |New Update 100% Verified By Experts
What is the function of the mitochondria? Produces ATP, the cell's energy source.
What do lysosomes do? Digest cellular debris and metabolize substances.
Role of the Golgi apparatus? Prepares substances for secretion.
What does the endoplasmic reticulum do? Produces proteins/fats and regulates ions in the
cell.
What's the job of peroxisomes? Neutralize free radicals and toxic substances.
What is phagocytosis? Ingestion of large particles like bacteria.
What is exocytosis? Expelling waste and debris from the cell.
What is cell respiration? Converts fuel into ATP and waste — essential for cell survival.
What is differentiation? When cells develop specific structures/functions.
What is atrophy? Decrease in cell size (e.g., due to disuse or ischemia).
What is hypertrophy? Increase in cell size (e.g., heart muscle from hypertension).
What is hyperplasia? Increase in the number of cells (e.g., endometrial thickening).
What is metaplasia? Change of one cell type into another (e.g., in GERD).
, What is dysplasia? Abnormal size/shape/organization of cells; may lead to cancer.
What is apoptosis? Programmed cell death (clean and orderly).
What is necrosis? Disorderly cell death with inflammation (injury-related).
What are the causes of cell injury (TIPS)? Toxins
Infections
Physical injury
Serum deficit (nutrition, oxygen)
What causes acute sinusitis? Viral infection with mucus blockage.
Key signs of sinusitis? Facial pain, congestion, fever, postnasal drip.
What bacteria causes chronic gastritis? H. pylori — can lead to ulcers and gastric cancer.
What is steatorrhea and what condition is it linked to? Fatty stools; linked to chronic
pancreatitis or Crohn's.
What parts of the GI tract does Crohn's disease affect? Mostly small intestine and ascending
colon (patchy).
What are skip lesions? Patchy areas of inflammation with healthy tissue in between.
What's a major complication of Crohn's? Fistulas, bowel obstruction, malabsorption.
