Physio organ slides

Question 1

Answer 1

BLADDER - transitional epithelium underlaid with layers of smooth muscle

Question 2

Answer 2

COLON- regularly shaped vili are folds of simple columnar ep, lots of goblet cells (tiny white blobs) for mucus secretion

Question 3

Answer 3

DUODEUNUM- big, irregularly shaped vili for surface area - made of folded simple columnar epithelium. Small white bubbles are goblet cells - mucus producers. Fewer and smaller goblet cells than large intestine.

Question 4

Answer 4

ESOPHAGUS - stratified squamous epithelium lines lumen, submucosa is areolar CT with muscle

Question 5

Answer 5

KIDNEY (10x) - glomeruli are the chunks of cells. Collecting ducts are simple cuboidal epithelium.

Question 6

Answer 6

Kidney (40x)

Question 7

Answer 7

LIVER - Hexagonal arrangement is lobule made of radiating hepatocytets, space is central vein, which leads to hepatic vein to vena cava. Corners of hexes are arterial veins, portal venule, bile duct.

Question 8

Answer 8

ALVELOLI - simple squamous epithelium and pulmonary capillaries

Question 9

Answer 9

BRONCHIOLE - pseudostratified epithelium lines lumen (not squamous, because too thick) plus smooth muscle and CT

Question 10

Answer 10

MONOCYTE (very large, kidney-shaped nucleus, gray-blue cytoplasm)

Question 11

Answer 11

NEUTROPHIL (chunky, multi-lobed nucleus) and bigger than lymphocyte) and LYMPHOCYTE (just a bit bigger than RBC, mostly nucleus with a bit of cytoplasm)

Question 12

Answer 12

PANCREAS - islet cell (endocrine) is finer-textured, acinar cells (exocrine - make digestive enzymes) are chunkier. Acinar cells feed ducts - big circles - lumen lined with simple columnar ep, surrounded by smooth musc

Question 13

Answer 13

RBCs and Platelets

Question 14

Answer 14

STOMACH - serrated-looking folds facing lumen are gastric pits, folded columnar epithelium, above the subdivide into gastric gland. Deeper glands with diff cell types are the speckly bits

Question 15

Answer 15

TRACHEA- psueudostratified ciliated columnar epithelium, submucosa with seromucus glands, and hyaline cartilage
