Pathways

Question 1

O2 pathway

Answer 1

nares -> vestibule -> nasal cavity -> nasopharynx -> oropharynx -> laryngopharynx -> larynx -> trachea -> primary bronchi -> secondary bronchi -> tertiary bronchi -> bronchioles -> terminal bronchioles -> alveolar ducts -> alveolar sacs -> alveoli

Question 2

oral cavity

Answer 2

lips -> vestibule -> oral cavity -> oropharynx -> laryngopharynx -> superior esophageal sphincter -> esophagus -> inferior esophageal sphincter -> stomach -> phyloric sphincter -> duodenum -> jejunum -> ileum -> ileocecal valve -> cecum -> ascending colon -> right colic flexure -> transverse colon -> left colic flexure -> descending colon -> sigmoid colon -> rectum -> anal canal -> anus

Question 3

urine pathway

Answer 3

kidney -> ureters -> urinary bladder -> urethra

Question 4

nephron pathway

Answer 4

afferent arteriole -> glomerulus -> glomeruler capsule -> proximal convoluted tubule -> nephron loop -> distal convoluted tubule -> collecting tubule -> collecting duct
