We all have teeth quite sharp and strong, With which to chew our food, And in the mouth are glands and glands-- Yes, quite a numerous brood.
These glands pour out saliva, free, To moisten what we eat And then a trap-door at the throat Performs a wondrous feat
In guiding all the food along Into the Esophagus, And thence to stomach through a pass Called Cardiac Orifice.
And here 'tis mixed with Gastric Juice, And into chyme is churned Then through the gateway, Pylorus, As wiser ones have learned.
{146}
'Tis in the Duodenum now, Where it is mixed with Bile, And with the Pancreatic juice, Which changes it to Chyle.
This Chyle flows on, and all that's fit For nourishment and growth, Is taken up by Lacteals, Or "tubes with many a mouth."
These lead to the Thoracic Duct, Which holds a spoonful large, And from this Duct a pipe proceeds Through which it may discharge.
Into the great Sub-clavian vein, Which to the Heart doth lead, Whence it is sent into the Lungs, And into good blood made.
Then back into the Heart it flows, The muscles there contract, And pump it into Arteries, Which wind to every part.
We'd like to tell about the Bones, The Ribs and Vertebras, The Clavicle, or Collar-bone, Breast-bone, and Scapulae;
{147}
Of hinge, and ball-and-socket joints; Of muscles, tendons, skin, Of lungs and veins and arteries, Of nerves and heart and brain.
But, Ah! we should your patience tire, Were we the whole to tell, So, waiting till another time, We bid you now, farewell.
