As everyone knows, hobbits are good to have along on an adventure. On any quest, a brave hobbit must keep his hairy feet well supplied with oxygenated blood or risk running out of gas long before he reaches the Lonely Mountain. Imagine that you are a freshly oxygenated erythrocyte in Bilbo Baggins' heart, and that you must set out on a great journey to supply the hobbit's right hallux (big toe) with oxygen. It is a long journey, so fortunately you have a map (below, left), but unfortunately the map is labeled with Elvish runes you cannot read. Once you deliver the oxygen and pick up the carbon dioxide at the Great Toe, you may take either a deep (dark) or a superficial (light) return route (below right). Using the table below, provide the most direct path to get There (arteries) and Back Again (veins). Assume that Hobbits have the same arteries and veins as Humans. For the return trip provide both the Deep and Superficial routes. In each case, there may be some places where two paths take you to the same place and you must choose one (some paths have more steps than others), but be sure to show a direct route (WARNING: Do Not Wander All Over Middle Earth or All Shall Be Lost!). At the outset of your journey, assume you have just left the Great Muscular Chamber of the Heart. While the Great Arterial Roadway may twist and turn, it remains the same, so you should name it only once. On your return, HOBBIT finish your journey by indicating the chamber where you first arrive back at the heart.

As everyone knows, hobbits are good to have along on an adventure. On any quest, a brave hobbit must keep
his hairy feet well supplied with oxygenated blood or risk running out of gas long before he reaches the Lonely
Mountain. Imagine that you are a freshly oxygenated erythrocyte in Bilbo Baggins' heart, and that you must set
out on a great journey to supply the hobbit's right hallux (big toe) with oxygen. It is a long journey, so fortunately
you have a map (below, left), but unfortunately the map is labeled with Elvish runes you cannot read. Once
you deliver the oxygen and pick up the carbon dioxide at the Great Toe, you may take either a deep (dark) or a
superficial (light) return route (below right). Using the table below, provide the most direct path to get There
(arteries) and Back Again (veins). Assume that Hobbits have the same arteries and veins as Humans. For the
return trip provide both the Deep and Superficial routes. In each case, there may be some places where two
paths take you to the same place and you must choose one (some paths have more steps than others), but be
sure to show a direct route (WARNING: Do Not Wander All Over Middle Earth or All Shall Be Lost!). At the
outset of your journey, assume you have just left the Great Muscular Chamber of the Heart. While the Great
Arterial Roadway may twist and turn, it remains the same, so you should name it only once. On your return,
finish your journey by indicating the chamber where you first arrive back at the heart.
