Traced from mouth to venous blood, one dietary triglyceride fills this SC115 Unit 3 digestion pathway diagram: labeled organs, enzymes, hormones and transport forms, with a written key. Searches like "sc 115 unit 3 assignment example", "sc115 unit 3 sample" and "sc115 unit 3 example" land here.
What a finished SC115 Unit 3 digestion pathway diagram looks like
The diagram runs top to bottom along a simplified digestive tract, with the triglyceride's changing form drawn at each station. Minor lipase activity is marked in the mouth and stomach. At the duodenum, two hormone boxes, CCK and secretin, point to the gallbladder and pancreas. Bile salts are shown breaking large droplets into small ones, and pancreatic lipase, with colipase, cutting each triglyceride into a monoglyceride and two free fatty acids. Micelles ferry those products to the enterocyte, where they are rebuilt and packed into chylomicrons. Arrows then leave through the lacteal, follow lymph to the thoracic duct and enter a large vein near the heart. A side branch shows short- and medium-chain fatty acids taking the portal route directly.
How a SC115 Unit 3 example is structured
Most samples pair one full-page diagram with a written key of roughly equal length. The diagram uses a consistent visual grammar: organs in one shape, enzymes in another, hormones in a third, and the nutrient's form at each step in bold, with a legend in the corner explaining the conventions. Numbered stations along the tract correspond to numbered paragraphs in the key, so the grader can move between the two. Each key paragraph states what enters that station, the agent acting on it, the product that leaves, and why the step is needed. A closing paragraph explains why fat, unlike glucose or amino acids, cannot simply dissolve in plasma and enter the portal circulation. Sources for each labeled fact are cited in the key rather than crowded onto the diagram itself.
One molecule, followed throughout
The diagram tracks a single triglyceride's form at every station, so the reader sees what it has become, not only where it is.
Hormones drawn as signals
CCK and secretin appear as arrows from the duodenum to the organs they prompt, which makes control of the process visible.
Emulsification kept apart from hydrolysis
Bile makes droplets smaller; lipase breaks ester bonds. The diagram gives each its own station, since the two are often merged.
Reassembly inside the enterocyte
The cell box shows products rebuilt into triglyceride and packaged, the step that explains why fat leaves the gut differently from sugars.
The lymphatic detour
Chylomicrons are shown entering the lacteal and reaching venous blood through the thoracic duct, with the portal shortcut for shorter chains drawn beside it.
Where marks go in SC115 Unit 3
The largest deductions go to diagrams that show where fat goes but not what it becomes, so arrows move an unchanged 'fat' from box to box. Bile is the most frequent factual error: drawn as an enzyme, or credited with breaking bonds it only exposes to lipase. Chylomicrons placed directly in the portal vein, or absorption shown in the stomach, lose accuracy points in most sections. Missing labels matter more here than in prose assignments because the diagram is the answer. A key that merely repeats the labels without explaining why each step is necessary earns partial credit. Visual clutter costs something too: unexplained colors, arrows that cross, or a legend that does not match the drawing. Uncited diagrams traced from a website draw a plagiarism query.

SC115 Unit 3 questions, answered
Why do so many sections pick fat for this diagram?
Because its path involves more distinct steps than carbohydrate or protein: emulsification, hydrolysis, micelle transport, re-esterification and the lymphatic route. Each step is a place to show understanding. If your section assigns protein or carbohydrate, the diagram is simpler, and the written key usually carries more of the explanation. Amino acids, for instance, pass straight into portal blood once absorbed, so the drawing ends sooner.
Can the diagram be hand drawn?
Many sections accept a neat hand drawing photographed clearly, and some prefer it. Slide or drawing software works equally well. Legibility and correct labels matter far more than polish, and a hand drawing with an accurate key usually outscores a polished graphic that misplaces one step of the pathway. Photograph in even light so that small labels stay readable.
How much should the written key say?
Enough that someone who could not see the diagram would still understand the pathway. For each numbered station, state what enters, what acts on it, what leaves, and why. Your rubric may set a length; if not, a few sentences per station is typical, with a citation attached to each factual claim.
