WGU D313 ASSESSMENT PRACTICE
SOLUTION QUESTIONS AND SOLUTIONS
2026 GRADED A+.
◍ Which structure in the following image maintains equal air
pressure in the lung? Answer: alveolar pores
◍ Which cell type removes debris and pathogens from the alveolar
wall Answer: alveolar macrophages
◍ What leads to carbaminohemoglobin formation? Answer: CO2 +
Hb
◍ What is the role off the diaphragm during normal breathing?
Answer: During inhalation it contracts and flattens
◍ According to Boyle's law, what is the relation between pressure and
volume? Answer: When volume increases, pressure decreases at a
constant temperature.
◍ function of the aortic body? Answer: It monitors the partial
pressure of carbon dioxide, oxygen, and pH in the blood.
◍ function of arteries? Answer: They carry blood away from the
heart.
, ◍ How do temperature and pH affect hemoglobin oxygen saturation?
Answer: Higher temperature and lower pH promote the dissociation
of hemoglobin and oxygen.
◍ Which layer in the stomach, as shown in the following image,
secretes mucus and is called the mucus membrane? Answer: mucosa
◍ What is the sequence of the digestive processes? Answer:
Ingestion, digestion, absorption, defecation
◍ Where does intrinsic factor production occur Answer: parital cell
◍ Which structure in the following image stores feces prior to
defecation? Answer: rectum
◍ Which structure in the following image stores and concentrates
bile? Answer: gall bladder
◍ What is the order of the parts of the intestine, shown in the
following image, from shortest to longest? Answer: duodenum,
jejunum, and illeum
◍ What is the substrate of salivary amylase? Answer: Polysaccharides
