BIOD 151 Final Exam 2025 From Portage Learning
Includes Accurate And Verified Questions Covering
Human Anatomy And Physiology. Topics Include
Body Systems Such As Cardiovascular, Respiratory,
Digestive, Nervous, Musculoskeletal, Urinary, And
Endocrine,As Well As Foundation Concepts.
Air and food pass in which of the following areas? - -<<answer>>--
oropharynx
Be able to label respiratory system - -<<answer>>--see image
From widest to narrowest, the branches of the bronchial tree are - -
<<answer>>--primary bronchi, secondary bronchi, tertiary bronchi,
bronchioles
Explain why someone who has hypergastrinemia (excessive secretion of
gastrin) might develop gastric/stomach ulcers. - -<<answer>>--Gastrin
stimulates the secretions of pepsinogens and hydrochloric acid. Excess
amounts would lead to erosion of the stomach lining.
,Be able to label digestive system - -<<answer>>--see image
Describe parietal and chief cells: name their location, secretion,
purpose - -<<answer>>--parietal cells: located in the wall of the stomach
body, secrete HCl acid, generating a pH of 1.3-3.5. The very acidic pH
kills much of the bacteria ingested along with food and it also stops the
activity of salivary amylase. This is also necessary to activate pepsin.
Chief cells secrete pepsinogen which is a preenzyme secreted by the
cief cells int he stomach. HCl acid converts an inactive pepsinogen into
an active enzyme pepsin which begins the breakdown of proteins
Be able to label skeletal system - -<<answer>>--see image
Be able to label carpals/metacarpals - -<<answer>>--see image
What is osteoporosis and what type of bone cell would the patient be
lacking? - -<<answer>>--1) it is a bone tissue disease. When bone tissue
degenerates faster than is replaced and the bones become weak. Brittle
bones cause pain 2) they have decreased osteoblasts that are
responsible for bone repair
When the extensor digitorum contracts, what actions occur? - -
<<answer>>--wrist extension, extension of digits 2-5
, Would you expect a male to have estrogen in their blood stream? - -
<<answer>>--yes, we all have sex hormones, just different ratios. Adrenal
glands are responsible for producing these
What hormone is responsible for depositing calcium into bone? - -
<<answer>>--calcitonin
What hormone is secreted by the beta cells of the pancreas? - -
<<answer>>--insulin
Explain how too much aldosterone could contribute to high BP - -
<<answer>>--Aldosterone's primary target is the kidney, where it
promotes renal absorption of sodium and renal excretion of potassium.
The blood sodium level is particularly important ot the maintenance of
BP. Too much sodium causes retention of fluid and increases BP
Be sure to know sensory organs of the skin - -<<answer>>--see image
What is catabolism v anabolism? - -<<answer>>--catabolism is breaking
down complex macromolecules, anabolism is building molecules from
simpler macromolecules
What are the steps of cellular respiration? - -<<answer>>--glycolysis -
glucose converts to pyruvate and atp; citric acid cycle - pyruvate
