Progesterone is produced by the ovaries after ovulation. What is its main function?
A. Maintaining the uterine lining for potential pregnancy
Maintaining the uterine lining for potential pregnancy: Progesterone is produced by the corpus luteum after ovulation and prepares/maintains the endometrium for implantation and early pregnancy.
B. Promoting sperm production
Promoting sperm production: Sperm production is a male function driven by FSH and testosterone; progesterone does not promote spermatogenesis.
C. Inducing uterine contractions
Inducing uterine contractions: Progesterone actually inhibits uterine contractions to help maintain pregnancy; oxytocin and prostaglandins promote contractions.
D. Enhancing follicle development
Enhancing follicle development: Follicle development is primarily stimulated by FSH and estrogen during the follicular phase; progesterone is dominant after ovulation and does not enhance follicle development.

What term refers to the temporary cessation of breathing?
A. Apnea
Apnea: Apnea is the temporary cessation (absence) of breathing.
B. Dyspnea
Dyspnea: Dyspnea means difficult or labored breathing (shortness of breath), not cessation.
C. Hyperpnea
Hyperpnea: Hyperpnea refers to increased depth and/or rate of breathing (e.g., during exercise), not a pause.
D. Eupnea
Eupnea: Eupnea is normal, unlabored breathing; the opposite of cessation

Which of the following sequences correctly represents the order air passes through during inhalation in the respiratory system?
A. Nasal cavity, pharynx, larynx, trachea, bronchi, bronchioles, alveoli
Nasal cavity, pharynx, larynx, trachea, bronchi, bronchioles, alveoli: This correctly lists the anatomical pathway air follows from entry to the gas-exchange sites.
B. Nasal cavity, pharynx, trachea, larynx, bronchi, bronchioles, alveoli
Nasal cavity, pharynx, trachea, larynx, bronchi, bronchioles, alveoli: This places the trachea before the larynx (incorrect order); the larynx is between the pharynx and trachea.
C. Nasal cavity, pharynx, larynx, trachea, bronchioles, bronchi, alveoli
Nasal cavity, pharynx, larynx, trachea, bronchioles, bronchi, alveoli: This incorrectly reverses bronchioles and bronchi -bronchi branch into bronchioles, not the other way around.
D. Nasal cavity, larynx, pharynx, trachea, bronchi, bronchioles, alveoli
Nasal cavity, larynx, pharynx, trachea, bronchi, bronchioles, alveoli: This places the larynx before the pharynx (incorrect); air passes through the pharynx first then the larynx.

The capillaries and lymphatics that transport nutrients absorbed across the wall of the GI organs lie in the
A. Muscularis
Muscularis: The muscularis is the smooth muscle layer responsible for peristalsis/segmentation; it contains muscle, not the primary capillary/lymphatic beds for nutrient absorption.
B. Mucosal epithelium
Mucosal epithelium: The epithelial layer faces the lumen and absorbs nutrients at the cell surface, but the transport capillaries/lymphatics lie deeper than the epithelium.
C. Serosa
Serosa: The serosa is the outer connective tissue covering of the gut -it does not contain the nutrient capillaries and lacteals.
D. Lamina propria
Lamina propria: The lamina propria (a connective tissue layer within the mucosa) contains blood capillaries and lymphatic lacteals that transport absorbed nutrients.
