Identify the phases of the uterine cycle. (Select all that apply)
Secretory phase
Proliferative phase
Ovulatory phase
Menses
Luteal phase
Correct Answer : A,B,D
A. Secretory phase: The secretory phase is a uterine (endometrial) phase that follows ovulation when the endometrium is prepared for implantation by progesterone-driven secretions
B. Proliferative phase: The proliferative phase is the pre-ovulatory uterine phase in which the endometrium rebuilds under the influence of estrogen.
C. Ovulatory phase: “Ovulatory” refers to ovulation and is classically part of the ovarian cycle (the moment of egg release), not listed as a primary uterine cycle phase.
D. Menses: Menses (menstrual phase) is the shedding of the functional layer of the endometrium and is a primary uterine cycle phase.
E. Luteal phase: The luteal phase is an ovarian cycle phase (post-ovulation, corpus luteum activity). Although it corresponds in time to the uterine secretory phase, “luteal” names the ovarian, not uterine, phase.

Correct Answer is C
Explanation
A. Expiratory reserve volume: Expiratory reserve volume is the additional air that can be forcefully exhaled after a normal exhalation, not the maximum after a maximal inhalation.
B. Inspiratory capacity: Inspiratory capacity is the maximum amount of air that can be inhaled after a normal exhalation (tidal volume + inspiratory reserve), not the total that can be expelled after maximum inspiration.
C. Vital capacity: Vital capacity is the maximum volume of air that can be expelled from the lungs after a maximum inspiration (inspiratory reserve + tidal + expiratory reserve) .
D. Tidal volume: Tidal volume is the volume of a normal, resting breath and is far less than the maximum expelled volume.
Correct Answer is B
Explanation
A. Chief cells: Chief (zymogenic) cells secrete pepsinogen (precursor to pepsin) and some gastric lipase -not HCl or intrinsic factor.
B. Parietal cells: Parietal cells (oxyntic cells) secrete hydrochloric acid (HCl) and intrinsic factor (necessary for B12 absorption).
C. Mucous neck cells: Mucous neck cells produce mucus (and some protective secretions) to protect the stomach lining -not HCl/intrinsic factor.
D. Enteroendocrine cells: Enteroendocrine cells release hormones (e.g., gastrin, somatostatin) that regulate digestion -do not secrete HCl or intrinsic factor directly.
