Unless fertilization occurs, the corpus luteum becomes scar tissue, which is known as the
A. Corona radiata
Corona radiata: The corona radiata is a layer of follicular (granulosa) cells that surround the oocyte -not scar tissue from a regressed corpus luteum.
B. Zona pellucida
Zona pellucida: The zona pellucida is a glycoprotein layer surrounding the oocyte important for fertilization, not scar tissue.
C. Internal os
Internal os: The internal os is the internal opening of the cervix into the uterus, unrelated to the corpus luteum.
D. Corpus albicans
Corpus albicans: The corpus albicans is the fibrous scar tissue that the corpus luteum becomes if fertilization does not occur .

The labia minora and labia majora are parts of which aspect of the female anatomy?
A. Uterus
Uterus: The uterus is an internal reproductive organ (the womb) and does not include the labia.
B. Fallopian tube
Fallopian tube: Fallopian (uterine) tubes are internal conduits for the oocyte; they are not the labia.
C. Vulva
Vulva: The vulva is the external female genitalia and includes the labia majora and labia minora .
D. Ovary
Ovary: The ovaries are internal gonads that produce oocytes and hormones; they are not the labia.

Which process involves the movement of oxygen from the blood into body cells and the exchange of carbon dioxide from cells into the blood?
A. Cellular metabolism
Cellular metabolism: Cellular metabolism refers to the chemical reactions inside cells that use O₂ and produce CO₂, but it does not describe the movement of gases between blood and cells.
B. Alveolar ventilation
Alveolar ventilation: Alveolar ventilation is the movement of air into and out of the alveoli (airways → lungs), not the exchange between blood and body cells.
C. External respiration
External respiration: External respiration is gas exchange between the alveoli and pulmonary capillaries (air and blood in the lungs), not between blood and tissues.
D. Internal respiration
Internal respiration: Internal respiration is the exchange of O₂ from the blood into body cells and CO₂ from the cells into the blood .

The pancreas functions as both an endocrine and exocrine gland. Which of the following accurately describes its dual role?
A. The exocrine function involves hormone release, while the endocrine function involves the secretion of buffers and enzymes.
The exocrine function involves hormone release, while the endocrine function involves the secretion of buffers and enzymes.: this reverses the roles; exocrine does enzymes/buffers, endocrine does hormones.
B. The endocrine function involves the secretion of digestive enzymes, while the exocrine function involves hormone release.
The endocrine function involves the secretion of digestive enzymes, while the exocrine function involves hormone release.: reversed roles.
C. The exocrine function involves the release of insulin and glucagon, while the endocrine function involves hormone release.
The exocrine function involves the release of insulin and glucagon, while the endocrine function involves hormone release.: insulin and glucagon are endocrine products, not exocrine.
D. The endocrine function involves the release of insulin and glucagon, while the exocrine function involves the secretion of digestive enzymes and buffers.
The endocrine function involves the release of insulin and glucagon, while the exocrine function involves the secretion of digestive enzymes and buffers.: the pancreas’ islet cells secrete insulin/glucagon (endocrine) and acinar/bicarbonate secretions go to the duodenum (exocrine).
