Which two hormones are released by the adrenal medulla during a fight or flight response?
Insulin and glucagon
Dehydroepiandrosterone and estradiol
Ghrelin and kisspeptin
Epinephrine and norepinephrine
The Correct Answer is D
a. Insulin and glucagon: These hormones are produced by the pancreas and regulate blood glucose levels, not involved in the fight or flight response.
b. Dehydroepiandrosterone and estradiol: These are adrenal and gonadal hormones involved in sexual function and other roles, but not in the immediate stress response.
c. Ghrelin and kisspeptin: Ghrelin is involved in hunger signaling, and kisspeptin in reproductive hormone signaling, neither are involved in the stress response.
d. Epinephrine and norepinephrine: These are the primary hormones released by the adrenal medulla in response to stress, preparing the body for a fight or flight response by increasing heart rate, blood pressure, and blood glucose levels.

Correct Answer is C
Explanation
a. Kidneys: Kidney dysfunction can affect waste elimination and fluid balance but does not typically cause yellow sclera.
b. Appendix: The appendix is involved in the immune response and gut flora regulation but not in causing yellow sclera.
c. Liver: Liver dysfunction can lead to jaundice, where bilirubin accumulates in the blood and tissues, causing yellowing of the skin and sclera.
d. Spleen: The spleen is involved in blood filtration and immune response but does not directly cause yellow sclera
Correct Answer is D
Explanation
a. Decreased blood pressure due to increased blood viscosity: Increased viscosity makes blood flow more difficult, raising blood pressure, not lowering it.
b. Increased blood pressure due to decreased blood viscosity: Decreased viscosity would make blood flow easier, potentially lowering blood pressure, not raising it.
c. Decreased blood pressure due to decreased blood viscosity: Same error in reasoning as b.
d. Increased blood pressure due to increased blood viscosity: Red blood cells are the main components of blood that affect its viscosity (thickness). An increased concentration of red blood cells (erythrocytosis) makes the blood more viscous. Thicker blood increases resistance to flow within blood vessels, making the heart work harder to pump blood, which can lead to increased blood pressure.
