Which of the choices below describes the pathway of cellular respiration (the complete oxidation of glucose)?

A. Tongue: The tongue assists in mechanical digestion and swallowing, making it an accessory organ.
B. Liver: The liver produces bile, aiding fat digestion, and is an accessory digestive organ.
C. Pancreas: The pancreas secretes digestive enzymes and bicarbonate, making it a key accessory organ.
D. Salivary glands: These produce saliva, initiating starch digestion-also accessory organs.
E. Spleen: The spleen is part of the lymphatic and immune system, not involved in digestion-not a digestive organ.

A. Extrinsic controls will reduce blood plasma volume while intrinsic controls will increase blood plasma volumes: This is too simplistic. Both can influence fluid volume, but their primary goals differ.
B. Intrinsic controls raise blood pressure while extrinsic controls lower blood pressure: Intrinsic controls maintain GFR, not blood pressure; extrinsic controls (like RAAS and sympathetic input) raise BP.
C. Extrinsic and intrinsic controls work in nearly opposite ways: They serve different purposes rather than being true opposites.
D. Extrinsic controls have the greatest effect on systemic blood pressure while intrinsic controls have a greater effect on GFR: Intrinsic (renal autoregulation) maintains a constant GFR; extrinsic controls (like sympathetic nervous system and RAAS) maintain systemic blood pressure, especially during stress or blood loss.
