Answer: feed forward

Flashcard 3: _____ is calculated by Vant Hoffs law.

Flashcard 4: Nernst potential is the _____cellular potential required to prevent the outward or inward movement of an ion

Answer: intra

Flashcard 5: The value of normal tissue oncotic pressure is _____ mmHg

Answer: 8

Extra: According to Guyton and Hall Textbook of Medical Physiology, the average interstitial (tissue) colloid osmotic (oncotic) pressure is approximately **8 mmHg**. **Starling Forces Summary (Systemic):** * **Capillary Hydrostatic Pressure ($P_c$):** ~17.3 mmHg (mean) * **Interstitial Hydrostatic Pressure ($P_{if}$):** -3 mmHg * **Plasma Colloid Osmotic Pressure ($\pi_p$):** 28 mmHg * **Interstitial Colloid Osmotic Pressure ($\pi_{if}$):** 8 mmHg Net filtration pressure is approximately 0.3 mmHg, which is returned to circulation via the lymphatics.
