Blood flow through metarterioles maximises blood-tissue exchange. True / False

b) Choose the correct options to complete the sentence below:

When the metabolic activity of a tissue increases, the PCO2 increases decreases and the PO2 increases decreases , causing dilation constriction of the arteriole. This phenomenon is called active hyperemia reactive hyperemia arteriolar tone myogenic response extrinsic regulation .

Chemical pathways by which living things function, especially those that provide cellular energy, such as the transformation of energy from food into the energy of ATP. Metabolism also focuses on chemical pathways involving the synthesis of new biomolecules and the elimination of waste.

Please answer with explanation. Asap I will really upvote.
Select the true statements. Select all that apply. O Hydrostatic pressure of the interstitial fluid will pull fluid out of the capillary into the tissue at the venule end. O Osmotic pressure of the interstitial fluid will push fluid into the tissue at the arteriole end. O Osmotic pressure of the capillary will cause fluid to move back into the capillary near the venule. O Hydrostatic pressure of the capillary will force fluid out to the tissue at the arteriole end.
