Question

multiple choice question
blood pressure generated by the ventricular contraction provides the force for ______ in capillaries.
filtration
active transport
diffusion
osmosis

Explanation:

Blood pressure from ventricular contraction forces fluid and small - solutes out of capillaries, which is filtration. Active transport requires energy and is not driven by blood pressure. Diffusion is the movement of substances from high to low concentration without pressure as the main driving force. Osmosis is the movement of water across a semi - permeable membrane due to solute concentration differences, not directly by blood pressure.

Answer:

filtration
