Answer:
c: cohesion
Explanation:
This cohesive relationship between the systems is known as pulmonary circulation. It helps the circulatory system in pumping the blood from the feet to the heart.
Passive transport<span> is a movement of </span>biochemicals<span> and other </span>atomic<span> or </span>molecular<span> substances across </span>cell membranes through <span>concentration gradients</span><span> without need of </span>energy<span> input. Unlike </span>active transport<span>, it does not require an input of cellular energy because it is instead driven by the tendency of the system to grow in </span>entropy<span>. The rate of passive transport depends on the </span>permeability<span> of the cell membrane, which, in turn, depends on the organization and characteristics of the membrane </span>lipids<span> and </span>proteins<span>. The four main kinds of passive transport are simple </span>diffusion<span>, </span>facilitated diffusion<span>, </span>filtration<span>, and </span>osmosis.

The major components of these fluids include water and solutes. The solute is mostly comprised of electrolytes: inorganic compounds that dissociate into ions. Electrolytes include cations (positively charged atoms – sodium, potassium, calcium, magnesium, carbonate) and anions (negatively charged atoms – chloride, sulphide, phosphate, bicarbonate).
