cooperation of multiple organ systems, including the endocrine and
nervous system

What is interstitial space? - 🧠 ANSWER ✔✔space/fluid in BETWEEN cells
How do different types of molecules (water, glucose, oxygen, sodium,
chloride) cross cell membranes and travel between different organs? - 🧠
ANSWER ✔✔Cell membrane is semipermeable to water. Oxygen move
across cell membranes simple diffusion, a process that requires no energy
input and is driven by differences in concentration on either side of the cell
membrane. Food is broken up through digestion and diffuse into the blood
through microvilli in the intestinal wall.
How is water regulated in your body? - 🧠 ANSWER ✔✔Homeostasis
What is osmosis and what does it have to do with water balance? - 🧠
ANSWER ✔✔The diffusion of water to create an equilibrium with salt.
