Contains almost everything from blood plasma but says NO to the big protein molecules (they're just too chunky to pass through the capillary walls).
Oxygen swap meet! 🌬
Cells are doing their fitness workouts (aerobic respiration) and burning up oxygen. So, they always need more. 🏋️
Just like how you might gasp for air after sprinting, cells "pull in" oxygen from tissue fluid because they have a lower concentration of it. This is called diffusion.
Sugar ride with glucose 🍬
Our cells are like us at a candy store. They need glucose for their energy needs.
There's a cool Uber-like service called sodium–glucose cotransporters which bring glucose into the cells.
Gym growing cells & amino acids 💪
Imagine cells are bodybuilders, needing amino acids (the building blocks of protein) to grow.
Cells don't just wait around! They actively "grab" these amino acids using a process called active transport.
