📝 Quick Overview: Capillaries play a "leak and take-back" game with our blood plasma. This game involves releasing tissue fluid (a type of extracellular fluid) and later reuptaking it. This movement depends on blood pressure, and it's a constant process happening in our bodies.

Plasma - the watery mix of our blood 🚿

  • What is it? Plasma is like the soup of our blood, and blood cells are like the veggies floating in it.
  • What's in the soup?
    • Water (H2O) 🥤
    • Yummies like glucose (sugar) 🍬, amino acids (protein building blocks) 💪, and vitamins 🍊.
    • Mineral ions: Think of table salt breaking down into chloride and sodium.
    • Hormones (body's message carriers) 💌.
    • Plasma proteins.
    • Fat? Yep! But they roll around in special droplets called lipoproteins.

🛑 Fun Fact: Imagine a chocolate chip cookie. The cookie dough is the plasma, and the chocolate chips are the blood cells. Yum!

Capillary walls - the grand leakmasters 🔎

  • Adapted to let part of the blood plasma ooze out into spaces between our body cells. Like a sponge, it can squeeze out some water but retains the big stuff.
  • Most protein molecules act like "too-big-to-fit" guests and stay inside, but smaller substances enjoy the slide and go out!
