Blood delivers oxygen and nutrients to every part of the body and carries away carbon dioxide and other wastes from those same areas.

Quick Scoop: What Does Blood Deliver?

Think of blood as the body’s delivery and pickup service running nonstop through your blood vessels.

Main Deliveries to Every Part of the Body

  • Oxygen from the lungs to all your tissues and organs, so cells can make energy.
  • Nutrients from the digestive system, including:
    • Glucose (sugar for energy).
* Amino acids (building blocks for proteins).

* Fatty acids and other blood lipids (for energy and cell membranes).

* Vitamins and minerals.
  • Hormones from endocrine glands (like the thyroid, pancreas, adrenals) to target organs, acting as chemical messengers.
  • Heat, helping distribute warmth and regulate body temperature.
  • Immune cells (white blood cells) and antibodies to fight infections throughout the body.

What Blood Carries Away

At the same time, blood also “picks up” from every part of the body:

  • Carbon dioxide from cells to the lungs to be exhaled.
  • Waste products like urea, uric acid, creatinine, and toxins to the kidneys, liver, and intestines for removal from the body.

One-Line Answer
