Blood Transportation: Essential Nutrients, Oxygen, CO2 & Hormones

Nutrients: Nutrients such as glucose, amino acids, and lipids are transported in the blood from the digestive system to the body's cells.

* Oxygen: Oxygen is transported in the blood from the lungs to the body's cells.

* Carbon Dioxide: Carbon dioxide is transported in the blood from the body's cells to the lungs.

* Hormones: Hormones are transported in the blood from endocrine glands to target cells throughout the body.

* Electrolytes: Electrolytes, such as sodium, potassium, and calcium, are transported in the blood to maintain fluid balance and regulate nerve and muscle function.
