In terms of blood, what does the term 'transportation' refer to?

The term 'transportation' in the context of blood refers to the crucial role it plays in carrying oxygen and nutrients to body cells. Blood is responsible for delivering essential gases, such as oxygen, from the lungs to the tissues throughout the body, ensuring that cells receive the necessary elements for metabolism and energy production. Additionally, blood transports nutrients absorbed from the digestive tract directly to the cells to support various cellular functions and maintain overall homeostasis. This dual function of oxygen and nutrient delivery is vital for sustaining life and promoting healthy bodily functions.
