Blood vessels in the circulatory system transport blood away from and towards the heart. Arteries carry blood away from the heart as well as veins carry blood back to the heart.
The circulatory system transports oxygen, nutrients, as well as hormones to cells, and eliminates waste products, like carbondioxide.
Food is broken down into nutrients such as carbohydrates, fats, and proteins by the digestivesystem.

Answer:
oxidation
Explanation:
From the moment we perform body movements, there is a greater demand for oxygen. This is due to the need for oxidation of energetic substrates such as free fatty acids and circulating glucose. Thus, aerobic metabolism is potentially increased to supply the energy required by muscle contractions, whatever their intensity. From this we can say that breathing hard during exercise brings oxygen to the muscles, which helps the oxidation process release energy to fuel the workout.

The short answer is that velocity is the speed with a direction, while speed does not have a direction. Speed is a scalar quantity—it is the magnitude of the velocity. Speed is measured in units of distance divided by time (e.g., miles per hour, feet per second, meters per second, etc.).
