While running you breathe faster and harder and your heart rate increases. This illustrates that body systems
A
work together
B
work independently
C
all have the same function
D
have no connection one another
Explanation: 

Detailed explanation-1: -When you are exercising, your muscles need extra oxygen-some three times as much as resting muscles. This need means that your heart starts pumping faster, which makes for a quicker pulse. Meanwhile, your lungs are also taking in more air, hence the harder breathing.

Detailed explanation-2: -It’s normal for your breath and heart rate to increase when you’re running or doing a lot of exercise. Activities that increase your heart and breathing rate may be called cardiovascular exercise. The increased rate helps your body to meet the demands of your exercise.

Detailed explanation-3: -The body uses different systems to help it run. The respiratory system and the muscular system are all used when running. The heart is a muscle that pumps blood through the circulatory system to deliver oxygen and nutrients to tissues. It also helps remove waste products from the body.

Detailed explanation-4: -Breathing rate increases to provide the body (exercising muscles) with oxygen at a higher rate. Heart rate increases to deliver the oxygen (and glucose) to the respiring muscles more efficiently. The heart, lungs and circulatory system working together make up the cardiovascular system.
