How do the respiratory system and the cardiovascular systems work together?

Answer 1

The respiration and cardio vascular work together o make the body become alive. It does this by having 2 different system working in the body. The 2 are respiration and cardio vascular system. the respiration system bring the air from outside the body through the mouth or nasal cavity. Then goes down to the Pharynx which leads up to the Epiglottis which goes passed through the larynx which goes to the trachea which goes into the lungs. In the lungs, the air goes to the bronchi which brakes down into the bronchioles

which goes into the alveoli sack where the air takes out the oxygen from the air. This is also the connected point to the cardio vascular system which it gives it the oxygen it needs to complete its job. The blood is out side the alveoli sack in a capillary. The way the gas can go through the capillary walls is because the walls of it is one cell thick which allows things to pass through. The blood flows through the capillary which widens into a venues which widens into veins which goes to the heart. The heart pumps the blood around the body. It first pumps it to the arteries which goes smaller into a arterioles which goes into a capillary. The capillary gives the oxygen to the muscle and receives it's waste products e.g. oxygen. The deoxygenated blood goes through the capillary which widens into venues which then widens into a veins which leads to the heart and gets pump into a arteries which becomes into arterioles which goes back into a capillary which give the carbon dioxide to the alveoli sack which the alveoli sends away through the bronchioles

which widens into bronchi which trachea which then goes through the larynx which then goes pass the Epiglottis which then goes through the Pharynx which goes back out through the nasal cavity or mouth.

Answer 2

Long story short, you need oxygen to live. Think fresh oxygen = good. When the body uses oxygen (O2), the waste of the cellular reactions is carbon dioxide (CO2). Think of this gas as bad. When you breathe, think of it as in with the good gas (O2) and out with the bad (CO2).

Answer 3

The function that the Circulatory and Respiratory Systems do together is to gather oxygen and pump it to the trillions of cells of the human body.
