“Briefly describe the importance of the interaction between the respiratory and cardiovascular systems in maintaining the body’s internal balance”
What is the respiratory system?
The respiratory system consists of the nose, pharynx, larynx, bronchi and lungs. Their function is to filter warm and moistened air and conduct it into the lungs. The respiratory system contributes to homeostasis (highly complex interactions to maintain balance.)( Wiki) by providing for the exchange of gases, - oxygen and carbon dioxide, - between the atmospheric air, blood and tissue cells.
.It also helps to adjust the Ph of body fluids. Your body cells continually use oxygen (O2) for the metabolic reactions that release energy from nutrient molecules. At the same time these reactions release carbon dioxide (CO2).
Because an excessive amount of co2 produces acidity that can be toxic to cells excess co2 must be eliminated quickly and efficiently.. ( Tortora & Derrickson 2006)
What is the cardiovascular system?
The heart is the primary organ of the cardiovascular system It is a beating muscle that continually pumps blood to the rest of the body. ( Tortora & Derrickson 2006) Oxygenated blood, which is pumped through the body via the arteries, supplies the body's tissues with oxygen that they need to live. Blood in the arteries is under high pressure; however, which could damage the tissue, so this oxygenated blood first needs to go to the capillaries, which are very small and low-pressure blood vessels that are responsible for supplying the oxygenated blood to the tissues. . Once the capillaries have delivered their oxygen, they also absorb excess carbon dioxide into the blood and then deliver it to the veins, which then supply the blood back to the heart. (Cloe , 2011)
The cardiovascular and respiratory systems co-operate to eliminate co2. The respiratory system provides for gas
