explain the functional correlation of circulatory system with respiratory,digestive and excretory system answer the following?
Answers
Circulatory system and Respiratory system relationship: You always inhale huge amount of Oxygen gas by your respiratory system. These O2 gas enters into blood through the blood capillaries in Alveoli of Lungs. Then Oxygen bound to Central Fe atom of Hemoglobin. Blood carries hemoglobin with O2 to body cells to supply metabolic fuel(Oxygen). O2 causes oxidation of sugar molecules in Mitochondria and produces ATP molecules that stores energy for biochemical events in cell. Blood contains water that is vaporized through Lungs. The metabolic waste product CO2 released into blood and bound to Hemoglobin and release through lungs.
Circulatory system and Digestive system correlation: You always eat different foods. Generally the foods contain Protein, Carbohydrates, Fats, Vitamins or may be any Drug. When you consume foods, the ingredients of food become separated and broken down into smaller molecules by digestive enzymes. Proteins broken down into Amino acids, Polysaccharides broken down into Monosaccharides and Disaccharides, Fats broken down into Glycerol and Fatty acids. But these Monosaccharides, Disaccharides, Amino acids, Fatty acids, Vitamins, Glycerol,water, Cholesterol and Drugs directly enters into blood stream through Villus(Network of blood capillaries) of digestive system. Then dissolve into Blood plasma. Blood transport these molecules into body cells.
Correlation with Excretory system: Blood Contains huge amount of water, metabolic waste products those are unnecessary or harmful for our body. When blood enters into Kidney through Renal Blood vessels, Nephrons extract water and other metabolic waste products from blood. These products transported to Urinary bladder and then excreted. Blood water and waste products also released through Sweat in skin.
