Study Question Eleven

• Q11. Discuss the different organ systems that the kidneys interact with to promote homeostasis.
• Urinary System

  • Kidneys are key organs in urinary system. Main function is to filter blood to remove waste products and excess substances, excreted as urine. Regulate volume and composition of urine, adjusting for water, ions, and pH to maintain homeostasis.
  • Key Functions:
  • Filtration of blood.
  • Reabsorption of water, glucose, ions, etc.
  • Secretion of waste products and excess ions into the urine.
• Cardiovascular System

  • Blood Pressure Regulation:
  • Kidneys regulate blood pressure through renin angiotensin aldosterone system (RAAS). When blood pressure drops, kidneys release renin, activates RAAS, leading to increased sodium reabsorption and water retention, increasing blood volume and blood pressure.
  • Electrolyte Balance:
  • Kidneys help maintain balance of sodium, potassium, calcium, etc, essential for cardiovascular function.
  • Erythropoiesis:
  • Kidneys produce erythropoietin in response to low oxygen, for production of red blood cells in bone marrow. Ensure oxygen is transported.
• Digestive System

  • Electrolyte Balance: Kidneys regulate levels of electrolytes in bloodstream, influenced by absorption of nutrients.
  • Vitamin D Activation: Kidneys convert vitamin D into active form, calcitriol, essential for calcium absorption in intestines.
  • Waste Removal: Kidneys filter metabolic waste products from bloodstream, and excess nutrients absorbed from food but no longer needed.
• Discuss the different organ systems that the kidneys interact with to promote homeostasis.

  The kidneys are connected to various systems throughout the body, some of which include the urinary system, cardiovascular system, and the digestive system. The kidneys are the key organ in the urinary system, as they function to filter blood to remove waste in the form of urine.
• Discuss the different orang systems that the kidneys interact with to promote homeostasis.

  The function of filtering blood assists in the cardiovascular system, they additionally increase blood volume and blood pressure if necessary. Additionally, the kidney assists in electrocyte balance and in producing erythropoietin in response to low oxygen which ultimately allows for the production of red blood cells, both of these functions further assist the cardiovascular system.
• Discuss the different organ systems that the kidneys interact with to promote homeostasis.

  The kidney's function of electrocyte balance also assists the digestive system. The kidneys also convert vitamin D into calcitriol which is essentially for calcium absorption within the intestines. And like in the urinary system, the kidney assists in waste removal for the digestive system.
