  2. Renal physiology - Wikipedia

    en.wikipedia.org/wiki/Renal_physiology

    The lungs contribute to acid-base homeostasis by regulating carbon dioxide (CO 2) concentration. The kidneys have two very important roles in maintaining the acid-base balance: to reabsorb and regenerate bicarbonate from urine, and to excrete hydrogen ions and fixed acids (anions of acids) into urine.

  3. Osmoregulation - Wikipedia

    en.wikipedia.org/wiki/Osmoregulation

    Osmoregulation is the active regulation of the osmotic pressure of an organism's body fluids, detected by osmoreceptors, to maintain the homeostasis of the organism's water content; that is, it maintains the fluid balance and the concentration of electrolytes (salts in solution which in this case is represented by body fluid) to keep the body fluids from becoming too diluted or concentrated.

  4. Mammalian kidney - Wikipedia

    en.wikipedia.org/wiki/Mammalian_kidney

    The kidneys can be unilobar (a single lobe represented by a single renal pyramid) or multilobar, [13] [14] unipapillary (a single or a common papilla), with several papillae or multipapillary, [14] [15] may be smooth-surfaced or lobulated. [1] [13] The multilobar kidneys can also be reniculate, which are found mainly in marine mammals. [16]

  5. Excretory system - Wikipedia

    en.wikipedia.org/wiki/Excretory_system

    Maintain pH and osmotic concentration of the extracellular fluid. Excrete toxic metabolic by-products such as urea, ammonia, and uric acid. The way the kidneys do this is with nephrons. There are over 1 million nephrons in each kidney; these nephrons act as filters inside the kidneys. The kidneys filter needed materials and waste.

  6. Kidney (vertebrates) - Wikipedia

    en.wikipedia.org/wiki/Kidney_(vertebrates)

    The kidneys are a pair of organs of the excretory system in vertebrates, which maintain the balance of water and electrolytes in the body (osmoregulation), filter the blood, remove metabolic waste products, and, in many vertebrates, also produce hormones (in particular, renin) and maintain blood pressure.

  7. Renal compensation - Wikipedia

    en.wikipedia.org/wiki/Renal_compensation

    Renal compensation is a mechanism by which the kidneys can regulate the plasma pH. It is slower than respiratory compensation, but has a greater ability to restore normal values. Kidneys maintain the acid-base balance through two mechanisms: (1) the secretion of H + ions into the urine (from the blood) and (2) the reabsorption of bicarbonate ...

    Spending quality time with dogs can have a positive impact on a person’s wellbeing. More specifically, new research shows that time spent interacting with canines reduces stress levels and ...

  9. Kidney - Wikipedia

    en.wikipedia.org/wiki/Kidney

    The two organ systems that help regulate the body's acid–base balance are the kidneys and lungs. Acid–base homeostasis is the maintenance of pH around a value of 7.4. The lungs are the part of respiratory system which helps to maintain acid–base homeostasis by regulating carbon dioxide (CO 2) concentration in the blood. The respiratory ...
