Flashcards in Chapter 7 & 8: Homeostasis Deck (86)
Tubes that conduct urine from the kidneys to the bladder.
Tube that carries urine from the bladder to the exterior of the body.
The outer layer of the kidney
The area inside of the cortex.
the area where the kidney joins the ureter.
Functional Units of the kidneys
Small branches that carry blood to the glomerulus.
High- Pressure capillary bed that is the site of filtration.
Small branches that carry blood away from the glomerulus to a capillary net.
A network of small blood vessels that surround the nephron.
Cuplike structure that surrounds the glomerulus.
Section of the nephron joining the Bowman's capsule with the loop of Henle
Loop of Henle
Carries filtrate from the proximal tubule to the distal tubule.
Conducts urine from the loop of Henle to the collecting duct.
Tube that carries urine from nephrons to the pelvis of a kidney.
The process by which blood or body fluids pass through a selectively permeable membrane.
Transfer of glomerular filtrate from the nephron back into the capillaries.
Movements of materials, such as ammonia and some drugs, from the blood back into the distal tubule.
The maximum amount of material that can be moved across the nephron.
The fluid that surrounds the body cells
Antidiuretic hormone (ADH)
Causes the kidneys to increase water reabsorption.
Specialized nerve cells in the hypothalamus that detect changes in the osmotic pressure of the blood and surrounding extracellular fluids (ECF).
The process by which a constant internal environment is maintained despite changes in the external environment.
A condition that remains stable within fluctuating limits.
The process by which a mechanism is activated to restore conditions to their original state.
Process by which a small effect is amplified.
Maintenance of body temperature within a range that enables cells to function efficiently.
Region of the vertebrate's brain responsible for coordinating many nerve and hormone functions.
Removal of an amino group from an organic compound.
