The osmotic gradient ____ as it moves deeper into the medulla?
Increases
How is the high osmolarity of the renal medulla is maintained?
Counter-current multiplication which occurs on the Vasa Recta helps maintain high osmolarity in the renal medulla Sodium Chloride (NaCl, or salt) is pumped out of the ascending limb of the loop of Henle. The result is that the renal medulla has a high salt concentration, and therefore a low water concentration.
What is the main factor that creates the high osmotic gradient between the cortex and medulla?
A high osmotic gradient between the cortex and the medulla is caused by the running, walking, or jumping of a human person. These simple actions cause the osmotic gradient to rise significantly.
Where is osmolarity greatest in kidney?
Osmolarity is greatest in the innermost portion of the medulla near the renal pelvis due to the osmotic gradient. As one goes deeper into the renal medulla, the osmotic gradient increase. The osmolarity varies from 300 mOsm at the edge of the medulla to the innermost at approximately 1200-1400 mOsm. Think of the movie, Silence of the Lamb, when Anthony Hopkins eats that kidney, as he eat closer and closer to the kidney, it get salter. The medullary osmotic gradient is used for water reabsorption in the collecting duct, when ADH is present, thus increasing blood volume and result in increasing blood pressure.
What happens to the filtrate concentration of water as it descends the tubules?
As the filtrate goes down the hypertonic interstitum of the renal medulla, water leaves the filtrate into the interstitum. As such, the water concentration in the filtrate decreases.
What part of the brain stem includes the cardiac and vasomotor centers?
The Medulla Oblongata
What does the medulla look like?
The medulla.
Definition of the medulla?
The medulla oblongata is the part of the brain that controls autonomic functions. Some of the functions that it controls are digestion, breathing, heart function, and swallowing.
Respiratory control centers are located in the .?
medulla and pons
What is is the medulla of the kidney?
medulla is the husband of maducia
Is eating a lollipop cerebellum or the medulla?
