In SIADH
This excess ADH leads to increased water reabsorption in the kidneys, (reducing / increasing) the amount of water excreted in the urine.
As a result, the urine becomes ( diluted / concentrated) with a(lower / higher) osmolality, while the bloodstream becomes diluted.
This imbalance contributes to the characteristic features of SIADH, including low sodium levels in the blood (hyponatremia) and concentrated urine despite an overall excess of body water.

Colloid Osmotic Pressure (COP), also known as oncotic pressure, is primarily exerted by proteins (such as ______) in the blood plasma.
. Changes in colloic pressure can contribute to several health problems:
Name (3)
Albumin
Edema:
Reduced colloid osmotic pressure can lead to the movement of fluid from blood vessels into the surrounding tissues, causing edema (swelling). This is commonly seen in conditions with low plasma protein levels, such as liver disease or malnutrition.
Hypovolemia:
Low COP can contribute to decreased blood volume (hypovolemia), resulting in symptoms such as dizziness, low blood pressure, and poor tissue perfusion.
Ascites:
In liver cirrhosis or other conditions causing liver dysfunction, low COP can contribute to the accumulation of fluid in the abdominal cavity, leading to ascites.

Hydrostatic pressure in capillaries is essential for the movement of fluids between blood vessels and tissues.
