Question

What is the difference between ADH and blood pressure?.

Answer 1

Anti diuretic hormone (ADH)

• Anti diuretic hormone (ADH) is a peptide hormone synthesized by pituitary gland , which help in preventing dilute urine.
• It is synthesized in hypothalamus and secreted by posterior pituitary gland.
• It is released in response to hypertonicity of blood.It increases blood pressure through vasoconstriction.
• ADH make DCT and collecting tubule more permeable to water, hence directly increases water reabsorption.
• ADH is also known as vasopressin.

Blood pressure

• It is the pressure of circulating blood on the walls of blood vessel.
• Pressure occur due to pumping of blood from the heart through circulatory system.
• There are two type of blood pressure , they are systolic blood pressure( first value) and diastolic blood pressure (second). Eg : blood pressure is 120/80 mmHg.
• Ideal blood pressure is considered to be between 90/60mmHg and 120/80mmHg
• High blood pressure is considered to be 140/90mmHg or higher
• Low blood pressure is considered to be 90/60mmHg or lower
• High blood pressure is due unhealthy lifestyle.
• Angiotensin II is a powerful vasoconstricter , which increases glomerular filtration rate by increasing blood pressure.
