  • STUDENTS ARE RESPONSIBLE FOR STUDYING THEIR MANUAL AND FOR ALL THE MATERIAL COVERED DURING THE LABORATORY PERIOD, AS PER THE COURSE SYLLABUS.


This is a study guide not an all inclusive review

Lab # 9

Urinary System


This is a study guide not an all inclusive review

Functions of the Urinary System

1- Regulates blood composition and blood pressure, as well as body fluid composition and volume

2- Regulates blood pressure by releasing rennin, which activates the rennin-angiotensin mechanism that raises the blood pressure

3- Regulates some metabolic reactions by converting vitamin D to its active form

4- Releases erythropoietin, which increases production of red blood cells

5- Helps to regulate blood pH by controlling the loss of hydrogen and bicarbonate ions in the urine

6- Helps to regulate calcium ion levels by producing calcitriol
