Dear friends, I would like to bring your attention to the importance of understanding disorders of the excretory system. Let's educate ourselves and promote awareness for better health. #ExcretorySystemDisorders #HealthEducation

2. ➢ Accumulation of urea in blood due to malfunction of
kidney.
➢ It may lead to kidney failure (renal failure).
➢ In such case, urea can be removed by a process
called haemodialysis.
UREMIA

3. ➢ It is a process of removal of urea from blood.
➢ The dialyzing unit (artificial kidney) contains a coiled
cellophane tube surrounded by dialyzing fluid
➢ It has same composition of plasma except the
nitrogenous wastes.
➢ Blood drained from a convenient artery is pumped
into dialyzing unit after adding an anticoagulant like
heparin.
HAEMODIALYSIS

4. ➢ The porous cellophane membrane of the tube allows
the passage of molecules based on concentration
gradient
➢ As nitrogenous wastes are absent in dialyzing fluid,
these substances freely move out, thereby clearing
the blood.
➢ The cleared blood is pumped back to the body
through a vein after adding anti-heparin to it.
HAEMODIALYSIS

5. ➢ It is the ultimate method in the correction of acute
renal failures.
➢ A functioning kidney is taken from a donor.
➢ It is better to receive kidney from a close relative to
minimize chances of rejection by immune system of
host.
KIDNEY TRANSPLANTATION

6. ➢ Renal calculi is also known as nephrolithiasis or
simply kidney stone.
➢ Stone or insoluble mass of crystallised salts
(oxalates, etc.) formed within the kidney.
➢ Improper diet, excess body weight, and certain
medications are some of the reasons behind this.
RENAL CALCULI

7. ➢ Glomerulonephritis is the inflammation of glomeruli.
➢ This results in proteins and RBCs passing into the
filtrate
➢ It is caused due to injury to the kidney, bacterial
toxins, drug reactions, HIV infections, hepatitis B
and hepatitis C, high blood pressure, high diabetes,
etc.
