Excerpt

INTRODUCTION

- Overall, the excretory system plays key physiological role in the body.

- Of great physiological significance are the kidneys.

- Therefore, the objective of this presentation is to present an overview of the impact of stress on kidney functions.

Kidney Structure

- The kidney is a bean-shaped structure, and it comprises of different regions which perform different functions.

The main parts of the kidney are:

- Renal capsule- protects the kidney by enclosing it.

- Renal cortex – this is the reddish-colored outer part of the kidney. It holds the functional structures; the glomeruli, Bowman’s capsules, distal and proximal convoluted tubules, and blood vessels.

- Renal medulla – this is the interior portion of the kidney. It holds the renal pyramids.

- Renal pelvis – funnel-shaped cavity where urine drains from kidney nephrons (Fosbery 2004).

- Renal artery – supplies the kidney with oxygenated blood.

- Renal vein – carries deoxygenated blood from the kidney.

- Kidney nephron – kidney’s functional unit. It is estimated that each kidney comprises of a million nephrons.

- Collecting duct – drains the nephron.

- Ureter – conveys urine to the urinary bladder. (Rieg & Kohan 2014)

Function of Kidneys

Therefore, kidneys, the principal excretory organs carry out an array of functions.

- They are involved in the maintenance of the body’s homeostasis.

- Some of the main homeostatic functions that are performed by the kidneys include;-

- Regulates acid levels (acid-base balance)

- Regulates blood pressure (ions and water balance) (Bouby & Fernandes 2003)

- Maintains water balance

- Excretes wastes by filtering of toxins from blood

- Regulates red blood cells
