Efffects of Physical Activities on Excretory System
What are the functions ofthe Excretory System?
Get rid of wastes Eliminates useless by-products
excreted from cells Eradicates harmful chemical
build-ups Maintains a steady, balanced
chemical concentration
Parts of the Excretory System Only the organs specifically for the excretion process are considered a part of the excretory system.Urinary System
Respiratory SystemIntegumentary SystemLiver Large Intestine
Urinary System as a part of Excretory System
Urinary Bladder
Urethra
Ureter
BLOOD
Blood first passes through the renal artery
To the capillary formation called a glomerulus and is collected in the Bowman's capsule, which filters the blood from its contents—primarily wastes.This is the stage of Filtration.
WASTEWastes pass through the tubules to the pelvis of the kidney as urine. This is the stage of Reabsorption.
Urine passes through the ureters, stored in urinary bladder, then expelled through the urethra.
Respiratory System as a part of Excretory System
ORGANS OF THE BODY
O2 O2O2
OXYGEN IS INHALED
Carbon dioxide are exhaled
CO2CO2CO2
Diffusing gaseous wastes, such as carbon dioxide, from the body organs as a normal part of respiration. LUNG
S
Integumentary System as a part of Excretory System.
The skin contains sweat gland which produces sweat.. The salt helps evaporate the water, cooling off the skin.Sweat is excreted through sweat glands.
Large Intestine as a part of Excretory System
A watery residue of indigestible food and digestive juices remains unabsorbed. This residue leaves the ileum of the small intestine and moves by peristalsis into the large intestine, where it spends 12 to 24 hours.
The large intestine moves its remaining contents toward the rectum, which stores solid wastes, until elimination.
Liver as a part of Excretory System
Produce bile, a yellowish-brown liquid.
These are produced within the lobules.
Bile leaves the liver through a network of ducts and is transported to the gallbladder, which concentrates the bile.
Then, releases it into the small intestine. It contains salts necessary for the digestion of lipids, or fats.
How does Physical Activities
affects each part of
Excretory Systems?
How do Physical Activities affects the Excretory- Urinary System?
Urinary Bladder
Urethra
Ureter
BLOODWASTE
BLOOD
There is a great reduction in renal blood flow. This drop in renal blood flow can be explained by the diversion of blood to the working muscles and the brain.
Because of the decrease in blood flow, the amount of fluid filtered by the kidneys also is reduced resulting in decreased liquid waste production.
How do Physical Activities affects the Excretory- Respiratory System?
*When you do Physical Activities, much of the body's blood rushes to the muscles to help fuel the physical activity BLOOD*Then heart pumps increased volumes of blood.
BLOOD*This surging of blood often results in a need for more oxygen in the blood than is present, and thus the body's breathing rate increases.
O2
CO2
More blood carrying oxygen means increase in production of Carbon dioxide to be exhaled.
How does Physical Activities affects the Excretory- Integumentary System?The body must get rid of the heat produced by the physical activity, therefore heat is loss by evaporation of sweat.
There are more sweating in physical activities than not.
How does Physical Activities affects the Excretory- Large Intestine?Stimulates normal contractions in your intestines,proper digestion.
Reduces the symptoms of irritable bowel syndrome and other similar conditions.
Proper Elimination of Solid Wastes.
Promote regular bowel movements
How does Physical Activities affects the Excretory- Liver?
Aerobic Activities
Speeding up delivery of oxygen to vital body organs, such as the liver.
Well Liver producing good bile.
Weight training
Reduces body fat
Reduces job for biles.
