4. Excretory System
• The removal of metabolic & other
waste from the body is called
Excretion and …..
• The System which helps to remove
this waste from the body is known
as Excretory System .
• The Excretory system consists of
many organs in our body which
helps in the removal of waste
5. Main Excreting Organs
• Kidneys
• Lungs
• Skin
• Large Intestine.
• Liver – Dextoxification centre
- Factually speaking – Liver is not an excreting organ but it produces many
products which are excreted elsewhere
- Converts excess amino acids from protein digestion to urea ,which is filtered
by kidneys & excreted out in urine
- Toxins , drugs as well as alcohol are broken down in the liver and then carried
away to be excreted .
- Excretion also takes through Eyes ,Ears , Nose.
6. URINARY SYSTEM
Consists of….
• KIDNEYS– 2 bean shaped organs
- located at the backside of the abdomen just below the ribs
- right kidney is slightly lower because of the liver .
- kidneys take the waste from blood , filters it to produce the liquid urine which is
then excreted
• URETERS - 2 muscular tubes , around 35cm long, 1 each from the kidneys- carry
urine from the 2 kidneys to the Bladder
• URINARY BLADDER
- Muscular bag that holds / stores urine until it is excreted
- Has a capacity of around 500 ml.
- Made up of strong muscles &
- has a great number of folds which allow the bladder to expand
• URETHRA
- Tube through which urine passes out of the body
About 1.5 litres of urine excreted in a day.
7. FUNCTIONS OF KIDNEYS
• Renin formation – imp for BP control ,Sodium & water regulation
• To regulate the concentration of soluble substances
• To reabsorb what is needed & to excrete the rest as Urine .
• Thus Urine formation & excretion ( eliminating waste from body )
• To regulate Blood volume & BP
• Erythropoietin production – depends on level of Oxygen tension in
blood –stimulating the bone marrow to increase the production of
RBCs
• Production of active form of Vit D
• To control levels of Electrolytes ( Sodium , Potassium ,Chloride ) &
metabolites
• To regulate blood ph – acid- base balance.
• Overall to maintain homeostasis in body
8. YOGIC CORELATION
ASANAS…some examples ..
• Sarvangasana & such other asanas, by way of the posture…..
- affect kidneys in detection of Oxygen tension .
- This stimulates RBC production due Erythropoietin ( EPO) production
( As Erythropoietin production depends on Oxygen tension which affects RBC
production)
• Bhujangasan , Dhanurasan , Ardhamatsyendrasan etc..
- give massage to kidneys
- improves blood circulation around & within the kidneys
- increases the kidney functioning capacity & hence entire urinary system
• Halasan - useful in polyuria condition
9. PRANAYAMA
In abdominal breathing the diaphragm moves down during
Inspiration.
Kidneys also go down by 2.5 cm leading to
- toning of the kidneys
- good blood circulation
- improved functioning of kidneys
• ADH – Antidiuretic hormone is secreted through the Pituitary
which is controlled by the hypothalaums.
• All yogic practices have a positive effect on the hypothalamus .
- helps in water regulation
- balance of salts &
- maintains homeostasis through improved kidney functioning
10. MUDRA & BANDHAS
The Urethra has 2 sphincters ..
• External sphincter – under voluntary control and
• Internal sphincter – under Involuntary control that is under the ANS .
•Mudras like Vajroli Mudra bring about control on these
sphincters .
•Moolbandha also prevents Urinary Incontinence (leakage of
urine during coughing etc especially in women )
•Uddiyan Bandha – pressure differentials in the abdominal
region
– positive impact on kidney functioning
11. LUNGS
2 LUNGS
• Basic Structural & Functional unit is “Alveoli “ grape shaped
units
• It is through the thin walls of the Alveoli –which are
surrounded by capillaries that the exchange of gases take
place.
• Carbon di oxide , other gaseous substances produced
from cell metabolism…
- along with water – vapour &
- some chemicals like alcohol ….
- all such waste excreted through Respiratory tract
from the lungs
12. LUNGS - Yogic co-relation
ASANAS -
Matsysana, Chakrasana, Bhujangasana , Parvatasana , Ardhamatsyendrasana etc
- expansion of chest /thoracic area
- increase lung functioning
- facilitates the excretion process
PRANAYAMA-
• All pranayama practices..
- facilitate increase in lung functioning capacity
- facilitates optimum excretion of unwanted gases , toxins etc…
- Sukshma star pe “nadi shuddhi“
• In Pranayama
- exhalation – Rechak is prolonged
- effective removal of CO2
- facilitates more intake of O2
13. LUNGS - yogic co-relation
SHUDDHI KRIYA
Kapalbhati & Neti – clears respiratory passage , associated sinuses
& lungs
• KAPALBHATI – The CO2 percentage in blood stimulates the
exhalation through stimulation of the Respiratory Centre in the
brain.
• Practice of Kapalbhati causes continuous excretion of CO2 .
• This results in reduction of CO2 percentage in the blood which
depresses the Respiratory centre leading to a cessation of breath
for a few moments
( Apnea ). Sahaj Kumbhak
14. 2 million sweat glands in the skin…
• regulate body temperature
• responsible for excretion of water & salts from body.
• Asanas performed following PYS through relaxation of efforts. -
prayatnashaithilya
• reduces building up of heat
• preventing excess water loss from skin.
• Asan practice improves peripheral blood circulation –
• helps in maintaining the health of the skin
• Pranayama- As mentioned in granthas , practice of Lower type of
Pranayama causes rise in body temp & causes sweating
• Sitkari- increases pranic flow – results in glowing skin
15. LARGE INTESTINE
• The large intestine or Colon is the organ that removes solid waste from the
body
• Main Sections of Large Intestine…
Ascending Colon including Cecum & Appendix
Transverse Colon
Descending Colon
The major excretory functions of Large Intestine are …
• Reabsorption of water
• Formation of solid waste – faeces
• temporary storage of faeces. ..&
• finally removal of the solid waste
16. LARGE INTESTINE – YOGIC CORELATION
ASANAS –
Most of the Cultural Asanas affect the Abdominal region ..and
therefore the Large Intestine as well
• cause negative or positive pressure in the abdominal cavity.
• Removal of gases –ex- pawanamuktasana
• removes the stagnation of blood in the abdominal cavity
• improved blood circulation in this area …including that of the
Large Intestine
• good massage to the Internal Organs within the cavity
including those of the Excretory System. improves the
Functioning capacity of this System
17. MUDRA & BANDHAS–In general create pressure differentials.
resulting in toning of the abdominal muscles e.g Uddiyan Bandha
-> improves function capacity of the large intestine
Ashwini Mudra & Mulbandha tones up the Anal Sphincters
PRANAYAMA - Effect on movement of diaphragm-
- massage to large intestine as well
- improves blood circulation
- improves functioning of the large intestine
It has been mentioned in granthas that Lower Pranayama practices reduce the
amount of feces & urine
• IN GENERAL
Surya Namaskar improves the functioning capacity of all excretory organs
Sukshma Vyayam removes toxins from all joint & supporting structure areas &
facilitates unobstructed pranic flow
18. SHUDDHI KRIYA
All these cleanses different parts –> excretion of wastes
• Neti- cleanses the Nasal cavity & associated sinuses
• Dhouti cleanses the Food pipe & stomach
• Shankh Prakhshalan- improves peritstaltic movement . cleanses entire GIT.
• Uddiyan Agnisar Nauli –
- Facilitates the cleansing of Abdominal region
- Helps in regularizing peristaltic movements .
- Pressure changes improves blood circulation .
- Improves functioning of intestine
• Basti - cleansing of Rectum –Anal Region
• Ganesh Kriya /Moolshodhan – Anus
• Trataka- at physical level –removal of waste through tears
at mental level - Excretion of negativity – chitta shuddhi
• Kapalbhati – washout of CO2 –physical-apnoea .Keval kumbak – purification of
mind
19. EXCRETION AT MENTAL
TRATAKA ,OM CHANTING , YAM / NIYAM
ANTARANG SADHANA….
• These practices takes one inwards makes the mind stable balanced ,
focussed & at peace
• Decreases outside influences
• Positive influence on Hypothalamus
• Emotions balanced out
• Parasympathetic tone increases – calming effect
• Due to all this Negativity is removed.
• Cleansing at Mental / Emotional levels
• Excretion at thought level happens
meaning Emotional Catharsis
Nurturing of pure thoughts at the chitta level takes places through
various yogic practices
