Introduction:
Human Respiratory System sharir ka wo hissa hai jo humein saans lene mein madad karta hai. Iska sabse mukhya kaam (main function) hai sharir ke har hisse tak Oxygen (O2) pahunchana aur sharir se Carbon Dioxide (CO2) ko bahar nikalna.
Ek Nursing student ke taur par aapko ye pata hona chahiye ki bina oxygen ke hamara dimaag aur dil kaam karna band kar sakte hain. Isiliye, respiratory system ki jankari hona life-saving ho sakta hai.
Respiratory System ke Mukhya Ang (Major Organs)
Respiratory system ko hum do (2) parts mein baant sakte hain:
Upper Respiratory Tract: Ismein naak (nose), pharynx, aur larynx aate hain.
Lower Respiratory Tract: Ismein trachea, bronchi, aur lungs (फेफड़े) aate hain.
1. Upper Respiratory Tract (Upar wala Swasan Tantra)
Upper Respiratory Tract ka mukhya kaam bahar ki hawa ko andar bhejne se pehle use saaf, num (moist), aur garam karna hota hai. Ismein niche diye gaye ang shamil hain:
Is tract mein ye 3 mukhya ang (organs) hote hain:
Naak aur Nasal Cavity (Nose)
Pharynx (Throat/Gala)
Larynx (Voice Box)
1. Naak aur Nasal Cavity (Nose)
Hawa sabse pehle hamari naak ke zariye sharir mein pravesh karti hai. Naak aur Nasal Cavity (Nose) ke kai zaroori kaam hain:
Filtration: Naak ke andar chote-chote baal hote hain jinhe Cilia kehte hain. Ye bahar ki dhool aur mitti ko rok lete hain taaki wo lungs mein na jayein.
Warming: Bahar ki thandi hawa ko hamare sharir ke taapman (body temperature) ke barabar garam karna.
Humidification: Hawa mein nami (moisture) milana taaki saans ki nali sukhe nahi.
2. Pharynx (Gala ya Throat)
Nasal cavity ke thik piche ek muscular tube hoti hai jise Pharynx kehte hain. Ye lagbhag 5 inch lambi hoti hai. Nursing mein aapko pata hona chahiye ki Pharynx ek aisa rasta hai jahan se hawa aur khana dono guzarte hain.
Pharynx ke teen hisse hote hain:
Nasopharynx: Jo naak ke piche hota hai.
Oropharynx: Jo munh (mouth) ke piche hota hai.
Laryngopharynx: Jo niche ki taraf larynx se juda hota hai.
3. Larynx (Voice Box)
Larynx ko hum 'Voice Box' bhi kehte hain kyunki yahin se hamari awaz paida hoti hai. Iska sabse mahatvapurn hissa Epiglottis hota hai.
Professor's Note: Epiglottis ek patte (leaf) jaisa dhakkan hota hai. Jab hum khana nikalte hain, toh ye saans ki nali ko band kar deta hai taaki khana lungs mein na chala jaye. Agar ye sahi se kaam na kare, toh mareez ko 'Choking' (saans rukna) ho sakti hai.
2. Lower Respiratory Tract (Niche wala Swasan Tantra)
Jab hawa Larynx se guzarti hai, toh wo Lower Respiratory Tract mein pravesh karti hai:
Ismein niche diye gaye 4 mukhya ang shamil hain:
Trachea (Windpipe)
Bronchi aur Bronchioles
Lungs (फेफड़े)
Alveoli
1. Trachea (Windpipe)
Larynx ke thik niche se Trachea (Windpipe) shuru hoti hai. Ise 'Saans ki Nali' bhi kaha jata hai.
Structure: Ye lagbhag 10 se 12 cm lambi hoti hai. Ismein 16-20 'C' shape ke cartilages (haddi jaisa naram hissa) hote hain.
Karya (Function): Ye cartilages trachea ko chipakne (collapse) se rokte hain, taaki hawa ka rasta humesha khula rahe.
Cilia: Iske andar bhi chote baal hote hain jo mucus ko upar ki taraf dhakelte hain taaki kachra bahar nikal sake.
2. Bronchi aur Bronchioles
Trachea niche jakar do hisson mein bat jati hai, jinhe Right aur Left Bronchi kehte hain.
Bronchi: Ye lungs ke andar ghuste hi aur choti naliyon mein bat jati hain.
Bronchioles: Jab ye naliyan bahut barik ho jati hain (jaise ped ki tahniyan), toh inhe Bronchioles kehte hain. Inmein cartilage nahi hota, isliye asthma mein ye naliyan jaldi sikud jati hain.
3. Lungs (Hamare Fephde)
Lungs respiratory system ke sabse bade ang hain. Ye spongy aur gulabi rang ke hote hain.
Right Lung: Ismein 3 Lobes hote hain. Ye thoda bada hota hai.
Left Lung: Ismein sirf 2 Lobes hote hain kyunki left side mein dil (Heart) ke liye jagah honi chahiye (Cardiac Notch).
Pleura: Lungs ke upar ek double layer ki jhill (membrane) hoti hai jise Pleura kehte hain. Ye lungs ko ragad se bachati hai.
4. Alveoli (Gas Exchange ka Kendra)
Bronchioles ke aakhri sire par angur ke guchhon jaisi choti thailiyan hoti hain, jinhe Alveoli kehte hain.
Yahin par asli magic hota hai! Khoon ki barik naliyan (capillaries) alveoli ko gheri rehti hain.
Oxygen alveoli se khoon mein jati hai aur $CO_2$ khoon se alveoli mein aakar bahar nikal jati hai.
Swasan Prakriya Kya Hai? (Introduction)
Inhalation (साँस अंदर लेना)
Exhalation (साँस बाहर छोड़ना)
Hamare seene (Chest cavity) mein dubaav (pressure) badalne ki wajah se hi hawa andar-bahar hoti hai. Ismein sabse bada haath Diaphragm (ek majboot manspeshi jo lungs ke niche hoti hai) ka hota hai.
1. Inhalation (Inspiration) - Saans Andar Lena
Inhalation wo prakriya hai jisme bahar ki taaza oxygen-yukt hawa hamare lungs mein pravesh karti hai. Is dauran hamara sharir ye badlav karta hai:
Diaphragm ka kaam: Diaphragm niche ki taraf sikudta (contracts) hai aur bilkul flat ho jata hai.
Intercostal Muscles: Hamari pasliyon (ribs) ke beech ki muscles pasliyon ko upar aur bahar ki taraf khinchti hain.
Chest Cavity ka Size: In dono badlavon se seene ke andar ki jagah badh jati hai.
Pressure ka Khel: Jab jagah badhti hai, toh lungs ke andar hawa ka dubaav (pressure) kam ho jata hai. Bahar ka pressure zyada hone ki wajah se hawa turant naak se hote huye lungs mein bhar jati hai.
2. Exhalation (Expiration) - Saans Bahar Chhodna
Jab hamara sharir oxygen istemal kar leta hai, toh carbon dioxide ($CO_2$) ko bahar nikalna zaroori hota hai. Is prakriya ko Exhalation kehte hain.
Diaphragm ka Relaxation: Diaphragm wapas apni purani jagah (dome shape) par upar ki taraf aa jata hai.
Ribs ka niche aana: Pasliyan wapas apni jagah par niche aa jati hain.
Pressure badhna: Seene ke andar ki jagah kam ho jati hai, jisse lungs par dubaav padta hai aur gandi hawa (CO2) bahar nikal jati hai.
Respiratory System se Judi Beemariyan
mukhya beemariyon ko vistar se samajhte hain.
1. Asthma (दमा)
Asthma ek aisi bimaari hai jisme saans ki naliyan (bronchioles) sikud jati hain aur unmein sujan aa jati hai.
Lakshan (Symptoms): Saans lene mein "Seeti" jaisi awaz aana (Wheezing), seene mein jakdan, aur raat mein tez khansi.
Karan (Causes): Dhool, dhuua, thandi hawa ya pollen grains se allergy.
2. Pneumonia (न्यूमोनिया)
Pneumonia lungs mein hone wala ek gambhir infection hai. Ismein lungs ke andar ki thailiyan (Alveoli) mein pani ya pus (pas) bhar jata hai.
Lakshan (Symptoms): Tez bukhaar, thand lagna, aur balgam wali khansi. Bache mein pasliyan chalna (Chest indrawing) iska sabse bada sanket hai.
Karan (Causes): Bacteria, Virus ya Fungi ka infection
3. Tuberculosis - TB (क्षय रोग)
TB ek sankramak (infectious) bimaari hai jo Mycobacterium tuberculosis naam ke bacteria se hoti hai. UP mein iske mareez bahut milte hain.
Lakshan (Symptoms): 2 hafte se zyada khansi, sham ko bukhar aana, wazan kam hona, aur balgam mein khoon aana.
Ilaj: Iska poora ilaj DOTS ke zariye sarkari hospital mein muft milta hai.
4. COPD (Chronic Obstructive Pulmonary Disease)
Ye beemari un logo ko zyada hoti hai jo bahut saalon se smoking kar rahe hain ya chulhe ke dhuue mein khana bana rahi hain. Ismein lungs hamesha ke liye damage ho jate hain.
Respiratory System ko Swasth Rakhne ke Upay (Health Tips)
1. Dhuyein aur Pradushan se Bachav (Pollution Control)
Gramin kshetron mein respiratory system kharab hone ka sabse bada karan dhuaan hai.
Chulhe ka Dhuaan: Gaon mein mahilayein mitti ke chulhe par khana banati hain. Is dhuue mein saans lena 100 cigarette peene ke barabar hota hai.
Tip: Unhe "Unnat Chulha" ya LPG ka prayog karne ko kahein. Khana banate samay rasoi ki khidkiyan khuli rakhein.
Dhoombrapan (Smoking): Bidi aur cigarette fephdon ke alveoli ko hamesha ke liye damage kar dete hain.
Tip: Logon ko "No Smoking" ke liye prerit karein.
2. Swasth Ahaar (Healthy Diet)
Jo hum khate hain, uska asar hamare lungs ki capacity par padta hai.
Pani ki matra: Din mein kam se kam 8-10 glass pani piyein. Pani lungs ke mucus (balgam) ko patla rakhta hai, jisse saans lene mein asani hoti hai.
Antioxidant-rich Food: Vitamin C wale phal jaise Aanvla, Nimbu, aur Santra fephdon ke infections se ladne mein madad karte hain.
Adrak aur Tulsi: Inka kadha saans ki naliyon ki sujan kam karta hai.
3. Swasan Vyayam (Breathing Exercises)
Lungs ki capacity badhane ke liye exercises bahut zaroori hain.
Deep Breathing (Gehri Saans): Roz 10-15 minute subah uthkar gehri saans lene se fephdon ke wo hisse bhi khul jate hain jo aam taur par istemal nahi hote.
Pranayam: Yoga jaise Anulom-Vilom aur Kapalbhati respiratory system ke liye vardaan hain.
