Circulatory system

CIRCULATORY SYSTEM

The circulatory system is a vast network of organs and vessels that is responsible for the flow of blood, nutrients, hormones, oxygen and other gases to and form cells. Without the circulatory system, the body would not be able to fight diseases or maintain a stable internal environment such as proper temperature and pH - known as homeostasis.

While many view the circulatory system, also known as the cardio vascular system, as simple as highway for blood it is made up of three independent systems that work together ; the heart, lungs and arteries, veins, coronary and portal vessels according to the U.S MLM.

The heart, blood and blood vessels make up the cardiovascular component of the circulatory system. The pulmonary circulatory system sends oxygen- depleted blood away from the heart through the pulmonary artery to the lungs and returns oxygenated blood to the heart through the pulmonary vein.

Oxygen deprived blood enters the right atrium of the heart and flow through the tricuspid value into the right ventricle. From their it pumped through the pulmonary semilunar value into the pulmonary artery on its way to the lungs. When it gets to the lungs, the carbon dioxide is released from the blood and oxygen is absorbed. The pulmonary vein sends the oxygen rich blood back to the heart according to NLM.

The system is circulation is the portion of the circulatory system is the network of veins, arteries and vessels that transports blood from heart, services the body's cells and then re-enters the heart the mayo clinic noted.

Respiratory system | Parts of respiratory system with their functions and structures

RESPIRATORY SYSTEM

The human respiratory system is a series of organs responsible for taking in oxygen and expelling carbon dioxide. The primary organs of the respiratory system are lungs which carry out this exchange of gases as we breathe.

Parts of respiratory system with their functions and structures :-

As we breathe, oxygen enters the nose or mouth and passes the sinuses which are hollow spaces in the skull. Sinuses help regulate the temperature and humidity of the air we breathe.

The trachea, also called as wind pipe, filters the air that is inhaled, according to the American Lung Association. It branches into the bronchi which are two tubes that carry air into each lung.

The bronchial tubes lead to the lobes of the lungs. The right lung has three lobes, the left lung has two lobes. Lobes are filled with small sacs called alveoli, and this is where the exchange of oxygen and carbon dioxide occurs.

The alveolar walls are extremely thin (about 0.2 micrometers). These walls are composed of single layer of tissues called epithelial cells and tiny blood vessels called pulmonary capillaries.

Blood passes through the capillaries. The pulmonary artery carries blood containing carbon dioxide to the air sacs, where the gas moves from the blood to the air , according to the NHLBI. Oxygenated blood goes to the heart through the pulmonary vein and the heart pumps it throughout the body. The diaphragm, a dome shaped muscle at the bottom of the lungs, control breathing and separates the chest cavity from the abdominal cavity. When a breath is taken, it flattens out and pulls the forward making more space for lungs. During exhalation, the diaphragm expands and forces air out.

Difference between Yogasan and Exercise

Difference Between Yogasan And Exercise

In the current western culture, yoga and exercise are popular ways to stay in shape but the two have a number of differences in regards to the ultimate goal and the specific benefits that they can have on your mind and body.

The ultimate aim of Hatha yoga is to reach samadhi, a higher state of consciousness. In order to purify the mind it is necessary for the body to undergo a process of absolute purification in order to remove impurities so the udic function and the energy blocks are released. The main objective of Hatha yoga is to create an absolute balance of the interacting activities and processed of the Physical body, mind and energy. When this balance is created, the impulses generated give a call of awakening to the central force (Sushumna nodi) which is responsible for the evolution of human consciousness. If Hatha yoga is not used for the purpose, its true objective is lost.

The ultimate aim of exercise is to improve overall physical fitness level and health by practicing aerobic activity, which elevates the heart beat rate. Exercise can strengthen muscles and the cardiovascular system, improve athletic skills and aid weight loss. Regular exercise can boost the immune system and also improve mental health e.g. prevent depression and promote/ maintain positive self-esteem.

Further more, exercise in the form of different sports can be practiced competitively and the aim is to be the best within the sport, which can be an external driver to the individuals performance.

The difference between yoga and exercise will depend on the type of yoga exercise being practiced and it should be noted that certain type of yoga e.g. Ashtanga and more vigorous than other forms and therefore share more similarities with exercise. However, general physical differences are outlined below :

1) Yoga practices slow dynamic movements.

2) Low risk of injuries/exercise has a higher risk of injury.

3) Yoga leads to relatively low caloric consumption/exercise leads to moderate to high caloric consumption.

4) Yoga is non-competitive, process, oriented/exercise is commonly competitive, goal-oriented.

छात्रों में बढ़ती अनुशासन हीनता पर निबन्ध | हिन्दी निबन्ध

निबन्ध

छात्रों में बढ़ती अनुशासन हीनता

प्रस्तावना :

'अनुशासन ' शब्द का अर्थ है - 'शासन अर्थात व्यवस्था के अनुसार जीवन - यापन करना। ' यदि कोई व्यवस्था निश्चित है तो उसके अनुसार जीना। यदि व्यवस्था निश्चित नहीं है तो जीवन में कोई नियम - व्यवस्था या क्रम बनना। अनुशासन जीवन को चुस्त - दुरुस्त बना देता है। इससे कार्यकुशलता बढ़ती है। समय का पूरा - पूरा सदुपयोग होता है। पर क्या आज ऐसा हो रहा हैं ?

अनुशासन की प्रथम पाठशाला परिवार :

अनुशासन का पाठ पहले - पहल परिवार से सीखा जाता है। यदि परिवार में सब कार्य व्यवस्था किए जाते है तो बच्चा भी अनुशासन सीख जाता है। इस लिए मनुष्य को सबसे पहले अपना घर अनुशासित करना चाहिए। परन्तु आज घर - घर नहीं रह गए है। सब जगह एकल परिवार का चलन हो गया है। ऐसे में माँ - बाप को अपने बच्चो के लिए समय ही नहीं होता है , वो अपने बच्चो के लिए नौकर रखते हैं और भला कोई नौकर बच्चे को अनुशासन सिखा सकता हैं , क्या ? उन्हें तो बच्चे को देखना है , अपनी तन्खा देखनी है और घर जाना है। ऐसे में बच्चे अनुशासन कहाँ से सीखेंगे।

अनुशासन हीनता का प्रभाव :

छात्र जिन्हे सदेव अनुशासन का पाठ पढ़ाया जाता है , उनकी जिंदगी में अनुशासन के लिए अब जैसे को जगह ही नहीं रह गई हैं। यह युग वैज्ञानिक युग है इसलिए किसी को किसी की चिंता नहीं है सब अपने - अपने में ही व्यस्त रहते है। कोई जानना तक नहीं चाहता है कि उसके परिवार , विद्यालय , नगर , छेत्र , देश आदि में क्या - क्या घट रहा है। आज बच्चे अपने बड़ो को कोई तवज्जो ही नहीं देते हैं और छात्र अपने शिक्षकों को।

उपसंहार :

वास्तव में अनुशासन एक स्वभाव है। एक विद्या है। अनुशासन का लक्ष्य है - जीवन को समधुर और सुविधापूर्ण बनाना। अनुशासित व्यक्ति को सुशिक्षित और सभ्य कहा जाता है। वह न केवल स्वच्छता पर ध्यान देता है , बल्कि अपनी बोलचाल और व्यवहार पर भी ध्यान देता है। वह समाज के बीच खलन नहीं डालता , बल्कि व्यवहार की गरिमा बढ़ाता है। इस प्रकार अनुशासन जीवन - मूल्य है , मनुष्य का आदर्श हैं। छात्रों के लिए उनकी पहचान हैं।
