Scene 2 (7s)

BREATHING RESPIRATION Breathing is the physical process of exchanging gases Respiration is a chemical process which takes place at a cellular level and produces energy. It occurs in the lungs. It takes place in cells. It occurs through respiratory organs like nose, lungs, etc. It happens in cells and cell organelles like mitochondria and more. It occurs outside the cells making it extracellular . It occurs inside the cells making it intracellular. Inhalation is an active process, whereas exhalation is a passive process. Except for some reactions in glycolysis, no other steps require energy..

Scene 3 (34s)

Respiration is defined as a metabolic process where the living organisms obtains the energy..

Scene 4 (44s)

Anaerobic respiration – occurs in the absence of molecular oxygen in the cytoplasm ..

Human Respiratory System - Respiratory organs in various organisms.

Scene 20 (3m 58s)

Respiratory System: How We Breathe. RESPIRATORY SYSTEM The respiratory system is the network of organs and tissues that help you breathe. It includes the airways, lungs and blood vessels..

Scene 21 (4m 10s)


Scene 22 (4m 19s)

Managing IPF Progression - Lungs and You. The lungs are a pair of spongy, air-filled organs located on either side of the chest . The lungs main role is to bring in air from the atmosphere and pass oxygen into the bloodstream . It circulates to the rest of the body. Help is required from structures outside of the lungs in order to breathe properly..

Scene 23 (4m 39s)

Your lungs bring fresh oxygen into your body . They remove the carbon dioxide and other waste gases that your body's doesn't need. To breathe in (inhale), you use the muscles of your rib cage – especially the major muscle, the diaphragm.

Scene 24 (4m 53s)


Scene 25 (5m 5s)

Pleural membranes. Lungs are covered by a double layered pleura, with pleural fluid between them. It reduces friction on the lung-surface..

Scene 26 (5m 18s)

The outer pleural membrane is in close contact with the thoracic lining. The inner pleural membrane is in contact with the lung surface..

Scene 27 (5m 32s)

Thoracic Chamber. The lungs are situated in the thoracic chamber which is anatomically an air-tight chamber.

Respiratory System Lungs Body Human respiratory system Respiratory system Respiratory.

Scene 30 (6m 6s)

The part starting with the external nostrils up to the terminal bronchioles transports the atmospheric air to the alveoli, clears it from foreign particles, humidifies and also brings the air to body temperature.

Scene 31 (6m 19s)

The alveoli and their ducts form it It is the site of actual diffusion of O 2 and CO 2 between blood and atmospheric air ..

Scene 32 (6m 32s)

NOSTRILS Pathway of air ALVEOLI.

Scene 33 (6m 38s)

NOSTRILS. Humans Have Four Nostrils - KnowledgeNuts.

Scene 34 (6m 53s)

PHARYNX. It is the common passage for food and air. Opens into trachea through Larynx..

Scene 35 (7m 4s)

LARYNX. Larynx is a cartilaginous box. It helps in sound production and hence called the sound box.

Scene 36 (7m 16s)

TRACHEA. Trachea is a straight tube. Extend upto the mid-thoracic cavity. It divides at the level of 5th thoracic vertebra into a right and left primary bronchi..

Scene 37 (7m 29s)

BRONCHI, BRONCHIOLES & ALVEOLI. Each bronchi undergoes repeated divisions to form the secondary and tertiary bronchi and bronchioles ending up in very thin terminal bronchioles..

Scene 38 (7m 41s)

ALVEOLI. Each terminal bronchiole gives rise to a number of very thin, irregular-walled and vascularised bag-like structures called alveoli..

Scene 39 (7m 51s)

STEPS OF RESPIRATION. ( i ) Breathing or pulmonary ventilation by which atmospheric air is drawn in and CO2 rich alveolar air is released out. (ii) Diffusion of gases (O2 and CO2 ) across alveolar membrane. (iii) Transport of gases by the blood. (iv) Diffusion of O2 and CO2 between blood and tissues. (v) Utilisation of O2 by the cells for catabolic reactions and resultant release of CO2.

Scene 43 (8m 43s)

The volume of air involved in breathing movements can be estimated by using a spirometer which helps in clinical assessment of pulmonary functions.

Scene 44 (9m 0s)

BREATHING. What is breathing ? . breathing (pulmonary ventilation) is the inflow of atmospheric air and release (outflow) of carbon dioxide rich alveolar air ..

Scene 45 (9m 11s)

Breathing Mainly Involves Two Steps : Inspiration - It Is An Active Process By Which Fresh Air Enters The Lungs . Expiration – It Is A Passive Process By Which Co2 Is Expelled Out From The Lungs.

Scene 46 (9m 27s)

STAGES OF BREATHING. INSPIRATION EXPIRATION Atmospheric air is drawn in The alveolar air is released out It occur if the pressure within the lungs (intra-pulmonary pressure) is less than the atmospheric pressure. There is a negative pressure in the lungs with respect to atmospheric pressure It takes place when the intra-pulmonary pressure is higher than the atmospheric pressure.

Scene 47 (9m 47s)

Diaphragm- contracts ribs and the sternum- lift up thoracic volume- increases pulmonary volume- increases intra-pulmonary pressure- decreases.

Scene 48 (9m 59s)

Diaphragm- relaxes ribs and the sternum- normal thoracic volume- reduces pulmonary volume- reduces intra-pulmonary pressure- increases.
