Respiration is the process by which organisms release energy from food through breakdown reactions with oxygen. There are two types of respiration: aerobic respiration, which requires oxygen, and anaerobic respiration, which does not. Aerobic respiration fully breaks down glucose and produces carbon dioxide, water, and a large amount of energy. Anaerobic respiration incompletely breaks down glucose and produces different end products with less energy yield, such as lactic acid or ethanol. The human respiratory system involves inhaling oxygen into the lungs and exhaling carbon dioxide. It consists of the nostrils, throat, trachea, bronchi, and alveoli in the lungs where gas exchange occurs through blood vessels in the alveolar walls.

Respiration
The document discusses respiration and the effects of smoking. It begins by defining aerobic and anaerobic respiration and describing how lactic acid builds up in muscles during exercise. It then explains how respiration works to produce ATP and the role of oxygen. The effects of smoking are outlined, including how carbon monoxide reduces oxygen transport, how tar increases cancer risk, and how smoking can lead to diseases like chronic bronchitis, emphysema and lung cancer. Experiments are described to show that carbon dioxide and heat are byproducts of respiration.
Respiration & gas exchange
Respiration is defined as the transport of oxygen from the outside air to the cells within tissues, and the transport of carbon dioxide in the opposite direction.
The physiological definition of respiration should not be confused with the biochemical definition of respiration, which refers to cellular respiration: the metabolic process by which an organism obtains energy by reacting oxygen with glucose to give water, carbon dioxide and ATP (energy). Although physiologic respiration is necessary to sustain cellular respiration and thus life in animals, the processes are distinct: cellular respiration takes place in individual cells of the organism, while physiologic respiration concerns the bulk flow and transport of metabolites between the organism and the external environment.
Respiration
Respiration is the release of energy from food through oxidation, producing carbon dioxide and water. There are two types of respiration: aerobic respiration, which occurs in mitochondria and releases more energy using oxygen; and anaerobic respiration, which does not use oxygen. Breathing is the mechanical process of inhaling oxygen into the lungs and exhaling carbon dioxide and water out of the lungs to facilitate respiration. Inspired air contains more oxygen and less carbon dioxide than expired air due to respiration consuming oxygen and producing carbon dioxide.

Powerpoint respiration
1. Respiration is the process by which living cells produce energy from food sources like glucose.
2. Aerobic respiration uses oxygen to fully break down glucose into carbon dioxide and water, producing more energy. Anaerobic respiration breaks down glucose without oxygen, producing less energy.
3. In humans, muscles use anaerobic respiration during intense exercise when oxygen delivery is insufficient, producing lactic acid as a byproduct which must later be broken down.
LIFE PROCESSES
Respiration is the process of oxidizing glucose and other respiratory substrates to release energy in the form of ATP. There are two types of respiration: aerobic respiration, which occurs in the presence of oxygen and breaks substrates down completely to CO2 and H2O; and anaerobic respiration, which occurs without oxygen and incompletely breaks substrates down to produce substances like lactic acid. The human respiratory system consists of the respiratory tract and respiratory organs. The respiratory tract includes the nostrils, nasal cavity, pharynx, and trachea, while the respiratory organs are the pair of lungs, which are divided into bronchi, bronchioles, alveolar ducts, and alveoli where gas exchange occurs.

Respiration in human beings
Respiration involves two processes - breathing, which is the exchange of gases between the atmosphere and cells, and cellular respiration, which breaks down food inside cells to release energy. In humans, respiration occurs through a respiratory system that filters and transports air through the nasal cavity, pharynx, larynx, trachea, bronchi, bronchioles, alveoli and blood capillaries, facilitating gas exchange between inhaled air and blood. The diaphragm and intercostal muscles control breathing by expanding and contracting the lungs to inhale and exhale air.
The Human Respiratory System
The document provides information about the human respiratory system. It describes the key parts of the respiratory system including the nostrils, nasal cavity, pharynx, trachea, bronchi, bronchioles, lungs and diaphragm. It explains that the respiratory system works to intake oxygen and remove carbon dioxide through the process of breathing, which involves inspiration and expiration achieved through contraction and relaxation of the diaphragm and chest muscles. Gas exchange takes place in the alveoli of the lungs, where oxygen passes into the blood and carbon dioxide passes out.
Class 7 Respiration
1. Respiration is a chemical process involving the intake of oxygen, oxidation of food, release of energy, and elimination of carbon dioxide.
2. Breathing is the mechanical process of pumping air in and out of the lungs, while respiration is the chemical exchange of gases between the air and cells.
3. During inhalation, the diaphragm and ribs expand the thoracic cavity, lowering air pressure and allowing air to rush in. During exhalation, they return to their original position, increasing air pressure and pushing air out.
The human respiratory system ppt.1pptx
The human respiratory system consists of the nose, pharynx, larynx, trachea, bronchi, bronchioles, lungs, diaphragm and intercostal muscles. Air enters the lungs through the nose and mouth, and passes through the trachea into the bronchi and bronchioles before reaching the alveoli in the lungs. Oxygen and carbon dioxide are passively exchanged between the alveolar air and blood through the process of diffusion. Contraction of the diaphragm and intercostal muscles during inhalation lowers the pressure in the thoracic cavity, drawing air into the lungs. During exhalation, relaxation of these muscles increases pressure and pushes air out.
The human respiratory system
The human respiratory system consists of the nose, pharynx, larynx, trachea, bronchi, bronchioles, lungs, diaphragm and intercostal muscles. Air enters the body through the nose and travels through the trachea into the lungs. In the lungs, oxygen diffuses into the bloodstream and carbon dioxide diffuses out of the bloodstream and into the air sacs. The diaphragm and intercostal muscles help draw air into and push air out of the lungs during breathing.
Respiratory system
The respiratory system is made up of organs involved in the exchange of oxygen and carbon dioxide. It includes the nose, mouth, throat, voice box, windpipe, lungs, and the processes of inhalation and exhalation. The upper respiratory tract comprises the nose, nasal cavity, sinuses and larynx while the lower respiratory tract is made up of the lungs, bronchi and bronchioles, and alveoli. Respiration can be aerobic, using oxygen to produce energy, or anaerobic, producing energy without oxygen. Common respiratory diseases include asthma, bronchitis, pneumonia and tuberculosis.
Breathing & Respiration

The document discusses different ways that organisms break down glucose to produce energy. In the first step, glucose is broken down into pyruvate. Pyruvate is then broken down through different pathways: in aerobic respiration it is broken down into carbon dioxide and water with energy release in mitochondria; in yeast it is fermented into ethanol and carbon dioxide during anaerobic respiration; in human muscles it is converted to lactic acid during anaerobic respiration due to lack of oxygen. Aerobic respiration fully oxidizes glucose while anaerobic respiration incompletely breaks it down.

LIFE PROCESSES PART- 4.pptx
The document discusses cellular respiration and the human respiratory system. It describes how terrestrial organisms have an advantage over aquatic ones in obtaining oxygen from the air. It explains that in humans, air is brought into the lungs through the nostrils and trachea, and then passes through increasingly smaller bronchioles and alveoli, where gas exchange occurs. Oxygen binds to hemoglobin in red blood cells and is transported throughout the body, while carbon dioxide is transported back to the lungs and exhaled. The process of aerobic cellular respiration uses oxygen to fully break down glucose, producing much more energy than anaerobic respiration which occurs without oxygen.
Grade 7 Respiration in organisms.pdf
Breathing involves inhaling oxygen and exhaling carbon dioxide through respiratory organs like the nose, mouth, and lungs. It is a voluntary physical process. Cellular respiration is the involuntary chemical process where glucose and oxygen are broken down in cells to produce energy in the form of ATP. It occurs in the mitochondria of cells. Both processes are essential - breathing supplies oxygen for cellular respiration to produce energy for cellular functions.
Respiratory Fernando
The document summarizes the human respiratory system. It describes the upper respiratory tract including the larynx, trachea and bronchi. The lower respiratory tract includes the lungs, which transport air to alveoli for gas exchange. Breathing in is called inspiration, which involves the diaphragm lowering and ribs raising. Breathing out is called expiration, with opposite muscle movements. Oxygen passes from alveoli to blood vessels, while carbon dioxide passes from blood to alveoli. Respiration provides energy through aerobic and anaerobic processes. Common respiratory disorders include asthma, emphysema and bronchitis.
Unit3NutritionalprocessRespiratory
The document discusses respiration and the human respiratory system. It explains that food and oxygen react in cells to provide energy, with carbon dioxide produced as a waste product. It then describes the major parts of the respiratory system including the nose, mouth, pharynx, larynx, trachea, bronchi, lungs, bronchioles and alveoli. The diaphragm and intercostal muscles help with inhalation and exhalation by expanding and contracting the chest and lungs. Gas exchange occurs in the alveoli where oxygen passes into blood and carbon dioxide passes out.

- 1. Good afternoon BIOLOGY PROJECT RESPIRATION S.Hari krishnaa X-C
- 2. WHAT IS RESPIRATION? � The process of releasing energy from food is called respiration. � There are two type of respiration Aerobic Respiration Anaerobic Respiration Respiration that take place in the presence of oxygen Respiration that take place in the absence of oxygen
- 3. Breakdown of Glucose in various pathways � ⑴ In presence of oxygen : - Breaking down of glucose into pyruvate takes place in Mitochondria of a cell. - End products are CO₂ , H₂O and energy. ⑵ In insufficient presence of oxygen : - In muscle cells, due to insufficient presence of oxygen the cells undergoes anaerobic respiration. - End products are Lactic acid and lot amount of energy. ⑶ In absence of Oxygen : - In absence of Oxygen, glucose breakdown into pyruvate in cytoplasm only. - End product are Ethanol, and small amount of energy.
- 4. Glucose (6-carbon molecules) In cytoplasam Presence of oxygen Lack of oxygen Absences of (mitochondrial) (in human oxygen muscle cells) (Yeast) CO2+water+energy Latic acid+Energy Ethanol+CO2+Energy Pyruvate (3 carbon molecule)
- 5. Respiration in animals:- What is the Respiratory System? � inhaling of oxygen and exhaling of carbon dioxide is called respiration. � The human being use respiratory system for the process of respiration. � The human respiratory system consists of a group of organs and tissues that help us to breathe. � Lungs are the primary organs of the respiratory system which help in the exchange of gases.
- 6. ABOUT RESPIRATORY SYSTEM � In Human being air is taken into the body through the nostrils. � The air passing through the nostrils is filtered by fine hairs.then the air passes through the throat and into the lungs. � Rings of cartilage are present in the throat which ensures that the air-passage does not collapse. � In lungs the passage divides into smaller and smaller tubes finally terminate in balloon-like structure it is called alveoil. � The alveoile provide the surface where the exchange of gases take place.The wall of aveoile contain an extensive network of blood vessels. � When we breathe in,chest cavity becomes large due to lifting of our ribs and flattening of diaphragm.
- 7. � Because of this , air is suked into lungs and fills the alveoli. The blood brings carbon dioxide from rest of the body and release into the alveoli,and oxygen in thee alneolar air is taken up by blood and transported to various cells in our body. � When air is taken in and let out , lungs always contain a residual volume of air so that is sufficent time for oxygen to be absorbed and carbon dioxie to be released.
