This power point presentation summarizes the respiratory systems of various organisms. Amoebas do not have a specialized respiratory system and instead rely on oxygen entering and carbon dioxide leaving through their cell membranes. Earthworms, cockroaches, and scorpions use their skin as a respiratory organ, while fish rely on gills and frogs can breathe through their moist skin, mouth, or lungs depending on their environment. Some bacteria and yeast are able to produce energy without oxygen through anaerobic respiration involving only glycolysis.

Animal tissues, 9 cbse
Animal tissues are divided into four main types - epithelial tissue, connective tissue, muscle tissue, and nervous tissue. Epithelial tissue covers the internal and external surfaces of the body and its main functions include secretion, absorption, protection, and filtration. It is made up of cells that are arranged in one or more layers. Connective tissues are found throughout the body and function to bind, support, and connect other tissues. They contain fibers and ground substances along with loosely arranged cells. The major liquid connective tissue in the body is blood, which contains plasma and three main types of corpuscles - red blood cells, white blood cells, and platelets.
Respiration in organism class 7
Respiration occurs in both plants and animals and involves the breakdown of glucose to release energy. It has three phases: internal respiration which is the exchange of gases between the body and environment, external respiration which is the transport of oxygen into cells and carbon dioxide out via blood, and cellular respiration which is the breakdown of food in cells. Aerobic respiration uses oxygen to fully break down glucose and produce more ATP, while anaerobic respiration occurs without oxygen and produces less ATP. Respiration takes place via various organs and structures depending on the organism, such as lungs in humans and gills in fish.

9th sound NCERT
The human ear has three main parts - the outer, middle, and inner ear. Sound waves enter the outer ear and cause the eardrum to vibrate. These vibrations are amplified by the three smallest bones in the human body in the middle ear. They transmit the vibrations to the inner ear, where fluid in the cochlea sets up electrical signals in auditory nerves that travel to the brain. The brain then interprets these signals as sound.
Grade IX science L.no.1.matter in our surrounding
Matter is made up of tiny particles that are constantly in motion. The particles are attracted to each other but have space between them. A substance can exist in three physical states - solid, liquid, or gas - depending on how closely the particles are packed and how much they are moving. Changing the temperature or pressure can cause a substance to change states, such as melting from a solid to a liquid or boiling from a liquid to a gas. Evaporation is when a liquid turns to a gas below the boiling point, such as water evaporating from clothes on a clothesline.

Respiration in Organism
Respiration is the process by which organisms produce energy from food through cellular respiration. It occurs in the mitochondria of cells and requires oxygen. There are two types of respiration: aerobic respiration, which uses oxygen and produces carbon dioxide and water, and anaerobic respiration, which occurs without oxygen and produces substances like alcohol or lactic acid. Breathing is the process of inhaling and exhaling air for respiration through organs like lungs, gills, or skin depending on the organism. The rate of breathing increases with physical activity and decreases at rest.
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.
Control and coordination
This document summarizes coordination and control in the human body. It discusses how the nervous system and endocrine system work together to coordinate the body's activities. The nervous system uses neurons, nerve impulses, and reflex arcs to transmit signals rapidly. The endocrine system releases hormones that travel via the bloodstream to regulate functions like growth, metabolism, and stress response. Key glands discussed include the hypothalamus, pituitary, thyroid, adrenals, and reproductive organs, along with the hormones they secrete to maintain homeostasis.
Biology
This document discusses respiration in different organisms. It explains that while cellular respiration is similar across organisms, they use different respiratory organs suited to their environment. Amoebas use their cell membrane, earthworms use their skin, cockroaches use a tracheal system, scorpions use book lungs, fish use gills, and frogs can use their skin, mouth or lungs depending on life stage. The complexity of respiratory organs increases with the complexity of the organism.
Respiration in animals
The document discusses respiration in different animals. It explains that in amoebas, oxygen enters and carbon dioxide exits through the cell membrane, which acts as the respiratory surface. It describes that frogs respire through their skin, lungs, and the lining of their pharynx. It details that fish breathe through their gills, with water flowing over the gills in the opposite direction of blood flow to facilitate oxygen diffusion. Finally, it states that earthworms respire through their moist skin, with gases diffusing between the blood and atmosphere.

POWERPOINT PRESENTATION
The document discusses respiration in different organisms. It states that respiration becomes more complex as organism structure increases in complexity. Amoebas have no organs and respire through their cell membrane. Fish have gills as respiratory organs that allow oxygen from water to diffuse into capillaries and carbon dioxide to diffuse out. Frogs can breathe through their moist skin, mouth or lungs, while tadpoles breathe through gills. Some bacteria can undergo anaerobic respiration without oxygen through glycolysis alone.
Physiology of Respiration in Invertebrates
In physiology, respiration is the movement of oxygen from the outside environment to the cells within tissues, and the removal of carbon dioxide in the opposite direction. In these slides you will get to know about Physiology of Respiration in Invertibrates.
Respiratory system of humans
The document outlines the structures and functions of the human respiratory system and the processes of respiration. It discusses that respiration provides energy to cells through the breakdown of glucose and involves the exchange of oxygen and carbon dioxide between the lungs and blood (external respiration) and between the blood and cells (internal respiration). It also describes the stages of inhalation and exhalation during breathing and different types of respiration such as aerobic and anaerobic. Common respiratory disorders are also listed along with an assignment on the topics covered.
Respiration in living organisms CLASS 7
The document discusses respiration in living organisms. It explains that all cells require energy to function, which they obtain through respiration by taking in oxygen and releasing carbon dioxide. There are two types of respiration - aerobic, which requires oxygen, and anaerobic, which does not. It provides examples of different organisms that undergo aerobic respiration (humans and most animals) and anaerobic respiration (yeasts and muscles during heavy exercise). The mechanisms of respiration and gas exchange vary between organisms and include lungs, gills, diffusion through skin or pores.
breathing gas exchange
The document discusses the process of breathing and the human respiratory system. It defines breathing as the process of gas exchange that occurs during inhalation and exhalation, resulting in oxygen intake and carbon dioxide loss. The respiratory system allows this gas exchange through specialized structures like lungs. The human respiratory system includes the nose, pharynx, larynx, trachea, bronchi, bronchioles and alveoli. In the alveoli, gas exchange occurs through diffusion as oxygen moves from the alveoli into the blood and carbon dioxide moves out. Smoking damages the lungs by paralyzing cilia and increasing risk of cancer and emphysema. Cystic fibrosis affects lung health by causing thick, sticky muc
Comparative Anatomy & Physiology of Respiration in Non chordata.pptx
1) Respiration in non-chordate animals occurs through diffusion or specialized respiratory organs depending on the species. Single-celled organisms rely on diffusion, while sponges also use diffusion and water circulation.
2) Invertebrates like worms, insects, and arthropods use structures like trachea, book lungs, and gills for respiration. Trachea are a branching tube system that deliver oxygen to insect tissues. Book lungs are found in some spiders and scorpions.
3) Molluscs generally use gills called ctenidia. Echinoderms rely on diffusion through tube feet extensions, while some develop dermal branchiae. Respiratory pigments like hemoglobin
Respiration system in insects
Insects breathe through a respiratory system consisting of spiracles, trachea, tracheoles, and air sacs. Air enters through openings called spiracles and travels through a network of tubes called trachea. The trachea branch into finer tracheoles where gas exchange occurs. Air sacs store oxygen and provide buoyancy. The respiratory system delivers oxygen to cells and removes carbon dioxide as a waste product, but is separate from the circulatory system.

This document discusses the respiratory organs and processes of various organisms. It states that cellular respiration is similar across organisms, but respiratory organs differ. Amoebas respire through their cell membranes, earthworms through skin with many blood vessels, cockroaches through a tracheal network, scorpions through book lungs, fish through gills, frogs through skin, mouth and lungs, and tadpoles through gills as larvae. The complexity of respiratory organs increases with organism complexity, while cellular respiration remains similar.
Bio 22 Lab Respiratory System
Respiration involves the diffusion of gases through membranes to facilitate metabolic processes in organisms. Simple organisms rely on direct diffusion through their integument, while more complex animals have respiratory systems. Aquatic animals use gills and many land animals use lungs. Amphibians are unique in that they can respire through their skin, mouth, and lungs. Their respiratory system includes glottis, larynx, bronchi and lungs, with gas exchange aided by a moist, permeable membrane.
Respiration And Gas Exchange
This document discusses cellular respiration and gas exchange in humans. It explains that aerobic respiration uses oxygen to break down glucose and release energy in the mitochondria, while anaerobic respiration can break down glucose without oxygen, but is less efficient. During exercise, muscles switch to anaerobic respiration when oxygen demands outpace supply. After exercise, breathing and heart rates remain elevated to transport oxygen for breaking down lactic acid buildup via aerobic respiration, paying back an "oxygen debt." Gas exchange occurs in the alveoli of the lungs, where oxygen diffuses into blood and carbon dioxide diffuses out through thin alveolar walls with a large surface area.

It provides details on the human respiratory system, including the pathways of oxygen and carbon dioxide in the nose, trachea, bronchi, bronchioles and alveoli. It also outlines the process of gas exchange that occurs between the lungs, blood,
Presentation on Organ & Mechanism of Respiration in Pisces And Amphibians
The document discusses the respiratory systems of various organisms. It describes how fish breathe through gills, with water passing over the gill filaments where gas exchange occurs. Amphibians may breathe through gills, lungs, or skin depending on their life stage, with tadpoles using external gills and adult frogs using lungs. The lungs of amphibians are relatively simple sacs that undergo positive pressure breathing by changing the mouth's volume and pressure.
The respiratory system
Respiration is the process by which organisms break down glucose to release energy in the form of ATP. It can occur aerobically, using oxygen, or anaerobically without oxygen. Aerobic respiration generates more ATP but requires oxygen delivered via the respiratory system. The human respiratory system involves the nasal cavity, pharynx, larynx, trachea, bronchi, bronchioles and alveoli where gas exchange occurs. Breathing is the process of inhaling and exhaling that delivers oxygen for aerobic respiration and removes carbon dioxide.
Ch 8 respiration 2019
The respiratory system takes in oxygen and releases carbon dioxide, with aerobic respiration using oxygen and anaerobic respiration not requiring oxygen. Cells use the energy released from respiration for functions like muscle contraction, maintaining temperature, and building molecules, with the lungs exchanging gases through thin-walled alveoli to test samples for carbon dioxide production and heat release as signs of respiration.
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.

LAND USE LAND COVER AND NDVI OF MIRZAPUR DISTRICT, UP
This Dissertation explores the particular circumstances of Mirzapur, a region located in the
core of India. Mirzapur, with its varied terrains and abundant biodiversity, offers an optimal
environment for investigating the changes in vegetation cover dynamics. Our study utilizes
advanced technologies such as GIS (Geographic Information Systems) and Remote sensing to
analyze the transformations that have taken place over the course of a decade.
The complex relationship between human activities and the environment has been the focus
of extensive research and worry. As the global community grapples with swift urbanization,
population expansion, and economic progress, the effects on natural ecosystems are becoming
more evident. A crucial element of this impact is the alteration of vegetation cover, which plays a
significant role in maintaining the ecological equilibrium of our planet.Land serves as the foundation for all human activities and provides the necessary materials for
these activities. As the most crucial natural resource, its utilization by humans results in different
'Land uses,' which are determined by both human activities and the physical characteristics of the
land.
The utilization of land is impacted by human needs and environmental factors. In countries
like India, rapid population growth and the emphasis on extensive resource exploitation can lead
to significant land degradation, adversely affecting the region's land cover.
Therefore, human intervention has significantly influenced land use patterns over many
centuries, evolving its structure over time and space. In the present era, these changes have
accelerated due to factors such as agriculture and urbanization. Information regarding land use and
cover is essential for various planning and management tasks related to the Earth's surface,
providing crucial environmental data for scientific, resource management, policy purposes, and
diverse human activities.
Accurate understanding of land use and cover is imperative for the development planning
of any area. Consequently, a wide range of professionals, including earth system scientists, land
and water managers, and urban planners, are interested in obtaining data on land use and cover
changes, conversion trends, and other related patterns. The spatial dimensions of land use and
cover support policymakers and scientists in making well-informed decisions, as alterations in
these patterns indicate shifts in economic and social conditions. Monitoring such changes with the
help of Advanced technologies like Remote Sensing and Geographic Information Systems is
crucial for coordinated efforts across different administrative levels. Advanced technologies like
Remote Sensing and Geographic Information Systems
9
Changes in vegetation cover refer to variations in the distribution, composition, and overall
structure of plant communities across different temporal and spatial scales. These changes can
occur natural.
