Respiratory System by Mind Map: Respiratory System

1. Mamals

1.1. how do they breathe

1.1.1. Most mammals have two lungs and a diaphragm that work together to allow one to breath. The diaphragm pulls the lungs down and sucks the air( Nitrogen ,Oxygen Carbon Dioxide,water vapour) in. Then, the diaphragm push the lungs up and lets the air out.

1.2. what are their respiratotry system made up of

1.2.1. tracheal,lung ,diaphragm,,Bronchi,Bronchioles

3. Animals

3.1. Amphibians

3.1.1. how do they breathe

3.1.1.1. Amphibians have three ways of breathing. The first is with gills, seen on tadpoles and salamanders that do not leave the water. The second is by diffusion through their skin. The third is with lungs, but they are primitive like lungfish and mudskippers.

3.1.2. what are their respiratory system made up of

3.1.2.1. lungs and skins

3.2. insects

3.2.1. how do they breathe

3.2.1.1. Insects breathe via holes in their exoskeleton called spiracles. These are normally arranged in pairs, with one spiracle either side of the thorax, or each segment of their bodies. They do not have lungs - gasses are passively exchanged throughout a network of capillaries (called trachea) that branch into their organs and tissues. Some larger insects are able to pump their bodies to increase the rate of gas exchange, therefore, in a way, actively 'breathing' in a manner akin to you.

3.2.2. what are their respiratory system made up of

3.2.2.1. spiracles

3.3. Reptiles

3.3.1. how do they breaths

3.3.1.1. All reptiles breathe through lungs. They breathe by means of muscles between ribs and stomach muscles.

3.3.2. what are their respiratory system made up of

3.3.2.1. Both the lungs and the skin serve as respiratory organs

3.4. Birds

3.4.1. how do they breathe

3.4.1.1. The external respiration system uses the lungs and a much larger series of air sacs distributed throughout the body so that the oxygen supply communicates directly with body parts. Oxygen is taken in and exchanged for carbon dioxide waste in the blood, then the carbon dioxide is moved out. in birds, the air flow is one way, through tubes and chambers,when a bird inhales, air actually leaves its lungs; fresh air enters the lungs as it exhales. First, a constant stream of air enters through the back of the mouth and goes into the trachea. It is channeled in a pair of tubes straight through the lungs and into the system of air sacs and hollow bones. Gases from the air sacs are sent forward through the lungs again, then through more air sacs into the trachea, and then finally expelled from the body.

3.4.2. what are their respiratory system made up of

3.4.2.1. Three distinct sets of organs perform respiration — the anterior air sacs, the lungs, and the posterior air sacs

3.5. Fish

3.5.1. how do they breathe

3.5.1.1. Breathe disolved air.Fish breathe by drinking. A pressurized gulp of water flows from the mouth into a gill chamber on each side of the head. Gills themselves, located in gill clefts within the gill chambers, consist of fleshy, sheetlike filaments As water flows across the gills, the oxygen within them diffuses into blood circulating through vessels in the filaments Simultaneously, carbon dioxide in the fish's bloodstream diffuses into the water and is carried out of the body

3.5.2. what are their respiratory system made up of

3.5.2.1. In most fish, respiration takes place through gills

4. Plants

4.1. how do they respire

4.1.1. Plants do not breathe although they respire. This is when they absorb oxygen from the air around them and in return, release Carbon Dioxide. This is different from photosynthesis where they release oxygen and take in carbon dioxide. They photosynthesise to produce glucose, and then respire to convert that glucose into energy. During the day, plants give out more oxygen, and during the night, plants give out more carbon dioxide.

4.2. what are their respiratory system made up of

4.2.1. stomata,stem
