the respiratory system in fish ppt


Respiratory System Organization Respiratory Mucosa • Respiratory epithelium plus supporting connective tissue with mucous glands • Lines nasal cavity and most of airways RESPIRATORYSYSTEM 2. Respiratory system - Respiratory system - Amphibians: The living amphibians (frogs, toads, salamanders, and caecilians) depend on aquatic respiration to a degree that varies with species, stage of development, temperature, and season. The Respiratory System 2. Respiratory system The function of the respiratory system is to enable gas exchange between the fish and the water, a process that is necessary for the vital functions to be performed. This helps a person breathe. Explain that the diaphragm is a muscle that moves up and down to expand the lungs. Respiratory System Anatomy and Physiology – Part 3. Ppt respiratory system- physiology 1. The Respiratory System 1. Mouth shape and tooth structure vary greatly in fishes, depending on the kind of food normally eaten. With the exception of a few frog species that lay eggs on land, all amphibians begin life as completely aquatic larvae. The gills lie behind and to the side of the mouth cavity and consist of fleshy filaments supported by the gill arches and filled with blood vessels, which give gills a bright red colour. Comparative Anatomy Respiratory System Note Set 10 Chapter 11 Respiratory System Gas exchange system Oxygen and carbon dioxide Fish- internal gills or lungs Some ... – A free PowerPoint PPT presentation (displayed as a Flash slide show) on PowerShow.com - id: 3d7b87-MDY1Y Oversees gas exchanges (oxygen and carbon dioxide) between the blood and external environment Exchange of gases takes place within the lungs in the alveoli (only site of gas exchange, other structures passageways Passageways to the lungs purify, warm, and humidify the incoming air Shares responsibility with cardiovascular system … Guided Practice (15 minutes) Chapter 22 Gas Exchange / Respiratory System 852719 PPT Presentation Summary : Respiratory structures such as gills, lungs, and insect tracheal systems are highly branched, reflecting an adaptation to increase the surface area and, As it goes further down, the trachea splits into two mainstem bronchi, one … PowerPoint ® Lecture Outlines ... Respiratory System Organization The Nose, Nasal Cavity, and Pharynx Figure 15-2. https://www.slideshare.net/alubajessabeth/respiratory-system-g6 Fish - Fish - The digestive system: The digestive system, in a functional sense, starts at the mouth, with the teeth used to capture prey or collect plant foods. Ok, are you on board so far? Introduction to the Respiratory System Expiration Largely a passive process which depends on natural lung elasticity As muscles relax, air is pushed out of the lungs ... – A free PowerPoint PPT presentation (displayed as a Flash slide show) on PowerShow.com - id: 52c637-NjExO Great. TWO DISTINCT OFRESPIRATION: Internal or cellular respiration:-refers to the intracellular metabolic processes carried out within the mitochondria, which use oxygen and produce carbon dioxide during derivation of energy from nutrient molecules. Fish - Fish - The respiratory system: Oxygen and carbon dioxide dissolve in water, and most fishes exchange dissolved oxygen and carbon dioxide in water by means of the gills. So, the next part of the respiratory system anatomy and physiology is the trachea, the windpipe. Remind them that the lung is the main part of the respiratory system and puts oxygen into the bloodstream.
