• Reproductive System – the organs and tissues involved in reproduction, including gonads, eggs, sperm. • Respiratory System – organs and tissues involved in the oxygen & carbon dioxide gas exchange, including gills, gill rakers, and gill filaments. • Scales - protective cover on a fish; similar to skin. 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. 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. Dissection of the fish respiratory system. 1. The shape of the fish is observed: streamlined, neck less, paired fins and flexible tail 2. The advantage of having such shapes is found out. 3. Fish bodies are covered with scales. The function of the scales is found out. 4. Bony fishes have a movable operculum or gill -cover protecting the gills. Fish Respiration. Fish live in predominantly aquatic environments however there are exceptions, such as the lung fish which are able to utilise lungs to obtain oxygen. Aquatic fish however use a set of respiratory organs known as gills. Gills are highly vascularised with a large surface area, short diffusion distance and an always moist surface.

HUMAN RESPIRATORY SYSTEM. The human respiratory system is made up of many organs such as nose, nasal cavity, pharynx, larynx, trachea, bronchi and a pair of lungs. But, lungs are the main respiratory organs where exchange of gases takes place. Following is the detail of human respiratory system. 1. Nasal cavity Respiratory system dissection layer 1 View Related Images. Description: This is the first dissection stage of the respiratory system and it clearly demonstrates some of the major organs of this system. Beginning in the anterior neck, the larynx is clearly evident. Descending from the larynx into the mediastinum of the thorax is the trachea. The respiratory system in fish are responsible for moving oxygen from the outside environment into the body and removing CO2 and other wastes from the body. Even more (info 4 u), the fish has specialized structures within its body which allow this process to occur: First, the fish takes in water through it's mouth.

Bony Fish (Perch) Anatomy - Duration: 5:55. Fish Dissection! : What's in that fish on your dish? While we may be used to the simple tuna fish sandwich or of simply wondering what the heck our goldfish is thinking about, there's a tremendous amount we can learn by investigating the anatomy of a fish. If you've... An introduction to the biology of the anatomy of the digestive system of fish Fish anatomy 1: The Digestive Tract As with all animals digestion in fish involves the breakdown of eaten food into its smaller component parts, amino acids, vitamins, fatty acids etc. which can then be used to build up new fish body.

Feb 25, 2016 · Bony fish respire through a system that is known as a countercurrent system. Water enters through the mouth as the buccal cavity relaxes causing a pressure difference allowing water to flood into the mouth. Regardless of the environment they live in, all bony fishes have a respiratory system. Their respiratory system is used for exchanging gases (carbon dioxide and oxygen), just as it is in humans. Mar 13, 2015 · The respiratory system, which includes air passages, pulmonary vessels, the lungs, and breathing muscles, aids the body in the exchange of gases between the air and blood, and between the blood ... Lungfish have a highly specialized respiratory system. They have a distinct feature that their lungs are connected to the larynx and pharynx without a trachea. While other species of fish can breathe air using modified, vascularized gas bladders, these bladders are usually simple sacs, devoid of complex internal structure.

Students will work in small groups as they examine a variety of fish, study the internal and external anatomy, and learn how and why researchers collect fisheries-related data. Background In fish, this gas exchange occurs through gills. Some invertebrates, like cockroaches, have simple respiratory systems made of interconnecting tubules directly delivering oxygen to tissues. In humans and other mammals, there is an extensive, highly vascularized organ system specialized for gas exchange.

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. Mouth shape and tooth structure vary greatly in fishes, depending on the kind of food normally eaten. Most fishes are predacious, feeding on small invertebrates or other fishes and have simple conical teeth on the jaws, on at least ... Organisms like fish, which live in water, need oxygen to breathe so that their cells can maintain their living state. To perform their respiratory function, fish have specialized organs that help them inhale oxygen dissolved in water. Respiration in Fish. Respiration in fish takes with the help of gills. The Respiratory System. The primary function of the respiratory system is gas exchange between the external environment and an organism’s circulatory system. In humans and other mammals, this exchange balances oxygenation of the blood with the removal of carbon dioxide and other metabolic wastes from the circulation.

Beginning in the anterior neck, the larynx is clearly evident. Descending from the larynx into the mediastinum of the thorax is the trachea. This section provides the basic concepts of fish anatomy and physiology by organ systems, assisted by images and figures. NECROPSY The core of this manual, the external and internal examination procedures, with a strong visual support throughout will be found here. 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. In addition to respiration, in teleosts fish , the respiratory system has other functions such as osmoregulation, excretion of nitrogenous waste (ammonium), acid-base regulation and detoxification.
