Fish gill Most fish exchange gases using gills on either side of the pharynx (throat). Gills are tissues which consist of cloth and fabric structures called filaments. These filaments have many functions including the transfer of ions and water, as well as the exchange of oxygen, carbon dioxide, acids and ammonia.Each filament contains a capillary network that provides a large surface area for exchanging oxygen and carbon dioxide.he gills push the oxygen-poor water out through openings in the sides of the pharynx. Some fish, like sharks and lampreys, possess multiple gill openings. However, bony fish have a single gill opening on each side. This opening is hidden beneath a protective bony cover called an operculum.

- This similarity exists because water, ions, and small solutes are continuously exchanged between plasma and interstitial fluids across the walls of capillaries. Plasma, the major component in blood, communicates freely with interstitial fluid through pores and intercellular clefts in capillary endothelium.his similarity exists because water, ions, and small solutes are continuously exchanged between plasma and interstitial fluids across the walls of capillaries.

The Circulatory System of the Cnidaria Jellyfish do not have a specialized circulatory system, but they use diffusion as a way to circulate materials throughout their body. Almost every cell is in contact with the environment and so they are in direct contact with the nutrients and materials they need.

- Primary and secondary. It is important that we understand the design and normal structure of fish gills, so lets quickly review the anatomical features of this specialised organ. ‘Branchia’ in Greek means gills and in bony fish (teleosts) = the gills lie in a branchial cavity covered by the bony operculum (gill cover).chematic of the teleost fish gill. Secondary lamellae Retrieved from the World Wide Web (October 2012) http://www.biology-resources.com/drawing-fish-gill-filaments.html This is a close up diagram of the gill lamellae; you can see the long primary lamellae here and the secondary lamellae branching off.

- Microfilaments. The microfilament system is a network of filaments 6 nanometers (nm) in diameter that are important for anchoring plasma membrane proteins, for producing cell movement, and for cell division. The base filament is composed of a protein called actin that is 42 kilodaltons (kd) in weight.nlike the other systems, which are composed of one or two different proteins, intermediate filaments can be formed by a relatively large number of different proteins. For example, the primary intermediate filaments found in epithelial cells (such as skin) are formed from pairs of keratins, one basic and one acidic.

The blood vessels The microscopic capillary tubules consist of a single layer of endothelium that is a continuation of the innermost lining cells of arteries and veins. As the capillaries converge, small venules are formed whose function it is to collect blood from the capillary beds (i.e., the networks of capillaries).

Lymphatic Capillaries: Function & Explanation Mingled among the millions of blood capillaries throughout your body is another network of tiny, thin-walled vessels called lymphatic capillaries. The structure of a lymphatic capillary is similar to that of a blood capillary, but its function is distinctly different. Like a system of storm drains channeling rainwater from a city's streets, your lymphatic capillaries pick up the fluid that leaks into your tissues and help return it to your circulatory system.

Glomerulus (kidney) A glomerulus is a network (as a tuft) of capillaries located at the beginning of a nephron in the kidney. It serves as the first stage in the filtering process of the blood carried out by the nephron in its formation of urine.The glomerulus is surrounded by a cup-like sac known as Bowman's capsule.he glomerulus is a tuft of small blood vessels called capillaries located within Bowman's capsule within the kidney. Between the capillaries and Bowman's capsule lies mesangium. Blood enters the capillaries of the glomerulus by a single arteriole called an afferent arteriole and leaves by an efferent arteriole.

Capillary A capillary is a blood vessel. It does not have the muscular/elastic tissue of other blood vessels. It has a single celled wall to help substances be transported through organisms. Capillaries are small, and smaller than any other blood vessels.

Image: Fish Dissection - Gills exposed The gill filaments of bony fishes (also known as a primary lamellae) are complex structures which have a large surface area. Off each are numerous smaller secondary lamellae. Tiny blood capillaries flow through the secondary lamellae of each gill filament.The direction of blood flow is opposite to that of water flow.ill arches : Most fishes have gill arches. They are the boomerang-shaped bony or cartilaginous structures that support the gills. Each gill arch comprises an upper and a lower limb that are joined posteriorly. Attached to the gill arches are the gill filaments and gill rakers.

- Microfilaments are the thinnest fibers of the cytoskeleton. They are 7 nanometers in diameter. These fibers are composed of actin protein. Monomers of actin combine to form long double helical chains. Microfilaments share a lot of similarities with microtubule function.any different types of cells have a complex called the cytoskeleton, or network of thin fibers, that can help these cells do a range of activities. Maybe a cell can't pass around a pigskin, but it can do some equally cell-like, impressive things with the help of its very own skeleton.

Image: Fish Dissection - Gills exposed Notes. Gill filaments : Just like the lungs of humans, the gills of fishes are the sites where oxygen is absorbed and carbon dioxide is removed. In addition, the gills are responsible to a varying degree for regulation of the levels of various ions and the pH of the blood.he gill arches not only provide support for the gills but also their associated blood vessels. Arteries entering the gills (the afferent branchial arteries) contain blood that has a low concentration of oxygen and a high concentration of wastes.

Microcirculation The endothelium provides a smooth surface for the flow of blood and regulates the movement of water and dissolved materials in the interstitial plasma between the blood and the tissues. The endothelium also produces molecules that discourage the blood from clotting unless there is a leak.lood flows out of the capillaries into the venules, which have little smooth muscle and are 10-200 µm. The blood flows from the venules into the veins. In addition to these blood vessels, the microcirculation also includes lymphatic capillaries and collecting ducts.

Peritubular capillaries (May 2015) In the renal system, peritubular capillaries are tiny blood vessels, supplied by the efferent arteriole, that travel alongside nephrons allowing reabsorption and secretion between blood and the inner lumen of the nephron.

Understanding Capillary Fluid Exchange The flow of blood in the capillaries is controlled by structures called precapillary sphincters. These structures are located between arterioles and capillaries and contain muscle fibers that allow them to contract. When the sphincters are open, blood flows freely to the capillary beds of body tissue.When the sphincters are closed, blood is not allowed to flow through the capillary beds. Fluid exchange between the capillaries and the body tissues takes place at the capillary bed.apillaries measure in size from about 5-10 microns in diameter. Capillary walls are thin and are composed of endothelium (a type of simple squamous epithelial tissue). Oxygen, carbon dioxide, nutrients and wastes are exchanged through the thin walls of the capillaries.

Countercurrent multiplication Pump: The Na+/K+/2Cl− transporter in the ascending limb of the loop of Henle helps to create a gradient by shifting Na+ into the medullary interstitium. The thick ascending limb of the loop of Henle is the only part of the nephron lacking in aquaporin—a common transporter protein for water channels.
