Circulation Systems on Animal

Circulation Systems on Animal For Protozoa And a number Metazoa low behavior , like Porifera, And Planaria circulation of substances in all over his body through process diffusion, osmosis, And transport active. Circulation system just going on in in cell or intercell just, nothing _ circulation system Which special. Circulation system on Planaria Act also as system excretion Which branching to all over part body And gather substances _ waste Which must issued from body. Worm land have system blood transport closed. Wall vessels blood very thin, And substances can diffuse with easily between blood and extra cellular fluid. Blood vessels consist of the dorsal veins , vessels blood stomach, And five install arch aorta Which works as heart. Blood in in vessels blood back flowing from behind going to head. From vessels back blood blood flow going to vessels stomach blood through curved aorta Which located in the front. In vessels stomach, blood flow from the front going to behind. Circulatory system in insects, for example grasshoppers only consists from One vessels Which Insect own system circulation blood open, blood circulated from aorta to all over body without through vessels blood. Blood from all over body enter to the heart through system osteum And No own vessels come back.Other case with animals Which have level more tall, circulation in in his body happen from One part body to part body Which other so no adequate Again If only depend on process diffusion. Animals is equipped with system circulation blood Which can grouped become two kinds, that is system circulation blood open And system circulation blood closed . Open Blood Circulation System On system This, blood mixed with fluid Which there is on cavities _ body nor on spaces internetwork. Blood on system bloodcirculation open generally almost No colored although contain respiratory pigment form hemoglobin, hemocyanin, or type other Which dissolved in inside. Cells blood nature amoeboid. Animals that have an open circulatory system include Arthropods as well as part from annelids, mollusca, And echinoderms. Genre blood in in body animal the caused by insistence from heart Which the structure is still very simple, for example on mollusca only consists from One porch (atrium) And One room (ventricles). Heart on a number of type Arthropods don't have rooms so that considered as widening vessels blood just. (a) (b) Picture 1. ( a ) Open blood circulation system ( b). Closed blood circulation system Closed Blood Circulation System This circulatory system is found in chordates, cephalopods, holothuroidea, oligochaeta, and hirudinae. However, the discussion will focus more on vertebrates Which is member from chordates. Tool its circulation consists from blood, heart, And vessels blood. Heart works as tool pumper blood. Composed on porch (the chamber that holds blood and the chamber (the blood pump that causes Genre blood to outside heart). Second type room the separated by valve deterrent current come back. Form And arrangement heart on animals vertebrates There is a number of kind of dependent on the level. Picture 2. Arrangement heart on a number of vertebrates. Closed blood circulation can differentiated become circulation single blood and double blood circulation. a. Blood Single Circulation Single blood circulation , there is on fish. Blood from room all pumped in one direction through cone arteriousus then to aorta ventralis Which towards the gills For release CO2 and binding O2. furthermore blood streamed throughout _ part body through the arteries And its branches relate with vessels capilary. Then, blood will collected into vena cava and going to sine venous and ends in porch to continued in the room. So, blood only pass on heart once. That’s why, its called single blood circulation. b. Double blood circulation Circulation blood double, that is part blood And room will traverse pulmonary entering the heart) circulation. On circulation arteries pulmonary, after it happened exchange gas, so blood which contains a lot of oxygen will return to the heart via the pulmonary veins to porch left And forwarded to room. On circulation systemic, blood and booth streamed through aorta (pulse big) which is later branching become artery to all over part body And followed by capillaries. After the exchange occurs substances between blood in in capillaries with fluid network so blood contains lots of CO 2 collected vein then continued to vein cava.
