The vertebrate circulatory system Britannica.com. Besides the basic chordate characters, vertebrates have a ventral muscular heart with two, three or four chambers, kidneys for excretion and osmoregulation and paired appendages which may be fins or limbs., In modern lampreys, the heart is composed of four chambers: a sinus venosus, atrium, ventricle, and truncus arteriosus (the truncus arteriosus is also referred to as the conus arteriosus or the bulbis cordis)..

The evidence that sea lamprey eggs can develop successfully only within a limited temperature range suggests that unfavorable temperatures may account for the failure of certain apparently suitable streams to produce larval lampreys. intact, we investigated mechanical interactions between the four heart chambers from the standpoint of ventricular pressure-volume relationships.

The lamprey heart has two chambers, with components that include neural crest-derived elements in jawed vertebrates. Embryonic lamprey hearts have been reported to have multiple valves, including a sinoatrial valve, an atrioventricular valve, and outflow valves ( Farrell, 2007 ; Lee et al., 2013 ; Richardson et al., 2010 ; Shipley ). Transgenic technology has potentially solved many of the immunological difficulties of using pig organs to support life in the human recipient.

Summary The heart is an organ that pumps blood by creating positive and negative pressures at a regular rhythm. Vertebrates improved the pump design by creating cardiac chambers, while acces- sory pumps that are present in many species, such as hagfish, remained redundant. However, the process by which the blood circulatory system develops in vertebrates, including the development of the heart 2 Vertebrates. Four extant groups of verte-brates. 1. Agnatha – jawless fish. 2. Chondrichthyes – sharks and rays (cartilaginous). 3. Osteichthyes – bony fish.

1.1 Basic Function of the Heart: The heart has 4 chambers that act together to pump blood throughout the body. The 2 smaller upper chambers are called atria, and the larger lower chambers are called ventricles. The right atrium receives oxygen-depleted blood coming back from the body via 2 large veins: the superior vena cava and inferior vena cava. The right atrium pumps this blood into the Evolution of the Vertebrate Heart Two Chambers: Two Chambers plus Septa: Three Chambers: Four Chambers: Human Heart Anterior and Posterior Vena Cava

While the primary heart tube is growing by addition of cells, it does not show significant cell proliferation, until chamber differentiation and expansion starts locally in the tube, by which the

Thus, inflow and outflow patterning of the heart field may set the stage for ballooning, or additional mechanisms, to form, in a species-specific fashion, chambers from the four original vertebrate cardiac compartments, SV, atrium, ventricle and conus arteriosus. The four chambers of the heart (sinus venosus, atrium, ventricle and conus arteriosus) are separated by valves, each of which has a pair of leaflets which open and close. The junctions of the left anterior and posterior cardinal veins and of the right anterior and posterior cardinal veins are united transversely where they meet the right and left descending ducts of Cuvier. Since this allows

simple heart-like cells to those with complex four-chambered hearts, it has been theorized and proven that expansion of this regulatory network by adding new transcription factors is a major force for the heart to evolve new structures.1,2 How-ever, the addition of new transcription factors can only be a part of the mechanism underlying the formation of complex hearts.

The atria are the receiving vesicles, while the ventricles are the muscular pumps. The blood first enters the heart from the systemic circulation into the right atrium. From the right atrium it travels through the tricuspid valve and into the right ventricle. From the right ventricle it is moved

The body form of lampreys is simple and essentially the same as a 360 million year old fossil lamprey described by Gess et al. (2006).

They have well developed hearts with three or four chambers and have a closed circulatory system. There are 41700 species in eight different groups and they are as follows: Amphibia (frogs, salanders), Aves (birds), Cephalaspidomorph (lamprey), chondrichthyes (hag fish), osteichthyes (bony fish) and reptilian (crocodiles, snakes, turtles).
