- In arthropods the open circulatory system is the primary means by which cells receive oxygen for cellular respiration. True FalseLabel the parts of the CIRCULATORY SYSTEM found on the dorsal side of a cockroach.Describe the similarities and differences in the structure of the hearts of teleosrt fish, frogs, birds and rats.
- Compare and contrast the open circulatory system of anarthropod with the closed system of an annelid.What is a characteristic of the circulatory systems of arthropods and mollusks that distinguishes them from the circulatory system of echinoderms? They have lungs. They have muscular pumps to circulate the extracellular fluid. They are closed circulatory systems. They have extracellular fluid to transport substances to and from internal organs. They have cilia to circulate the extracellular fluid.What are some physiological reasons for the diversity of vertebrate circulatory systems?
- Describe the homeostatic functions of the vertebrate circulatory system. What function are maintained at relative stability?In sharks hormones regulate which of the following functions? Digestion Growth Stress responses Lactation The lymphatic system Smell Defecation Osmoregulation Reproduction Color change and bioluminescence Leckking behaviourA unique feature of the gastropods is that they undergo the process of embryonic torsion. This process results in; The spiral shaped shell that gastropods have The gastropod develops retractable antennae the anus being positioned near the head The gastropod foot becomes elongated and pliable
- Trace blood flow through the chambers and vessels of the frogs heart. Use red ink for oxygenated blood and blue ink for deoxygenated blood.Discuss why the frog's circulatory system is considered less efficient.Which sequence of blood flow can be observed in either a reptile or a mammal? right atrium → pulmonary artery → left atrium → ventricle left ventricle → aorta → lungs → systemic circulation right ventricle → pulmonary vein → pulmocutaneous circulation pulmonary vein → left atrium → ventricle → pulmonary circuit vena cava → right atrium → ventricle → pulmonary circuit
