Animals with open circulatory systems utilize a fluid called_______ that serves the function of both blood and_______ fluid. This fluid is passed among chambers in the body that are collectively calledthe_________ .
In insects, as in some other animals we have seen, the hemocoel is primarily responsible for: providing a place for food storage retracting the gubernaculum and the pharynx O coeling the hemo replacing the intestinal system with increased surface area holding and circulating body fluids protecting the anterior ganglia
The human circulatory system isclosed—that is, the blood pumped out of the left ventricle of the heartinto the arteries is constrained to a series of continuous, branching vesselsas it passes through the capillaries and then into the veins as it returnsto the heart. The blood in each of the heart’s four chambers comesbriefly to rest before it is ejected by contraction of the heart muscle. The velocity of blood in the aorta can be measured directly with ultrasound techniques. A typical graph of blood velocity versus time during a single heartbeat is shown in Fig. . Which statement is the best interpretation of this graph? (a) The blood flow changes direction at about 0.25 s; (b) the speed of the blood flow begins to decrease at about 0.10 s; (c) the acceleration of the blood is greatest in magnitude at about 0.25 s; (d) the acceleration of the blood is greatest in magnitude at about 0.10 s.
Three circulatory systems of vertebrates are represented in the following diagram. Identify to which group of animals each circulatory system belongs and mention the reasons for considering them as such. ↑ Capilares de las branquias Aorta Capilares sanguíneos ↓ Capilares pulmonares Aorta Capilares sanguíneos ↓ Capilares pulmonares Aorta Capilares sanguineos
Neither cnidarians nor turbellarians possess a circulatory system. For most large, active animals, this would pose a (fatal) problem. Describe and discuss the features of large active cnidarians ands turbellarians that allow them to respire, nourish their cells, and excrete despite the absence of a conventional circulatory system.

Figure 39.7 Which of the following statements about the mammalian respiratory system is false? When we breathe in, air travels from the pharynx to the trachea. The bronchioles branch into bronchi. Alveolar ducts connect to alveolar sacs. Gas exchange between the lung and blood takes place in the alveolus.

At the venous end of a capillary: O a. The blood pressure equals the osmotic pressure. O b. All the plasma that was lost at the arteriole end is recovered back into the blood. Oc Glucose enters the blood. O d. Carbon dioxide enters the blood. O e. The blood pressure is higher than the osmotic pressure. Monotremes are very primitive mammals because:
