Chapter 23, Problem 8TYK
Which of the following is not a true statement about open and closed circulatory systems?
a. Both systems have some sort of a heart that pumps a circulatory fluid through the body.
b. A frog has an open circulatory system; other vertebrates have closed circulatory systems.
c. The blood and interstitial fluid are separate in a closed system but are indistinguishable in an open system.
d. Some of the circulation of blood in both systems results from body movements.

Many objects designed by engineers have “circulatory systems” of one type or another. Describe at least three or four examples. Why do engineers sometimes include systems of flowing fluids in objects they design? We often hear it said that animal systems can teach us how to design engineered systems. If you were a biologist teaching a group of engineers about the lessons of animal circulatory systems, what principles would you emphasize?
Which of the following statements about vertebrate circulatory systems is not true?
A.
In mammals, the blood pressure in the aorta is higher than the pressure in the pulmonary artery.
B.
In fishes, oxygenated blood from the gills returns directly to the heart through the left atrium.
C.
In birds, deoxygenated blood leaves the heart through the pulmonary artery.
D.
In reptiles, the blood in the pulmonary artery has a lower oxygen content than the blood in the aorta.
E.
In amphibians, deoxygenated blood enters the heart through the right atrium.
A typical circulatory system consists of
a.
a fluid and a series of conduits only.
b.
a muscular pump only.
c.
blood and blood vessels only.
d.
a muscular pump, a fluid, and a series of conduits.

- Which of the following is the best description of what happens in capillaries? A. Capillaries are surrounded by thicker smooth muscle moving blood cells to exchange nutrients and oxygen. B. Capillaries connect minor veins to major veins returning blood to the heart. C. Capillaries are the location where oxygen, carbon dioxide, and nutrients are exchanged with tissues at the cellular level. D. Capillaries are the site where blood mixes with interstitial fluid to allow for gas and nutrient exchange.arrow_forwardThe difference between the amphibian and mammal hearts is thata. in the amphibian heart, oxygenated and deoxygenated blood mix completely in the single ventricle.b. in the amphibian heart, there are two SA nodes so that contractions occur simultaneously throughout the heart.c. in the ventricle in the amphibian heart, internal channels reduce mixing of blood.d. in the amphibian heart, only the left aorta pumps oxygen obtained by diffusion through the skinarrow_forwardFigure 16.10 Which of the following statements about the circulatory system is false?a. Blood in the pulmonary vein is deoxygenated.b. Blood in the inferior vena cava is deoxygenated.c. Blood in the pulmonary artery is deoxygenated.d. Blood in the aorta is oxygenated.arrow_forward
- Hearts of mammals are described to have double pump structure. Which choice explains the functional and structural basis for the said description? A. Blood enters the atrium and pumped into ventricle. B. Blood pressure alternates between systolic and diastolic at all times. C. Atrium provide 1 pump, ventricle provides 2nd pump. D. Heart pumps blood simultaneously in systemic and pulmonary circuit.arrow_forwardWhat is the advantage of a four-chambered heart?a. It uses the least energy of any type of heart.b. It maximizes the amount of O2 reaching tissues.c. It enhances the mixing of blood from the pulmonary and systemiccirculation.d. Both a and c are correctarrow_forwardWhich of the following is/are true of a circulatory system (=fluid-transport system): A. aids diffusion by reducing functional diffusion distances B. transports substances rapidly between distant cells/tissues. C. is an adaptation to large body size. D. All of the abovearrow_forward
- Which of the following is a predicted outcome in a mammal heart that entirely lacks valves? A. Oxygenated and spent (deoxygenated) blood would mix. B. Cardiac output would be lower than that in a normal heart with valves. C. Heart rate would be lower compared with that in a normal heart with valves. D. A-V delay would be longer compared with that in a normal heart with valves. E. The pathways for blood flow to the body and the lungs would be reversed.arrow_forwardIn humans the wall of the left ventricle is thicker than that of the right ventricle. This adaptation is due to the fact that the left ventricle Select one: O a. pumps blood to the extremities of the body O b. pumps blood that is low in oxygen content O C. is smaller than the right ventricle O d. pumps blood to the left and right lungsarrow_forwardWhich of the choices below best describes the systemic circulation of blood?a. The flow of blood into the right atrium and eventually out of the left ventricle.b. The movement of blood from the pulmonary trunk, through capillaries into the pulmonary veins.c. The movement of blood into the coronary arteries, through capillaries into the coronary sinus.d. The movement of blood from the aorta, through arteries and capillaries and then eventually to the vena cavae.arrow_forward

All of these are correct.c. hemolympharrow_forwardnote whether the statements below are consistent with an open or closed circulatory system. The circulating fluid flows in one direction (unidirectionally) through a circulatory loop. The circulating fluid is called hemolymph. Ostia are pores in the heart, important for circulatory function. The circulating fluid is called blood. The circulating fluid remains in vessels as it moves throughout the organism. Is the more efficient type of circulatory system.arrow_forward
