Chapter 29

Question 1

If you were studying the type of blood which has an oxygen transporting pigment which has a copper-containing heme group, you would be studying which of the following?

A. hemoglobinB. hemothrombinC. hemocyaninD. chlorocruorinE. hemophil

Question 2

The circulatory fluid which is not found in blood vessels but flows into a body cavity or chamber is referred to as:

A. hemophil

B. hemolymph

C. plasma

D. hemoglobin

E. hemothrombin

Question 3

If a biologist is studying the circulatory system of a grasshopper, he or she would determine that it has a:

A. closed circulatory system

B. ostium circulatory system

C. cardia circulatory system

D. open circulatory system

E. capillary circulatory system

Question 4

The circulatory system would have all of the following functions except:

A. it takes oxygen to tissues

B. it takes waste away from tissues

C. it takes carbon monoxide away from tissues

D. it takes carbon dioxide away from tissues

E. it takes nutrients to tissues

Question 5

Of all of the following organisms, which has a true circulatory system?

A. arthropods

B. echinoderms

C. roundworms

D. cnidarians

E. flatworms

Question 6

If you were studying the type of circulatory system which has a heart and blood flows within vessels, you would be studying:

A. an open circulatory system

B. a cardiac circulatory system

C. a hemolymph circulatory system

D. a systemic circulatory system

E. a closed circulatory system

Question 7

Which of the following group of organisms has a single-loop circulatory pathway?

A. amphibians

B. birds

C. fish

D. reptiles

E. mammals

Question 8

Organisms which are endothermic and are very active, such as birds and mammals, would have which type of circulatory system?

A. a heart that has two chambers

B. a single-loop circulatory pathway

C. a circulatory system where oxygen rich and poor blood mix

D. a complete separation of the pulmonary and systemic circuits

E. a three-chambered heart

Question 9

Which blood vessels carry blood away from the heart?

A. capillaries

B. venules

C. veins

D. arteries

E. lymph vessels

Question 10

Which of the following is not a correct association?

A. arteries-have muscle linings and are deep in the body

B. capillaries-oxygen and nutrient exchange

C. arteries-high blood pressure

D. veins-high blood pressure and are deep in the body

E. veins-have valves to return blood to the heart

Question 11

"Artery" and "vein" are defined by whether they take blood away or toward the heart. If they were defined by whether they carry oxygenated or deoxygenated blood, we would have to change the name(s) of:

A. the hepatic portal vein to hepatic portal arteryB. the hepatic and renal systems, would have to be

switchedC. the pulmonary artery and vein would have to be

switchedD. the coronary artery and vein would have to be

switchedE. the aorta and vena cava would have to be switched

Question 12

What is the correct sequence a drop of blood returning from the body encounters in the heart chambers?

A. left atrium, left ventricle, right atrium, right ventricle

B. left ventricle, left atrium, right ventricle, right atrium

C. right atrium, left atrium, left ventricle, right ventricle

D. right atrium, left ventricle, left atrium, right ventricle

E. right atrium, right ventricle, left atrium, left ventricle

Question 13

Contraction of the right ventricle forces blood initially into the:

A. pulmonary artery

B. right atrium

C. aorta

D. pulmonary vein

E. left atrium

Question 14

If you were tracing the path of blood from the right to the left side of the heart, you must mention the:

A. aorta

B. hepatic portal vein

C. lungs

D. superior vena cava

E. inferior vena cava

Question 15

A biologist is studying the valve in the human heart which prevents blood from back flowing into the left ventricle. Based on this information you would conclude that he or she is studying which of the following valves?

A. bicuspid

B. pulmonary semilunar

C. vena cava

D. aortic semilunar

E. tricuspid

Question 16

Systole occurs when the:

A. heart tissue is contracting

B. heart tissue is relaxing

C. semilunar valves open and close

D. aortic valves open and close

E. atrioventricular valves open and close

Question 17

The alternating expansion and recoil of an arterial wall is termed a(n):

A. ECG

B. diastole

C. pulse

D. hypertension

E. heart murmur

Question 18

The "lub" heart sound is due to the:

A. onward rush of blood to the heart

B. contraction of the aortic muscle

C. closing of semilunar valves

D. the closing of the atrioventricular valves

E. the closing of both the semilunar and atrioventricular valves

Question 19

The pacemaker of the heart is termed the:

A. AV node

B. cardiac center in the medulla

C. SA node

D. vagus nerve

E. Purkinje fibers

Question 20

During a single heartbeat, first the ____________ contracts, and then the _____________ contracts.

A. SA node; AV node

B. ventricles; atria

C. AV node; SA node

D. SA node; ventricles

E. atria; ventricles
