This activity contains 12 questions.
Which of the following organisms has an open circulatory system?
Which of the following components is not found in all circulatory systems?
A cavity within the body that allows organs to be bathed directly in blood
A "heart" that pumps fluid throughout the body
A network of blood vessels through which blood travels to all parts of the body
Which of the following statements best describes "deoxygenated" blood?
It has gained oxygen after passing through the body's tissues.
It has gained oxygen after passing through the heart.
It has lost some of its oxygen to the body's tissues.
It has lost some of its oxygen after passing through the lungs or gills.
Which of the following statements about blood circulation in fish is true?
Blood enters the heart ventricle and then is pumped to the atrium.
Valves in the heart prevent blood from entering more than one chamber at a time.
The chambers of the fish heart contract simultaneously.
Oxygen-rich blood is transported from the gills to the heart, which then pumps the blood to the body's cells.
Which of the following statements about blood circulation in frogs is true?
Two arteries carry blood away from the heart to the pulmocutaneous circuit and to the systemic circuit.
Deoxygenated blood from the body enters the heart through the left atrium.
The frog heart consists of two ventricles and one atrium
Both oxygen-rich and oxygen-poor blood mix to some degree in the ventricle.
Which artery supplies the frog's head with oxygenated blood?
Which of the following statements best describes the function of the left ventricle?
It pumps deoxygenated blood to the lungs via the pulmonary circulation.
It collects deoxygenated blood from the lungs.
It pumps oxygenated blood around the body via the systemic circulation.
It collects oxygenated blood from the lungs.
Which of the following statements about blood circulation in humans is true?
During one cardiac cycle, the two ventricles contract first, and then the two atria contract.
Deoxygenated blood flowing through the pulmonary veins is carried to the right atrium.
As the right ventricle contracts, it sends oxygenated blood through the aorta to all tissues of the body.
Valves prevent the backflow of blood into the atria and ventricles.
True or false. In frogs, blood flows through the pulmocutaneous circuit between the heart and the lungs and skin and through the systemic circuit between the heart and the rest of the body.
True or false. Both open and closed circulatory systems are involved in the transport of blood, nutrients and respiratory gases to and from internal organs and tissues.
True or false. At the systemic capillary beds in fish, oxygen is released to the cells, which pass carbon dioxide to the blood; this carbon dioxide will eventually be released from the fish at the gill capillary bed.
True or false. The circulatory system of humans is composed of two loops: the systemic circulation, in which blood flows between the heart and lungs, and the pulmonary circulation, in which blood flows between the heart and the rest of the body.
