cardiovascular system Flashcards

1
Q
  1. what are the events, in order, of blood flow?
A

the valve between the atria and ventricles close, blood is pushed out from the right ventricle, then the left atrium fills with blood (discovery stations-cardiovascular system: station 5)

Q
  1. what are the functions of the cardiovascular system?
A

controlling many body processes by means of chemicals, carrying waste products away from cells, transporting cells that attack disease-causing microorganisms, and carrying oxygen, glucose, and other needed materials to cells (cardiovascular system notes page 10)

17
Q
  1. what is the blood type of a person whose plasma contains no clumping proteins?
A

type AB (concept 1 notes-blood page 5)

18
Q
  1. if you’re a doctor treating a patient with liver failure due to chronic alcoholism, on e of the results of this is reduced synthesis of plasma proteins, like fibrin. what issue can you expect to arise because of this?
A

an issue with coagulation of blood during blood clot formation (concept 1 notes-blood page 4)

19
Q
  1. define hematopoiesis. then describe the roles of two other organ systems in this process
A

blood cell formation. it occurs in the red bone marrow (skeletal system) and is regulated by a hormone called EPO (endocrine system) (concept 1 notes-blood page 4)

20
Q
  1. describe three factors that cause resistance to the flow of blood through the vessels. which has the greatest impact and why?
A

blood’s viscosity (thicker the blood, the greater the resistance), the length of a blood vessel (longer makes more resistance), and the diameter (smaller makes more resistance) of a blood vessel. the diameter of a blood vessel has the greatest impact because the viscosity of blood and the length of a blood vessel remain relatively constant, whereas the diameter of a blood vessel can change if the vessel contracts or is blocked in someway (like a build up of cholesterol!) (discovery stations-cardiovascular system: station 1)

21
Q

71b. assume you are blood type A, what antibodies do you have in your plasma?

A

anti-B antibodies (concept 1 notes-blood page 5)

22
Q

71d. assume you are blood type A, who can you donate blood to and why?

A

type A can donate blood to other people with type A and type AB because those people do not make anti-A antibodies and thus wouldn’t see the donated blood as foreign (concept 1 notes-blood page 5)

23
Q
  1. describe the pathway that blood will travel though each part of the heart. start with where oxygen poor blood enters the heart and end with where oxygen rich blood leaves the heart to head out to tissues in the body
A

oxygen-poor blood enters the heart through the superior vena cavas. it goes through he right atrium and then the tricuspid valve into the right ventricle. it passes through the pulmonary valve into the pulmonary trunk and out to the lungs to be oxygenated. it returns to the heart via the pulmonary veins and enters the left atrium. it goes through the mitral valve into the left ventricle and then is pumped through the aortic valve and out the aorta to the rest of the body (discovery stations-cardiovascular system: stations 4+5)

24
Q

73b. regarding the aorta, is the blood oxygenated or deoxygenated and where is it going next?

A

the blood is oxygenated, then it goes out to the rest of the body (discovery stations-cardiovascular system: station 5)

25
Q

73c. regarding the left pulmonary veins, is the blood oxygenated or deoxygenated? where is it going next?

A

the blood is oxygenated, then goes back to the heart (discovery stations-cardiovascular system: station 5)

26
Q

73d. regarding the pulmonary trunk, is the blood oxygenated or deoxygenated? where is it going next?

A

deoxygenated and then goes through the pulmonary arteries and travels to the lungs to be oxygenated (discovery stations-cardiovascular system: station 5)

27
Q

73e. regarding the tricuspid valve, is the blood oxygenated or deoxygenated? where is it going next?

A

deoxygenated and the blood goes into the right ventricle (discovery stations-cardiovascular system: station 5)
