Which organ pumps blood through blood vessels?
The heart
100
Which types of blood cells destroy pathogens, clean wounds, and provide a mobile defense force against pathogens?
White Blood Cells
100
Pulmonary embolism is the blocking of the major artery (or any of the branching blood vessels) of which major organ?
The lung
100
If a blood vessel is opened, the _______ clump together by the opening to block it up and release chemicals that react with the _______ in the blood. The reaction causes tiny fibers to form a blood clot.
Platelets; plasma
200
What are the two types of blood cells?
Red blood cells and white blood cells
200
What is the fluid part of blood?
Plasma
200
What is the main job of capillaries?
Capillaries exchange nutrients, oxygen, and other substances from blood to cells and waste from cells to blood.
200
List three risk factors for pulmonary embolism.
Inactivity Dehydration Age (over 40) Pregnancy Hospitalization Heart attack Obesity Prior clots Defective clotting gene
200
To which side of the center of the chest cavity is the heart located?
The heart is located slightly to the left of the center chest cavity.
300
_____________ are blood vessels that carry blood to the heart. Hint: 5 letters
Veins
300
The heart ______________ rhythmically to keep ________ coursing through the arteries and veins.
Contracts; blood
300
Name two types of white blood cells OR Name one type of white blood cell and how it completes its job.

300
Answer one of the following questions: What is a possible cause of a heart attack? OR What does the result depend on?
Possible Causes: Progressive coronary artery disease Coronary arteries are blocked and not enough oxygen reaches the heart Result Depends On: Location of blockage (left artery blockages are more serious than right artery blockages)
300
What color is plasma?

400
What are pathogens?
Pathogens are tiny living things that cause diseases.
400
What types of blood cells do red bone marrow produce?
Reed bone marrow produces both red and white blood cells.
400
What jobs do the left and right atriums have, respectively?
Oxygenated blood from lungs fills left atrium; deoxygenated blood from blood tissues fills the right atrium.
400
How would a person get sickle cell anemia?
Sickle cell anemia is hereditary, and both parents must have the sickle cell trait for it to be passed on (however, some people with the trait do not have the actual disease)
400
What is the connection between the circulatory system and bones?
Blood cells mature in the bone marrow.
500
What type of blood vessels do arteries become as they get smaller and narrower?
Arteries become capillaries as they become smaller and narrower.
500
What are platelets? Where and how are they formed? (All three questions MUST be answered for points)
Platelets – tiny particles drifting among blood cells; pieces of larger cells in bone marrow that are pinched off and enter the bloodstream
500
What do red blood cells do?
Red blood cells carry oxygen to the cells in the body and contain hemoglobin (an oxygen-carrying protein)
500
How can pulmonary embolism cause sudden death? Give an example of a situation in which a person could die from this health problem.
When the clot reaches the lung, it cuts off arteries that usually carry oxygen and can cause heart failure. Example: 50 year old John was on an 18 hour flight, and he stayed in his seat for the entire time. A clot in his leg traveled through his bloodstream to his lung, where it blocked oxygen from getting to the rest of his body. He died before reaching the hospital.
