The Body's Transport System Blood and Lymph Cardiovascular Disease Lots of Important Stuff
100
Tricuspid Valva
What is the flap of tissue that prevents blood from flowing backward from the venticle to the atrium?
100
Pacemaker
What is the group of cells called that send out signals to make the heart muscle contract?
100
Plasma, 90%
What is the liquid part of the blood called? What percentage is water?
100
A condition in which the artery wall thickens as a result of the build up of fatty materials.
What is atherosclerosis?
100
O
What is the universal donor blood type?
200
Carries needed substances to cells,
Carries waste away from cells
Contains cells that fight disease.
What are the three functions of the cardiovascular system?
200
Arteries, veins, and capillaries.
Name the three types of blood vessels
200
Hemoglobin; Found in red blood cells
What is the iron containing compound to which oxygen can chemically combine? Where is it found?
200
A heart attack occurs then blood flow to part of the heart muscle is blocked. Cells die in the part of the heart that does not receive blood and oxygen. This permanently damages the heart.
What is a heart attack?
200
AB
What is the universal recipient blood type?
300
Left and right ventricles, left and right atria. Septum
Name the four chambers of the heart. What is the wall of tissue that separates the sides of the heart?
300
Materials are exchanged between the blood and the body's cells.
What happens in the capillaries?
300
The lymphatic system is a network of veinlike vessels that returns fluid to the bloodstream.
What is the function of the lymphatic system?
300
A discorder in which a person's blood pressure is consistently higher than normal. It is called the silent killer b/c there are no obvious symptoms to warm them of the danger until damage is severe.
What is hypertension? Why is it called the silent killer?
300
The CO will bind to the hemoglobin where the O2 is supposed to bind. The blood will not be able to carry enough O2.
How does carbon monoxide cause a health issue?
400
Aorta
What is the largest artery?
400
Innermost layer is epithelial cells. Middle layer is muscle. Outer layer is flexible connective tissue.
Describe the three layers of the arteries.
400
Platelets collect and stick to the site of the wound. Platelets start a chemical reaction which forms the protein, fibrin. Fibrin traps platelets and blood cells, forming a clot (scab).
Describe what happens when you cut your arm.
400
Exercise regularly, eat a healthy diet, and do not smoke.
What are three things you can do to stay healthy?
400
Valves, contraction of skeletal muscles and breathing movements force blood toward the heart.
How does the blood continue to move toward the heart when it is in the veins?
500
Loop 1: O2 poor blood from body enters right artium and moves into right ventricle, The right ventricle pumps the blood toward the lungs, The O2 rich blood heads back to the heart.
Loop 2: the O2 rich blood enters the left artium and moves to the left ventricle. The left ventricle pumps the blood out to the body.
Describe the two loops in the cardivascular system.
500
Coronary Arteries
What are the blood vessels that supply blood to the heart itself
500
Plasma, Platelets, Red Blood Cells, White Blood Cells
What are the four components of blood?
500
The farther away from the ventricle the blood moves, the lower the force pushing it.
Why is blood pressure lower in the leg veins than in the aorta?
500
Blood pressure is caused by the force with which the ventricles contract.
What causes blood pressure?
