The Body's Transport System | Blood and Lymph | Cardiovascular Disease | Lots of Important Stuff | |
---|---|---|---|---|
Tricuspid Valva
What is the flap of tissue that prevents blood from flowing backward from the venticle to the atrium?
|
Pacemaker
What is the group of cells called that send out signals to make the heart muscle contract?
|
Plasma, 90%
What is the liquid part of the blood called? What percentage is water?
|
A condition in which the artery wall thickens as a result of the build up of fatty materials.
What is atherosclerosis?
|
O
What is the universal donor blood type?
|
Carries needed substances to cells,
Carries waste away from cells Contains cells that fight disease.
What are the three functions of the cardiovascular system?
|
Arteries, veins, and capillaries.
Name the three types of blood vessels
|
Hemoglobin; Found in red blood cells
What is the iron containing compound to which oxygen can chemically combine? Where is it found?
|
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?
|
AB
What is the universal recipient blood type?
|
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?
|
Materials are exchanged between the blood and the body's cells.
What happens in the capillaries?
|
The lymphatic system is a network of veinlike vessels that returns fluid to the bloodstream.
What is the function of the lymphatic system?
|
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?
|
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?
|
Aorta
What is the largest artery?
|
Innermost layer is epithelial cells. Middle layer is muscle. Outer layer is flexible connective tissue.
Describe the three layers of the arteries.
|
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.
|
Exercise regularly, eat a healthy diet, and do not smoke.
What are three things you can do to stay healthy?
|
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?
|
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.
|
Coronary Arteries
What are the blood vessels that supply blood to the heart itself
|
Plasma, Platelets, Red Blood Cells, White Blood Cells
What are the four components of blood?
|
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?
|
Blood pressure is caused by the force with which the ventricles contract.
What causes blood pressure?
