Anat. Blood and Heart
A person with antigen A on their red blood cells can give blood to someone with blood type(s)
A and AB
In figure 33-2 what is happening in diagram C
A blood clot has formed inside an artery
An artery has much thicker muscle layer than
All of the above
The human circulatory system
All of the above
Which of these is a function of the circulatory system
All of the above
T/F A stroke occurs when an area of the heart muscles dies
False
T/F The innermost layer of an artery is a layer of elastic, smooth muscle tissue
False
T/F The majority of carbon dioxide in the blood is attached to hemoglobin molecules inside red blood cells
False
T/F The systole pressure tell how much pressure is exerted when the heart relaxes
False
T/F When a platelet encounters a damage blood vessel, it releases fibrin, which causes a clot to form.
False
T/F Blood pressure is measured with a device called a sphygmomanometer
True
T/F Breathing is regulated mainly by response to the level of carbon dioxide detected in the blood
True
T/F Contraction of the heart is initiated by a cluster of cardiac muscle cells called the sinoatrial node
True
T/F New red blood cells are produced by stem cells in the bone marrow
True
T/F The lymphatic system returns fluids from around cells back to the blood vessels
True
T/F The smallest bronchioles end in clusters of air sacs called alveoli, where gases are exchanged in the lungs
True
T/F Type O blood contains neither A nor B antigens
True
A condition known as atherosclerosis results in
a narrowing of the inner walls of blood vessels
The sudden death of brain cells when their blood supply is interrupted is called
a stroke
Vessels that carry blood away from the heart are called
arteries
Through which path does blood typically flow through the circulatory system?
arteries, capillaries, veins
An abnormality involving the platelets would probably affect the process of
blood clotting
Which are the components of the circulatory system
blood, blood vessels, heart
The smallest and most numerous blood vessels in the body are the
capillaries
The pressure exerted on the inner walls of the arteries when the heart relaxes between beats is the {blank} pressure
diastolic
Vitamins, salts, and proteins : plasma solutes ::
erythrocytes and leukocytes : blood cells
When the diaphragm and rib cage muscle relax,
exhalation occurs
Blood pressure : sphygmomanometer ::
heart electrical impulse : electrocardiogram
The iron-containing molecule in red blood cells is called
hemoglobin
The pacemaker responsible for starting a heartbeat
is a small bundle of cells at the entrance to the right atrium
Blood entering the right atrium
is deoxygenated
Refer to the illustration above. In the diagram, blood in chamber A
is full of oxygen
Pulmonary circulation flows to and from the
lungs
A heart attack can result from the blockage of a blood vessel because of
plaque build-up
In figure 33-2, what is happening in diagram A
plaque has built up in the wall of a blood vessel
Infections generally result in an increase in the number of
platelets
Which blood cells are most numerous in the body?
red
The heart chamber that receives blood from the venae cavae is the
right atrium
Which of these organs removes old or damaged blood cells from the blood that flows through it
spleen
The ventricles are
the chambers of the heart that pump blood to the lungs and the rest of the body
Refer to the illustration above. The vessels indicated by C in the diagram carry deoxygenated blood. The vessels are
the pulmonary arteries
If a blood vessel has valves, it probably is a(n)
vein
When an infection occurs, the number of
white blood cells increases
