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
