Which organ system in humans is most directly involved in the transport of oxygen?
digestive
nervous
excretory
circulatory
The flow of blood to and from the lungs is referred to as
pulmonary circulation
systemic circulation
autonomic circulation
somatic circulation
The concentration of oxygen is highest in the blood flowing through the
superior vena cava
inferior vena cava
pulmonary vein
pulmonary artery
A pulse can be detected most easily in
an artery
a vein
a capillary
a lacteal
The movement of blood from the legs toward the heart is hindered by gravity. The effect of gravity is counteracted by
smooth muscle in the capillaries
cilia lining the blood vessels
valves in the veins
lymph nodes near major vessels
Which statement best describes arteries?
They have thick walls and transport blood away from the heart.
They have thick walls and transport blood toward the heart.
They have thin walls and transport blood away from the heart.
They have thin walls and transport blood toward the heart.
Dissolved nutrients, wastes, and oxygen are exchanged between the blood and intercellular fluid through the walls of
arteries
veins
capillaries
ventricles
Which body structures have walls one cell thick?
veins and arteries
trachea and bronchi
capillaries and alveoli
lymph vessels and stomach
Which type of vessel normally contains valves that prevent the backward flow of materials?
artery
arteriole
capillary
vein
Bleeding from a small cut soon stops due to the release of enzymes from
platelets
activated antibodies
hemoglobin
white blood cells
An infection in the body might result in a sudden
decrese in the activity of antigens produced by the mitochondria
decrese in the amount of DNA present in the nuclei of cells
increase in the activity of white blood cells
increase in the number of red blood cells
Which heart structure is also known as "mitral"?
Bicuspid
Left atrium and right atrium
Left ventricle and right ventricle
Tricuspid
The liquid portion of blood that comprises 55% of the blood's volume is called:
erythrocyte
leukocyte
plasma
thrombocyte
When blood passes through the pulmonary valve, which vessel does it enter?
Aorta
Pulmonary artery
Pulmonary vein
Vena cava
What is the equation for cardiac output?
stroke volume (SV) x Pulse Rate in one minute (PR) = Cardiac Output (CO)
PR (pulse rate in 30 seconds) x PD (Pulse deficient) = CO (Cardiac Output)
stroke volume(SV) x PD (Pulse deficient) = CO (Cardiac Ouput)
force of beat x beats per minute = cardiac output
