What part of the body makes blood?
The kidneys
The pancreas
The liver

rib cage
This body part makes sure food goes to the stomach and air to the lungs
windpipe
epiglottis
trachea
bronchi
The pipes that bring air to the lungs are called
tailpipe
plumbing
epiglottis
bronchi
Where in the lungs does the blood exchange oxygen and carbon dioxide
windpipe
epiglottis
trachea
alveoli
Why is the nose considered part of the respiratory system
because it is connected to the sinuses
because it filters dust from the air
because smell is important
because without it we could not breathe
The smallest blood vessels are the
arteries
arterioles
capillaries
veins
Blood flows fastest in the
Arteries
Capillaries
Veins
Venules
The right atrium
delivers deoxygenated blood to the lungs
delivers oxygenated blood to the body
receives deoxygenated blood from the body
receives oxygenated blood from the lungs
Blood from the LEFT ventricle goes to the
aorta
left atrium
right atrium
left ventricle
The valves in the veins are to
control blood flow
divert blood to different areas
prevent backflow
regulate blood pressure
What does an antigen do?
fights disease
makes leucocytes
stimulates an immune response
all three
Thrombocytes
clot blood with the help of Vitamin K
destroy blood clots
lead to aneurisms
mend bones
The atria (two atriums) in the heart have what function?
collect in-coming blood
restrict blood flow
send blood out of the heart
none of these
De-oxygenated blood is first received in the
left atrium
left ventricle
right atrium
right ventricle
High Blood pressure is known as
hypersomnia
hyperventilation
hypertension
hypoxia
Which structures filter and moisten air as it passes through the human respiratory system?
cilia and mucous membranes
alveoli and cartilage rings
diaphragm and bronchioles
epiglottis and bronchi
Which respiratory structure is supported by rings of cartilage?
trachea
alveolus
bronchiole
pharynx
Which sequence correctly indicates the branching pattern of the human respiratory system?
trachea -> bronchi -> bronchioles -> alveoli
trachea -> bronchioles -> bronchi -> alveoli
alveoli -> trachea -> bronchioles -> bronchi
alveoli -> bronchioles -> trachea -> bronchi
Which structure in humans is lined with ciliated mucous membrane, is supported by cartilaginous rings, and functions as a passageway for air?
esophagus
alveolus
pharynx
trachea
In humans, which structure prevents food from entering the trachea?
epiglottis
alveolus
mucous membrane
cartilage ring
The cellular process which uses oxygen and sugar to produce energy is called
photosynthesis
cell division
cellular respiration
DNA replication
What is the main function of gas exchange
To remove carbon dioxide and supply oxygen to the body
To remove oxygen from the body
To supply carbon dioxide and remove oxygen from the body
To supply water to the body cells
Which structure shown in the diagram below contracts, causing a pressure change in the chest cavity during breathing?
A
B
C
D
Which part of the human respiratory system is a thin, moist membranous structure where gas exchange occurs?
trachea
bronchus
epiglottis
alveolus
Which part of the human respiratory system is correctly paired with a description of its structure?
alveolus – microscopic sac containing rings of cartilage and ciliated membranes
pharynx – cavity lined with flagellated mucous membranes
bronchiole – small branching tubule lacking cartilaginous rings
trachea – thin, moist membrane surrounded by capillaries
In the human respiratory system, bronchioles directly connect the
trachea and pharynx
bronchi and alveoli
nasal cavity and trachea
epiglottis and larynx
In humans, the thin, moist membranes of the alveoli are surrounded by
bronchi
the epiglottis
capillaries
lymph vessels
In humans, what happens when the breathing rate increases?
Additional oxygen will diffuse into the blood as carbon dioxide diffuses out of the blood in the lungs.
Additional carbon dioxide will diffuse into the blood as oxygen diffuses out of the blood in the lungs.
Oxygen from body cells will diffuse more rapidly into red blood cells.
Increased oxygen dissolved in the blood will stimulate the cerebrum to slow the breathing rate.
An allergic reaction characterized by the constriction of the bronchial tubes is known as
coronary thrombosis
arthritis
asthma
emphysema

thymosin
antidiuretic hormone
Which of the following is NOT one of the major processes controlled by hormones?
digestion
reproduction
growth & development
regulating metabolism
Negative feedback means that an increase in a substance will trigger
decreased production of that substance
increased production of that substance
increased production of other substances
stopping the production of another substance
Which hormone promotes growth in long bones and skeletal muscles?
