TEAS TEST
Which of the following structures changes the volume of the lungs?
a. alveoli
b. heart
c. trachea
d. diaphragm - ANSWER D. diaphragm
What is the respiratory systems main function - ANSWER transporting oxygen
from the atmosphere into the body's cells and moving carbon dioxide from the body's
cells
How many lobes does the right lung have? - ANSWER 3 (superior, middle, inferior)
How many lobes does the left lung have? Why? - ANSWER 2 because of the heart
How does gas exchange occur in the lungs? - ANSWER diffusion which is passive
transport mechanism
Where is the heart located - ANSWER mediastinum
Aveoli - ANSWER sacs of the lungs where oxygen and carbon dioxide are
exchanged by diffusion between the air and the blood
tidal volume - ANSWER the amount of air breathed in and out of the lungs during a
normal breath
Where is breathing controlled? - ANSWER medulla oblongata of the brain -
monitors carbon dioxide levels and blood ph.
cardiovascular system - ANSWER responsible for the movement of blood around
the body. This system allows for the nutrient distribution and waste removal.
What type of muscle is the heart? - ANSWER cardiac muscle - inbolunysty mudvlr
What are the upper chambers of the heart called? - ANSWER atria
What are the lower chambers of the heart called? - ANSWER ventricles
Arteries - ANSWER carry blood away from the heart
Veins - ANSWER Blood vessels that carry blood back to the heart
Capillaries - ANSWER single layer of endothelium that form a network that connect
arteries to veins in tissues
, Pulmonary loop - ANSWER carries deoxygenated blood from the right ventricle to
the lungs and returns oxygenated blood to the left atrium
Systemic loop - ANSWER carries oxygenated blood from the left ventricle to the
body, returning deoxygenated blood to the right atrium
Systole - ANSWER Contraction of the heart
Diastole - ANSWER Relaxation of the heart
What makes the "lub" sound? - ANSWER atrioventricular valves closing (mitral and
tricuspid valves)
What makes the dub sound? - ANSWER closing of semilunar valves
What controls heart contractions? - ANSWER Pacemaker - called the sinoatrial
node
Plasma - ANSWER clear pale yellow component of blood that carries red blood
cells, white blood cells and platelets throughout the body.
Hemoglobin - ANSWER The protein in red blood cells that carries oxygen from the
lungs to the rest of the body
Lymphocytes - ANSWER The two types of white blood cells that are part of the
body's immune system: B lymphocytes form in the bone marrow and release
antibodies that fight bacterial infections; T lymphocytes form in the thymus and other
lymphatic tissue and attack cancer cells, viruses, and foreign substances.
white blood cells - ANSWER granulocytes (basophils, eosinophils and neutrophils)
agranulocytes (monocytes and lymphocytes)
macrophage - ANSWER a large white blood cell that ingests foreign material
Leukocytes - ANSWER white blood cells, which protect the body again disease
Which heart chamber pumps blood toward the lungs - ANSWER right ventricle
Blood flow through the heart - ANSWER
What two chambers of the heart have thicker walls? Why? - ANSWER Ventricles
use a large amount of pressure to push blood to different parts of the body. This puts
quite a bit of force on these chambers, require them to be thicker.
Function of the digestive system - ANSWER break down food for absorption and
distribution of nutrients to the rest of the body
What controls the mechanical digestion and movement of food through the digestive
system - ANSWER the parasympathetic nervous system
