TEAS TEST- THE 11 BODY SYSTEMS
QUESTIONS & ACCURATE
COMPLETE SOLUTIONS
The circulatory system (cardiovascular system) - CORRECT ANSWER -The
transportation highway for the entire body and consists of the heart, blood and blood
vessels.
The heart - CORRECT ANSWER -A muscular pump made out of cardiac muscle tissue
and pumps blood throughout the body.
-Rhythmic contractions of the heart enable blood to be transported throughout the body
-Consists of four chambers: the right and left atriums and the right and left ventricles
-It also has four valves that prevent the flow of blood back into the hearts chambers
after contraction.
-The four valves are the tricuspid and pulmonary on the right and the mitral and aortic
on the left.
Blood flow through the heart - CORRECT ANSWER 1. Deoxygenated blood enters into
the heart through the superior and inferior vena cabs
2.The blood travels into the right atrium and during contraction and during contraction of
the atrium, flows through the tricuspid valve into the right ventricle
3. The blood is pushed through the pulmonary valve into the pulmonary artery and lungs
when the right ventricle contracts.
4. At the lungs, it picks up
Oxygen. The oxygenated blood is then carried back to the heart (by the pulmonary
veins) into the left atrium, through the mitral valve and into the left ventricle
5. Contraction of the left ventricle forces blood through the aortic valve, though the aorta
and out to the entire body.
Blood - CORRECT ANSWER -Helps stabilize internal pH and hosts various kinds of
infection fighters
-An adult human has about five quarts of blood
-Blood is composed of red and white blood cells, platelets, and plasma
Plasma - CORRECT ANSWER -Constitutes over the of the blood volume and is mostly
water and serves as a solvent.
-Contains plasma proteins, ions, glucose, amino acids, hormones and dissolved
gasses.
Red blood cells - CORRECT ANSWER -Transport oxygen to cells and form red bone
marrow
, -Can live for a total of about two months
-Constantly being replaced by fresh ones
White blood cells - CORRECT ANSWER -Defend the body against infection and
removes various wastes.
-Include: lymphocytes, neutrophils, eosinophils and basophils.
Platelets - CORRECT ANSWER Are fragments of stem cells which serve an important
function in blood clotting
Arteries - CORRECT ANSWER Are blood vessels that transport blood away from the
heart to the capillaries.
-Branch into smaller arterioles which contract and expand based on signals from the
body
Arterioles - CORRECT ANSWER -Are the site where adjustments are made in blood
delivery to specific areas based on complex communication from body systems.
Veins - CORRECT ANSWER -Are blood vessels that transport blood from the
capillaries back to the heart.
-Have valves inside that help transport the blood back to the heart.
Capillaries - CORRECT ANSWER Are tiny blood vessels that transport blood from
arteries to veins within the body.
-Also serve as the location for the exchange of oxygen, carbon dioxide, fluid, and
nutrients within the body.
The respiratory system - CORRECT ANSWER -Provides air exchange and supplies
tissues with oxygenated blood.
The lungs - CORRECT ANSWER -The primary function of the lungs is breathing in
oxygen and exhaling carbon dioxide.
-This process begins as air is inhaled through the nose Into the trachea, passing into
the right and left bronchial tubes.
Cilia - CORRECT ANSWER -Within the bronchial tubes are tiny hairs called cilia, which
keep the airway clear by removing unwanted matter from the lungs.
Alveoli - CORRECT ANSWER -After leaving the bronchial tubes, air travels into the
Alveoli which are tiny air sacs that are surrounded by capillaries.
-The alveoli's permit the exchange of oxygen and carbon dioxide to occurs
-The oxygen is then transported by red blood cells into the blood stream.
Inspiration - CORRECT ANSWER -The diaphragm (an abdominal muscle that
contracts) pulls air into the lungs during inspiration which is the act of taking in
oxygenated air.
