Chapter 14 Flashcards
Cardiovascular System
Red Blood Cells (erythrocytes)
move oxygen and other substances place to place
White Blood Cells (leukocytes)
main function is body defense
Platelets (thrombocytes)
first responders to a wall injury help plug leaks and start the blood clotting process. They are small pieces of cytoplasm that break off cells in bone marrow to enter the blood.
Arteries
carry blood away from the heart
Veins
carry blood toward the heart
Capillaries
form the transition between arteries and veins fine
What part of the heart delivers deoxygenated blood to the lungs
pulmonary artery
What part of the heart delivers richly oxygenated blood to the body?
Aorta
On the right side of the heart, blood flows from the right ventricle to the ?
pulmonatic valve to the pulmonary artery
how many chambers are in the heart?
4
What part of the heart delivers oxygenated blood to the heart?
pulmonary vein
The blood enters on the left side of the heart through the _____ and enters the left atrium. It then passes through the _____to enter the left ventricle
pulmonary vein & Bicuspid vein
What part of the heart delivers unoxygenated blood to the lungs?
pulmonary artery
pulmonary veins take unoxygenated blood away from the heart. True or False
false
the artiums are located below the ventricles. True or False
False
The bicuspid valve is located on the left side of the heart. True or False
True
___ Takes place when oxygen-rich blood travels to all body tissues except the lungs
systemic circulation
the particular blood vessel carries deoxygenated blood from the upper half of the body to the right atrium
super vena cava
___is a group of organs and tissues that act as transfer stations carrying needed materials and cells and removing their waste products.
circulatory system
__takes place when blood travels from the heart, through the lungs and back to the heart
pulmonary circulation
these are tiny blood vessels that carry blood to and from almost all body calls and connect arteries and veins
capillaries
which part of the heart is the largest and the strongest
the left ventricle
the pulmonary veins carry oxygenated blood back to the
left atrium
the particular blood vessel comes deoxygenated blood from the lower half of the body to the right atrium
inferior vena cava
the particular blood vessel carries oxygenated blood to the heart coming from the lungs
pulmonary vein
after blood leaves the left atrium it enters the __
left ventricle
this particular blood vessel carries deoxygnated blood away from the heart to the lungs
pulmonary artery
both the superior & inferior vena cava carry blood into the
right atrium
the heart pumps blood around the body through a network of blood vessels that is over ___ miles
80,000
after blood leaves the right atrium it enters the
right ventricle
after the blood leaves the left ventricle it enters the
aorta
The cardiovascular system is divided into what two parts?
pulmonary circulation & systemic circulation
Where is the heart located ?
The thoracic cavity. in the space between the two longs
the fibrous sac the heart is contained in
pericardium
The middle and thickest layer the muscular layer of the heart wall
myocardium
the outermost layer of the heart wall
epicardium
the membrane of the heart wall that lies on the internal surface of the myocaridum. composed of thin flat epithelium and forms the lining if the heart chambers
endocardium
the left and right atrium are separated by the
interatial septum
blind pouches that come off the main part of the atria and look like earflaps
auricles
these valves are located between the atria and the ventricles
atrioventricular valves or AV valves
what controls the blood flow out of the ventricles and into the arteries?
semilunar valves
responsible for bringing in nourishment and oxygen and taking away waste products
coronary arteries and veins
