CIRCULATORY SYSTEM Flashcards
Cardiodhaegeaqwi
Also called the cardiovascular system or the vascular system, is an organ system that permits blood to circulate and transport nutrients
CIRCULATORY SYSTEM
Hollow, muscular organ about the size of a fist. It is responsible for pumping blood through the blood vessels by repeated, rhythmic contractions.
HEART
is the portion of the circulatory system which carries deoxygenated blood away from the right ventricle, to the lungs, and returns oxygenated blood to the left atrium and ventricle of the heart.
PULMONARY CIRCULATION
provides the functional blood supply to all body tissue. It carries oxygen and nutrients to the cells and picks up carbon dioxide and waste products. ________________________ carries oxygenated blood from the left ventricle, through the arteries, to the capillaries in the tissues of the body.
SYSTEMIC CIRCULATION
is a dense connective tissue that surrounds the heart and maintain its position acts as protection for the heart and big vessels, and a lubrication to reduce friction between the heart and the surrounding structures.
PERICARDIUM
the outer layer
EPICARDIUM
the middle, muscular layer
MYOCARDIUM
the inner layer
ENDOCARDIUM
The ______________ receives oxygen-poor blood from the body and pumps it to the right ventricle.
RA (RIGHT ATRIUM)
The ______________ oxygen-rich blood from the lungs and pumps it to the left ventricle.
LA (LEFT ATRIUM)
The ________________ pumps the oxygen-poor blood to the lungs.
RV (RIGHT VENTRICLE)
The ____________ pumps the oxygen-rich blood to the body.
LV (LEFT VENTRICLE)
Separates the top right chamber (right atrium) from the bottom right chamber (right ventricle).
Opens to allow blood to flow from the right atrium to the right ventricle.
Prevents the back flow of blood from the right ventricle to the right atrium.
TRICUSPID VALVE
Separates the right ventricle from the pulmonary artery.
Opens to allow blood to be pumped from the right ventricle to the lungs (through the pulmonary artery) where it will receive oxygen.
Prevents the back flow of blood from the pulmonary artery to the right ventricle.
PULMONARY VAVLVE
Separates the top left chamber (left atrium) from the bottom left chamber (left ventricle).
Opens to allow blood to be pumped from the lungs to the left atrium.
Prevents the back flow of blood from the left ventricle to the left atrium.
MITRAL (BIOSCUPID) VALVE
Separates the left ventricle from the aorta.
Opens to allow blood to leave the heart from the left ventricle through the aorta and the body.
Prevents the backflow of blood from the aorta to the left ventricle.
AORTIC VALVE
The _________________ the great venous trunks that return deoxygenated blood from the systemic circulation to the right atrium of the heart.
SUPERIOR VENA CAVA (SVC)
The _____________ is a large blood vessel responsible for transporting deoxygenated blood from the lower extremities and abdomen back to the right atrium of the heart.
INFERIOR VENA CAVA (IVC)
The _________ are the veins that transfer oxygenated blood from the lungs to the heart.
PULMONARY VEINS
The ___________________ are blood vessels that carry blood from the right side of the heart through to the capillaries of the lungs. The blood that is carried is, unlike other arteries, without oxygen (“deoxygenated”).
PULMONARY ARTERIES
The ______________ is the large artery that carries oxygen-rich blood from the left ventricle of the heart to other parts of the body.
AORTA
are the channels or conduits through which blood is distributed to body tissues.
BLOOD VESSELS
transports blood from the right ventricle to the lungs and back to the left atrium.
PULMONARY VESSELS
carries blood from the left ventricle to the tissues in all parts of the body and then returns the blood to the right atrium.
