Chapter 9 PAGE 175 Flashcards
BLOOD circulates in what system
CARDIOVASCULAR SYSTEM
the HEART is located between the
LUNGS
the thin MEMBRANE that lines the CHAMBERS and VALVES
ENDOCARDIUM
the thick MUSCLE layer that makes MOST of the HEART
MYOCARDIUM
the thin MEMBRANE that covers the HEART
EPICARDIUM
EPI: ON
fibrous SAC that CONTAINS the HEART and ANCHORS its surrounding STRUCTURES
PERICARDIUM
the hearts UPPER RECEIVING chambers
ATRIUM
the hearts LOWER PUMPING chambers
VENTRICLE
SEPARATES the two VENTRICLES
INTER VENT RICULAR SEPTUM
the HEART pumps blood through how many CIRCUITS
TWO
the RIGHT side of the HEART FUNCTIONS are
to OXYGENATE through the PULMONARY CIRCUIT
the LEFT side of the HEART FUNCTIONS are
to pump blood to the REMAINDER of the body through the SYSTEMIC CIRCUIT
the RIGHT ATRIUM receives
blood in low OXYGEN from all BODY tissues
the RIGHT ATRIUM receives blood for all BODY TISSUES through the
SUPERIOR VENA CAVA and the INFERIOR VENA CAVA
the blood ENTERS the RIGHT VENTRICLE and is pumped TO the lungs
PULMONARY ARTERY
the blood returns from the LUNGS HIGH in OXYGEN and enters the LEFT ATRIUM through the
PULMONARY VEINS
another NAME for the right AV VALVE is
TRICUSPID VALVE
because of it has three cusps (flaps)
another NAME for the left AV VALVE is
BICUSPID VALVE
valves leading into the PULMONARY ARTERY and the AORTA is called
SEMILUNAR VALVES
shaped like a HALF MOON
CARRIES blood TO and FROM the LUNGS
PULMONARY CIRUIT
CARRIES blood TO and FROM other PARTS of the BODY
SYSTEMIC CIRCUIT
