The Heart Flashcards
General Function of Cardiovascular System
Transport blood throughout the body to allow exchange os substances between blood capilaries and bodys cells
Goal of the Cardiovascular System
Provide adequate perfusion of all the body tissues
define Perfusion
delivery of blood per unit time per gram of tissue (mL/min/g)
Veins blood flow move where
Arteries blood flow moves where
Veins are towards the heart
Arteries are away from the heart
How many chambers are in the heart?
what are they called?
where do they pump to?
Which one is the “recieving” chamber and which is the “pumping” chamber
4 chambers
Right Atrium, Left Atrium
Right Ventricle, Left Ventricle
Right side pumps deoxygenated blood to the lungs
Left Side pumps oxygenated blood to the body
Ventricles are the pumping chambers
Atrium are the recieving chambers
two of the hearts great vessels that transport blood from the ventricle away from the heart
pulmonary trunk= punps to the lungs
Aorts= pumps to the body
Large veins that delever blood to the heart into an atrium
Vena Cavae (Superios Vena Cava, Inferior Vena Cava Pulmonary Veins
2 sets of valves
Atrioventricular valves
semilunar valves
what is the atrioventricular Right side and Left side valve connect?
valves between the atrium and the ventricle
what does the semilunar valve connecT?
boundary between the ventricle and its associated atrieal trunk
Pulmonary semilunar valve
aortic semilunar valve
is there ever a back flow in the hear?
No it is always in one direction, does not have any back flow
Cardiovascular system is composed of two circulation routes
1
2
- Pulmonary Circulation
- Systemic circulation
Pulmonary circulation
includes movement od deoxygenated
