Normal blood flow starts with deoxygenated blood returning to the heart through this vessel
This body system is a closed circuit and includes the heart & blood vessels
What is the cardiovascular system
These vessels typically carry deoxygenated blood
What are veins
This type of blood cell is responsible for carrying oxygen and has a biconcave shape
What is a red blood cell
True or false: Blood pressure refers to systemic arterial pressure.
True
This is the heart chamber the vena cava empties into
What is the R atrium
This is the outermost layer of the heart
What is the epicardium
Nutrient and gas exchange occurs in these vessels
What are capillaries
This type of blood cell is responsible for preventing infection and has 5 types
What is a white blood cell
This type of sensory receptor detects changes in blood pressure and can be found in the carotid sinus.
What are baroreceptors
This is the largest chamber and is responsible for sending oxygenated blood into systemic circulation.
What is the L ventricle
This structure DIVIDES the 2 ventricles
What is the interventricular septum
These are the only veins that carry oxygenated blood
What are the pulmonary veins
These 2 types of white blood cells are the most phagocytic
What are neutrophils and monocytes
This is the equation for BP.
What is BP= CO X PR
This is the first of the AV valves and lies between the R atrium and R ventricle
This part of the cardiac conduction system is know as the pacemaker of the heart
What is the SA node
This is the largest diameter vessel that carries oxygenated blood
What is the aorta
The type of blood is known as the universal donor because it contains no antigens and both antibodies
What is O blood
These 5 factors influence blood pressure
What is blood volume, HR, SV, blood viscosity, and peripheral resistance
This is the 2nd semilunar valve and lies between the L ventricle and the aorta
What is the aortic valve
This part of a vein prevents the blood from going backwards (only veins have these structures)
What are valves
These 3 processes assist the veins in getting deoxygenated blood back to the heart
What is skeletal muscle contraction, respiratory movements, and venoconstriction
It is the conversion of fibrinogen into this that causes a blood clot to form
What is fibrin
Blood pressure will be the LOWEST in this type of vessel.
