Go with the flow
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
The name of the fluid that circulates through the lymphatic system
What is lymph
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 white blood cell is primarily responsible for immunity and can differentiate into B cells and T cells
What are lymphocytes
This is the largest chamber and is responsible for sending oxygenated blood into systemic circulation.
What is the L ventricle
This sensory receptor detects changes in blood pressure
What are baroreceptors
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 lymphatic collecting ducts services the entire body EXCEPT the R shoulder, arm, neck, and face
What is the thoracic duct
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
This lymphatic organ filters blood and is a site where damaged RBCs are phagocytized
What is the spleen
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
Blood pressure will be LOWEST in this type of vessel
What is vein
It is the conversion of fibrinogen into this that causes a blood clot to form
What is fibrin
This is an example of an ADAPTIVE, SPECIFIC defense mechanism
What is immunity
