Mitral valve (bicuspid valve)
haem/a/o
Blood
erythr/o
Red OR Red blood cells
leuc/o
White OR White blood cells
reticul/o
Reticulocyte
A reticulocyte is an immature red blood cell (RBC) that is produced in the bone marrow. Reticulocytes are released into the bloodstream, where they mature into RBCs within one to two days.
myel/o
Marrow

Lack of OR Deficiency
Find the most common name and Describe the Thrombocytes
Thrombocytes also known as Platelets job is to protect the body against bleeding through clotting
-aemia
Condition of blood
-poiesis

Artery
ather/o
Atheroma OR A fatty plaque lining a blood vessel
aneurysm/o
Aneurysm OR Dilatation
What are Capillaries job in the body?
Capillaries are tiny blood vessels that are responsible for the exchange of oxygen and carbon dioxide into and out of the tissues layers.
What is Vasoconstriction?
During vasoconstriction, the muscle layer (Tunica Media) narrows, and reducing the space inside the artery or vein (Tunica Intima)
What is Vasodilation?
During vasodilation, the muscle layer (Tunica Media) of the blood vessel retracts, widening the space inside the artery or vein (Tunica Intima)
Name blood’s 3 major functions
Transportation, Regulation, Protection
Explain why venous blood is much darker than arterial blood
The Venous Blood is darker because it is deoxygenated, and the Arterial Blood is brighter/lighter because it is oxygenated
Find the most common name and Describe the Erythrocyte

What is the difference of Heart Attack vs. Cardiac Arrest?
A Heart Attack primarily occurs when there is a blockage of the Coronary Arteries, whereas Cardiac Arrest is when the Cardiac Conduction System is failing.
Define blood pressure
The pressure the blood puts against the blood vessels walls
What is the primary function of the Coronary Arteries?
To provide oxygenated blood to the heart muscle
Define Systolic blood pressure
The pressure blood put against blood vessel walls during a contraction of the heart
What is a Heart Attack?
A Heart Attack is when blood supply to the heart muscles gets blocked therefore the cells cannot make ATP leading to the muscle cells death and losing function in the heart.
Define Diastolic blood pressure
The pressure blood puts against blood vessels when the heart relaxes
