Heart
This is one of the primary roles of the cardiovascular system.
What is supplying tissues with oxygen and nutrients?
This can be felt when the arteries expand in rhythm with the contraction of the heart.
What is the pulse?
In the ABO system this determines the blood type.
What are antigens?
Endocardium, myocardium, epicardium
What are the three layers of cardiac tissue?
The veins that deoxygenated blood travels to enter the heart.
What are the superior and inferior vena cava?
This is also known as the packed cell volume and determines the percentage of the blood that is made up of red blood cells.
What is hematocrit?
This is the normal resting heart rate for adults
What is 60-100 beats per minute?
Plasma, Red Blood Cells, white blood cells and platelets
What are the components of blood?
The outermost layer of the heart wall is called the epicardium, which also forms the inner layer of this
What is the pericardium?
This is the valve that separates the right atrium from the right ventricle.
What is the tricuspid valve?
These types of white blood cells include Neutrophils, Eosinophils and Basophils.
What are granulocytes?
This is the normal healthy adult blood pressure.
What is 120/80?
This is the approximate amount of blood a healthy adult contains.
What is 5 liters?
This is the innermost layer of smooth muscle that lines the chambers of the heart and allows blood to flow smoothly
What is the Endocardium?
Deoxygenated blood leaves the right ventricle passing through the pulmonary semilunar valve to the pulmonary arteries to this organ.
What are the Lungs?
This is the procedure performed to determine the number of red and white blood cells in an individual.
What is a CBC or complete blood count?
This is the top number and the pressure on the arteries when the heart contracts.
What is systolic pressure?
The blood vessels travel in one direction leaving the heart through arteries and then branch into these smaller blood vessels.
What are arterioles?
This is the thick layer of muscle tissue that allows the heart to contract and relax, propelling blood throughout the body
What is the Myocardium?
These veins are how the oxygenated blood return to the heart from the lungs.
What are the pulmonary veins?
Hematopoiesis is the formation of RBC's and it occurs in this portion of the bone.
What is the bone marrow?
This is the bottom number and the pressure on the arteries when the heart is relaxed.
What is diastolic pressure?
These are the most abundant blood vessels in the body and are so small that red blood cells must travel single file. Because they are so thin oxygen, carbon dioxide, nutrients and waste easily diffuse through them
What are capillaries?
The protective sac that loosely surrounds the heart
Pericardium
This is the result of the left ventricle generating pressure to pumping blood throughout the body.
What is thicker myocardium (heart muscle)?
