Blood Basics
This component makes up about 90% of plasma.
What is water?
These cells transport oxygen through hemoglobin molecules.
What are erythrocytes (red blood cells)?
This blood type is considered the universal donor.
What is Type O?
These are the two upper chambers of the heart.
What are the atria?
These blood vessels carry blood away from the heart.
What are arteries?
These are the suspended cells found in blood.
What are formed elements?
This type of leukocyte engulfs and destroys bacteria.
What are neutrophils?
This process occurs when antibodies cause blood cells to clump together.
What is agglutination?
This structure separates the right and left sides of the heart.
What is the septum?
Gas exchange with body tissues occurs in these vessels.
What are capillaries?
This term describes the percentage of red blood cells in blood.
What is hematocrit?
These cell fragments are responsible for blood clotting
What are platelets (thrombocytes)?
This Rh blood type can develop antibodies after exposure to Rh-positive blood.
What is Rh-negative?
This valve is found between the left atrium and left ventricle.
What is the bicuspid (mitral) valve?
This structure acts as the natural pacemaker of the heart.
What is the SA node?
This process maintains the composition of plasma and internal balance in the body
What is homeostasis?
These leukocytes release histamines during allergic reactions and infections.
What are basophils?
This abnormal clot forms inside a blood vessel.
What is a thrombus?
This layer of the heart is responsible for contraction and is the thickest layer.
What is the myocardium?
Cardiac output is calculated using these two factors.
What are heart rate and stroke volume?
This blood protein helps regulate osmotic balance between blood and tissues.
What is albumin?
When monocytes leave the bloodstream and enter tissues, they become these cells.
What are macrophages?
This is the correct sequence after vessel injury during hemostasis.
What is vessel constriction → platelet plug formation → fibrin clot formation?
This is the correct pathway of blood leaving the right ventricle.
What is pulmonary arteries → lungs?
These structures help veins return blood to the heart despite low pressure.
What are valves, skeletal muscle pumping, and respiratory pumping?
