BLOOD BASICS
This blood component carries oxygen.
erythrocytes (red blood cells)
These cell fragments are responsible for blood clotting
platelets
This blood type is known as the universal donor
O negative
This chamber receives deoxygenated blood from the body.
Right atrium
This circuit carries blood to the lungs.
The pulmonary circuit
This protein in red blood cells binds oxygen.
hemoglobin
This is the first step of hemostasis involving blood vessel constriction
vascular spasm
A person with Type B blood has these antibodies
Anti-A antibodies
This valve is located between the left atrium and left ventricle.
The mitral (bicuspid) valve
These vessels have valves to prevent backflow of blood
veins
This part of hemoglobin directly binds oxygen molecules
the heme group
This process allows white blood cells to leave capillaries
diapedesis
This factor determines whether blood is positive or negative
Rh factor
This chamber forms the apex of the heart
Left ventricle
This type of blood vessel is the smallest and most numerous in the body.
capillaries
This plasma protein helps maintain osmotic pressure and fluid balance
albumin
This final step of hemostasis forms a stable clot using fibrin
coagulation
This occurs when incompatible blood types are mixed
transfusion reaction
This phase of the cardiac cycle is when the heart contracts.
systole
This artery is unique because it carries deoxygenated blood.
The pulmonary artery
Blood pressure is measured in this unit.
mmHg
How could failure in the coagulation phase impact survival after injury?
Inability to form stable clots leading to excessive bleeding
Why can someone with AB+ blood receive blood from any donor type?
They have no antibodies against A, B, or Rh antigens
Why does the left ventricle have thicker walls than the right ventricle?
It pumps blood to the entire body at higher pressure
A patient has low RBC count, fatigue, and poor oxygen delivery. Diagnose the condition and explain the physiological cause.
Anemia; reduced RBCs → decreased oxygen transport to tissues
