Blood Basics
Blood is considered what type of tissue because it consists of cells suspended in a matrix?
Connective Tissue
Erythrocytes
These blood cells are responisble for immune defense
leukocytes
Platelets are also known as
thrombocytes
The first step to hemostasis is
vascular spasm
This liquid portion of blood makes up about 55% of total blood volume
The iron-containing molecule responsible for binding oxygen in red blood cells.
What is hemoglobin
Which white blood cell is the most abundant in circulation
neutrophils
After a cloto forms, this process gradually breaks it down to restore normal blood flow
Fibrinolysis
A patients lab results show:
low Hemoglovin
Low Hematocrit
Low RBC count
The patient reports fatigue and shortness of breath during mild activitywhich condition is mos likely present
Anemia
Approximately what percentage of plasma is water?
90%
The hormone that stimulates red blood cell production
These white blood cells produce antibodies
B lymphocytes
The protein threads that stabilize a blood clot
Fibrin
A patient with severe dehydration has a hematocrit of 55%
Why is the hematocrit present?
decreased plasma volume
hematocrit
Where does erythropoiesis primarily occur in adults?
Red bone marrow
This type of white blood cells increase during parasitic infection and allergic reactions
Eosinophils
This viamin is essential for normal blood clotting factor synthesis
Vitamin K
A patient receiving chemotherapy develops frequent infections. Why?
Leukocyte count is lowered
The yellow color of plasma is primarily due to the presence of this protein
Albumin
The average lifespan ofo a red blood cell is approximately
120 days
These white blood cells release histamine and participate in inflamatory responses
Basophils
During platelet plug formation, platelets attach to exposed collagen through this adhesive protein
A patient with cyrrhosis bruises easily and experiences prolonged bleeding.
This occurs because the liver normally produces:
clotting factors
