  • What is the typical pH range of human blood, and why is it important?
    The typical pH range of human blood is 7.35 to 7.45, which is slightly alkaline and essential for the proper function of blood components.
  • What is the hematocrit, and what does it indicate?
    The hematocrit is the percentage of blood volume made up of red blood cells (erythrocytes), indicating the proportion of RBCs in the blood.
  • What is the buffy coat, and what does it contain?
    The buffy coat is a thin layer in blood that contains white blood cells (leukocytes) for immunity and platelets (thrombocytes) for blood clotting.
  • How does blood help regulate body temperature?
    Blood helps regulate body temperature by distributing heat throughout the body and adjusting blood flow to the skin to either retain or release heat.
  • What is the approximate percentage of blood volume made up by plasma?
    Plasma makes up about 55% of the total blood volume.
  • What is the normal range for hematocrit values, and how do they differ between males and females?
    The normal hematocrit range is 36% to 50%, with males generally having higher values than females.
  • What are the formed elements of blood?
    The formed elements of blood are erythrocytes (red blood cells), leukocytes (white blood cells), and platelets (thrombocytes).
  • What is the significance of the viscosity of blood compared to water?
    Blood is more viscous and denser than water, which helps it transport substances efficiently and maintain proper circulation.
  • What is the role of albumin in blood plasma?
    Albumin is a plasma protein that helps maintain fluid balance and osmotic pressure in the blood.
  • What is the typical pH range of human blood, and why is it important?
    The typical pH range of human blood is 7.35 to 7.45, which is slightly alkaline and essential for the proper function of blood components.
  • How many quarts of blood are typically found in the human body?
    The average adult has about 4 to 6 liters of blood, which is approximately 4.2 to 6.3 quarts.
  • How many gallons of blood are typically found in the human body?
    The average adult has about 1 to 1.5 gallons of blood.
  • What are the two major components of blood?
    The two major components of blood are plasma and formed elements (erythrocytes, leukocytes, and platelets).
  • What is the liquid portion of the blood called?
    The liquid portion of the blood is called plasma.
  • What is the blood volume of an average-sized adult?
    An average-sized adult has about 4 to 6 liters of blood.
  • What is blood plasma minus fibrinogen and other clotting factors called?
    Blood plasma minus fibrinogen and other clotting factors is called serum.
  • What is one unhealthy effect of blood doping?
    Blood doping can increase blood viscosity, which may lead to dangerous blood clots.
  • What is the liquid medium of blood?
    The liquid medium of blood is plasma.
  • What is the liquid portion of blood called?
    The liquid portion of blood is called plasma.
  • What are the two major components of blood?
    The two major components of blood are plasma and formed elements.
  • Which component makes up the majority of blood?
    Plasma makes up the majority of blood, about 55% of total blood volume.
  • Which blood component primarily contributes to plasma osmotic pressure?
    Albumin is the blood component that primarily contributes to plasma osmotic pressure.
  • What is the process by which blood cells are formed called?
    Blood cells are formed by the process of hematopoiesis.
  • What is the fluid portion of the blood called?
    The fluid portion of the blood is called plasma.
  • What are the most prevalent proteins in blood plasma?
    The most prevalent proteins in blood plasma are albumin, globulins, and fibrinogen.
  • What is the fluid part of the blood called?
    The fluid part of the blood is called plasma.
  • How would you best describe the two components of blood?
    Blood consists of plasma (the liquid extracellular matrix) and formed elements (cells and cell fragments).
  • Serum is blood plasma minus its what?
    Serum is blood plasma minus its clotting factors, such as fibrinogen.
  • What is the buffy coat found in centrifuged whole blood?
    The buffy coat is a thin layer containing white blood cells (leukocytes) and platelets (thrombocytes), making up less than 1% of blood volume.
  • What are the most abundant proteins in blood plasma?
    Albumin is the most abundant protein in blood plasma.
  • What are the two main components of blood?
    The two main components of blood are plasma and formed elements.
  • What percentage of blood plasma is water?
    Blood plasma is about 90% water.
  • Formed elements make up about what percentage of blood?
    Formed elements make up about 45% of blood volume.
  • What is the liquid part of the blood called?
    The liquid part of the blood is called plasma.
  • What is blood plasma without clotting factors called?
    Blood plasma without clotting factors is called serum.
  • What is the liquid portion of blood called?
    The liquid portion of blood is called plasma.
  • What is the liquid portion of blood called?
    The liquid portion of blood is called plasma.
  • What is the fluid part of the blood called?
    The fluid part of the blood is called plasma.
  • What are the two major components of blood?
    The two major components of blood are plasma and formed elements.
  • What is the liquid part of blood called?
    The liquid part of blood is called plasma.
