What is the function of arterial blood?
Arterial blood carries oxygen from the lungs to other tissues.
What is the primary function of venous blood?
Venous blood carries CO2 and waste products from tissues to the lungs.
What percentage of the human body weight does blood account for?
7%
What is the normal blood volume in an average adult human?
Around 5 liters.
What is the normal blood pH range?
7.35-7.45.
What are the main components of human blood?
Plasma and formed elements (erythrocytes, leukocytes, thrombocytes).
What proportion of whole blood do erythrocytes (RBCs) constitute?
45%.
What is the life span of a mature red blood cell (RBC)?
120 days.
Which organ degrades old red blood cells after their life span?
Spleen and kupffer cells in the liver.
What do white blood cells (WBCs) do?
White blood cells are part of the immune system, destroying and removing old or aberrant cells and cellular debris, and attacking infectious and foreign agents.
What are platelets responsible for in the blood?
Platelets are responsible for blood clotting (coagulation).
What is the approximate volume of plasma in an average human?
2.7 - 3 liters.
What is the color of plasma?
Straw-colored.
What percentage of whole blood volume does plasma constitute?
55%.
What materials are transported by plasma to cells?
Plasma transports materials like ions, glucose, amino acids, and urea.
What percentage of plasma is composed of water?
92%.
What are the main components of plasma proteins?
Serum albumin and a great variety of serum globulins.
What are the functions of blood platelets?
Platelet factors initiate blood clotting and help minimize blood loss.
What is the normal range of leukocytes (white blood cells) in the blood?
4,000 – 11,000 per cubic millimeter.
What is the main function of leukocytes?
Leukocytes destroy invading microorganisms and cancer cells.
What is the function of antibodies and other proteins in blood?
Antibodies and other proteins destroy pathogenic substances.
What is the normal range of RBCs (red blood cells) in the blood for males?
5.2 million per cubic millimeter.
What is the normal pH range of blood?
7.35-7.45.
What materials are transported by blood between the lungs and the rest of the body?
Blood transports oxygen (O2) and carbon dioxide (CO2) between the lungs and the rest of the body.
What is the role of blood in regulating core body temperature?
Blood helps regulate core body temperature.
What are the main functions of blood platelets?
Platelet factors initiate blood clotting and help minimize blood loss.
What is the composition of serum, and how does it differ from plasma?
Serum is plasma without clotting factors and contains serum proteins, including serum albumin and a variety of serum globulins.
