Unit 3: Blood Part A and B

Question 1

Blood

Answer 1

connective tissue that is specialized for transport and exchange of solutes and fluids

Question 2

What are the components of blood?

Answer 2

a. Plasma – suspension of water and solutes
b. Formed elements – cells

Question 3

What is the volume of blood in men and women?

Answer 3

Volume is ~5 to 5.5 liters in men, and ~4
liters in women (dependent on body size)

Question 4

Describe the composition of plasma

Answer 4

Composed of:
- water; 90%

• dissolved solutes:
  
  • proteins
• electrolytes (e.g. Na+, Cl -, H+, K +, Ca2+, HCO 3-)
  Functions: membrane excitability; buffers (HCO3-)
• nutrients (e.g. glucose, amino acids, lipids, vitamins)
• gases (e.g. O 2, CO 2, N2)
• metabolic waste (e.g. urea, creatinine)

Question 5

Proteins

Answer 5

determines plasma colloid osmotic pressure (π C) and can act as a buffer to help maintain blood pH

Question 6

List the major types of plasma proteins

Answer 6

• albumins
• globulins
• fibrinogen
• transferrin
• peptide/ protein hormone

Question 7

Albumins

Answer 7

60% of all proteins; primarily responsible for π C

Question 8

Globulins

Answer 8

α, β globulins transport lipids, some metal ions and hormones;

γ (gamma) globulins (immunoglobulins/antibodies); SYNTHESIZED AND SECRETED BY SPECIALIZED BLOOD CELLS

Question 9

Fibrinogen

Answer 9

clotting protein

Question 10

Transferrin

Answer 10

transports iron that is not part of hemoglobin

Question 11

What makes most plasma proteins & secretes them into the blood?

Answer 11

liver

Question 12

Plasma

Answer 12

fluid portion of the blood
identical in composition to the interstitial fluid except it had plasma proteins
