In the liver

Question 14

three different types of plasma proteins

Answer 14

albumin, globulin, fibrinogen

Question 15

albumin

Answer 15

most abundant, used to transport proteins, lipids, steroids, increases blood viscosity

globulin

Answer 16

role in immune response, used to transport ions, lipids, and hormones

Answer 19

blood stem cell

Question 20

characteristics of erythrocytes

Answer 20

most abundant blood cell (25 trillion in body)
no nuclei, no mitochondria (it’ll steal oxygen), no ribosomes
stays within vessel walls
hemocrit = %RBC
biconcave structure
cell filled with hemoglobin
iron is recycled back to liver

Question 21

What is the fate of a red blood cell?

Answer 21

Lives about 3-4 months
Aged and damaged cells are eaten by macrophages in liver, spleen, and bone marrow
Cells in kidneys detect low O2

Question 22

characteristics of leukocytes

Answer 22

defense against infection and disease
only live a few days
most use phagocytosis to destroy foreign bodies
most found outside vessel walls but within connective tissue
store and release WBC during infection

Answer 26

most abundant
found in tissue
multi-lobed nucleus
fights bacterial infection

Question 27

eosinophils

Answer 27

found in walls of GL tract, releases chem to reduce inflammation, fights parasitic infection

Question 28

eosinophils

Answer 28

found in walls of GL tract, releases chem to reduce inflammation, fights parasitic infection

Question 29

basophils

Answer 29

no phagocytosis, releases chem to promote inflammation, allergic response

Question 30

monocytes

Answer 30

Largest WBC, kidney-bean shaped nucleus, becomes a type of macrophage

Question 31

lymphocytes

Answer 31

immune cell, most in lymph tissue, fights viral infection

Question 32

thrombocytes characteristics

Answer 32

membrane-bound fragment of larger cells, no nucleus but some organelles, initiates blood clotting in blood vessels
