Blood Flashcards
1
Q
Blood categorization
A
–connective tissue, so it contains cells and a matrix
2
Q
plasma
A
- -contains the matrix of the blood
- -water, ions, urea, ammonia, proteins, and other organic and inorganic compounds
- -blood volume is regulated by controlling the amount of water in the plasma
3
Q
albumins
A
- -found in plasma
- -made in the liver
- -transport fatty acids and steroids
- -help regulate the osmotic pressure of blood by transferring substances across capillary walls
4
Q
immunoglobulins
A
–also known as antibodies
5
Q
serum
A
–plasma without the clotting protein fibrinogen
6
Q
plasma proteins
A
- -mostly made in the liver
- -act as a source of amino acids for tissue protein replacement
7
Q
gamma globulins
A
- -constitute antibodies
- -made in lymph tissue
8
Q
erythrocytes
A
- -bags of hemoglobin
- -no organelles
- -no nuclei
- -do not undergo mitosis
9
Q
hematocrit
A
–the red blood cell portion of the plasma only
10
Q
leukocytes
A
- -white blood cells
- -DO contain organelles
- -do not contain hemoglobin
- -neutrophils, lymphocytes, monocytes, eosinophils, basophils all fall in the category of leukocytes
11
Q
How are blood cells made?
A
–a stem cell residing in the bone marrow
12
Q
reticulocytes
A
- -erythrocyte that has just been released to the bloodstream
- -reticulocytes have no nucleus and lose their organelles within a few days of being released into the blood stream
13
Q
granular leukocytes
A
–nuetrophils, eosinophils, basophils
14
Q
granular leukocytes
A
- -monocytes
- -lymphocytes
- -megakaryocytes
15
Q
platelets
A
- -small portions of membrane-bound cytoplasm torn from megakaryocytes
- -do not contain a nucleus
- -do contain actin, myosin, mitochondria, residual pieces of Golgi and ER
- -capable of making prostaglandins and some important enzymes
- -important function in coagulation
