What is blood made up of?
Has living blood cells called formed elements, suspending in a nonliving fluid matrix called plasma. The fibers of blood only become visible during blood clotting.
what is its category as a tissue?
connective tissue
If a blood sample is centrifuged, the heavier blood cells become packed at the bottom of the tube. Most of this compacted cell mass is composed of:
erythrocytes
and the volume of blood accounted for by these cells is referred to as the:
Hematocrit
The less dense.....rises to the top and constitutes about 45% of the blood volume
plasma
The so called buffy coat composed of...and.... is found at the junction between the other two blood elements
Leukocytes, platelets
the buffy coat accounts for less than....% of blood volume
1
blood is scarlet red when it is loaded with:
Oxygen
salts and Globulin
important in osmotic balance and pH balance/buffering
water
Major blood solvent for transporting other substances
albumin
protein responsible for lipid transport and immunity
Fibrinogen
protein responsible for blood clotting
erythrocytes
formed element that transports oxygen
leukocytes
defense and immunity against bacteria and viruses
platelets
formed element responsible for blood clotting
what four types of substances are transported by blood?
Nutrients, waste products, respiratory gases, hormones
erythrocytes
anucleate
Few organelles, no mitochondria
Hemoglobin present
Aplastic anemia
the bone marrow is destroyed or inhibited
hemolytic anemia
RBCs are destroyed as a result of bacterial infection
hemorrhagic anemia
A consequence of acute blood loss (hemorrhage)
iron deficiency anemia
result of inadequate intake of iron- rich foods or chronic bleeding
pernicious anemia
common problem for people who have had a portion of their stomach removed to manage bleeding ulcers and can no longer absorb vitamin B12
sickle cell anemia
genetic disorder in which abnlrmal hemoglobin is prkduced and become spiky under hypoxic conditions
Leukocytes in order from most abundant to least
Neutrophils
Lymphocytes
Monocytes
Eosinophils
Basophils
Eosinophil
increases in number during allergy attack. Destroys parasitic worms
Basophil
releases histamine during inflammatory reactions
Neutrophil
granulocyte with the smallest granules
Lymphocyte
phagocytic leukocyte that avidly engulfs bacteria and fungi
Found in lymphatic tissue, can be B cells or T cells
Different groups either produce antibodies or attack tumors and viruses
monocytes
Increases in number during chronic infections, the largest WBC
platelets
necessary for blood clotting
Red blood cell
Also called an erythrocytes
megakaryocytes
Multinucleate cells that fragment apart into platelets
