Blood review

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
