What is the difference between blood and plasma?
|
Blood = Cells + plasma
Plasma = Water, protein, and solutes. |
|
What is a reticulocyte?
|
new RBC’s from bone marrow – complete hemogobin synthesis & mature 1-2 days after entering circulation
|
|
RBC proliferation is up-regulated by kidney hormone...?
|
erythropoietin
|
|
this WBC has 3 lobes and is the first phagocytic cell to appear during bacterial inflammation
|
Neutrophil
note: They roll across the endothelium until they leave the blood and become actively phagocytic. |
|
this WBC has a lobulated nucleus and has granules with hydrolytic enzymes, histamine, heparan sulfate proteoglycan, & slow reacting substance.
|
Basophil
|
|
This WBC is used to fight parasitic infections and contains granuales with lysosomal enzymes and major basic protein, MBP
|
Eosinophils
note: MBP is an anti-parasitic agent |
|
Phagocytic leukocyte with a oval or kidney bean-shaped nucleus
important in regulation of immune response and inflammation what WBC? |
Monocyte
|
|
Nucleus is round/oval in small/medium lymphocytes & may be more reniform in large lymphocytes. Very little cytoplasm evident. They ARE NOT phagocytic
|
Lymphocytes
|
|
Memory cells and plasma cells are what type of lymphocytes
|
B-lymphocytes
note: T-lymphocytes: mature in thymus. Killer T cells: involved in graft and transplant rejection. Their normal role is to lyse virus-infected cells displaying viral antigens. Helper T cells: enhance B and T lymphocyte activity Suppressor T cells: suppress B and T lymphocyte activity |
|
Why is adult bone marrow less hematopoietic than in fetal development?
|
because it regresses from hematopoietic red marrow to fat-storing yellow marrow
note: Adult red marrow is found in vertebral bodies, ribs, sternum, iliac bones, proximal humerus and proximal tibia. |
|
what type of arteries are found in the Aorta, pulmonary, common carotids, subclavians, & common iliac arteries?
|
Elastic
|
|
these blood vessels have a single endothelial layer surrounded by thin sheath of reticular & collagenous fibers & some pericytes.
|
Capillary
|
|
These blood vessels have several smooth muscle layers between the endothelial lining of the lumen and the adventitia
|
Arterioles
|
|
what type of capillaries are found in the GI tract, endocrine glands, renal glomerular tubules (no basal lamina), choroid plexus, & ciliary body
|
Fenestrated
|
|
what type of capillares are found in the liver and hemopoietic organs (spleen, bone marrow)?
|
Sinusoidal
|
|
What are the 2 "pulps" in the spleen and their basic functions?
|
White:
--made of B&T lymphocyte cell islands; surrounds and follows arteries Red: --Removal of old and damaged RBCs --iron is released and transported to the marrow for new RBCs |
|
What do direct and indirect blood levels of bilirubin tell you? what if they are elevated (what type of things could be going on)?
** |
Direct = conjugated bilirubin (↑ in bile duct blockage, cirrhosis, hepatitis since conjugated bilirubin cannot exit the liver in the normal manner through the duodenum.)
Indirect = unconjugated bilirubin (↑ in anemias, other blood disorders. The liver is operating normally but the spleen is overwhelming it with too much unconjugated bilirubin due to excessive breakdown of RBC’s) |
|
fluid passing through lymph nodes is exposed to what 2 things?
|
B & T lymphocytes
|
|
Starting at the cisterna chyle, navigate the lymphatics to the appropriate subclavian vein
|
Lymph from both lower limbs and the abdominopelvic viscera collects in a large sac (sometimes multiple sacs) called the --cisterna chyle--
From the cisterna chyle, the lymph flows up the --thoracic duct-- to reach the left subclavian vein. Lymph from the left upper limb and left head & neck also drains to the --left subclavian vein--. Lymph from the right upper limb and right head & neck drains to the --right subclavian vein--. |
|
a nontender, firm, enlarged lymph node would indicate what?
|
Metastatic lymphnode
|
|
most lymphatic flow from the breast travels to what node?
** |
Axillary lymph node
|
|
If lymph flow, or metastisis were to cross from one breast to another, what node would it have to cross?
|
parasternal
|
|
He had like 5 straight slides of lymphatic drainage...feel free to look at them if you want but I am not. And those were the final slides.
|
Donezo
