Exam 3 Materials Flashcards
% and function?
- Lymphocytes (20-40%)
- Second most common
- Long term immunity
- Make antibodies
Albumin
- Plasma protein, most common
- Keeps water in blood and makes it thicker
Tunica Intima (interna)
- Made of endothelium** (**simple squamous epithelium)
- Inner most layer
- Lining inside of vessels
Tunica Externa (Adventitia)
- Most superficial layer
- Anchors blood vessels to organs
- Thickest in veins
Erythrocytes %?
44%
Myeloid Stem Cells
They become:
Erythrocytes
Platelets
Leukocytes (4 of them)
What is Tunica Media made of?
Smooth (involuntary) muscle
Globulins
- Plasma protein, 2nd most common
- Contains antibodies to fight off pathogens
Fibrogens
- Plasma Protein
- Helps with blood clotting
Coronary Sinus
The large veins that the coronary arteries drain into to return to heart
Structure and function of Erythrocytes?
- Mature RBC lack nuclei/organelles
- Biconcave (for more surface area)
- Pass thru blood vessel single file
- Carries 280 million hemoglobin
What vein accompanies Right Marginal Artery? What parts of the heart does it supply?
- Small Cardiac Vein
- Supplies right border of heart
Muscular Arteries
-Medium sized arteries
- Thick tunica media
- Goes to different organs in body
- Direct blood flow
Aortic Arch branches off into?
-
Brachiocephalic trunk
- Bifurcates into right common carotid** and **right subclavian** **arteries
- Left common carotid
- Left subclavian arteries
% and function?
- Monocytes (Agranulocytes 2-8%)
- Common in chronic infection
- Become macraophages (more robust)
% and function?
- Neutrophils (50-70% most common)
- Bacteria slayers (through phagocytosis)
How much does plasma make up blood?
55%
Where vein accompanies the Anterior Interventricular Artery? What parts of the heart does it supply?
- Great Cardiac Vein
- Supplies anterior** surfaces of **both ventricles** and **interventricular septum
Left ventricles pumps into ascending aorta which branches off into?
Left coronary artery
Right coronary artery
Vasa Vasorum
- Smaller arteries that supply blood through tunica externa
- Basophils (0.5-1%)
- Produces histamine (swelling)
What are the components of plasma?
Water 92%
Plasma protein 7%
Other solutes 1%
Right coronary Artery branches off to?
- Right Marginal Artery
- Posterior Interventricular Artery
What is Tunica externa (adventitia) made of?
Connective tissue layer
Chemotaxis
-Attracts WBC to site of infection from damaged cells
Where does the Circumflex artery go? What parts of the heart does it supply?
- Goes around and behind heart
- Supplies left atrium and ventricle
Left coronary artery branches off to?
- Circumflex artery
- Anterior Interventricular Artery
Buffy Coat %? Componenets?
- <1%
- Leuokocytes and platelets
What vein accompanies Posterior Interventricular Artery? What parts of the heart does the artery supplies?
- Middle Cardiac Vein
- Posterior surfaces of right and left ventricle
Elastic Arteries
- Largest arteries
- Ability to expand/contract (elastic fibers)
Hemocytoblasts
Main stem cells that produces blood
Diapedesis
- Allows leukocytes to leave blood vessels and enter tissues
Lymphoid Stem Cells
Only become lymphocytes
Tunica Media
- Controlled by sympathetic (vasoconstriction) and parasympathetic (vasodilation) input
- Thickest in arteries
% and function?
Esinophils (1-4%)
- Reduce swelling (antihistamine)
- Fights worms
