Q

Thoracic duct

A

the largest lymph duct in the human body. 3/4 of the lymph in the body drains through this duct. Lymph coming from the left upper extremities, left side of the head and neck, left side of the chest, the entire abdominal cavity, and both lower extremities will drain through this duct.

25
How many liters of blood are in an adult body
4.5 liters
26
Viscosity
a measure of the resistance to flow of a liquid (thickness) Blood moves 4.5 to 5.5 times viscus (slower) than water
27
Temperature
normal body temperature is 98.6 F, 37 C; blood is 100.3 F, slightly warmer than normal body temperature
28
Plasma
55% (Liquid portion) of non- clotted blood, slightly amber or straw color.
29
Corpuscles
formed elements) 45% of whole human blood
30
What are the components of plasma?
92% water | 8% Dissolved substances
31
Blood proteins
Serum albumin Serum globulin Fibrinogen
32
Serum Albumin
protein naturally dissolved in plasma portion of blood
33
Serum Globulin
blood protein naturally found in plasma
34
Fibrinogen
blood protein present in blood plasma which will form the fibrous network when blood clot forms
35
Inorganic salts
NA – salt / K- potassium / Ca – calcium / Mg -magnesium
36
Nutrients
Food glucose - (blood sugar) / lipids - fats
37
Waste Products
urea - the primary constituent of urine ammonia
38
Respiratory gases
o2 - Oxygen / Co2 -Carbon dioxide / N2 - Nitrogen
39
Hormones
component of plasma
40
Antibodies
dissolved within the plasma portion of blood.
41
Essential clotting
factors called Factor E
42
Enzymes
(ASE) speed up the rate of a chemical reaction and not used up in the process.
43
Erythrocytes (Red Blood Cells)
biconcave discs shaped, non-nucleated, 4.5-5 million per cu. Mm of blood; crenation (shrink) hypertonic solution and hemolysis (bursting) hypotonic solution; originate in bone marrow 120 day life span normally; destroyed in the liver & spleen; The only function is to carry hemoglobin.
44
Leukocytes (white blood cells)
least # of blood cells; 5,000 – 9,000 per cu. Mm of blood, most numerous types (5 different types);defense of the body against infection by diapedesis (WBC ability to squeeze thru pores/capillaries) and phagocytosis (cell ingestion, WBC will attempt to surround and ingest anything foreign) when destroyed it forms puss
45
Agranulocytes
WBC’s which have absence of granules within protoplasm
46
Lymphocytes
one large central nucleus - this cell in humans is responsible for producing antibodies.
47
Monocytes
rid body of pus
48
Granulocytes
WBC’s which contain granules within protoplasm
49
Neurophils
granules stain neither red or blue (neutral), most numerous of type of WBC in humans, 65% of WBC; its function to performs phagocytosis - ingest, surrounds, and destroys anything foreign.
50
Eusinophils
granules of WBC that stain red
51
Basophils
granules of WBC that stain blue. Responsible for allergic reactions
52
Functions of white blood cells - defend the body against infection through:
Diapedesis Tissue repair Absorption of fat Formation of blood proteins
53
Thrombocytes (platelets)
fragmented cells; 3,000 per cu. Mm; normal coagulation time is 3-5 minutes; plasma vs serum
54
Plasma
liquid portion of non-clotted blood 92% H2O
55
Serum
the liquid portion of blood left over after blood has clotted.
56
Fibrinogen
when blood clots, the central clotting factor that were present and dissolved in the plasma portion have been used up in the clotting process; 3-5 minutes; smallest in size 3 - 4 microns, disc shaped; 300,00 per cu. mm; Origin - bone marrow.
57
Substances in blood that by themselves will promote blood clotting.
i. THROMBOPLASTIN – cephalin or thrombosinase ii. PROTHOMBIN iii. CALCIUM iv. FIBRINOGEN – forms boundaries of latticework
58
Substances in blood that inhibit clotting
i. ANTITHROMBIN | ii. ANTIPROTHROMBIN (HEPRIN)
59
FUNCTION OF BLOOD:
a. Transport–O2,CO2,food,waste,hormones b. Temperatureregulation–98.6 c. Control of pH – 7.3 to 7.4 d. Control of water balance – 92% of plasma is H2O, can’t lose more than 1⁄2 or death e. Defense against infection – by leukocytes (5)
60
Chemistry of clotting blood.
a) Fragmentation of platelets released a chemical called thromboplastin. b) Thrombaptastin neutralizes antiprothrombin, thus liberating prothrombin. c) Prothrombin unites with calcium to form thrambin. d) Thrambin and fibrinogen from fibrin. e. Fibrin and blood cells form the clot within three to five minutes.
