30
Which of the following is the innermost layer of a blood vessel
Tunica intima Tunica media: middle layer with smooth muscles Tunica externa: outer layer with connective tissue sheath Tunica intima: inner layer with endothelial lining and surrounding layer of connective tissue
31
Which of the following is true of basophils?
Attract other defense cells Constitute about 1 percent of WBCs Granules contain heparin Granules contain histamine
32
Which of the following is not true of monocytes?
About the same size of basophils ``` What is true: Become macrophages Long lives Enter tissues and wander Can phagocytize bacteria ```
33
Which of the following statements about blood is false?
The normal Ph of blood is 6.8 to 7.0 ``` What is right: Blood contains buffers that control pH Cells in blood compromise the formed elements Blood is about 55 percent plasma Blood is more viscous than water Normal ph is between 7.35-7.45 ```

39
Which of theses would cause stroke volume to increase?
When diastolic blood pressure is decreased
40
Which of these is true about the atrial reflex?
Depends on sympathetic innervation Also called bainbridge reflex Triggered by increasing venous return Triggered by atrial mechanoreceptors
41

Veins
43

Albumin
44

Basophils
45
White blood cells that are increased in allergic individuals are the
Eosinophils
46
With each ventricular systole,
Blood pressure increases
47

Monocytes
48

Anemia
49

50
Blood
A specialized fluid connective tissue that contains cells suspended in a fluid matrix.
51
Hematocrit
The percentage of formed elements in a sample of blood.
52
Plasma
Fluid matrix that makes up 55%. | It has plasma proteins (7%) other solutes and water which water makes up 92%.
53
Formed elements
Blood cells and cell fragments that’s are suspended in plasma. These are white blood cells, platelets and red blood cells
54
Erythrocytes or red blood cells
Most abundant blood cells. These specialized cells are essential for transport of oxygen in blood
55
White blood cells or leukocytes
Play a role in the body’s defense mechanisms. There are 5. Lads of leukocytes, neutrophils,esoinophils, basophils, lymphocytes, and monocytes.
56
Albumins
60% of plasma protein. Most abundant. Major contributors to the osmotic pressure of plasma. Transporting fatty acids and hormones
57
Globulins
35% of proteins in plasma. Antibodies(immunoglobulin), attack foreign proteins and pathogens.
58
Fibrinogen
Functions in clotting.
59
Hemoglobin
Developing red blood cell loses any organelle not directly associated with the cells primary function. Make up 95 percent of it intracellular proteins. • responsible for the cells ability to transport oxygen and carbon dioxide
60
Vascular phase
Cutting the wall of a blood vessel triggers a contraction in the smooth muscle fibers of the vessel wall. Vascular spasm(decreases diameter of vessel at site of injury) lasts about 30 min, this is vascular phase
61
Platelet phase
Attachment of platelets to sticky endothelial surfaces, to the basement membrane and to exposed collagen fibers.
62
Coagulation phase
Blood clotting, does not start until 30 seconds or more after the vessel has been damaged.
