Q

What separates the right and left atria?

A

Interatrial septum

17
Q

What separates the right and left ventricle?

A

Interventicular septum

18
Q

Coronary Circulation

A

It receives blood supply thru the left and right coronary arteries, and coronary veins return the oxygen-depleted blood from the heart muscle back to the heart

19
Q

What are the two main division of the Vascular System

A

Pulmonary circulation
Systematic circulation

20
Q

What is the vascular system?

A

the loop which consists of a system of blood vessels through which blood is circulated to the rest of the body

21
Q

What are the five structure of the vascular system

A

Arteries
Arterioles
Veins
Venules
Capillaries

22
Q

What consists the blood level structure?

A

A. Layer
B. Lumen
C. Valves

23
Q

What are the different layers of a blood vessels?

A

Tunica adventitia (outer connective tissue)
Tunica media (middle, muscle and elastic fiber)
Tunica intima (inner, endothelial cells)

24
Q

What are the different layers of a blood vessels?

A

Tunica adventitia (outer connective tissue)
Tunica media (middle, muscle, and elastic fiber)
Tunica intima (inner, endothelial cells)

25
Q

What are the two types of the blood cells?

A

Arterial blood
Venous blood

26
Q

It is a clear, straw-colored liquid portion of the blood which is 90% water

A

plasma

27
Q

What are the three components of the blood?

A

Erythrocytes (RBC)
Leukocytes (WBC)
Thrombocytes (platelets)

28
Q

It is inherited and determined by the antigens on the surface of the red blood cells

A

Blood type

29
Q

Why are blood type match important esp during blood type transfusion?

A

To avoid the agglutination of the RBCs when it is wrong.

30
Q

What is the purpose of ABO blood group system

A

It classifies human blood by the presence of antigens A and B and based on the antigenic components found on the surface of the RBC

31
Q

What is Hemostasis?

A

The stoppage of bleeding as a responce to an injury

32
Q

Four interrelated responses

A
  1. Vasoconstriction
  2. Formation of primary platelet
  3. Progression to the stable blood clot
  4. Fibrinolysis
33
Q

It is an enzyme that plays an important role in coagulation

A

Thrombin

34
Q

What is fibrinolysis

A

The process where the fibrin is dissolved

35
Q

It is also called the elbow pit is a triangular area on the anterior of the elbow

A

Antecubital fossa

36
Q

It is a vein arrangement that occurs in about 70% of the population

A

A

Median cubital
Cephalic
Basilix

38
Q

It is not used for routine blood collection and limited collection of arterial blood gas
