2.01 Remember the structures of the circulatory system
Blood One drop of blood contains: 5 million RBCs 250, ,000 platelets 7,500 WBCs Red blood cells live 120 days. Make new blood cells 2 million per second! 2.01 Remember the structures of the circulatory system

Structures of the blood
Plasma Erythrocytes Leukocytes Thrombocytes 2.01 Remember the structures of the circulatory system
7
2.01 Remember the structures of the circulatory system
Plasma Straw-colored liquid 55% of the blood’s volume Water Plasma proteins Nutrients Electrolytes Hormones, vitamins, and enzymes Waste products Plasma Cellular elements 2.01 Remember the structures of the circulatory system

2.01 Remember the structures of the circulatory system
Leukocytes Larger than erythrocytes Five types Leuk/o/cytes – white cells 2.01 Remember the structures of the circulatory system
11
2.01 Remember the structures of the circulatory system
Leukocytes Agranulocytes Lymphocytes Monocytes 2.01 Remember the structures of the circulatory system
12
2.01 Remember the structures of the circulatory system
Leukocytes Granulocytes Neutrophils Eosinophils Basophils 2.01 Remember the structures of the circulatory system
13
2.01 Remember the structures of the circulatory system
Thrombocytes Smallest of solid components of blood Synthesized in red marrow Not cells, composed of fragments of megakaryocytes Necessary for the initiation of the blood clotting process 2.01 Remember the structures of the circulatory system
14
2.01 Remember the structures of the circulatory system
Life span of blood cells... 2.01 Remember the structures of the circulatory system
15
Blood types Inherited from parents
What are the types of blood? Inherited from parents Determined by presence or absence of an antigen on the surface of the red blood cell 2.01 Remember the structures of the circulatory system
16
Check your knowledge of medical history...
In 1901, the Austrian immunologist Karl Landsteiner discovered that blood may be grouped into four main types. Based on the reaction that resulted when blood from different individuals were mixed. 2.01 Remember the structures of the circulatory system
17
2.01 Remember the structures of the circulatory system
Blood types Someone with type A antigen has B antibodies Someone with type B antigen has A antibodies Someone with type AB antigen has no antibodies Someone with type O antigen has A and B antibodies 2.01 Remember the structures of the circulatory system
18
2.01 Remember the structures of the circulatory system
Rh factor Rhesus (Rh) factor is an inherited trait that refers to a specific protein found on the surface of red blood cells (antigen). Blood used in transfusions must match donors for Rh status as well as for ABO blood type. Although Rh factor doesn't affect the patient’s health, it can affect pregnancy. 2.01 Remember the structures of the circulatory system
19
2.01 Remember the structures of the circulatory system
Rh factor In 1940, the Rh factor was discovered as a result of studying Rhesus monkeys. When blood from monkeys was injected into rabbits and guinea pigs, it clotted. 2.01 Remember the structures of the circulatory system
20
2.01 Remember the structures of the circulatory system
Rh factor If the blood has the protein, the patient is Rh positive. If the blood lacks the protein, the patient is Rh negative. Did you know??? 2.01 Remember the structures of the circulatory system
21
Structures of the circulatory system
Heart Did you know your heart is the size of your fist? 2.01 Remember the structures of the circulatory system
22
Heart Can you identify the structures of the heart? The heart is a
double pump. 2.01 Remember the structures of the circulatory system
23
2.01 Remember the structures of the circulatory system
Heart Check your knowledge... Aorta Superior vena cava Pulmonary artery Aortic semilunar valve Pulmonary vein Right atrium Left atrium Tricuspid valve Bicuspid (mitral) valve Inferior vena cava Pulmonary semilunar valve Right ventricle Left ventricle Septum Apex 2.01 Remember the structures of the circulatory system
24
2.01 Remember the structures of the circulatory system
Layers of the heart Left atrium Right atrium Pericardium Myocardium Endocardium Right ventricle Left ventricle 2.01 Remember the structures of the circulatory system
25
Conduction system of heart beats
Refer to your textbook to identify the structures of the heart’s conduction system in the correct sequence for the heart to beat. 2.01 Remember the structures of the circulatory system
26
Structures of the circulatory system
ARTERIES 2.01 Remember the structures of the circulatory system
27
Vessels of the circulatory system
ARTERIES Carry oxygenated blood away from the heart to the capillaries Elastic, muscular and thick-walled Transport blood under very high pressure Arteries > arterioles > capillaries 2.01 Remember the structures of the circulatory system
28
Vessels of the circulatory system
Arteries Arterial blood Oxygen rich Bright red, spurts 2.01 Remember the structures of the circulatory system
29
Structures of the circulatory system
VEINS 2.01 Remember the structures of the circulatory system
30
Vessels of the circulatory system
VEINS Carry deoxygenated blood away from capillaries to the heart Veins contain a muscular layer, but less elastic and muscular than arteries Thin walled veins collapse easily when not filled with blood Veins have values that permit flow of blood only in direction of the heart Veins > Venules > Capillaries 2.01 Remember the structures of the circulatory system
31
Vessels of the circulatory system
Veins Venous blood Oxygen poor Dark crimson, oozes 2.01 Remember the structures of the circulatory system
32
Vessels of the circulatory system
Identify the major arteries. Identify the major veins. 2.01 Remember the structures of the circulatory system
33
Structures of the circulatory system
Capillaries The smallest blood vessels Connect arterioles to venules 2.01 Remember the structures of the circulatory system
34
Structures of the circulatory system
Trace the flow of blood through the body 2.01 Remember the structures of the circulatory system
35
Flow of blood through the body
Right side Superior vena cava Inferior vena cava Right atrium Tricuspid valve Right Ventricle Pulmonary valve Pulmonary artery Lungs CO2 and O2 exchange Left Side Pulmonary vein Left atrium Bicuspid valve Left ventricle Aortic valve Aorta Body 2.01 Remember the structures of the circulatory system
36
2.01 Remember the structures of the circulatory system
Pulse sites Alternating expansion and contraction of an artery as blood flows through it. Radial Temporal Brachial Ulnar Facial Carotid Popliteal Femoral tibialis dorsalis pedis 2.01 Remember the structures of the circulatory system
37
Common pulse sites Practice locating pulse sites...
