Cardiovascular System - Guangyuan Pan Period 2
Major functions of the cardiovascular system
Capillaries
A vessels that run between the arteries and veins
Pulmonary circuit
Oxygen-poor blood is carried to the lungs and picks up oxygen and drop off carbon dioxide.
Veins
Transport blood toward to the heart.
Systemic circuit
It sends oxygen. rich blood to all body cells where it drops of the oxygen and picks up carbon dioxide.
Arteries
Transport blood away from the heart
Anatomy of the heart
Valves
Pulmonary valve
Mitral (bicuspid) valve
Tricuspid valve
Aortic valve
Chambers
Right
Right Atrium
Right Ventricle
Left
Left Ventricle
Left Atrium
ABO, Rh blood types
AB blood
Antigen A and B
Neither A/B
O blood
Neither A/B
Antibody A & B
B blood
Antigen B
Antibody A
If blood has Antigen D = RH positive.
If blood doesn't have Antigen D = RH negative
A blood
Antibody B
Antigen A
Layers of the heart
Myocardium
Middle layer
Endocardium
Innermost Layer
Epicardium
Outermost layer
Blood flow through the heart and body

Blood flow through the body
After the blood goes through the heart it then goes up to your head and goes all throughout your body. When it cycles back, it goes into the Superior/Inferior vena cava and does the blood flow in the heart once again.
Cardiac cycle and the ECG
Removes the waste products of metabolism to the organ that disposes of those wastes
Protects the body from infections
Gives cells nutrients
Blood clots stop bleeding from injuries
Circulates Oxygen and removes Carbon Dioxide
Sends hormones to target cells and organs
Regulates body temperature
Major blood vessels
Aorta
Superior Vena Cava
Inferior Vena Cava
Pulmonary Artery
Vital signs
BP is not greater that 120/80 at rest is considered normal
Cardiac output
Stroke volume
Amount of blood discharged from each ventricle with each
contraction
Heart rate
number of heart beats per minute
Affect BP
Arterial blood pressure
Systolic Pressure
max arterial pressure reached during ventricular contraction
Diastolic prtessure
Minimum arterial pressure reached during ventricular relaxation
The alternating expansion and recoil of wall of an artery as the ventricles contract and relax can be felt at a certain point in the body as a pulse
BP moves blood through lumen of arteries and arterioles
Common pulse point = radial artery
Disorders of the cardiovascular system
Heart disease
A problem in one or more parts of the heart.
Abnormal heart rhythms
Your heart beast out of rhythm.
Heart failure
Your heart doesn't pump as strongly as it should.
Aorta disease
The aorta widens or tears.
Vascular disease
A condition that affects your circulatory system.
Stroke
Something that slows or blocks blood flow to your brain.
Major components and functions of Blood
Formed elements
Platelets
RBC
WBC
Neutrophils
Has 50-7 0% of leukocytes
Eosinophils
Make up 1-3% of circulating leukocytes
Basophils
Has <1% of leukocytes
Monocytes
Make up 3-9% of circulating leukocytes
Lymphocytes
Live many years and has 25-33% of circulating leukocytes
Plasma
Electrolytes
Water
Proteins
Albumin
Globulins
Fibrinogen
Wates
Nutrients/Hormones/Vitamins
Gasses
N2
O2
CO2
Function
Blood transports substances throughout the body, helps to
maintain homeostasis and distributes heat
Blood transports nutrients and oxygen to the body cells, and
removes metabolic wastes and carbon dioxide
