Cardiovascular system
• Provides a mean of transportation
throughout the body (nutrients,
water, oxygen, hormones, and
electrolytes)
• Heart acts a pump
• Blood vessels acts a pipes

types of circulation
Pulmonary Circulation
involves the lungs to get
oxygen and load off carbon
dioxide
Systemic Circulation
involves the rest of the body
to deliver oxygen and to collect
carbon dioxide

anatomy of the heart
•About the size of the fist
•Located in the mediastinum, slightly
left of the midline
•Apex - pointed tip
- 5th intercostal space
•Base - 2nd rib

•Atria - upper chambers
•Ventricles - lower chambers
•Valves - directs the blood flow in
one direction
 separate the atrium and
ventricle
 separate the chambers to
major blood vessels
•Atrioventricular septum -
separates the left and right
chambers of the heart

great vessels
• Superior Vena Cava
• Inferior Vena Cava
• Aorta
• Pulmonary Arteries
• Pulmonary Veins
Superior Vena Cava
Pulmonary
Veins

layers of the heart
1.Endocardium - inner layer
2.Myocardium - muscular
layer
3.Pericardium - double layer
that covers the outside of the
heart
a) Visceral Pericardium -
adhered to the heart
b) Parietal Pericardium -
adhered to the chest
wall

Vena Cava
delivers deoxygenated
blood back to the heart
Right Atrium
receives deoxygenated
blood from the vena cava
Tricuspid Valve
separates the right atrium
and right ventricle

Annulus
 a fibrous ring that
serves as circumferential
attachment of the valves
Chordae Tendineae
 “cordlike tendon”
attachment of the cusp of
the valves

electrical conduction of the heart
Generates electrical energy
that stimulates the contraction
of the heart muscle
(myocardium)

electrical conduction of the heart

electrocardiography (EKG,ECG)
• Recording of the electrical activity of the heart
• Indication for ECG usage:
 Symptoms of myocardial infarction
 Symptoms of pulmonary embolism
 Cardiac murmurs
 Syncope or collapse
 Seizures
 Perceived cardiac dysrhythmias

waves of ECG
• P wave
 activation of the atria
• QRS complex
 activation of the ventricles
• T wave
 recovery of the ventricles
• U wave
recovery of the
interventricular septum

Anatomy of the blood vessels
from heart to heart
