6. Medical Electronics
A branch of study in which electronic
instruments & equipment's used for
medical applications.
Such as Diagnosis, Therapy research,
cardiac control, Anesthesia control,
surgery and furthermore.
Equipment is the machine that's processing the work and the instrument is
to measure the data that comes out of the machine to get feed back of the
machine and the process.

8. Human Body
• Human body is a complex engineering wonder, which contains various types of
systems such as electrical, mechanical, hydraulic, pneumatic, chemical, thermal etc.
• These systems communicate internally with each other and also with an external
environment.
• By means of a multi-level control system and communication network, the individual
systems enable the human body to perform useful tasks, sustain life and reproduce
itself.

9. PHYSIOLOGICAL SYSTEMS OF HUMAN BODY
1) The Skeletal System - Bones & joints
2) Muscular System - Skeletal muscle
3) Nervous System - Brain, spinal cord & nerves
4) Endocrine System - Hormone-producing cells & glands
5) Cardiovascular System - Blood, heart & blood vessels
6) Respiratory System - Lungs & airways
7) Digestive System - Organs of the gastrointestinal tract
8) Urinary System - Kidneys, bladder and ureters
9) Reproductive System - Male and Female reproductive organs
10) The Integumentary System - The skin & derived structures
11) Lymphatic & Immune System - Lymphatic vessels & fluid

11. SourcesofBioMedical
Signals
• Biomedical signals are those signals (phenomenon that conveys
information) which are used primarily for extracting information
on a biological system under investigation.
• The process of extracting information could be as simple as feeling
the pulse of a person on the wrist or as complex as analyzing the
structure of internal soft tissues by an ultrasound scanner.

12. SOURCES OF BIOMEDICAL SIGNALS
Biomedical signals are those signals
which are used primarily for extracting
information on a biological system
under investigation.
Classification of Bio Medical Signals
• Bio-Electric Signals
• Bio-Acoustic Signals
• Bio-Mechanical Signal
• Bio-Chemical Signals
• Bio-Magnetic Signal
• Bio-Optical Signals
• Bio-Impedance Signals
