Study Notes
Human Organ Systems
- The human body is a biological machine made up of various organ systems.
- There are 11 organ systems: skeletal, muscular, cardiovascular, respiratory, nervous, digestive, urinary, endocrine, lymphatic, reproductive, and integumentary systems.
Biodesign
- Biodesign is the use of living organisms in design.
- It involves incorporating biological principles and materials into design.
- Biodesign is an emerging approach that draws on biological tenets and incorporates living materials into structures, objects, and tools.
Brain as a CPU System
- The brain uses electrical signals to send messages, similar to a CPU.
- The brain uses chemicals to transmit information, whereas a computer uses electricity.
- EEG (electroencephalogram) is a technique used to measure electrical activity in the brain.
- Robotic arms are used in prosthetics to mimic the movement of the human brain.
Eye as a Camera System
- The eye is composed of rod and cone cells, which are responsible for transmitting light signals to the brain.
- Optical corrections, such as glasses, contacts, and surgery, can improve vision.
- Cataract is a condition that affects the lens of the eye, leading to cloudiness and vision loss.
- Bionic eye is an electrical prosthesis that can be implanted into the eye to restore vision in people with severe retinal damage.
Heart as a Pump System
- The heart is a pump that circulates blood throughout the body.
- The right side of the heart receives blood from the body and pumps it to the lungs, while the left side receives blood from the lungs and pumps it to the body.
- The heart beats around 70-80 times per minute and is capable of pumping blood up to 30 feet in distance.
- The heart can beat over 2.5 billion times in a lifespan of 80 years.
Electrical Signaling
- The sinus node generates an electrical stimulus regularly, around 60-100 times per minute.
- The atria are activated by the electrical stimulus, which causes the heart to beat.
- ECG (electrocardiogram) is a technique used to monitor electrical activity in the heart.
Engineering Solutions for Heart-Related Issues
- Pacemakers are small devices that can be implanted into the chest to control the heartbeat.
- Pacemakers have two parts: a pulse generator and leads (electrodes).
- Defibrillators are devices that send an electric pulse or shock to the heart to restore a normal heartbeat.
- There are three types of defibrillators: AEDs (automated external defibrillators), ICDs (implantable cardioverter-defibrillators), and WCDs (wearable cardioverter-defibrillators).
