Study Notes
Circulatory System
- The heart is the primary organ responsible for pumping blood throughout the body.
- It consists of four chambers: two atria and two ventricles, which work collaboratively to circulate oxygenated and deoxygenated blood.
Musculoskeletal System
- The skeletal muscles are essential for movement, allowing the body to perform voluntary actions.
- The vestibular system, located in the inner ear, is crucial for balance and spatial orientation.
Digestive System
- The stomach and intestines are vital organs in the digestive process.
- The stomach chemically breaks down food, while the small intestine absorbs nutrients, converting them into energy for the body.
Visual System
- The eyes, specifically the retina, detect light and enable vision.
- Rods and cones within the retina convert light into electrical signals sent to the brain for image processing.
Protective System
- The ribcage plays a significant role in protecting vital internal organs like the heart and lungs.
- Bones and other structures also provide a protective framework for organs against physical trauma.
