Study Notes
Circulatory System
- Responsible for the transportation of blood throughout the body.
- Heart: Central organ functioning as a pump, facilitating blood circulation.
- Veins: Blood vessels that transport deoxygenated blood back to the heart.
- Arteries: Blood vessels that carry oxygenated blood away from the heart to various body tissues.
Digestive System
- Involved in breaking down food and extracting essential nutrients for the body.
- Mouth: The entry point for food; initiates the digestive process through chewing and saliva.
- Stomach: Organ where most of the chemical digestion occurs, aided by gastric juices.
- Small intestine: Key site for nutrient absorption; lined with villi to increase surface area for maximum absorption.
- Large intestine: Responsible for absorbing excess water from food waste, forming solid waste (feces) for excretion.
Excretory System
- Critical for eliminating waste products resulting from metabolism, thus maintaining homeostasis.
- Kidneys: Pair of organs that filter blood to remove waste substances and regulate water balance, producing urine in the process.
