Study Notes
Cell Structure and Function
- Cells are the fundamental units of all living things.
- Cell theory outlines the key principles of cells.
- Key organelles and their functions include:
- Nucleus: Controls cell activities.
- Cell membrane: Regulates what enters and exits the cell.
- Vacuole: Stores water and other substances.
- Chloroplast: Site of photosynthesis in plant cells.
- Mitochondria: Powerhouse of the cell, produces energy.
- Cytoplasm: Jelly-like substance filling the cell.
- Cell Wall: Rigid outer layer, supports plant cells.
- Specialized structures exhibit unique functions, depending on the cell's role.
- Understanding the importance of each cell part is crucial.
- Identify cell structures and organelles from diagrams.
Introduction to Body Systems
Respiratory System
- Main organs include lungs and airways.
- Responsible for gas exchange, taking in oxygen and releasing carbon dioxide.
- Crucial for oxygen transport throughout the body.
- Identifying the purpose of the respiratory system is essential.
Digestive System
- Organs involved include mouth, esophagus, stomach, intestines, etc.
- Breaks down food into absorbable nutrients.
- Facilitates nutrient absorption.
- The purpose of the digestive system is nutrient breakdown and absorption.
Circulatory System
- Heart, blood vessels (arteries, veins, capillaries), and blood are essential.
- Transports oxygen, nutrients, and waste products throughout the body.
- The function of the circulatory system is transport.
Excretory System
- Kidneys, bladder, and other organs remove waste products from the blood.
- Maintains the body's internal balance (homeostasis).
- The excretory system's function is waste removal.
Nervous System
- Brain, spinal cord, and peripheral nerves facilitate communication, response to stimuli, and adaptation to environmental changes.
- The nervous system's purpose is communication and response to changes.
Systems and Your Health
- Blood composition includes red blood cells, white blood cells, and platelets.
- A sphygmomanometer measures blood pressure (differing from a stethoscope which detects internal sounds).
- Blood pressure indicates the force of blood against artery walls.
- Common causes of circulatory disorders include high blood pressure and heart disease.
- A healthy diet comprises various essential nutrients.
- Cilia are tiny hair-like structures found in various systems, promoting movement.
