Study Notes
Main Branches of Natural Science
- Physical Science studies non-living matter.
- Life Science (or Biology) studies living organisms.
Philosophers' Debates on Scientific Approaches
- Francis Bacon argued for the importance of experimentation in natural science.
- Rene Descartes advocated for the use of mathematics and logic.
Mechanisms for Validating Scientific Advances
- Peer Review involves impartial experts evaluating scientific work.
- Replication of experiments ensures consistency and accuracy.
Alternative Name for Life Science
- Biology.
16th Century Scientific Developments
- Natural History emerged, focusing on classifying and describing the natural world.
Divisions of the Circulatory System
- Pulmonary Circulation carries blood to and from the lungs.
- Systemic Circulation transports blood throughout the body.
Components of Blood
- Red blood cells (erythrocytes) transport oxygen.
- White blood cells (leukocytes) defend against infection.
- Platelets help with blood clotting.
- Plasma, the liquid component, carries blood cells, nutrients, and waste products.
Great Vessels of the Heart
- Aorta - the main artery carrying oxygenated blood from the heart.
- Vena cava - the large vein carrying deoxygenated blood back to the heart.
- Pulmonary arteries - carry deoxygenated blood to the lungs.
- Pulmonary veins - carry oxygenated blood from the lungs to the heart.
Alternative Name for the Cardiovascular System
- Circulatory System.
Function of the Circulatory System
- Delivers oxygen and nutrients to the body's cells.
- Removes carbon dioxide and waste products.
- Helps regulate body temperature.
