Study Notes
Course Overview
- BLG 101 focuses on the anatomy and physiology of the human body, emphasizing cells and tissues.
- Topics include homeostasis, cellular physiology, and the nucleus as the cell's control center.
Primary Tissues
- Four main types of tissues will be explored:
- Epithelial tissue
- Connective tissue
- Muscle tissue
- Nervous tissue
- The basics of the nervous system are also covered.
Assessment Format
- Quizzes consist of 10-15 multiple-choice or true/false questions.
- Each quiz is graded on a scale of 70 to 100 marks.
- Slides are essential for quizzes and midterm preparation; the textbook provides additional context.
Chemistry in Physiology
- The human body comprises numerous chemicals; chemistry underpins all physiological processes such as movement and digestion.
- Chemistry divides into two main categories:
- Basic chemistry
- Biochemistry
Basic Chemistry Concepts
-
Matter Defined:
- Matter has mass and occupies space; it can be perceived in various ways (seen, smelled, felt).
- Weight combines mass with gravitational effects.
-
States of Matter:
- Solid: fixed shape and volume.
- Liquid: adaptable shape but fixed volume.
- Gas: adaptable shape and volume.
-
Energy Classification:
- Energy enables work or movement and does not possess mass or occupy space.
- Types of energy:
- Kinetic: energy in motion.
- Potential: stored energy ready for conversion.
Energy Transformation
- Energy transitions from potential to kinetic can occur when stored energy is released to produce action.
- Forms of energy include:
- Chemical Energy: stored in chemical bonds.
- Electrical Energy: arises from moving charged particles.
- Mechanical Energy: involved in moving matter.
- Radiant/Electromagnetic Energy: travels in waves (includes heat, visible light, ultraviolet light, X-rays).
Energy Conversion Principles
- Energy can change forms, exemplified by mechanical energy from chemical reactions or electrical movement.
These notes encapsulate the essential points of BLG 101 and fundamental concepts in anatomy, physiology, and basic chemistry crucial for a foundational understanding in this course.
