Course: Bio 107 Lecture 5 Review 2025
Instructor: Anthony Phillips
Core Materials to Consult:
Lecture Content
Lecture Slides
Lecture Guide (All inclusive)
Textbook Specific Readings
Lab-book (no specific requirements for this instructor)
Utilization Guidelines:
Use lecture slides for comprehensive core content
Specific readings augmenting lecture material
Be mindful of discrepancies between lectures and textbook readings
When in doubt, rely on lecture slides and discussed content
Important Note: Clinical examples included for relevance; only content from lectures and slides required for exam.
Integrative Learning: Combine facts from slides and lectures to interpret questions.
Scoring Criteria:
A: Full understanding
B: Basic integration
C: Minimal integration
Eleven Body Systems: Understand composition and organ roles:
Integumentary
Muscular
Skeletal
Nervous
Endocrine
Lymphatic and Immune
Cardiovascular
Respiratory
Digestive
Urinary
Reproductive
Example: Pancreas functions in both digestive and endocrine systems.
Primary Functions:
Brings lymph fluid with lymphocytes to veins of cardiovascular system.
Engulf pathogens and stimulate immune response.
Components:
Lymphatic vessels
Lymphatic fluid, B & T cells
Lymph nodes monitor lymph composition
Spleen recycles red blood cells and produces immune responses
Thymus: Development of T cells.
Lymphatic ducts empty lymph into cardiovascular system (subclavian veins).
Key Point: Afferent vessels carry lymph to lymph nodes; efferent vessels carry lymph away.
Note: No need to memorize specific lymphatic names.
Glands and Functions:
Pineal gland: Regulates sleep through melatonin.
Hypothalamus/Pituitary: Controls multiple glands, regulates growth and fluid balance.
Thyroid gland: Metabolic rate control through thyroxine.
Parathyroid gland: Calcium level regulation.
Adrenal glands: Stress response, metabolism regulation.
Pancreas: Glucose control.
Gonads: Sexual characteristics and reproduction.
General knowledge on hormone activity is sufficient; detailed specifics are unnecessary.
Columnar Types: Recognize features like ciliated versus non-ciliated and presence of goblet cells.
Transitional Epithelium: Found in bladder; exhibits stretched and relaxed states.
Stratified Types: Understand differences in appearance under various conditions.
Types:
Endocrine: Directly secretes into blood (e.g., pancreas).
Exocrine: Uses ducts to release substances onto epithelium surfaces (sweat, saliva).
Mixed glands can have both types of secretion.
Comprised of Extracellular Matrix (ECM) + Cells.
Key components:
Ground Substance (water, proteins, polysaccharides)
Protein Fibers (collagen, reticular, elastic).
Importance of ECM structure relates to tissue function (e.g., soft vs. hard connective tissues).
Muscle Types: Striated (skeletal, cardiac) vs. non-striated (smooth).
Nerve Components: Discusses role of neuroglia in supporting and insulating neurons.
Review queries focusing on body systems, histology, and connective tissues.
Practice critical thinking by evaluating multiple-choice statements.
Best Wishes: Encouragement for students to excel in their upcoming assessments and to maintain contact with faculty for support.
Key texts: Tortora and Derrickson editions highlighted.
