Introduction to Human Biology

These flashcards cover key concepts from the Introduction to Human Biology lecture notes, focusing on anatomy, physiology, homeostasis, and body organization.

What are the key areas of focus when distinguishing between anatomy and physiology?

Anatomy is the study of body structures, while physiology is the study of the functions of those structures.

What are the six levels of structural organization in the human body?

Atoms, Molecules, Organelles, Cells, Tissues, Organs, Organ systems, Organism.

What is homeostasis?

Homeostasis is the maintenance of a stable internal environment within the body.

What are the three components involved in homeostatic regulation?

Receptor, Control Center, Effector.

What is the principle of complementarity?

Anatomy and physiology are interrelated; the structure of a body part determines its function.

What is an example of a negative feedback mechanism in the human body?

Body temperature regulation.

What is the anatomical position?

The body standing upright with feet at shoulder width, and palms and toes facing forward.

What are the main types of feedback mechanisms in homeostasis?

Negative feedback and Positive feedback.

What is the importance of the serous membranes?

They cover the walls and organs in the thoracic and abdominopelvic cavities, reducing friction.

List the four abdominopelvic quadrants.

Right Upper Quadrant (RUQ), Left Upper Quadrant (LUQ), Right Lower Quadrant (RLQ), Left Lower Quadrant (LLQ).
