Key Concepts and Definitions

Levels of Organization

The human body is organized into hierarchical levels, each with increasing complexity:

Chemical Level: Atoms and molecules essential for life (e.g., water, proteins, DNA).
Cellular Level: Cells are the basic structural and functional units of life.
Tissue Level: Groups of similar cells performing a common function (e.g., muscle tissue).
Organ Level: Structures composed of two or more tissue types (e.g., heart, bone).
Organ System Level: Groups of organs working together (e.g., skeletal system).
Organismal Level: The complete living being.

Homeostasis

Homeostasis is the maintenance of a stable internal environment despite changes in external conditions. It is essential for survival and function.

Example: Regulation of body temperature, blood glucose levels, and pH.
Mechanisms: Usually maintained by negative feedback loops.

Negative Feedback Example:

Stimulus: Increase in body temperature
Receptor: Thermoreceptors detect change
Control Center: Hypothalamus
Effector: Sweat glands increase activity
Response: Body temperature decreases

Basic Chemistry & Biochemistry

Atoms: Smallest units of matter, composed of protons, neutrons, and electrons.
Molecules: Combinations of atoms (e.g., H2O, CO2).
Macromolecules: Large molecules essential for life (proteins, lipids, carbohydrates, nucleic acids).
Metabolism: All chemical reactions in the body, including catabolism (breaking down) and anabolism (building up).

Cells and Cellular Metabolism

Cell: The basic unit of structure and function in living organisms.
Organelles: Specialized structures within cells (e.g., nucleus, mitochondria).
Cellular Metabolism: Includes processes such as glycolysis, Krebs cycle, and oxidative phosphorylation.
Key Equation:

This equation represents cellular respiration, the process by which cells generate energy (ATP) from glucose and oxygen.

Tissues

Epithelial Tissue: Covers body surfaces and lines cavities.
Connective Tissue: Supports, protects, and binds other tissues (e.g., bone, blood).
Muscle Tissue: Responsible for movement (skeletal, cardiac, smooth).
Nervous Tissue: Transmits electrical impulses for communication.

Major Organ Systems Covered

Integumentary System: Skin, hair, nails; protects body and regulates temperature.
Skeletal System: Bones, joints; provides support, protection, and movement.
Muscular System: Skeletal muscles; enables movement and posture.
Nervous System: Brain, spinal cord, nerves; controls and coordinates body activities.

Assessment and Grading

Exams: Five lecture exams and three lab exams, covering the topics above.
Grading Scale:

Percentage	Letter Grade
90% - 100%	A
80% - 89%	B
70% - 79%	C
60% - 69%	D
< 60%	F
