The human body is organized into a structural hierarchy that progresses from the macroscopic organismal level down to the microscopic chemical level.

Organismal Level The entire living human body.Relationship: All lower levels work together to sustain life at this highest level. 2. Organ System Level Groups of organs working together to perform major functions.Examples: circulatory, nervous, digestive systems.Relationship: The organismal level depends on the coordinated function of these systems (e.g., the respiratory and circulatory systems collaborate to deliver oxygen). 3. Organ Level Structures composed of multiple tissue types that perform specific tasks.Examples: heart, brain, liver.Relationship: Organs combine to form organ systems (e.g., the heart, blood vessels, and blood form the circulatory system). 4. Tissue Level Groups of similar cells working together to perform a function.Primary Types: Epithelial (covers surfaces), Connective (supports/connects), Muscle (contracts for movement), Nervous (transmits signals).Relationship: Tissues combine to form organs (e.g., cardiac muscle, connective tissue, and nervous tissue make up the heart). 5. Cellular Level The basic structural and functional unit of life.Examples: neurons, red blood cells, osteocytes.Relationship: Cells of the same type form tissues (e.g., muscle cells aggregate to form muscle tissue). 6. Organelle Level Specialized structures within cells that perform specific tasks.Examples: mitochondria (energy production), nucleus (DNA storage), ribosomes (protein synthesis).Relationship: Organelles work together to maintain cellular function (e.g., mitochondria power the cell, enabling tissues to function). 7. Molecular Level Molecules are formed by bonded atoms.Examples: Proteins (collagen), nucleic acids (DNA), lipids (cell membranes).Relationship: Molecules compose organelles (e.g., phospholipids form cell membranes; DNA in the nucleus directs cellular activity). 8. Chemical (Atomic) Level Atoms and their interactions.Examples: Carbon (C), hydrogen (H), oxygen (O), nitrogen (N).Relationship: Atoms bond to form molecules (e.g., H₂O, glucose), which are the building blocks for all higher levels. Summary of Structural Relationships: Organismal → Composed of organ systems. Organ systems → Composed of organs. Organs→ Composed of tissues. Tissues → Composed of cells. Cells → Contain organelles.

Part 1 (Done): Describe the levels of structural hierarchy for the human body, starting with the organismal level and ending with the chemical level. In addition, you should make sure you link each level to the previous level, emphasizing the structural relationships.
The human body is organized into a structural hierarchy that progresses from the macroscopic organismal level down to the microscopic chemical level. Each level builds upon the previous one, creating increasingly complex structures. Below is the hierarchy, from largest to smallest, with explanations linking each level to its predecessor:
1. Organismal Level
The entire living human body.
Relationship: All lower levels work together to sustain life at this highest level.
2. Organ System Level
Groups of organs working together to perform major functions.
Examples: circulatory, nervous, digestive systems.
Relationship: The organismal level depends on the coordinated function of these systems (e.g., the respiratory and circulatory systems collaborate to deliver oxygen).
3. Organ Level
Structures composed of multiple tissue types that perform specific tasks.
Examples: heart, brain, liver.
Relationship: Organs combine to form organ systems (e.g., the heart, blood vessels, and blood form the circulatory system).
4. Tissue Level
Groups of similar cells working together to perform a function.
Primary Types:
- Epithelial (covers surfaces),
- Connective (supports/connects),
- Muscle (contracts for movement),
- Nervous (transmits signals).
Relationship: Tissues combine to form organs (e.g., cardiac muscle, connective tissue, and nervous tissue make up the heart).
5. Cellular Level
The basic structural and functional unit of life.
Examples: neurons, red blood cells, osteocytes.
Relationship: Cells of the same type form tissues (e.g., muscle cells aggregate to form muscle tissue).
6. Organelle Level
Specialized structures within cells that perform specific tasks.
Examples: mitochondria (energy production), nucleus (DNA storage), ribosomes (protein synthesis).
Relationship: Organelles work together to maintain cellular function (e.g., mitochondria power the cell, enabling tissues to function).
7. Molecular Level
Molecules are formed by bonded atoms.
Examples: Proteins (collagen), nucleic acids (DNA), lipids (cell membranes).
Relationship: Molecules compose organelles (e.g., phospholipids form cell membranes; DNA in the nucleus directs cellular activity).
8. Chemical (Atomic) Level
Atoms and their interactions.
Examples: Carbon (C), hydrogen (H), oxygen (O), nitrogen (N).
Relationship: Atoms bond to form molecules (e.g., H₂O, glucose), which are the building blocks for all higher levels.
Summary of Structural Relationships:
- Organismal → Composed of organ systems.
- Organ systems → Composed of organs.
- Organs→ Composed of tissues.
- Tissues → Composed of cells.
- Cells → Contain organelles.
- Organelles → Built from molecules.
- Molecules→ Formed by atoms (chemical level).
This hierarchy illustrates how complexity emerges from simpler components, with each level's structure directly influencing its function and the function of the level above it.
Part 2: How does the principle of complementarity of structure and function apply to these structural levels? Explain and provide a specific example to demonstrate your understanding of the concept.
