Study Notes
Human Biology - Introduction
- Biology is the study of life in all its aspects, including living and non-living components, morphology, physiology, anatomy, behavior, origin, and distribution.
- Biology has many branches, including:
- Anatomy: Study of the basic structure of organisms and their parts.
- Histology: Study of microscopic tissue structure.
- Cytology: Study of cell structure and function.
- Physiology: Study of the normal functions of living organisms.
- Embryology: Study of the development of embryos.
- Genetics: Study of inherited characteristics and variation.
- Molecular Biology: Study of biology at a molecular level (e.g., DNA, RNA).
- Biochemistry: Study of chemical nature and processes in organisms.
- Zoology: Study of animal behavior, structure, physiology, classification, and distribution.
- Botany: Study of plants.
- Microbiology: Study of microorganisms.
- Evolution: Study of the development of highly organized species from lowly organized ones through gradual change.
- Ecology: Study of interactions between organisms and their environment.
- Entomology: Study of insects.
Human Biology
- Human biology studies human anatomy, growth, nutrition, reproduction, respiration, digestion, excretion, and secretion.
- This involves studying the human body's systems and organ functions.
- The human body is organized in different levels from atoms to cells, tissues, organs, and organ systems, with increasing complexity at each level.
- The human body's organization ensures efficient operation of complex functions through the interaction of various parts and systems.
- Main elements in the human body are hydrogen, oxygen, carbon, calcium, and phosphorus. Electrolytes in body fluids include sodium, chloride, and potassium.
- Human body is composed of approximately 100 trillion cells by adulthood.
Cells
- Cells are the basic units of structure and function in the human body.
- Different types of cells are specialized in shape and function (e.g., nerve cells, muscle cells).
- Cells carry out essential life functions for survival.
Tissues
- Tissues are groups of similar cells that have a similar structure and function.
- There are four main types of tissues:
- Epithelial: Covers body surfaces and lines body cavities.
- Connective: Supports and connects other tissues.
- Muscular: Enables movement.
- Nervous: Transmits nerve impulses.
Organs and Organ Systems
- Organs are structures composed of different tissue types working together to perform specific roles.
- Organ systems are groups of organs that work together to carry out complex functions.
- Different organ systems, with their specific organs, work collectively to efficiently carry out various functions throughout the human body.
Organ Systems
- Various functions are described for each organ system, including circulatory, digestive, endocrine, integumentary, lymphatic, muscular, nervous, reproductive, respiratory, skeletal, urinary, and immune. These are examples, not an exhaustive list, although some of their specific functions are mentioned.
