Study Notes
Study of the Human Body
- The study of the human body is known as anatomy.
- An adult male body consists of approximately 55-60% water.
Physiology
- The main function of physiology is to understand the functions and processes of the human body.
Composition of the Human Body
- The human body does not contain the element of Argon.
Embryology
- Embryology focuses on the development of the human body from conception to birth.
Cell Biology
- The primary focus of cell biology is to understand the structure and function of cells.
- DNA is located in the nucleus of a cell.
- Epithelial cells regulate what can and cannot pass through them, protect internal structures, and function as sensory surfaces.
- The fundamental unit of life in the body is the cell.
- Epithelial cells line internal cavities, including blood vessels and glands.
Electrolytes and Body Water
- The main electrolytes in body water outside cells are sodium, potassium, and chloride.
- The main electrolytes in body water inside cells are potassium, magnesium, and phosphate.
Cell Function and Gene Expression
- DNA dictates cell function and gene expression.
Erythropoiesis
- Mature red blood cells lose their nucleus in the bone marrow.
Histology
- The study of tissues is called histology.
Non-Human Cells and Non-Cellular Material
- The weight of non-human cells or non-cellular material in an average human body is approximately 1-2 kg.
Physical Constants
- The fine-structure constant (α) characterizes the strength of the electromagnetic interaction.
- A physical constant is distinguished from a mathematical constant in that it has a unit and a numerical value.
- The speed of light (c) signifies a maximum speed for any object.
- The proton-to-electron mass ratio is a fundamental physical constant that characterizes the mass of a proton relative to an electron.
- The primary focus of the expression 'fundamental physical constant' is to identify a set of constants that define the universe.
- Empirical constants are different from fundamental physical constants in that they are derived from experiments, while fundamental physical constants are inherent to the universe.
- Physical constants in a physical theory are parameters that cannot be explained by the theory.
- The numerical values of dimensional physical constants depend on the unit system used.
- The speed of light (c) and the gravitational constant (G) are physical constants with known exact numerical values in the SI unit system.
- The Avogadro constant (NA) and the Boltzmann constant (kB) are examples of physical constants that have a dimension.
- Natural units are defined using dimensional universal physical constants.
- Physical constants must be measured experimentally because they are fundamental parameters that cannot be derived from theory.
- Maxwell's equations are crucial in understanding the speed of light.
- The speed of light is a fundamental constant in the theory of special relativity.
- The speed of light defines the international unit of length.
- Physical constants are considered as parameters that cannot be explained by a theory because they are fundamental and inherent to the universe.
