Study Notes

Principles of Anatomy and Physiology

This is a fifteenth edition textbook.
The authors are Gerard Tortora and Bryan Derrickson.
The first chapter is titled "An Introduction to the Human Body".
The text's purpose in this chapter is to: introduce anatomy and physiology; discuss the organization of the human body; and reveal shared properties of all living things as well as address the concept of homeostasis.

Anatomy and Physiology Defined

Anatomy is the study of structure.
Physiology is the study of function of body parts.

Branches of Anatomy

Embryology (embry- = embryo; -logy = study of): the first eight weeks of human development after fertilization.
Developmental biology: the entire process of human development from fertilization to death.
Cell biology: the structure and function of cells.
Histology (hist- = tissue): the microscopic structure of tissues.
Gross anatomy: structures that can be viewed without using a microscope.
Systemic anatomy: the structure of specific body systems such as the nervous or respiratory systems.
Regional anatomy: specific regions of the human body, such as the head or chest.
Surface anatomy: the surface markings of the body in order to understand internal anatomy by visualization and palpation or gentle touch.
Imaging anatomy: internal body structures are visualized using imaging techniques like x-rays, MRI, CT scans and other technologies that are used for clinical analysis and medical intervention.
Pathological anatomy: structural changes that are associated with disease (gross to microscopic).

Branches of Physiology

Molecular physiology: the function of individual molecules such as proteins and DNA.
Neurophysiology (neuro- = nerve): the functional properties of nerve cells or neurons.
Endocrinology (endo- = within; -crin = secretion): hormones, the chemical regulators in the blood and how they control body functions.
Cardiovascular physiology (cardi- = heart; vascular = blood vessels): the functions of the heart and blood vessels.
Immunology (immun- = not susceptible): the body's defenses against disease-causing agents.
Respiratory physiology (respira- = to breathe): the functions of the air passageways and lungs.
Renal physiology (ren- = kidney): the functions of the kidneys.
Exercise physiology: changes in cell and organ functions due to muscular activity.
Pathophysiology: functional changes associated with disease and aging.

Levels of Structural Organization and Body Systems

Chemical Level: Atoms combine to form molecules.
Cellular Level: Molecules combine to form cells.
Tissue Level: Similar types of cells combine to form tissues.
Organ Level: Different tissues combine to form organs.
System Level: Different organs that work together to perform specific functions form systems.
Organismal Level: All the parts of the body functioning together to maintain life form the human organism.

Systems of the Human Body

Integumentary
Skeletal
Muscular
Nervous
Endocrine
Cardiovascular
Lymphatic/immune
Respiratory
Digestive
Urinary
Reproductive

Clinical Connection

Noninvasive Diagnostic Techniques: Inspection, palpation, auscultation, percussion
Inspection: observing the body
Palpation: feeling the body
Auscultation: listening to the sounds inside the body
Percussion: tapping on the body to detect sounds

Characteristics of the Living Human Organism

Metabolism
Responsiveness
Movement
Growth
Differentiation
Reproduction

Homeostasis

Homeostasis is a state of equilibrium in the body's internal environment.
Structures at various levels contribute to maintain internal environment within normal limits.
Various organ systems work together to maintain homeostasis by exchanging substances.

Control of Homeostasis

Negative Feedback: reverses a change in a controlled condition.
Positive Feedback: strengthens a change in a controlled condition.

Homeostatic Imbalances

Disruptions of homeostasis result in disease or death.
Factors like genetics, air, food, and thoughts can affect health.
