Anatomy

Is the study of the structure of living organisms, including their internal and external parts

Anatomy

It’s a bunch of biology and medicine that explores how the body is made up and how it’s various components are organized

Gross anatomy (visible)

Histology (microscopic)

Anatomy and compasses both ____ and

____ levels of organization

Physiology

A branch of biology that deals with the functions and activities of life are a living mother, such as organs, tissues, or cells end of the physical and chemical phenomena involved

Structure

Function

Anatomy studies the ___ of the body, while Physiology studies its ____

how

why

There are two sides of the same coin with anatomy providing the ___ and physiology the ____ Of the body’s workings

Atom, molecule, macromolecule, organelle, cell, tissue, organ, organ system, organism

Organization levels of the body/ Structural Organization of Living Organisms

Integumentary system

Skeletal system

Muscular system

Nervous system

Endocrine system

Cardiovascular system

Lymphatic system

Respiratory system

Digestive system

Urinary system

Reproductive system

Organ systems in the human body

Dorsal (posterior) cavity

Ventral (anterior) cavity

Two main body cavities

Cranial cavity

Contains the brain

Vertebral/Spinal cavity

Contains the spinal cord

Thoracic cavity

Contains the chest

Pleural Cavity

Contains the lungs

Pericardial cavity

Contains the heart

Abdominal cavity

Contains the stomach, intestines, liver, spleen, pancreas, kidneys, and adrenal glands

Pelvic cavity

Contains urinary bladder, reproductive organs and Rectum

Homeostasis

Is a Physiological process that keeps the internal environment of a living organism, stable, and balance

Stimulus

Produces change in variable

Effector

Feeds back to influence magnitude of stimulus and returns variable to homeostasis

Receptor

Detect changes

Homeostasis

Is a property of a human biological system where the self regulating process to maintain the balance for the survival regulation takes place and defined internal environment

Stimulus

Receptor

Control center

Effector

Feedback

5 key components of Homeostasis

Effector

Receptor

Control center

Regulation of homeostasis depends on three mechanisms

Vasodilation

If the temperature is too hot, the blood vessels dilate

Vasoconstriction

If the external temperature is too cold, the blood vessels, constrict and enable body To retain heat

Osteology

Detailed knowledge of the skeletal system is particularly important as its primary focus of many radiographic examination

Surface landmarks

Radiographers use external landmarks to locate and position body parts, accurately, ensuring that the desired anatomical structures are included in the radiographic image

Pathology

Understanding how diseases alter normal anatomy and physiology is essential for recognizing abnormalities and radiographic images and making accurate diagnosis

Radiographic positioning

Knowledge of both anatomy and Physiology is critical for proper patient positioning during radiographic procedures, ensuring optimal, image, quality, and diagnostic information

Image interpretation

Understanding, normal anatomy and physiology allows Radiographers to identify deviations from the norm, helping them to interpret geographic images and recognize potential pathologies
