System Function Matching!

Integumentary System PROTECTS!

Skeletal System SUPPORT! BLOOD CELLS FORMED WITHIN BONES

Muscular System MOVEMENT! PRODUCES HEAT

Nervous System CONTROL SYSTEM!

Endocrine System SECRETES HORMONES THAT REGULATE GROWTH, REPRODUCTION, AND METABOLISM

Cardiovascular System TRANSPORTATION!

Lymphatic System DEFENSE!

Respiratory System GAS DELIVERY AND EXCHANGE (O2 AND CO2)

Digestive System PROCESSES FOOD ABSORBS NUTRIENTS

Urinary/Excretory System EXCRETES WASTES, WATER, AND SALTS

Reproductive System Male  PRODUCES SEX CELLS AND HORMONES Female 

What is the term for largest classification of anatomy structures? Gross

Gross Anatomy The anatomical position (see right) Directional and regional terms Anterior Posterior Superior Inferior Medial Lateral Proximal Distal Superficial Deep Cephalic Vertebral Thoracic Appendicular Brachial Lumbar

Anatomical Position Body erect, feet together, palms facing forward, thumbs away from body. Note: when talking about right/left, you are talking about the patients right or left side, not your own.

Divisions of the Body Axial: head, neck and trunk. Contains dorsal and ventral cavities. Appendicular: upper and lower limbs

Relative Positions Describes the location of one part of the body in relation to another.

Superior: above another part or closer to the head Inferior: below another body part or closer to the feet Anterior (ventral): towards the front of the body (breastbone anterior to spine) Posterior (dorsal): towards the back of the body (spine posterior to the breastbone) Medial: toward the middle of the body

Lateral: away from the middle, towards the outer side of the body Proximal: closer to the point of attachment to the trunk (elbow is proximal to the wrist) Distal: farther from the point of attachment to the trunk (knee is distal to the thigh) Superficial: toward or at the body surface Deep: away from the body surface, more internal

Body planes and sections - cut into sections along a flat surface called a plane (also called coronal) (also called XS – cross section)

Body planes Body is 3D Can be split into three planes Sagittal Coronal Transverse

Sagittal Plane Plane splitting the body into two parts (left and right) Sagittal section is a cut made longitudinally along the body If it splits into two equal parts = midsagittal

Coronal Plane Plane which splits body into anterior and posterior section Ie. Facelift

Transverse Plane Separates body along horizontal plane Also called a cross section Will divide an organism into superior and inferior parts

Body Cavities

Cavities Opening within body which protects internal organs, and allows transfer of materials/information 2 Divisions Dorsal Ventral http://en.wikipedia.org/wiki/File:Scheme_body_cavities-en.svg

Dorsal Cavities Made up of two smaller cavities 1) Cranial Cavity – holds and protects brain 2) Spinal Cavity – column which runs through vertebra and protects spinal chord

Ventral Cavities Thoracic Abdominopelvic

Ventral Cavities 1) Thoracic – chest area (holds heart, lungs, and diaphragm) 2) Abdominopelvic – lower torso (holds digestive and reproductive organs)

Collapsed Lung in Pleural Cavity Bovine Pleural Cavity Collapsed Lung in Pleural Cavity Pleural cavity is the space between the membranes covering the chest wall and lungs.
