Lecture: Chapter 01 Flashcards
To provide a comprehensive preparatory experience for the first exam.
ANATOMY
Anatomy studies the structure of body parts and their relationships to one another.
PHYSIOLOGY
Physiology concerns the function the body and its parts - how everything works.
GROSS ANATOMY
a.k.a. MACROSCOPIC anatomy: The study of body parts visible to the naked eye. Includes Regional, Systemic, & Surface anatomy.
REGIONAL ANATOMY
(subset of gross anatomy) the study of structures in a particular region (i.e. chest or arm)
SYSTEMIC ANATOMY
(subset of gross anatomy) the study of body systems (i.e. circulatory or nervous)
MICROSCOPIC ANATOMY
The study of body parts NOT visible to the naked eye. Includes Cytology and Histology.
CYTOLOGY
The study of TISSUES.
HISTOLOGY
The study of TISSUES.
EMBRYOLOGY
(subset of developmental anatomy) covers the developmental changes that occur before birth.
STRUCTURAL HIERARCHY
Chemical-> Cell-> Tissue-> Organ-> Organ System-> Organism
BODY SYSTEMS
(11) Integumentary; Skeletal; Muscular; Nervous; Endocrine; Cardiovascular; Lymphatic/Immune; Respiratory; Digestive; Urinary; Reproductive
INTEGUMENTARY SYSTEM
Skin, Hair, Nails: forms the external body covering, and protects deeper tissues from injury. Synthesizes Vit. D and houses cutaneous (pain, pressure etc) receptors and sweat and oil glands.
SKELETAL SYSTEM
Bones, Joints: Protects and supports organs, and provides framework for muscles to move. Bone stores minerals, and bone marrow creates blood cells.
MUSCULAR SYSTEM
Skeletal Muscles: Allows locomotion, facial expression, and manipulation of environment.
NERVOUS SYSTEM
Brain, Spinal Cord, Nerves: Responds to internal and external changes by activating appropriate muscles and glands. The control system of the body.
ENDOCRINE SYSTEM
Pineal Gland, Thyroid Gland, Pancreas: Secretes HORMONES that regulate processes such as growth, reproduction, and metabolism by body cells.
CARDIOVASCULAR SYSTEM
Heart, Arteries, Veins: Heart pumps blood through vessels to transport oxygen, carbon dioxide, nutrients, and wast.
LYMPHATIC/IMMUNE SYSTEM
Sleen, Lymph Nodes, Thymus: Returns leaked fluid to blood vessels. Houses white blood cells and attacks foreign substances.
RESPIRATORY SYSTEM
Lungs, Airways: Keeps blood supplied with oxygen and removes carbon dioxide. Gaseous exchange occurs through walls of alveolar sacs.
DIGESTIVE SYSTEM
Oral Cavity, Esophagus, Stomach, Liver, Intestines: Breaks down food into absorbable nutrients. Indigestible stuff is excreted as feces.
URINARY SYSTEM
Kidney, Ureter, Bladder, Urethra: Regulates water, electrolyte, and pH balance of blood. Eliminates nitrogenous waste.
REPRODUCTIVE SYSTEM
You got this one DOWN.
SURVIVAL NEEDS
Nutrients(proteins, carbs, vitamins, minerals); Oxygen(20% of the air we breathe); Water(60-80% of body weight); Normal Body Temp(98.6F/37C); Appropriate Atmospheric Pressure(air too thin at high alt. for adequate gas exchange)
HOMEOSTASIS
Ability to maintain a stable internal environment, a state of dynamic equilibrium. (Nervous & Endocrine systems bear major responsibility)
