Anatomy and Physiology SBIO-221B
Respiratory System
A system of organs, functioning in the process of gas exchange between the body and the environment, consisting especially of the nose, nasal passages, nasopharynx, larynx, trachea, bronchi, and lungs.
positive feedback
A type of regulation that responds to a change in conditions by initiating responses that will amplify the change. Takes organism away from a steady state.
What are the levels of structural organization
Atoms , Molecules, Organelle, Cells , TIssues, Organs , Organ systems
Digestive System
Breaks down food into absorbable units that enter the blood for distribution to body cells.
Contains blood vessels that transport oxygen , carbon dioxide, nutrients, wastes, ect
Cardiovascular System
Gkands secrete hormones that regulate processes such as growth, reproduction, and nutrient use by body cells.
ENDOCRINE SYSTEM
Urinary System
Eliminates nitrogenous wastes from the body. Regulates water, electrolyte and acid-base balance of the blood.
identify the organ system responsible for secreting hormones that regulate growth, development, and metabolism.
Endocrine System
What region of the heart studies tissues of the heart.
Histology
Input
Info sent alog afferent pathway to control center
Output
Info sent along efferent pathway to effector
Forms the external body covering, and protects deeper tissues from injury.
Integumentary System
What are the necessay life boundaries.
Maintaining Boundaries, Movement, Responsivness, Digestion, Metabolism, Excretion, Reproduction and Growth.
Allows manipulation of the enviroment, locomotion, nad facial expression, Maintains posture, and produces heat.
Muscular System
What are survival needs
Nutrients, oxygen, water, normal body temp. and atmospheric pressure
What topic would you be studying if you investigated urine production by the kidneys
Renal physiology
Protects and supports body organs, and provides a framework the muscles use to cause movement.
Skeletal System
Anatomy
Studies the structures of body parts and their relationships to one another.
negative feedback
a mechanism of response in which a stimulus initiates reactions that reduce the stimulus
Embryology
a subdivision of developmental anatomy, cocerns the changes during birth
Regional Anatomy
all the structures in a particular region of the body, such as abdomen or leg, are examined at the same time.
Systemic Anatomy
body structure is studied system by system
Physiology
concerns the functions of body parts- what they do and how they do it
Microscopic anatomy
deals with structures too small to be seen with the naked eye
Receptor
detects change
What conditions or levels of variables have to be regulated in order to keep a cell "happy" within the body's internal environment? a) Temp b) Certain ions(Na+, K+. Ca2+. and H+) c) Nutrients d) Oxygen and carbon dioxide e) All the above
e) all the above
Variable
is the factor or event being regulated
What is the most common type of feedback
negative
What are the 2 types of Feedback Mechanisms
negative feedback and positive feedback
Control system of the body
nervous system
Stimulus
produces change in variable
Response
returns variable to homeostatic level
Reproductive System
system of organs involved in producing offspring
Homeostasis
the ability to maintain a stable internal environment
Lymphatic System
the network of vessels through which lymph drains from the tissues into the blood.
Surface Anatomy
the study of internal structures as they relate to the overlying skin surface
Developmental anatomy
traces structural changes that occur throughout the life span

your set point returns to a normal and you sweat.
