Anatomy and Physiology …A to the P…

A to the P? What is a good definition for Anatomy? What is a good definition for Physiology?

Anatomy and Physiology What can you determine about this animal based on this bone?

A to the P? What’s that? What is a good definition for Anatomy? What is a good definition for Physiology?

Levels of Organization  Atomic: atoms and subatomic particles  Compounds: 4 classes of organic compounds  Cellular: basic living units  Tissue: groups of similar cells with one function  Organs: groups of tissues with one unifying function  Organ systems: groups of organs with one unifying function  What are the organ systems of the human body?

Homeostasis ATOMIC LEVEL COMPOUNDS CELLULAR TISSUES ORGANS ORGAN SYSTEMS Assignment: write a 2 paragraph essay title “Homeostasis” that is based off of the following list of words

Basic Characteristics of Life Growth Reproduction Movement Metabolism Responsiveness

Anatomy - Macroscopic Macro and Micro Anatomy Macroscopic Gross Anatomy: features seen with the naked eye Surface Anatomy: examines general form and markings Systemic anatomy: anatomy of organ systems

Anatomy – Microscopic Microscopic Anatomy Cytology: Studies… Histology: studies…

Physiology “Categories” Human Physiology: Cell Physiology: Special Physiology: Systemic Physiology: Pathological Physiology (pathology):

Systems Overview NOTEBOOK ASSIGNMENT Using chap 1, find the 11 human systems and briefly describe them. System NameFunctionMajor Structures skeletalMovement, support, protection Bones, ligaments

Homeostasis Definition: Maintaining a balanced, stable, relatively unchanging internal environment. Homeostatic regulation: The bodies response to preserve homeostasis

Homeostasis Regulation Receptor: receives a stimulus Control center: processes info from the receptor Effector: makes the changes

Types of Homeostatic Regulation 1. Negative Feedback loops: Maintain balance, or “neutral” - Thermostats - Insulin and blood Sugar 2. Positive Feedback loops: causes a stimulus to be reinforced and accentuated. - Blood clotting

Insulin Based Negative Feedback Loop

Clotting Factor based positive feedback loop
