1. INTRODUCTION INTO ANATOMY & HOMEOSTASIS THE BOYZ

2. ANATOMY -Anatomy is the study of the structure of organisms and their body parts. -Anatomy shows us how our body systems work together with each other in order for us to function and live day to day in the dangerous world we live in today. -During anatomy, the body systems, terms, organs, and body parts are covered. -Anatomy is used in medical fields as well as other biology fields. -Anatomy is organized in this order atom>cell>tissue>organ>organ system>organism

3. INTERNAL CHARACTERISTICS Body Temperature- production & distribution of blood flow Body Fluid Composition- nutrient absorption storage and release (O2 & CO2) – absorption of O2, elimination of CO2 Body Fluid- elimination of conservation of water from blood. Absorption of water loss of water in feces Water Product Concentration- eliminate of waste products Transport of waste products to sites of excretion Blood Pressure- pressure generated by the heart moves blood through blood vessels

4. ORGAN SYSTEMS Integumentary- skin, hair, and nails Skeletal - support and protection Muscular – movement of the muscles Nervous – control system Endocrine- transporting with the body Circulatory- transport and delivery Lymphatic- body’s defense system Respiratory system- gas exchange Digestive- breaking down food and waste output Reproductive – production of offspring

5. SYSTEMS Digestive: Stomach, tongue, esophagus, gallbladder, intestines (Digesting food) Skeletal : bones (Protection) Respiratory: Sinuses, bronchi, alveoli (Breathing) Reproductive: Penis, vagina, ovaries, testis. (Hormonal Changes/Reproduce) Urinary: urethra, kidneys (Excretion)

6. HOMEOSTASIS This maintains a steady internal habitat in order for the body to function. -This relies on --chemical composition -- temperature -- pressure and volume The body works as team to maintain a homeostasis If homeostasis is not meant it could lead to death or illness.

7. FEEDBACK LOOPS In feedback loops, negative and positive feedback loops determine if the reactions are sped up or slowed down to stay at a constant. With these feedback loops we are able to tell our bodies as said above, to speed up certain situations such as blood clotting a wound, or slow down something such as internal temperature.

8. QUESTIONS What organs are in the digestive system? What does the reproductive system do? What are the levels of organization? What is the function of the respiratory system? What is anatomy in general?
