Organization of the Human Body

Do Now There are 11 human body systems. Name as many as you can. As an added bonus, can you tell me what each system does? Winner gets a “Get out of Homework Free Pass”

The 11 Body Systems Digestive System Respiratory System Muscular System Circulatory System Nervous System Reproductive System Skeletal System Integumentary System Immune/Lymphatic System Excretory System Endocrine System

Homework Read Section 30.1 on P. 862 Define Epithelial tissue Connective tissue Nervous tissue Muscle tissue KNOW THE DIFFERENCE BETWEEN THE 4!

Human Body Systems Nervous System – Recognizes and coordinates the body’s response to changes inside and outside the body Integumentary System – Skin! Guards against infection and UV radiation. Regulates body temperature Immune/Lymphatic Systems – Protects body from disease

Human Body Systems Muscular System – Helps the skeletal system to produce voluntary movements. Helps circulate blood and move food through digestive system Circulatory system – Transports oxygen, nutrients and hormones to cells. Regulates body temperature. Skeletal System – Supports the body. Protects internal organs

Human Body Systems Respiratory System – Brings in oxygen needed for cellular respiration. Removes excess CO 2 Digestive System – Breaks down food, absorbs nutrients, eliminates waste Excretory System – Eliminates waste products from the body

Human Body Systems Endocrine System (hormones) – Controls growth, development and metabolism Reproductive System – Produces offspring. Females nurture and protect developing embryo

Organization of the Body Cells – Basic units of life, structure and function Tissues – Group of cells performing a specific function I.Epithelial Tissue II.Connective Tissue III.Nervous Tissue IV.Muscle Tissue Organs – Group of tissues that work to perform a single function Organ Systems – Group of organs that perform closely related functions EXAMPLE – Stomach and Large Intestines are apart of the Digestive System

Epithelial Tissue What does it do? Protects, absorbs and excretes materials Where can it be found? Skin, lining of digestive system, certain glands

Connective Tissue What does it do? Binding of epithelial tissue to structures, support and transport of substances Where can it be found? Under skin, surrounding organs, blood, bones

Nervous Tissue What does it do? Receives and transmits nerve impulses Where can it be found? Brain, spinal cord, and nerves

Muscle Tissue What does it do? Voluntary and involuntary movements Where can it be found? Skeletal muscles, muscles surrounding digestive tract, blood vessels and the heart
