Warm Up

1. What do you want to accomplish in this class before the end of the school year?

2. What have we learned about the human body so far in this class?

Agenda• Objectives: SWBAT create a flowchart of the

levels of organization within an organism and be able to provide examples based on a particular system of the human body.

• Reminders: Progress Reports---Today at lunch and after school is your last chance to improve your progress report grades

• Start unit on the Human Body!

• Notes on Levels of Organization and Worksheets

• Exit Ticket

Characteristics of Life

Living things are organized at different levels.

Levels of Organization:

Cell(Smallest) Tissue Organ Organ System Organism(Biggest)

Cells• The most basic

unit of life.

• If we wanted to dig deeper, we would say that cells are built out of Organelles.

• Examples:

Tissues• Tissues are groups

of cells that are linked together.

• Tissues link cells, allowing the cells to carry out a specific function.

• Examples:

Organs• An Organ is a

collection of tissues in an organism.

• Organs carry out specific tasks in an organisms body.

• Examples: Can you name any of the organs in the picture?

Organ Systems• Organ systems are

groups of organs, linked together, all performing a single job together.

• Examples:

Organism: So many varieties!

Giant Squid Praying Mantis

MAJOR BODY SYSTEMS

• Nervous• Skeletal• Muscular• Integumentary (skin)• Digestive• Respiratory• Circulatory• Endocrine• Reproductive

Draw Chart

Nervous System

a. Function: receives and relays info about body activities

- Two Parts- Central Nervous System: Processes information

from the senses- Peripheral Nervous System: Controls voluntary

and involuntary actions by connecting the CNS with the organs and muscles.

b. Key Structures: Made up of nerve cells (neurons), brain, spinal cord

Nervous System d. The CNS contains the brain, brain stem and spinal cord. It processes information received from the body’s senses

e. The PNS connects the CNS with organs and muscles

f. There are two parts of the PNS:- Somatic nervous system

which controls voluntary actions

- Autonomic nervous system which controls involuntary actions

Alzheimer Diseasea. Cause: Unknownb. Cure: none c. 5.3 million Americans are

living with Alzheimer’s disease.

d. Alzheimer's destroys brain cells and causes problems with memory, thinking and behavior

e. Alzheimer’s gets worse over time, and it is fatal.

Skeletal Systema. Key Structures: Contains

bones and tissues- Axial Skeleton = skull,

cerebral column, sternum, ribs

- Appendicular skeleton = upper and lower limbs

b. Function:- Offers support, protection and

flexibility to organisms

- Forms blood cells

- Stores calcium

Osteoporosisa. Osteoporosis is a

disease in which bones become fragile and more likely to break.

b. Causes: not enough calcium and vitamin D, low weight, heredity

c. Women are 4 times more likely to get it

d. Treatment: vitamins, weight-bearing exercise

Muscular Systema. Function: allows substances to

move through the body and the body, itself, to move.

b. Key structures: There are 3 types of muscles:- Cardiac: found only in the heart- Skeletal: connects to bones by

tendons; involved with voluntary movement

- Smooth: connected to organs and is involved with involuntary movement

Muscular Systemc. There are two types

of filaments in muscles made up of certain proteins: Myosin and Actin

d. When a muscle contracts, the thin filament (actin) slides over the thick filament (myosin)

Muscular Dystrophya. Muscular dystrophy

(MD) is a genetic disorder that weakens the muscles that help the body move.

b. Cause: mutation in the genes

c. Affects male children and teens more frequently

d. No cure!

Integumentary System

a. Key Structures:- Skin, hair, nails, oil

glands, sweat glands, proteins

b. Largest Organ in the body

c. Function: Covers all the organ systems for protection

Impetigo a. Contagious skin infection that usually produces blisters or sores on the face, neck, hands

b. Cause: bacteriac. One of the most

common skin infections among kids.

d. Treatment: antibiotics (ointment or pill)

Digestive Systema. Key Structures: mouth,

esophagus, liver, gallbladder, large intestine, small intestine, rectum/anus, stomach

b. Function: - breaks down food into energy that

cells can use.- Absorb nutrients and transport them

to cells.- Eliminate waste as liquid and solid

through the Excretory System

Diarrhea and other diseasesa. frequent loose or liquid bowel

movements

b. Causes: viruses, parasites, bacteria in food or drinking water

c. Common death in developing countries; 2nd leading cause of infant deaths worldwide

d. Can lead to dehydration, which can lead to death

e. Cholera, a rapidly fatal disease, involves both diarrhea and dehydration

ReflectionDirections: Respond to the following questions in complete sentences in your notebooks.

•Which system of the body was the most interesting to you?

•What was something new you learned about the system?

Reading Guides

• By the end of this week, you should pick a system of the body for a mini project that you will complete

• In order to help you choose, you will complete at least 4 of these short Reading Guides by Monday.

• You choose which ones you want to do.• I will have more options available tomorrow.

Warm Up1. What does the nervous system do for the

body?

2. What is a disease that affects the skeletal system?

3. What is another disease/health issue that you think may affect the nervous, skeletal, muscular or integumentary systems?

Agenda• Objective: SWBAT complete a chart on

systems of the body as well as write a reflection on one of the systems

• Today– Complete overview of systems of the body– Opportunity for Community Service– Go over Mini Project– Individual Readings

Respiratory Systema. Key structures: nose, pharynx, larynx, trachea,

bronchi, bronchioles, lungs

b. Function: Supplies oxygen to the blood and removes carbon dioxide from the tissues.

Respiratory System

c. Breathing involves the diaphragm and muscles of the rib cage.

d. Air flows from areas of high pressure to low pressure.

Air inhaled.

Muscles contract andrib cage expands.

Diaphragm flattensand moves downward.

Air exhaled.

Muscles andrib cage relax.

Diaphragm relaxesand rises.

Cystic Fibrosisa. Cause: mutation in

the gene

b. Chronic disease that involves build-up of mucus in the lungs and digestive problems

c. Treatment: use of devices that help clear out the mucus; must use throughout lifetime

Circulatory System

a. Function: The circulatory system transports blood and other materials. – brings supplies to cells – carries away wastes – separates oxygen-poor and

oxygen-rich blood

b. Key structures: Heart, blood vessels (arteries, veins, and capillaries), blood

Circulatory System

c. Blood flows through the heart in a specific pathway- oxygen-poor blood enters right

atrium, then right ventricle– right ventricle pumps blood to

lungs– oxygen-rich blood from lungs

enters left atrium, then left ventricle – left ventricle pumps blood to body

Coronary Heart Disease

a. #1 killer in the United States

b. Cause: build up of plaque in the coronary arteries

c. The coronary artery supplies your heart with oxygen-rich blood

d. Can lead to a heart attacke. Prevention: eat well,

exercise, don’t smoke, monitor your cholesterol and blood pressure

Endocrine System

a. Function: Controls growth, development, metabolism and reproduction by secreting hormones from glands.

b. Key Structures: Glands like the Hypothalamus, pituitary, thyroid, adrenals, pancreas, ovaries, testes

Diabetes

a. Cause: pancreas does not produce enough of the hormone insulin to break down sugar in the body

b. Type I and Type IIc. Type II is becoming more

prevalent as the average weight of Americans increases

d. Treatment: Insulin injections, restricting sugar in the diet

Female Reproductive System

a. Function: produces sex cells (eggs); nurtures and protects a developing embryo

b. Key Structures: ovaries, fallopian tubes, uterus, vagina

Male Reproductive System

a. Function: produces sex cells (sperm)

b. Key Structures: testes, epididymis, vas deferens, urethra, penis

STDs

a. No cure: AIDS, genital herpesb. Curable: gonorrhea, chlamydiac. Cause: unprotected sexd. Treatment: depends on the specific type of STD

– Genital warts: freezing– Antibiotics
