Example of All Tissues in Use
You accidentally place your hand on the hot eye of the stove top: Nerve Tissue: sends message to brain
that hand must be quickly removed Muscle Tissue: contracts to make hand
move away from stove Soft Connective Tissue: acts as
padding and prevents deeper damage Epithelial Tissue: damaged skin cells
by extreme heat

Muscular System
How do our muscles move??? 1.) Muscles are connected to bones by
tendons 2.) Convert chemical energy into tension 3.) Produce movement simply by
shortening (contraction) and then lengthening (relaxation)
4.) Muscles pull, but they cannot push!

Circulatory System
A.K.A: Cardiovascular System
Consists of: Heart and blood
vessels (Includes arteries
and veins) A pumping heart
forces blood to move in a circle throughout the system

Circulatory System
Blood: About 55% plasma
▪ (fluid containing water, proteins, sugar, hormones, etc.)
Carries oxygen and nutrients to entire body
Carries waste products away from cells
Helps produce cells to fight infection
Has clotting agents

Circulatory System
Our bodies actually have 2 Circulatory Systems: Systemic
▪ Carries oxygenated blood from heart to the rest of the body
▪ Returns deoxygenated blood back to heart Pulmonary
▪ Carries deoxygenated blood from heart to the lungs
▪ Returns oxygen-rich blood to the heart

Respiratory System
Primary function = supply blood with oxygen that will be delivered to all parts of body
Consists of: Nose and mouth Trachea/Throat Bronchi Alveoli Lungs

Lymphatic System
Filters lymph Lymph = white watery fluid that is
removed from blood during “cleaning process”
Collects and transfers fluids and plasma back into bloodstream
Assists with fighting infection

Immune System
Works with Lymphatic System
Our body’s defense system against disease and infection

Immune System
3 types of responses to danger (in the order they occur): Anatomic response
▪ Physically prevents substances from entering body▪ Ex: skin, stomach acid, membrane around organs, etc.
Inflammatory system▪ Pushes the invaders out of your body
▪ Ex: sneeze, cough, runny nose, fever, swelling
Immune response▪ White blood cells fight infection
▪ Works with Lymphatic System to filter out bacteria/infection

Immune System
Leukocytes (White blood cells) = our soldiers that fight the “bad guys”
White blood cells made by bone marrow

Immune System: Activity
1 volunteer will fight off invading bacteria
Then 5/more volunteers will join powers to fight off that same bacteria
The system is strong: white blood cells, anatomic response, inflammatory response, etc.

Digestive System
Digests food (physically and chemically)
Transports food Absorbs nutrients
and converts to energy
Eliminates waste
![Page 69: Miss Van Heuven. There are many different types of cells in the human body. None of these cells would function well on their own, they are part of the](https://reader035.vdocuments.mx/reader035/viewer/2022081519/56649db05503460f94a9e308/html5/thumbnails/69.jpg)
Digestive System
Food’s path: Saliva and teeth
slightly break down food
Esophagus = stretchy 10 inch pipe connecting back of throat to stomach
Epiglottis = flap that covers your windpipe
Stomach = shaped like letter “J” stores and breaks food down into liquid
![Page 70: Miss Van Heuven. There are many different types of cells in the human body. None of these cells would function well on their own, they are part of the](https://reader035.vdocuments.mx/reader035/viewer/2022081519/56649db05503460f94a9e308/html5/thumbnails/70.jpg)
Digestive System
And the path continues: Small Intestine: NOT
SMALL! (Adult = 22 ft when stretched out)
Extracts good stuff from food with help from Liver, Pancreas, and Gall Bladder
Nutrients then go to Liver and are mixed into blood
Waste moves on to Large Intestine
![Page 71: Miss Van Heuven. There are many different types of cells in the human body. None of these cells would function well on their own, they are part of the](https://reader035.vdocuments.mx/reader035/viewer/2022081519/56649db05503460f94a9e308/html5/thumbnails/71.jpg)
Digestive System
And continues…. Large Intestine is fatter,
but not longer than the small intestine
Appendix = at the end, but no real function
Colon = last chance to absorb nutrients (including H20)
So material becomes hard… i.e: poop!
Exits via the Rectum and finally the Anus

Urinary System
Filters blood to maintain fluid and electrolyte balance in the body
Produces and eliminates urine

Urinary System
You drink…you pee… but it is more complex than that: **Kidneys: filter waste from blood and
produce urine Ureters = 2 thin tubes that take urine
from kidneys to Bladder Bladder = a sac that holds urine until it
is time to go Urethra = a tube that carries urine out
of the body

Reproductive System
Provides for reproductionDifferent for males and females

Reproductive System
Main male parts: Testes (where sperm are produced) and
Penis Vas deferens (tube) carries semen (fluid
containing sperm) into abdominal cavity and then out of the ejaculatory duct
Main female parts: Vagina, uterus (receptacle for semen),
and ovaries (produce the ova) Vagina is attached to uterus by cervix Uterus is attached to ovaries by fallopian
tubes

Reproductive System
Fertilization = 2 types of sex cells (gametes) meet in the female reproductive organ: Sperm (male) and
Egg/Ovum (female)
Sperm combines with egg cell
Characteristics passed onto offspring through genes
