Driving Question The dawn of the 21st Century helped us because Of

the new advanced technologies and also made scientists start looking for cures to the most common known diseases, It also helped us advance on the ways and how we now think about our world and how to help our environment today from back on the late 1900s, one of the ways it hindered is that With pollution people are getting sicker and our atmosphere is getting weaker And If our atmosphere gets weaker we will not get clean enough air And then We will not be able to sustain life and all the plants / trees will not be able to get clean oxygen.

What are the parts of the digestive system?1. Mouth – Food broken down by chewing and chemical action of saliva.2. Salivary Glands - Saliva contains enzymes that break down carbohydrates

into smaller molecules.3. Esophagus - The esophagus is a long tube that uses rhythmic, wave-like

muscle movements (called peristalsis) to force food from the throat into the stomach.

4. Stomach - Food in the stomach is partly digested and mixed with stomach acids

5. Liver - Makes bile which breaks down fats and some blood proteins. Helps the small intestine in digestion.

6. Gall Bladder - It stores and releases bile into the small intestine.7. Pancreas - Enzymes from the pancreas help in the digestion of

carbohydrates, fats and proteins in the small intestine.8. Small Intestine – bile, pancreatic enzymes, and other digestive enzymes

produced by the inner wall of the small intestine help in the breakdown of food. Most food is absorbed here.

9. Large Intestine - The large intestine is responsible for absorption of water and excretion of solid waste material.

10. Rectum – Feces are stored here.11. Anus – Where feces exits the body.

Pick one of the following systems to talk about. We chose the Excretory system – The Main part of the excretory system is to remove wastes from the

Body.

Parts in the excretory system

1. Kidney – Cleans the blood of waste products. Waste is passed out your body in urine.

2. Ureter – Takes urine from the kidney to the bladder.

3. Bladder – Stores urine until it is passed out the body in urine.

4. Urethra – Urine passes from the bladder to the urethra on the way out of the body.

Explain how multi cellular organisms are - cells make up tissues Tissues make up organs Organs make up our system Systems make up an organism

Advantages of being a multicellular organism. - One example Is Multicellular organisms Have 7

Specialized cells making them able to do a lot more than unicellular organisms They also Have way more cells then a unicellular organism.

What are the main components of blood and their function?

Red blood cells: Are Responsible For moving the oxygen's to the body.

White blood cells: kill all bacteria and germs and Helps prevent diseases.

Platelets: blood clotting cells make the scab when ever you get a cut

Plasma: brings nourishment to cells and removes waste from the other cells

Choose 3 systems of the body and then name and describe at least two common disorders of that system. Be sure to explain how doctors think the disorders are caused

Respiratory system.- lung cancers: Lung Cancers are mainly caused by smoking. Emphysema: Can occur when repeated breathing in of fumes and

other things that irritate and damage the lungs and airways.

Digestive system.- Cancers: Cancers are started in your tissues in your stomach and

cancers can form everywhere. Ulcers: stress, spicy foods, and alcohol caused most ulcers.

Circulatory System. – High Blood Pressure: High blood pressure is caused By Having a

High intake of salts and Sugars. Strokes – Strokes can occur when your brain doesn't get enough

oxygen,

With those same three body systems from above, now explain what we can do to keep those systems healthy Respiratory - surround yourself in clean healthy

air, don't smoke or try not to be around smoking.

Digestive - eating healthy will help stop cancers and other diseases, also eating a lot of proteins help muscle growth. fat is an also an essential in keeping our organs cushioned and give us energy.

Circulatory – To Stop a Stroke or High blood pressure you Cant Eat much foods containing

high salts And other sugars.

How is blood the transportation System for the body. - Blood moves the nutrients around the

body. Blood also helps organize the cells in your body

Blood - Blood is fluid that all organisms have and that delivers necessary substances such as nutrients and oxygen to the cells and transports waste products away from those same cells.

Respond to the Quote. Quote: “Almost 60% of all Canadian adults and 26% of our

children and adolescents are overweight or obese.” -Canadian Heart and Stroke Foundation

Our response is most people are obese because of fast foods, also People do not watch how much they eat, people don’t really exercise and when People do they usually eat As soon as they start to exercise, and when they take a break they usually don’t get back to exercising. Also people eat fast food And that’s how the number of obesity go up And It keeps to get Higher and Higher throughout the year.

Thanks for Watching!
