Transcript of Circulatory System

Every day we wake up, eat, play, have fun but what makes sure we do these things? What keeps us going throughout the day but one day it eventually fails?I hope you guys know what I'm talking about .... it has something to do with blood .... yes, our heart! Even if its only the size of our fist, its the most important organ in our body. It pumps blood throughout our body with the help of veins. Thats what the circulatory system is all about! So sit back, relax, and enjoy our presentation!
Circu - what?
The Circulatory System

-allows us to breathe
-transports blood and oxygen from the lungs around the body
-protects the body from infections and blood lose
-helps the body maintain a constant body temperture
-helps maintain fluid balance within the body

-if it fails, death can occur instantly
-flow of blood is necessary to live
- it fights away viruses
- it keeps the body temperature in place
- blood can't be transported throughtout your body without the circulatory system


Importance
1. Heart

2.Blood

3.Blood vessels

4.Lungs
Major Organs
Well folks, there you have it! The Circulatory System is very important for us and our body. We hope you have learned one main thing from our presentation, without the circulatory system we would not be alive!! Thank you for giving us your time and attention.
ohhh ... cir-cu-la-to-ry
Relationship of the tissues and organs
Respiratory System -
lungs
Urinary System -
kidneys/bladder
Nervous System -
heart/lungs
Endocrine System
- major glands
Dependent on other systems
Arteriosclerosis-
artery walls thicken because of too much calcium or cholesterol

Hypertension-
also known as high blood pressure and can lead to heart attacks or strockes
Aortic Aneurysm-
the aorta gets damaged and eventually tears because of obesity, high blood pessure, or internal bleeding

Rheumatic Fever-a
ttack on valves that control blood flow throughout the heart
Congenital Heart-
incomplete development of the heart or blood vessels

Diseases/Disorders
By: Anosha, Kamaljit & Fatima
Heart
The job of the heart is to pump blood throughout the body. We need oxygen to give our cells energy. The oxygen we breathe in goes to our lungs. If the heart doesn't work then we die.
Blood
The job of the blood is to move nutrients, oxygen, and waste products through the body. Blood also carries cells which have their own functions.
*Red blood cells - carry oxygen
*White blood cells - germ fighters
Blood Vessels
Blood vessels come in different sizes. Some are large like a highway and some are small like streets.

Types of Blood Vessels:
1.
Arteries
-carry blood away from heart carrying oxygen.
2.
Capillaries
-exchange nutrients and oxygen with blood cells.
3.
Veins
-carry blood to heart carrying wastes.

The lungs are pairs of elastic, spongy organs used for breathing. In humans the lungs take up alot of the chest cavity. They are located just behind, and to either side of the heart.
Major Tissues
-blood gets pumped from the heart through blood vessels and into the lungs
-connective tissue supports the other tissues


Lungs
Function
Fun Facts
The bigger u are the slower the Heart beat
FUN FACTS
THE HEART DOES NOT NEED THE BODY THE BODY NEEDS THE HEART
WHO WANTS CANDY
1.
Connective tissue
- protects, supports other tissues together. connective tissue cells provide flexibility. some examples are bones and blood
2.
Adipose tissue
-stores energy, forms a protection around organs such as kidney, reduces heat loos, and its formed by groups of fat cells.
3.
Epithelial tissue
-covers the whole surface of the body. IT is made of cells closely packed and ranged in one or more layers
4.
muscle tissue
-is made of muscle cells use energy to contract and creat a pulling force.
5.
Nervous tissue
-is responsible for putting signals to and from different parts of the organsim.
