Acknowledgement We are highly thankful to science teacher Mrs. Jayshree Purohit who gave chance to present project before class . This project could never get shape without the blessing of our parents whose efforts can not be forgotten. We are presenting before you Presentation on

Blood & circulation : 

Blood & circulation

Slide 5: 

Our body resembles a large roadmap, There are routes or “arteries” that take you downtown to the “heart” of the city. Circulation

Slide 6: 

TYPES OF CIRCULATION Brain Circulation Muscles. Heart (Coronary) Circulation.  Skin. Kidneys.

3 Major Parts of the Circulatory System : 

3 Major Parts of the Circulatory System Blood Vessels - Routes blood travels Heart – Pumps or pushes blood through body Blood – Carries important “ *stuff ” through body * Stuff – includes oxygen, food, & waste

Blood Vessels : One Way Streets : 

Blood Vessels : One Way Streets Blood Vessels resemble very long and skinny tunnels that are all through our body.

Slide 10: 

4 Chambers ( or Compartments ) 2 Upper Chambers : Left Atrium Right Atrium 2 Lower Chambers : Left Ventricle Right Ventricle The Heart

Lub : 

Lub If you listen to our heartbeat, it makes a lub dub sound. The lub is when blood is pushed out of the heart into the body and the dub is the reloading of the heart with more blood ready to push it out to the body Dub

Slide 13: 

Heart Rate can be determined using a Stethoscope

Heart Facts : 

Heart Facts Hold out our hand and make a fist. If you're a kid, our heart is about the same size as our fist, and if you're an adult, it's about the same size as two fists. Our heart beats about 100,000 times in one day and about 35 million times in a year. During an average lifetime, the human heart will beat more than 2.5 billion times. Give a tennis ball a good, hard squeeze. You're using about the same amount of force our heart uses to pump blood out to the body. Even at rest, the muscles of the heart work hard--twice as hard as the leg muscles of a person sprinting.

Blood Flow through the Human Body : 

Blood Flow through the Human Body Blood with little oxygen is pumped from the Right Atrium through a valve to the Right Ventricle and through another valve into the Pulmonary Vein. The Pulmonary Vein sends it to the Lungs to pick up Oxygen. It’s sent from the Lungs through Pulmonary Arteries to the Left Atrium through a valve to the Left Ventricle. The Left Ventricle sends it through a valve to the Aorta. The Aorta is a series of branches that sends oxygenated blood throughout the body.

Our Blood is made up of : 

Our Blood is made up of Plasma Liquid part of blood Red Blood Cells - They carry oxygen to all parts of the body. It contains Haemoglobin

Haemoglobin : 

Haemoglobin 1. Gives red blood cells their colour 2. Can carry up to 4 molecules of O2 3. Associates and dissociates with O2 4. Contains iron

Slide 18: 

White Blood Cells Fight and kill germs that may enter our bloodstream

Slide 19: 

Platelets Form “scabs” when you cut ourself Helps stop the bleeding

Blood Types : 

Blood Types 4 main Blood Types: Type A, Type B, Type AB, and Type O
