You'll need 4 small plastic bottles for chambers
and two larger ones for the lungs,
clear tubing for blood vessels, a pump or two, since blood goes from the left ventricle to the aorta and from the right ventricle to the lungs at the same time, and modelling clay to leak proof the model. Remember to include the aorta, pulmonary veins, pulmonary areteries and vena cavas. Get the tubing from a hardware store and pump from a pet store (for a fish tank). You'll also need red food coloring and water for blood. You also need a box to put it in. Decorating the box is up to you.
To build a working model heart out of easy-to-find materials, you can use playdough or clay to sculpt the shape of the heart, bendy straws for blood vessels, and a balloon or rubber glove for the balloon or pump. Connect the straws to the balloon or glove to mimic blood flow. Add food coloring to represent blood and demonstrate circulation.
it tells him how efficiently your heart is working
The higher the temperature, the faster the heart rate of the Daphnia. The lower the temperature, slower the heart rate of the Daphnia.
Brain Stem
In a normally functioning heart, the SA (sinoatrial) node is the pacemaker of the heart, but if it is nonfunctional then the AV (atrioventricular) node would take over. If it isn't working either then the Bundle of His can trigger contractions, and if it isn't working the Perkinje fibers can trigger contractions. Each progressive one has a slower intrinsic heart rate.
An organ is a group of tissues working together to perform a particular function. Examples include the heart, lungs, and liver.
it increases (goes faster) because its working harder to build up ur heart
You will need a few plastic empty bottles or a ziploc pouch or bag that may be lying aroud the house, you will also need tubes or straws, you may need batteries as well since you want to build a working model of the heart, check out the nearest dollar store or try working with things you can easily find at home to save you time and money.
Your heart will be beating and you will be living. You cannot live if your heart is not working.
Yes, They are part of the Circulatory System, an organ system that distributes materials and nutrients around the body.
In your heart
the heart is made from many materials such as muscle.
A big heart
It is true because if your heart stops working, you can die.
If the apex of the heart is not working properly it is as a result of the congestive heart failure. This usually requires immediate medical attention and dietary changes.
Heart rate monitor
You will get a heart attack
well, I would use clay or something..... I NEED THE ANSWER TO THIS ALSO FOR A PROJECT!!!!!! but for a start, use clay, and I would put in plastic tubes with a red liquid.
