Circulatory System
What is the main function of the Circulatory system
The circulatory system delivers oxygen and nutrients to cells and takes away wastes. The heart pumps oxygenated and deoxygenated blood on different sides. The types of blood vessels include arteries, capillaries and veins.
What are the inner planet? Which are the inner planets
The inner planets are the ones that are inside the asteroid belt and are smaller. Mercury, Venus, Earth, Mars
What is and insulator?
Where heat can't pass or pass very slowly
What is a electric circuit?
Electric circuit, path for transmitting electric current. An electric circuit includes a device that gives energy to the charged particles constituting the current, such as a battery or a generator; devices that use current, such as lamps, electric motors, or computers; and the connecting wires or transmission lines.
What are the parts of the Circulatory system?
Heart, Veins and Arteries
What are the outer planets? Which are the outer planets?
The planets that are out from the asteroid belt. Jupiter, Saturn, Uranus, Neptun
What is a conductor?
A thing in which heat can travel easily. Usually all the things made by iron or metal are good conductors.
How does it work
Correct
What does blood carry?
Oxygen and nutrients
What is the asteroid belt?
Is a divicion between inner and outter planets that is made from asteroids from Jupiter and Mars
What is radiation
Thermal radiation is radiation that things make because they are warm. It may be felt as heat or seen as light. It is a form of heat transfer that is moved from one place to another by electromagnetic radiation waves or rays. It does not require a form of matter to be transferred.
How many parts are there in the heart?
4 parts
What are Comets, Asteroids, Meteors, Meteoroids, Metorites.
Comets: Are made or dust rock and ice, and when it passes around or near the sun the ice melt, letting see a "estela" also lnown as coma.
Asteroids: They are made of rock, dust and metal and can be found in the asteroid belt. If they hit the Earth they can destoy the life that is in there
Meteoroids: Are tiny rock the size of a pebble that may not cause any damage.
Meteors: Are meteoroids that hit Earth atmosphere, we know them as "estrellas fugaces"
Meteorites: Are Meteoroids that enter to Earth and hits its ground. They can't be detected.
What is conduction?
Conduction is the transfer of thermal energy through direct contact. It is need a conductor to pass heat
What is the main difference between arteries and veins?
Arteries pass blood from the heart to the body and veins passes all the blood from the body to the heart

Very good
What is convection?
Convection occurs when heat is transferred through a gas or liquid as the hotter material moves to a cooler area.
