13-15.-Heart-Blood -Blood vessel

Trivia!! If you were to lay out all of the arteries, capillaries and veins in one adult, end-to-end, they would stretch about 60,000 miles (100,000 kilometres). What's more, the capillaries, which are the smallest of the blood vessels, would make up about 80 percent of this length. By comparison, the circumference of the Earth is about 25,000 miles (40,000 km). That means a person's blood vessels could wrap around the planet approximately 2.5 times!

Capillaries are tiny, averaging about 8 microns (1/3000 inch) in diameter, or about a tenth of the diameter of a human hair. Red blood cells are about the same size as the capillaries through which they travel, so these cells must move in single-file lines.

Across the animal kingdom, heart rate is inversely related to body size: In general, the bigger the animal, the slower its resting heart rate.

In a particularly memorable scene in the 1984 film, "Indiana Jones and the Temple of Doom," a man rips out another man's still-beating heart. While easily removing a person's heart with your bare hand is the stuff of science fiction, the heart actually can still beat after being removed from the body.

Unlike most other cells in the body, red blood cells have no nuclei. Lacking this large internal structure, each red blood cell has more room to carry the oxygen the body needs. But without a nucleus, the cells cannot divide or synthesize new cellular components.

The oxygen-rich blood that flows through your arteries and capillaries is bright red. After giving up its oxygen to your bodily tissues, your blood becomes dark red as it races back to your heart through your veins.

Red blood cells may live for about 4 months circulating throughout the body, feeding the 60 trillion other body cells.

It takes about 20 seconds for a red blood cell to circle the whole body.

THE RESPIRATORY SYSTEMThe human respiratory system is a series of organs responsible for taking in oxygen and expelling carbon dioxide. The primary organs of the respiratory system are lungs, which carry out this exchangeof gases as we breathe.Red blood cells collect the oxygen from the lungs and carry it to the parts of the body where it is needed.Part I

Materials: A plastic bottle A bendable straw An elastic band Scissors 2 balloons Play dough/clay

Procedure:1. Remove the bottom of your bottle2. Tie a knot in one end of a balloon and snip of the fat end3. Stretch this end around the bottom of your plastic bottle4. Put a bendable straw in the neck of the other balloon and secure tightly with the elastic band but not so that you crush the straw. The air must flow through so test it with a little bow through the straw to see if the balloon inflates.5. Put the straw and the balloon into the neck of the bottle and secure with the play dough/ clay making a seal around the bottle make sure that again, you dont crush straw.Your lung is finish and now for the action.

Evaluation:1. In your own explanation, how does the diaphragm works?

Questions:1. The part of chemistry that studies amounts of substances that are involved inreactions.

Answer key: 1. Stoichiometry 2. Molar mass3. 2.2 moles Al4. Percentage composition5. Mass due to specific composition X 100 Total molar mass of composition

6. 88.89 %7. 62.54 %8. 41.9 %9. 72 %10. 0.8 %

Trivia!!! Avogadro's Constant defines a mole as having a value of 6.02214129(27) x 1023, as it refers to the number of particles of a substance.

The basic correlation is that a mole is the amount of any known or unknown substance that has as many elementary entities as there are atoms in twelve grams of pure carbon-12.

That means that one mole of pure C-12 must have a mass of twelve grams in order for the unit of measurement to line up.

The number of elementary entities in any substance is known as its chemical amount, which makes the mole an easy to use unit of measurement for chemical amounts.

In chemistry, a mole is a more convenient standard unit than attempting to measure in mass or volume, especially in chemical equations.

The representation in measurement is further simplified by the concept of the molecular mass, which states that the mass of one mole of a substance (measured in grams) is equal to the molecular mass.

Therefore, one mole of a substance is equal to the molecular mass of the same substance.

The development of the mole as the standard unit of measurement for calculating the elementary entities contained within a substance has a history that dates back to the first table of relative atomic mass, crafted by John Dalton in 1805.

Later, Jons Jacob Berzelius was instrumental in redefining relative atomic mass with a greater degree of accuracy.

For some time, hydrogen and then oxygen-16 became the standard for comparison in measuring units, following the use of mass spectrometry.

STOICHIOMETRY

It's a big word that describes a simple idea. Stoichiometry is the part of chemistry that studies amounts of substances that are involved inreactions. You might be looking at the amounts of substances before the reaction. You might be looking at the amount of material that is produced by the reaction. Stoichiometry is all about the numbers.

Allreactionsare dependent on how much stuff you have. Stoichiometry helps you figure out how much of acompoundyou will need, or maybe how much you started with. We want to take the time to explain that reactions depend on the compounds involved and how much of each compound is needed.
