So What Happens to the Body When We Warm. Up? Task 2: Fill in the gaps with the words on the next page.
We warm up to...
1. Gradually increase the heart rate and hence the blood flow to the muscles, supplying them
which allows them to work more intensively and efficiently with more elasticity
with
2. Remove waste fluid and waste products from the
cardiovascular system, e. g. helps to avoid a bulld-up of lactic acid
by acceleration of the
3. Increase the depth and rate of
ensuing exercise
required to achieve the appropriate level for
4. Increase the supply of
to the joints. This lubrication increnses the range of
notion in the joints and helps to decrease wear and tear,
5. Increase the body temperature giving increased muscle efficiency and
6. Improve
and dilate lopen up the skin vessels in
order to allow heat loss and body temperature to be maintained at safe levels.

Option 1.

Explanation:

When we warm up, our heart rate increases and we require much more energy to continue. Hence, our body absorbs much more oxygen from the surroundings, digest food and etc.

Sorry if the explanation might sound wrong, I learned this during science 2 years ago so I forgot.

vanderwaal's forces of attraction are the electrostatic intermolecular forces that exist in a molecule due to the temporary or permanent dipoles that are developed in a molecule. in , the major intermolecular forces are dipole-dipole interactions as the molecule is polar (bent structure). so the vanderwaal's forces of interaction in between molecules are the permanent dipole-dipole interactions that develop due to the dipole that exists in between the polar h - s bond. the positively charged hydrogen atom is attracted towards the negative end of the dipole that is sulfur of the adjacent molecule. therefore, these forces of attraction are relatively stronger than that of london dispersion forces that exist in non polar molecules.
