structure of the respiratory system.

Nasal cavity- The nasal cavity is where the air enters and has hair and mucus to stop the diseases in the air.

Trachea- The Trachea is also known has the wind pipe and is positioned at the front of the throat.

Right lung- The right lung is slightly bigger than the left lung, because of where the heart is positioned.

Diaphragm-  The Diaphragm is a sheet of muscles that run under the lungs to create vacuum. It controls the lungs.

Epiglottis- The Epiglottis is like a door. It stops food from entering the respiratory system.

Larynx- The air passes through the sound box (Larynx).

Bronchus- Bronchus is made of two tube one entering one lung and the other entering the other lung. It transfer oxygen into the lungs.

Short term effects of Exercise on the respiratory system.

Our Heart rate increases, because our body needs blood and oxygen to combine glucose with it, to create energy and use that energy.

Amount of air inhaled and exhaled increases, because to provide more oxygen to our body, because you don't want your body lacking oxygen and keeping all the carbon dioxide inside during a high intensity exercise.

Your Tidal Volume increases due to the body, because it needs to get rid of carbon dioxide and breath in oxygen. Our muscles need oxygen and blood to create energy, so they can use it during the exercise.

Your heart rate increases due to the heart having to work harder to pump oxygenated blood around the body, so the blood vessels will be under high pressure, because of the blood that the heart is pumping. Over time the blood vessels become stronger so they can cope with this high pressure.

Your breathing rate increases, in order to supply more oxygen to your working muscles, also your lungs have to work at a fast rate for them to remove carbon dioxide and supply oxygen to the heart, and the heart puts blood into that oxygen (Oxygenated blood). This process has to happen really fast, so your muscles can keep up with the activity or they'll just slow down if your heart and lungs ain't working fast enough.

Long term adaptation on the respiratory system.

The respiratory system changes over time when your really working hard. Your lung capacity changes over time, because if you do more endurance work your lung needs to deliver loads of energy to your muscles, so over time it will take in loads of oxygen at once than taking it several times.

Your breathing rate will decrease , because your heart will become more efficient over time. It will pump loads of blood at once, than pumping less blood, but loads of times.

Your inter-coastal muscles will become stronger and it will allow your rip cage to expand when your breathing, so that you can take a big breath.

The diaphragm will get stronger and bigger, so that you can take bigger breath than usual.

Your capillaries gets bigger and that allows it to take significant amount of oxygen to your muscles.

There will be an Increase of efficiency to deliver oxygen and remove waste products, because your lungs will be use to working really fast.

Increased lung efficiency and gaseous exchange, because the of the intense aerobic endurance exercises.

Increased maximum oxygen uptake (V02 max). Increased Vital capacity (VC) - due to improved lung function (Vital capacity is the amount of air that can be forcibly expelled from the lungs after breathing in as deeply as possible).

Structure of the muscloskeletal system.

1. Your bicep and tricep are placed on the humerus( the long bone on your arm).

 2. Pectoral is on your chest you got two of them.

3. Rectus abdominal is beneath your pectoral, just covering your stomach.

4. Quadriceps are on your leg, the bone called femur. 

function of the muscloskeletal system.

1. Your bicep and tricep make your hand move up and down, also to pick stuff that your able to.

 2. Pectoral is there to protect your lung, inter-coastal muscles and diaphragm from getting damaged.

3. Rectus abdominal is to stop and damage happening to to our stomach, also our vital organs.

4. Quadriceps allows you to run as fast has you can and move your leg around, also it controls how fast you can move.

Function of the skeletal system.

There are 5 main function of the skeletal system. 

1. Shape-  Shape is the key thing in our body, if we didn't have shape we would just be a jelly.

2. Movement- Movement is done by contracting your muscle. Your muscles are around your bone, allowing it to move. 

3. Protection- Our bones protect our vital organs, because our vital organs are very delicate it can't handle the pressure we put on every.

4. Blood production- Red marrow bone is responsible for making red/white blood  cells. They make the red/white blood cell inside the bone.

5. Mineral storage- The bones in our body store special things. Calcium is very important for our bones, because it makes our bones stronger and bigger, also more efficient. 

Structure of the skeletal system.

When your born you start with 350 bones in your body. As you grow up some bones join up and become one, so you'll have less bones. When you turn and adult the bones stop fusing and joining up together, by that time you should roughly have about 206 bones in your body.

1. Long bones- Long bones are found in the arm and legs, they're longer than they are wide, also they have marrow bone inside them.

2. Short bones- They bones are found on the ankles, wrist, fingers and on the feet. They're cube shaped bones. Small, but very strong.

3. Flat bones- These type of bones are very strong, so they can protect the vital organs (brain, heart and lungs).
