In what ways are alveoli good for gas exchange?
They are moist and have thin walls- gasses can easily diffuse in and out of them, also they have a large surface area

3 main microbes include
Bacteria, Virus and Fungi

White blood cells fight them by
Producing antibodies and andtitoxins. Antibodies neutralise them. They also enguf the pathogen. ANtibodies neutralise and clump pahthogens so they can be enguulfed

Other immunity
Vaccines- inlcude dead or mutilated microbes. Antibacterial- kills bacteria. External immunity- skin,tears etc

Carboryhdrates-What are they for and what happens if you dont get enough?
They are needed for energy and if you dont get enough you wont have enough energy and will feel weak
9 of 32
Proteins- " "
We need them for growth and repair and if you dont get enough, you might have growth problems and wounds would take longer to hearl
10 of 32
Fat
Needed for Energy storage, Insulation and protection. If you don't get enough, organs would be less protected, you'd have less energy and would feel more cold
11 of 32
Minerals
The minerals in our diet are essential for a variety of bodily functions. They are important for building strong bones and teeth, blood, skin, hair, nerve function, muscle and for metabolic processes such as those that turn the food we eat into energ

Vitamins
Keep body healthy and prevent deficiencies.
13 of 32
Vitamin C
Keeps skin strong. If you don't get enough, youd get scurvy
14 of 32
Vitamin D
Helps bones harden. If you dont get enough youd have rickets and bones stay soft and could deform. Vitamin D can be obtained through Eggs,Cod liver oil and is made in skin when in sunlight

Iron
Needed for making red blood celss. If you don't get enough, you'd feel rired and look pale and aenemic. Found in green veg and dark chocolate

Water
Vital for all body processes

What is the Respiratory system for?
The primary function of the respiratory system is to supply the blood with oxygen in order for the blood to deliver oxygen to all parts of the body. The respiratory system does this through breathing. When we breathe, we inhale oxygen and exhale

What is the trachea for?
The trachea is also known as windpipe. The trachea filters the air we inhale and branches into the bronchi.
19 of 32
Diaphragm:
Breathing begins with a dome-shaped muscle located at the bottom of the lungs which is known as diaphragm. When we breathe in the diaphragm contracts and flatten out and pull downward. Due to this movement the space in the lungs increases
20 of 32
The intercostal muscles
control the movement of the ribs. They move up and out when the muscles contract and they move down and in when the muscles relax.
21 of 32
Why does the trachea have cartilage rings?
To support the trachea and to stop it from collapsing
22 of 32
Blood with ____ levels of O2 leaves the lungs
High
23 of 32
Blood with ____ levels of O2 enters the lungs
Low and Enters
24 of 32
In the blood there are 4 cells
Red blood celss- carry O2 to the cells. White blood cells- immunity. Platlets- clot blood. Plasma- keeps the three cells moving
25 of 32
The left side of the heart is stronger because?
It's got oxgynated blood, it has to pump blood all around the body
26 of 32
The right side is weaker because?
It's got deoxgynated blood which only has to pump blood to the lungs
27 of 32
3 things the Capillaries do
Supply O2 to cells. Supply Nutrients to cells. Remove waste- CO2
28 of 32
The right side of the heart has _____ blood
deoxgynated
29 of 32
The left side of the heart has _______ blood
oxgynated
30 of 32
Pulmonary vein is the only vein to carry oxgynated blood because?
It's just been to the lungs
31 of 32
Pulmonary artery is the only vein to carry deoxgynated blood because
it's going to the lungs to pick up O2
