We’ve learnt about the components of blood
Plasma
Platelets
RBC_ Red blood cells
WBC_ White blood cells
We also learnt that RBC contains hemoglobin which helps it trap oxygen and  that WBC protect our body from infection

We’ve also learnt about Gas exchange which comes under Respiration.
During gas exchange oxygen moves from our lungs to our blood.at the same time carbon dioxide passes to our lungs .

AEROBIC respiration
Blood carries oxygen and nutrients to all cells in the body.

Diffusion
The part where particles with high concentration spread to particles with low concentration

Breathing
When your muscles move to get air in and out ofyiur lungs
The number of times you breath in a minute is your breathing rate the process contains exhaling and inhaling

# data[].attributes.body
Parts of blood
Red bloodcells, white bloodcells, plasma, and platlets
red blood cells contain hemoglobin and ha a boconcave shape
white blood cells fight away the germs

Human Respiratory System
The parts we learnt:
Trachea, larynx, pharynx, Bronchi, Bronceols, and alveoli
we learnt about the capillaries and the gas exchange in lungs. We learnt about celiated ephitelial cells and we also learnt about the goblet calls

we learnt about breathing , when you breath you breath, you breath in oxygen through the trachea then the bronchi, broncheols, alveoli and al the way to the gas exchange where the capillaries are and this is called respiration and where it produces energy and then the waste energy will exhale that takes out carbon dioxide

# data[].attributes.body
The lungs contain many pockets called alveoli . oxygen diffuses into blood with the help of alveolus. We also made a  diagram on components of blood .

Our blood has 4 components

1 : PLATLETS

Platlets help blood to form clogs near cuts or any kind of hurts
2 : RED BLOOD CELLS
The red blood cells contain hemoglobin which gives it the red color and transports oxygen and has no nucleus
3:White blood cell
White blood cells help us in fighting diseases
4:Plasma
Plasma carriers the RBC WBC and the platlets throughout the body

GAS EXCHANGE.
In our lungs we have a part called alveoli our gas exchange takes place give out carbon dioxide and take in oxygen . During gas exchange oxygen moves from the lungs into the blood stream and carbon dioxide passes through the blood and into the lungs

BREATHING
BREATHING is a process of moving air in and out through the lungs

we have learned about the difference between respiration and breathing. respiration is taken place in the cells mitochondria while breathing takes place in the lungs. respiration is when oxygen + glucose makes carbon dioxide + water and breathing is when your respiratory system muscles move. There are many things in the blood such as  RBC,WBC(machrophage and neutrophils),platelets and plasma. RBC contains hemoglobin and has no nucleus. WBC fight certain pathogens and viruses and are very flexible. Platelets clot blood when there is a wound. Plasma transports RBC through the body  and contain carbon dioxide and excess water.

BLOOD
The components of blood include plasma (a yellow liquid) that carries red blood cells (that give the blood its color), white blood cells (or soldier cells that fight foreign bodies such as viruses), and carbon dioxide.

RBC
RBCs or red blood cells have hemoglobin that carries oxygen to different parts of the body. They have no nucleus and a biconcave shape for more space to store oxygen. They don't have any mitochondria as they need to carry the oxygen and the mitochondria would take up the oxygen for respiration.

RESPIRATORY SYSTEM
The respiratory system's function is to send oxygen to all parts of the body. first, you breathe in air through your mouth or nose which goes down the trachea or windpipe, then to the bronchi which become bronchioles which go to the alveoli in the lungs where they diffuse. When you breathe in, the diaphragm and the intercostal muscles contract and your lungs expand, and when you breathe out the diaphragm, the intercostal muscles and your lungs relax

Blood:
We learned about the components of blood and what they do. The three components of blood are plasma, white blood cells(WBC) and red blood cells(RBC). Platelets are another part of blood and the help us clot blood when we are injured

The functions are:
Plasma carries carbon dioxide and nutrients
WBC is the first line of defense for the immune system and kills bacteria
RBC use hemoglobin to capture and transport oxygen

WBC and RBC are specialized cells and have certain adaptations to help them

Red Blood Cells have no nucleus to increase space for hemoglobin and have no mitochondria as they use oxygen and it will reduce the efficiency of the red blood cells.
They are produced in the bone marrow with white blood cells as well. They have a lifespan of about 1 week.

White Blood Cells are flexible so they can squeeze into possible spots where bacteria might be at. They self destruct or die after they eat many germs and bacteria.

Respiration:
We learned about the part of the respiratory system, which are the nasal cavity, the trachea, the bronchi, bronchioles and alveoli.
We learned that oxygen passes through the nasal cavity or oral cavity through the trachea, bronchi, bronchioles and finally to the alveoli.
We learned that the alveoli increase the surface area for oxygen to diffuse to the blood in the capillaries. There are ciliated epithelial cells which have celli to brush mucus produced from the goblet cells away from the lungs and stop germs from going into the lungs.
Alveoli have capillaries around them where the oxygen diffuses to as there is less oxygen in the deoxygenated blood which is in the capillaries there and vice versa for carbon dioxide.
Aerobic respiration is a chemical reaction where oxygen and glucose react to form energy.
The diaphragm and intercostal muscles help us breathe by expanding and contracting the lungs by relaxing and contracting.

Blood is a liquid tissue that carries substances around the body.
Blood vessels are tube-shaped organs that carry blood around the body.
Circulation is the movement of blood around the body.
Capillaries are tiny blood vessels found in tissues of your body, and are only 1 cell thick.

---------------------------

Parts of the respiratory system are the nose, mouth, throat, nasal cavity, oral cavity, pharynx, larynx, airways, lungs, alveoli, intercostal muscles, and the diaphragm.

Ciliated Epithelial Cells use cilia to sweep the mucus up your throat so it doesn't reach your lungs.

Oxygen + Glucose -> Carbon Dioxide + Water
(O2 comes from the air we breath, and Glucose comes from the food we eat)
This is called Aerobic respiration

There is approximately 300 million alveoli in our lungs

Breathing is a mechanical process while respiration is a chemical process that occurs in the mitochondria of the cell.

O2 diffuses from the alveoli -> blood
CO2 diffuses from the blood -> alveoli
The lining of the alveoli is called a membrane.

Diffusion is the movement of particles from higher to lower concentrations. It happens naturally.

When you inhale, the diaphragm contracts, and when you exhale it relaxes.

When neutrophils corner the bacteria and destroys it, the process is called phagocytosis.

To measure your BPM, we usually count the amount of beats in 15 seconds, then multiply that by 4 to get the approximate amount.

Components of blood-
RBC 44% The function of Red Blood Cells is to absorb oxygen, it has a bio-concave shape to absorb more oxygen
WBC and Platelet 1% White Blood Cells are known as solider cell, they are flexible to fit in to tight places and platelets are used for healing wounds.
Plasma 55%

Parts of Respiratory system-
Lungs, Alveoli, Pharynx, Larynx, Bronchi, Nasal Cavity, Bronchioles and Oral Cavity

BREATHING
When you inhale the air goes through your trachea. From trachea it goes through the bronchi and Bronchioles and finally in to the lungs.
In the lungs the air goes in to the alveoli (where gas exchange takes place). When you breathe in the Diaphrum contracts.
