Write a summary of the above 2 outcomes on your own wiki.
1. Explain the relationship between cells, tissues, organs and systems.
A cell is a single unit of organism. when many cells form together, tissues are formed. so when loads of tisssues come together, organs are formed.

2. State, with examples that organs are a group of tissues that coordinate to do a specific job.
Heart: The hearth works like a pump to transport blood around your body.
Lungs: The lungs take in the oxygen from the air and give to the blood vessels that run next to them
Skin: The human skin lets sweat out and protects your body from harmful things.(chemicals, poison, etc.)


  1. Label a diagram of the respiratory system (trachea, bronchi, bronchioles, alveoli).
  2. Explain how air enters and exists the lungs.
Air enters when the diaphragm is lowed due to the movement of muscles. The low pressure in the chest cavity causes air from to the outside to rush into the lungs
  1. Describe the process that occurs inside an alveolus
  2. When air goes into the alveolus, there is an exchange of gases between the alveolus and the blood in the capillaries surrounding the alveolus. Oxygen moves by different from the alveolus into the blood and carbon dioxide moves from the capillaries into the alveolus to be breathed out through the nose.

  1. State the function of each of the following components of the circulatory system: arteries, veins, capillaries, heart., blood.
Arteries: Takes blood from the heart and transports it around the body
Veins: Takes the blood back to the heart
Capillaries: Carry materials such as oxygen and nutrients to the cells and remove waters
Heart:Biological pump that circulates your blood around your body
Blood: to carry nutrients such as glucose to carry waste, carry oxygen and to fight disease and to clot when there is a cut so the cut is sealed
  1. Describe the function of the main components of blood (plasma, red and white blood cells and platelets).

terminology list
Organs, cells, tissue, heart, lungs

The Body Video
Organs of the respretory systems
The tiny biconcave RBCs contain haemoglobin that attaches oxygen to be carried around the body
The larger WBCs fight diseases by engulfing germs some WBCs produce antibodies that attack germs
Plama is a straw-coloured liquid which mostly consists of water, nutrients such as and glucose and watse products such as carbon dioxide are carried around the body in the plasma
Platelets help to clot blood when a blood when blood Biological pump that circulates your blood around your blood Biological pump that circulates your blood around your bod vessels is cut.
  1. The part of your body called the diaphragm is expanded to force the air from your lungs, when it relaxes the pressure forces the air back into your lungs, this cycle is just repeated, as you continue to breathe.
Body system
  • Our heart pumps the blood around our body
  • The heart is attached to the lungs by lung vessels
  • Cardio=heart
  • Biological pump that circulates your blood around your body
  • Vascular=blood
  • The blood takes oxygen


11. Give examples of life saving technology that have arisen as a result of improved understanding of the circulatory system (artificial heart valves, ECG and artificial blood).

  1. Label a diagram of the respiratory system (trachea, bronchi, bronchioles, alveoli).
  2. Explain how air enters and exists the lungs.
Air enters when the diaphragm is lowed due to the movement of muscles. The low pressure in the chest cavity causes air from to the outside to rush into the lungs
  1. Describe the process that occurs inside an alveolus
  2. When air goes into the alveolus, there is an exchange of gases between the alveolus and the blood in the capillaries surrounding the alveolus. Oxygen moves by different from the alveolus into the blood and carbon dioxide moves from the capillaries into the alveolus to be breathed out through the nose.

  1. Describe the function of the excretory system.
Is to remove the metabolic wastes of an organism. Wastes that are removed include carbon dioxide, water, salt and urea
  1. Label the urinary system.

Recall the function of the following parts of the urinary system: kidney, bladder, ureters, urethra.
Kidneys- 2 kidneys constantly filter blood produce urine
Ureters- 2 ureters carry urine from the kidneys to the urinary bladder.
Bladder- the urinary bladder stores urine until it is released from the body
Urethra- is the tube that carries urine from the urinary bladder to the outside of the body
