  • Pasta
  • Potatoes
  • Bread

Proteins are good. The provide us help to grow and replenish.
Some examples of Proteins are:

Study Notes for the Circulatory System:
  1. Arteries: hollow tubes with thick walls carrying blood pumped from the heart to other parts of the body

Veins: blood vessels that carry blood back to the heart. They have vales and thinner walls than arteries

Capillaries: minutes tubes carrying blood to body cells. Every cell of the body gets blood through capillaries

Capillaries carry blood to all cells of the body and removes things like carbon dioxide and water

Heart: a muscular organ that pumps blood around the body

  1. Describe the function of the main components of blood (plasma, red and white blood cells and platelets).
    • To carry nutrients such as Glucose
    • To carry wastes such as Carbon dioxide
    • To carry oxygen around the body
    • To fight disease
    • To clot when there is a cut so the cut is sealed

Blood is composed of:


Red Blood Cells

White blood cells


Functions of Red Blood Cells

The tiny biconcave contains haemoglobin Red Blood Cells (RBC's) that attaches oxygen to be carried around the body.

Functions of White Blood Cells

The larger White Blood Cells (WBC's) fight diseases by engulfing germs. Some WBC's produce antibodies that attack germs

Functions of Blood Plasma

Plasma is a straw-coloured liquid which mostly consists of water. Nutrients such as glucose and waste products such as carbon dioxide are carried around the body in the plasma.

Function of Platelets

Platelets help clot blood when a blood vessel is cut.

Body Systems

  • The heart is the biological pump that starts the blood
  • Cardio refers to the heart
  • Vascular- blood
  • Structures forms a transport system
  • Transports oxygen to the cells in your body
  • The blood takes oxygen to your cells and returns your oxygen to your cells
  • The heart is attached to your lungs

  • Pulmonary Artery carries blood from the heart to the lungs.
  • Artery is a blood vessels that carries blood from the heart to some other part of the body

  • Pulmonary mean lungs

  • Blood returns from the lungs to the heart by the pulmonary vein
  • Anything to do with lungs is pulmonary
  • Another large vessel is called the Aorta
  • It carries blood from the heart from the heart to the rest of the body
  • Blood leaves the heart through the Aorta

  • The Aorta divides into 2 arteries and arteries divide into capillaries in the tissue

  • Veins join together to form the Vena Cava

Terminology for the digestive system:
Mouth- the beginning of the digestive system. Chew the food and is swallowed
Esophagus- the Esophagus gets food from the mouth. It is a soft muscular tube, that takes food from the pharynx to the stomach.
Stomach- the stomach is an organ that has a strong lining that is a highly acidic environment needed to break down food
Pancreas- the pancreas makes hormones including insulin, to regulate blood glucose level
Appendix- the appendix is attached to the cecum. When it gets inflamed, you have what's called appendicitis. You can have your appendix removed.
Small Intestines- the small intestines takes food from the stomach and into the large intestines.
Large intestines- the large intestines lead into the rectum
Rectum- the rectum takes the waste and it is held there until it is finally released.
Anus- the anus is the last part of the digestive system, the feces get released.

Study Notes for the Respiratory System

  • The respiratory system is when you breath in and out
  • The system involes the following: Trachea, Bronchi, Lungs and the Diaphragm
  • When you breath in airs travels down your windpipe (trachea) then through the bronhci and into your lungs. When you breathe in your diaphragm inflates. When you breath out your diaphragm deflates.
