Healthy Organs

• All living things are made up of cells.
• Cells are the building blocks of tissues, organs, systems, and organisms.
• The eight main organs are the Brain, Lungs, Liver, Large Intestine, Heart, Stomach, Kidneys, and Small Intestine.
• The three parts of the brain are the Cerebrum, Cerebellum and Medulla
• Cerebrum controls memory, personality, reasoning and inteligence
• Cerebellum is the balance and muscular co-ordination
• Medulla controls breathing rate and heart rate
• The heart is a muscular pump
• The heart pumps blood around the body
• The atrium is the top part of the heart
• In the heart the ventricle is the bottom part
• Large intestine absorbs water from food waste
• Heart pumps blood around body
• Lungs control respiration (breathing)
• Valves stop the blood from flowing backwards
• There are three different types of blood vessels: arteries, veins, and capillaries
• Arteries pump blood away from the heart
• Blood from the arteries is rich in oxygen
• Arteries do not have valves and they carry blood to the heart
• Veins carry blood to the heart
• Veins have oxygen pores
• Veins have valves
• Capillaries let gases pass from blood to surrounding cells
• Blood carries important substances to and from our cells
• Oxygen and food (like glucose) are carried to our cells by blood
• Carbon dioxide and waste are carried away from our cells by blood
• Water is carried around the body by blood
• Plasma is a cell, yellow substance found in blood
• Red Blood Cells (RBC) carry oxygen around the body
• White blood cells help to fight infection by producing antibodies and eating bacteria
• Platelets help the blood to clot and scab
• Red blood cells are concave in shape, lack a nucleus, and cannot reproduce to maximize space for oxygen
• Air travels down trachea into bronchioles which lead to alveoli where gas exchange takes place
• Pancreas produces insulin to regulate sugar levels
• Lungs are organs that take in air through nose or mouth
• Kidneys filter out waste products from blood
• Liver produces bile to digest fats
• Blood carries oxygen, nutrients and hormones to cells
• Small intestine digests food into nutrients
• The heart has four chambers - two atria and two ventricles
