- Digestive organs
- Circulatory system
- The heart
- Right ventricle pumps blood to the lungs
- Left ventricle pumps blood round the body
- Vessels in the heart
- Aorta
- Vena cava
- Pulmonary artery
- Pulmonary vein
- Coronary arteries
- The lungs
- Trachea
- Bronchi
- Bronchioles
- Alveoli where gas exchange occurs
- Blood vessels
- Viens
- Take deoxygenated blood into the heart
- Have thinner walls, low pressure and valves in case of backflow
- Arteries
- Takes oxygenated blood away from the heart around the body
- Have thick walls and high pressure
- Capillaries
- One cell thick
- Carry blood away from arteries, into organs and back into veins
- Viens
- The heart
- Blood
- Plasma
- Liquid that carries all the blood cells
- Platelets
- Small cells that allow blood to clot at the site of a wound
- Red blood cells
- Transport oxygen through blood. Have haemoglobin
- White blood cells
- Lymphocytes
- Produce antibodies that latch onto antigens on pathogen
- Phagocytes
- Engulf pathogen by process of phagocytosis
- Fight off pathogens in body
- Lymphocytes
- Plasma
- Coronary heart disease
- Atherosclerosis
- The build up of fatty deposits in the coronary arteries
- Stents
- Small wire frames that fit into the arteries and stop them from clogging up
- Statins
- Drugs that reduce cholesterol that slow down the rate of fatty deposits
- Atherosclerosis
- Plants
- Tissues and organ systems
- Epidermal tissue
- Palisade Mesophyll
- Spongy mesophyll
