Unit 2-Transport systems (Animals) Flashcards
Transports nutrients, oxygen and carbon dioxide around the body
Blood
Pumps blood around the body
Heart
The side of the heart that contains deoxygenated blood
Right
The side of the heart that contains oxygenated blood
Left
Where the deoxygenated blood becomes oxygenated
Lungs
Thin walled chambers at the top of the heart
Atrium
Thick walled chambers at the bottom of the heart
Ventricles
Between the atria and ventricles to prevent the backflow of blood
Valves
Blood vessel that brings blood from the body to the right atrium
Vena Cava
Blood vessel that transports blood from the right ventricle to the lungs
Pulmonary artery
Blood vessel that transports blood from the lungs to the left atrium
Pulmonary Vein
Blood vessel that transports blood from the left ventricle to the body
Aorta
Blood vessel that provides the heart muscle with oxygen and glucose
Coronary artery
Blood vessels with thick muscular walls that carry blood under high pressure
Arteries
Blood vessels with thin walls and valves that carry blood under low pressure
Veins
Blood vessels that are thin walled to allow exchange of materials with cells
Capillaries
Characteristics of capillaries that make them efficient for the exchange of materials with tissues
Thin walled Large surface area Extensive network
Cells that transport oxygen
Red blood cells
Molecule in red blood cells that combines with oxygen in the lungs
Haemoglobin
Molecule formed when haemoglobin combines with oxygen
Oxyhaemoglobin
Type of white blood cell which engulfs pathogens
Phagocyte
Type of white blood cell which produces antibodies
Lymphocyte
