Biology AS Unit 8 Transport in Mammals

a system that carries fluids around an organism's body

• pulmonary circulation

• circulatory system

• systemic circulation

• double circulation

the part of the circulatory system that carries blood from the heart to all of the body except the gas exchange surface, and then back to the heart

• pulmonary circulation

• circulatory system

• systemic circulation

• double circulation

the part of the circulatory system that carries blood from the heart to the gas exchange surface and then back to the heart

• pulmonary circulation

• circulatory system

• systemic circulation

• double circulation

vessel with relatively thin walls that carries low-pressure blood back to the heart

• artery

• vein

• capillary

• smooth muscle

vessel with thick, strong walls that carries high-pressure blood away from the heart

• artery

• vein

• capillary

• smooth muscle

the smallest blood vessel, whose role is to deliver oxygen and nutrients to body tissues, and to remove their waste products

• artery

• vein

• capillary

• smooth muscle

one or more layers of thin, flat cells forming the lining of some hollow structures, e.g. blood vessels and alveoli

• endothelium

• smooth muscle

• squamous epithelium

• Elastic arteries

a tissue that lines the inner surface of a structure such as blood vessel

• endothelium

• smooth muscle

• squamous epithelium

• Elastic arteries

arteries that are closer to the final destination of the blood inside them than elastic arteries, with more smooth muscle in their walls which allows them to constrict and dilate

• muscular arteries

• smooth muscle

• veins

• Elastic arteries

relatively large arteries, which have a lot of elastic tissue and little muscle tissue in their walls

• muscular arteries

• vasoconstriction

• vasodilation

• Elastic arteries
