Front 26

What can cause coronary heart disease?

Back 26

When the arteries are narrowed by a build up on fatty deposits.

Back 32

A strong sheet of muscle that separates your lung cavity from other internal organs.

Front 33

Which part of the lung is used for gas exchange and why is it efficient.

Back 33

Alveoli because they have a large supply of capillaries with a large surface area.

Front 34

What does air enter the lungs by?

Back 34

Trachea and the Bronchi

Front 35

What are the two transport tissues in plants and what do they carry?

Back 35

Xylem carries water and dissolved mineral ions from root to leaf.

Phloem carries dissolved food from leaves around the plant.

Front 36

What is the surface tissue of a leaf called?

Back 36

Epidermal Tissue

Front 37

The phloem moved dissolved sugars from the leaves to the rest of the plant. What is this called?

Back 37

Translocation
