What is open circulation? provide examples
In this type of circulation, blood is pumped into a cavity instead of enclosed vessels.
example: insects
What is the epidermis?
This is the outermost layer of the leaf that protects it from water loss.

Pulmonary system?

Two types of cambium
vascular and cork.
Systemic circulation
The circulation of blood through the arteries, capillaries, and veins, of the general system
What are guard cells?
