The arteries get "hard" and absorb less systolic force
Answer:
1. The dermal layer of the plant is known as epidermis which is outermost thin layer of plants where stomata are found.
2. The dermal layer is like epidermis in human skin which is also a outermost layer and provides a waterproof barrier .
3. The waxy barrier in the epidermis of plant leaf is called the cuticle act as a protective layer and prevent water loss.
4. Stomata are the tiny pores present on the surface of leaves that control the exchange of gases (CO2 and O2) and regulate water loss by opening and closing.
5. The main function of dermal layer (epidermis) is to protect the soft tissues of plants and regulate its interaction with surrounding. Dermal layer act as outermost layer and protect plant leaf and also secret the cuticle that inhibits water loss.
The main responsible for the delay among the atrial and
ventricular contractions is the action potential conduction velocity of the AV
node cells. If the atria and ventricles contract simultaneously, atria cannot
give any help in filling the ventricles, which is needed, especially in those
with stiff ventricles as in the elderly. Hence atria have to contract first and
then the ventricles.
