Answer:
The function of stratified epithelium is mainly protection.
Explanation:
Answer:
The answer is- Increased blood glucose, decreased GI peristalsis, and increased heart rate and blood pressure
Explanation:
The sympathetic nervous system (SNS) is a branch of the Autonomic Nervous System (ANS). Sympathetic Division of the ANS responds to threats- to fight or to run away. The stimulation of the sympathetic nervous system causes vasoconstriction of most blood vessels, including those of the digestive tract, skin and the kidneys.
It does the following;
- Increases the rate and strength of contraction of the heart
- Dilates the bronchioles of the lungs
- Decreases movement in the stomach and intestines (decreasing GI peristalsis)
- Increases the breakdown of glycogen and release of glucose from the liver thereby increasing blood glucose
- It dilates the pupil
- increases sweat secretion from the sweat glands
- constricts blood vessels of the skin
- Dilates blood vessel of the skeletal muscle
- Constricts blood vessels of internal organs except the heart and the lungs.
- Relaxes the muscle wall of the urinary bladder
- Stimulates hormone (epinephrine and norepinephrine) secretion from the adrenal medulla
NOTE: GI is Gastrointestinal tract
