Expert Solution

1.correct answer:- epinephrine
Explanation:- Epinephrine is neurotransmitter of the sympathetic division of the nervous system that increases the heart rate and constricts smooth muscle in blood vessels to raise blood pressure in the "fight or flight" response.

2. Correct answer:- active immunity
Explanation:-active immunity- it is body's continuing immune response and defense against pathogens.

3. Correct answer:- folic acid and vitamin B12
Explanation:- deficiency of folic acid and vitamin B12 leads to megaloblastic anaemia.

4. Correct answer:- Lungs
Explanation:- pulmonology- it is the study of the lungs and associated structure.

5. Correct answer:- headache, sweating, and shakiness.
Explanation:- symptoms of hypoglycemia include- rapid onset of cool
pale
moist, and clammy skin
dizziness
headache
rapid pulse

6. Correct answer:- Emotion
Explanation:- Emotion means pertaining to the mood or state of mind.

7. Correct answer:- erythrocytes
Explanation:- erythrocytes are most numerous in blood.

8. Correct answer:- veins
Explanation :- veins carry to the heart.
Arteries carey blood from the heart.

9. Correct answer:- hypertension
Explanation:- Hypertension means elevated blood pressure.

10. Correct answer:- four
Explanation:- there are 4 chambers in heart-
2 atriam
2 ventricles.

The sympathetic nervous system uses epinephrine, or adrenaline, as a neurotransmitter and a hormone to exert its effects. These effects are often described as "fight or flight". Answer the following prompt: Epi-pens, which contain epinephrine, are used in people who are having severe allergic reactions. Specifically, these are used to improve breathing problems. Why do you think epinephrine helps in this case? What are two other effects an epi-pen may have as a side effect? Would injecting the epi-pen be more...

Explain how the sympathetic nervous system (and endocrine system) act directly to regulate heart rate and thus cardiac output. Include a detailed description of the mechanism (include the target cells, the proteins, signaling molecules, ions, and changes in membrane pontial where appropriate) and explain how the mechanism operates to alter heart rate.Explain how the parasympathetic nervous system acts to directly regulate cardiac output (1 mechanism). Discuss each mechanism separately including a detailed description of each mechanism (include the target cells,...

1) Select the CORRECT match: A. Peristalsis - increases with sympathetic nervous system stimulation B. Internal anal sphincter - under voluntary control C. Lacteals - lymph capillaries, transport chylomicrons D. Pancreas - synthesizes bicarbonate in response to CCK (cholecystokinin) E.
