Discuss the difference between chronic and acute pain

OLga [1]

Acute pain is the body's normal response to damage such as a cut, an infection, or other physical injuries. This type of pain usually comes on fast and often goes away in no more than a few weeks or months if treated properly. Acute pain can become chronic when the cause is difficult to treat.
Chronic pain, according to the VHA, "generally refers to intractable pain that exists for three or more months and does not resolve in response to treatment." It is viewed more as its own disease rather than as a symptom of another health problem. It can be affected by physical (sitting or standing), environmental (weather changes), and psychological (such as stress) factors. Chronic pain often cannot be treated or cured; it can only be managed. Therefore, chronic pain may reduce quality of life, well-being, and ability to function over the long term.

loris [4]

Answer;

The above statement is true

Explanation;

-Complement is a system of plasma proteins that can be activated directly by pathogens or indirectly by pathogen-bound antibody, leading to a cascade of reactions that occurs on the surface of pathogens and generates active components with various effector functions.

-C3b is the larger of two elements formed by the cleavage of complement component 3, and is considered an important part of the innate immune system. C3b is potent in opsonization: tagging pathogens, immune complexes (antigen-antibody), and apoptotic cells for phagocytosis.

Which statement is true about the male reproductive system?

umka21 [38]

Answer:

C. The scrotum functions to keep the testes at an optimum temperature.

Explanation:

In order to understand the correct answer, we need to review basic anatomy and physiology of male reproductive system.

Testes also known as testicles are paired organs located in the scrotum (bag of skin and smooth muscle) suspended from the body. Testes are responsible for the formation of sperms. Scrotum keeps the testicles away from the body. It provides a temperature cooler than the body temperature which is necessary for formation of sperms (Spermatogenesis). Sperms mix with other secretions from various internal genital organs (prosate, Cowper's glands, seminal vesicles) to form semen. Sperms constitute a very small proportion of semen.

Semen is deposited by the penis into vaginal tract from where the sperms travel to uterus.

Coming back to the answer choices,

A. The testes produce semen.

Testes produce sperms and semen is formed after sperms mix with other secretions of organs of male reproductive system.

B. Sperm cells are the largest component in the composition of semen.

Sperms constitute a small proportion of semen. Other components of semen include fructose, fibrinogen, coagulants, cholesterol etc.

C. The scrotum functions to keep the testes at an optimum temperature.

This is the correct answer choice as scrotum keeps testicles away from the body at a suitable temperature for spermatogenesis.

D. The penis enables sperm to be deposited directly into the uterus.

Penis deposits semen into the vaginal tract from where sperms travel to the uterus.
