Answer:
The hepatic portal circulation is responsible for collecting the nutrient-rich venous blood draining from the digestive viscera.
Explanation:
The venous blood draining from the digestive viscera, present in the digestive system, that is rich in nutrients is returned to the liver via the hepatic portal circulation for further processing and detoxification. The hepatic portal circulation, also known as the portal venous system, consists of the hepatic portal veins.
Cognitive-behavioral techniques: a. may substitute for drug treatments in case of severe hypertension. b. can be used without supervision and have no side effects. c. are expensive and highly difficult to implement. d. have been moderately successful in the treatment of hypertension.
Answer:
C. can be used without supervision and have no side effects
Explanation:
Cognitive behavior therapy is a type of approach in behavior modification where the therapist/doctor looks at other factors that may affect the well-being of that person; finding goals to help change their behaviors.
In this case; what is causing the hypertension and what they can do to counter that "problem" without drugs.
The correlation between drinking alcohol and illicit drug use is: A) negative—drinkers are less likely to use illicit drugs than nondrinkers B) random—drinkers are equally as likely to use illicit drugs as nondrinkers C) positive—drinkers are more likely to use illicit drugs than nondrinkers D) unknown and unknowable with any available data
Answer:
The correct answer is c) positive- drinkers are more likely to use illicit drugs than nondrinkers.
Explanation:
Many surveys have been conducted by the CASA, which is National Center on Addiction and Substance Abuse at Columbia university and by National College Risk Behavior survey, also by Core Alcohol and Drug survey, and from all these surveys one thing that has come out as common is that the use of illicit drugs such as Tobacco , LSD, Marijuana is more common among those who are drinkers or you can binge drinkers than the ones who don't drink.

Which would occur if the retina is damaged?
The image will not be transferred to the back of the eye.
The eye cannot adjust for differences in light intensity.
Incoming light will not be focused onto the lens.
Nerve impulses will not travel down the optic nerve.
Answer:
Nerve impulses will not travel down the optic nerve.
Explanation:
If the retina is damaged, nerve impulses will not travel down the optic nerve.
Answer:
Nerve impulses will not travel down the optic nerve.
Explanation:
The retina is one of the membranes of the posterior follow-up of the eye, whose function is to transform the light stimulus into a nerve stimulus. The nerve membrane of the eye and its territory extend from the optic nerve to the pupil. It is formed by ten layers, of which stand out the pigment epithelium (the outermost layer) and the sensory layer (composed for photoreceptors). For this reason, we can conclude that if the retina were damaged the nerve impulses would not travel through the optic nerve.
Valve between right atrium and right ventricle is called
The answer is the Tricuspid Valve.
Answer: Tricuspid Valve
Explanation: The tricuspid valve is the valve between the right atrium and the right ventricle. It’s important to the pumping of the blood throughout the body.
The effects of general anesthesia are mediated by which receptors?
A) Both GABA and NMDA receptors in the CNS
B) Both GABA and NMDA receptors in the PNS
C) Mainly GABA receptors in the CNS
D) Mainly NMDA receptors in the CNS
Answer:
(A). Both GABA and NMDA receptors in the CNS
Explanation:
General anesthesia or general anesthetics can be defined as substances that triggers a loss of consciousness in individuals. These medications show their effect by activating inhibitory CNS and by inactivation of excitatory receptors of CNS.
They target both GABA (gamma-aminobutyric acid) and NMDA (N-methyl-D-aspartate) receptors of CNS. General anesthetics agonist effect with GABA receptors and antagonist effect with NMDA receptors, and induces state of unconsciousness.
Thus, the correct answer is option (A).
Why is a person with type AB blood able to receive a blood transfusion from a donor with any of the major blood types (A, B, AB, and O) but is able to donate blood only to another type AB individual? Match the words in the left column to the appropriate blanks in the sentences on the right.
I believe the correct answer is the presence of antigens.
Explanation:Red blood cells have specific antigens on their surface that determine the blood group are hereditable. For example, blood group A means the person has the A antigen, B means the B antigen and AB means the person has both A and B antigens. The other group is blood group O and that means the person lacks the antigens to to make a particular blood group. The human body produces other chemicals called antibodies that attacks antigens and that is why you can only recieve a blood group that is yours to prevent the antibodies from attacking you. Since there are only 2 antigens, a person with antigen A produces antibodies against the rival antigen B. In the case of blood group AB where a person has both antigens, the body lacks all the antibodies in order to prevent the body from attacking itself. So a person with blood group AB lacks antigens a and b.This means the person can receive blood from any blood group since there are no antibodies to attack any antigen. They however can only donate to a person who has the same AB bloodgroup since all the other blood groups have antibodies against antigens and adding blood that has antigens will cause a severe blood transfusion reaction.
Which of the following is a key factor that contributes to reemerging disease? a. Deforestation leads to encroachment of the biological reservoir into densely populated regions. b. Climate change allows vectors to spread to new equatorial regions. c. Increased antibiotic resistance in a well-known pathogen leads to increased incidence rates. d. Increased international travel brings a pathogen to continents with no prior disease incidence.
Answer:
c. increased antibiotic resistance in a well known pathogen leads to increased incidence rates.
The correct option is d. Increased international travel brings a pathogen to continents with no prior disease incidence.
Reemerging diseases are infectious diseases that have appeared in a population, then declined significantly, but are now on the rise again. The spread of these diseases can be influenced by several factors, including:
a. Deforestation leads to encroachment of the biological reservoir into densely populated regions: This can indeed contribute to the spread of diseases, as it brings humans into closer contact with wildlife and their pathogens. However, this is more about the emergence of new diseases rather than the reemergence of diseases that have previously declined.
b. Climate change allows vectors to spread to new equatorial regions: Climate change can enable disease vectors, such as mosquitoes, to expand their range into areas where they were previously unable to survive. This can lead to the spread of diseases like malaria or dengue fever to new regions. While this can contribute to the reemergence of diseases, it is not as direct a factor as international travel.
c. Increased antibiotic resistance in a well-known pathogen leads to increased incidence rates: Antibiotic resistance is a significant public health concern and can lead to the resurgence of certain bacterial infections. However, this factor is more about the increased difficulty in treating a disease rather than its initial spread to new areas.
d. Increased international travel brings a pathogen to continents with no prior disease incidence: This is a key factor in the reemergence of diseases. International travel can rapidly spread pathogens across the globe, introducing them to populations that may have no immunity to the disease. This was evident in the global spread of COVID-19, where international flights played a crucial role in the rapid dissemination of the virus.
Therefore, option d is the most direct and significant factor contributing to the reemergence of diseases on a global scale. It allows for the quick movement of pathogens from one part of the world to another, potentially leading to outbreaks in immunologically naive populations.

Thanks for submitting your question to Brainly!
It looks like the answer to this question is : D) It uses realism to shock people into awareness
Explanation:
Most anti-nicotine advertisements use the real effects of the drug to not only stop people from using it, but also to prevent others from trying it.
An elderly man is brought to the clinic because he fatigues extremely easily. An examination reveals a heart murmur associated with the bicuspid valve during ventricular systole. What is the diagnosis? What is the possible treatment?
The elderly man with extreme fatigue and a heart murmur during ventricular systole likely has mitral valve prolapse. Treatment may involve medication or, in severe cases, surgical repair or replacement of the mitral valve.
An elderly man experiencing extreme fatigue and a heart murmur associated with the bicuspid valve during ventricular systole likely has mitral valve prolapse or another form of mitral valve disease. In this condition, the mitral (bicuspid) valve is unable to close completely, causing regurgitation of blood back into the left atrium during systole. This results in insufficient blood flow into the systemic circulation, contributing to the symptoms including fatigue. Possible treatments for mitral valve prolapse may include medication to manage symptoms, such as beta-blockers or diuretics, and in severe cases, surgical options like mitral valve repair or replacement surgery may be necessary. If a heart valve is significantly damaged, the surgical installation of artificial heart valves may be considered to restore proper heart function and improve the patient's quality of life.
