Answer:
pushes both types of blood to both the lungs and body.
Explanation:
These fibers transmit the electrical impulse to the myocardium (cardiac muscle). The myofibers in the ventricular myocardium contract at the same time because the impulses are transmitted rapidly. When the ventricles contract, the blood from both ventricles is forced out through the pulmonic and aortic valves into the pulmonary and systemic circulation.
The electrical shock causes the heart's ventricles to contract and pump blood as it moves along the conduction channels, hence option B is correct.
What is ventricular myocardium?Before the two lower chambers of the heart may contract, the two upper chambers of the heart (atria) are activated first (ventricles).
Cardiomyocytes and fibroblasts make up the majority of the cells in the myocardium. Along with the extracellular matrix (ECM), blood arteries, lymphatic vessels, and nerve terminals, fibroblasts are dispersed throughout cardiomyocytes.
A thin layer of connective tissue connects the myocardium to the endocardium, the deepest layer of the heart wall.
Therefore, the heart valves are protected by the endocardium, which also borders the blood circulation chambers, hence option B is correct.

A 100-meter sprint is a race using only the straight side of a racetrack. A 400-meter sprint is a race that makes one complete lap around a racetrack. Why are velocity and speed the same for a 100-m sprint but not a 400-m sprint?
Answer:
it is possible
Explanation:
it is so because velocity and speed differ each other by direction. in a 100 m sprint race ,the person moves in a straight path without changing its direction where as in a 400 m race , the person moves in a lap around the race track and the direction changes as he turns according to the race track.
Answer: In the 100-m sprint, the displacement is 100 meters and the distance is 100 meters. This means speed and velocity are the same for the 100-m sprint. In the 400-m sprint, the distance is 400-m, but the runners stop at the same place they start so the displacement is zero. Zero displacement means zero velocity.

Which statement about detoxification is true? Most people are able to make lasting changes after detoxification. It is only the first step in treatment. It is rarely needed for successful treatment. It usually occurs outside of a formal treatment setting.
Answer: It is only the first step in treatment.
Explanation:
When it comes to treating addiction as well as some other medical ailments, detoxification is the first step in treatment. The body needs to shed the drugs in the system and the effects these drugs bring along with them as well.
Detoxification alone will not lead to lasting changes being made so option A is wrong. Detoxification is always needed for a successful treatment so option C is wrong. Option D is wrong as well because detoxification occurs within a formal treatment setting s well.

when a surgeon is operating on a bone, great care is taken to preserve the periosteum. why is it important to bone healing to take care of this delicate structure
Answer with Explanation:
It is important to take good care of "periosteum" when operating a bone because this membrane is very thin and it consists of the "osteoblast cells," which can be found in the inner layer. These cells aid in the recovery and repair of fractures in bone. This is the reason why even after falling from the tree and sustaining a fracture, a child has the ability to recover his bone injury in time. However, it takes a little longer for the bone to regenerate when it comes to older people. On the other hand, its outer layer is responsible for the blood supply in the bones.

No, a person cannot be exposed to HIV by hugging or shaking hands with an infected person because none of the bodily fluids that carry the virus are on the surface of the skin.
HIV:HIV, meaning human immunodeficiency virus, is a virus that causes a disease called acquired immunodeficiency syndrome (AIDS).
HIV, like every other virus requires the living host to be functional and replicate. However, it is only carried in the fluid (blood) of the host.
This means that HIV cannot be contracted superficially without fluid contact.

Explanation:
The minimum amount of stimuli that can be detected by one of your senses, such as faintest of smells humans can detect is called the
a) extrasensory perception
b) sensory receptor
c) adaptation syndrome
d) absolute threshold
Answer:
The minimum amount of stimuli that can be perceived by the senses is called the absolute threshold (option d).
Explanation:
Absolute threshold implies the capacity of a sensory receptor to perceive very small stimuli and marks the beginning of the perception of a specific sense. This means that any stimulus whose intensity is less than the absolute threshold will not be perceived.
The capacity to perceive stimuli is individual, and for each person the absolute threshold is different, which is why there are people with a better sense of smell or a greater capacity to differentiate flavors. Repeated stimuli can cause the absolute threshold to increase, decreasing the capacity to perceive very small stimuli.
the other options are not correct because:
a. Extrasensory perception is an unproven phenomenon that involves perceiving stimuli by senses other than the five already known.
b. A sensory receptor is a structure capable of detecting stimuli and converting them into nerve impulses.
c. The adaptation syndrome is more linked to stress and the presence of stressors.
