Answer:
a. informed consent
Explanation:
Informed Consent (IC) is the patient's authorization obtained by the professional to perform an undisputed medical procedure. It is an indispensable condition of the contemporary doctor-patient relationship. It is a voluntary decision, verbal or written, carried out by an autonomous and capable person, taken after an informative process, to accept a specific treatment aware of its risks, benefits and possible consequences.
The researcher who proposed free medical care to the Smith couple's children violated informed consent because informed consent must be voluntary for the patient. In this case, the participation of Smith's children in the research is not voluntary, as patients were offered medical treatment in exchange for their participation in the research. In addition, informed consent must be given by the volunteer, not his parents, and the volunteer must be an autonomous person who can make decisions for himself, so we can conclude that the volunteer cannot be a child.
Answer:
Two tests you can do at home to test your cardiovascular fitness and respiratory systems are Lunges and Pushups.
The answer should be atria. (singlular: atrium)
Since there's 4 heart chambers in human heart, there is the left atrium and the right atrium.
The common function of atria is to receive blood transported from the veins. Which will then be pumped into arteries after leaving the atrium and the ventricle, which is the lower chamber of heart. The right atrium receives blood from the vena cava, which is transported from all the body parts, except lungs, while the left atrium receives blood from the pulmonary veins, which transport blood from the lungs.
Below the atria, there's also valves. When they're open, they allow blood to leave the atria, and towards the ventricle. They tend to open when the blood has too much weight which will push them open.
Usually, atria is smaller than ventricle, as they're not the location for the muscles to pump the blood away from the heart.
