Answer:
The correct answer will be option B.
Explanation:
Blood pressure represents the pressure of the blood in the major arteries of the body.
This blood pressure increases in the arteries when the ventricle contracts to push the blood to the major artery by a mechanism called ventricular systole. This increased blood pressure number is known as systolic blood pressure which is usually 180 mm of Hg.
The blood pressure decrease in the artery due to ventricular diastole during which ventricles relaxes. This lower number of blood pressure is known as diastolic blood pressure which is 80 mm of Hg.
Thus, option B is the correct answer.
Answer:
The correct answer is D.
Explanation:
Papillary muscles, attached via chordae tendineae, help to close the valves and prevent regurgitation.
Pectinate muscles are parallel ridges in the walls of the atrium of the heart, mainly in right atrium. They can stretch during adverse loading conditions, to <em>help the right atrium to dilate without much wall stres</em>s.
Answer:
Deoxygenated blood enters the right atrium from the superior and inferior vena cava > The blood flows through the tricuspid valve into the right ventricle >From the right ventricle, the blood flows through the pulmonary valve into the pulmonary artery > The right and left pulmonary arteries carry deoxygenated blood to the right and left lungs for gas exchange > The blood releases carbon dioxide as waste and picks up a fresh supply of oxygen > The oxygenated blood flows through the pulmonary veins from the lungs into the left atrium > From the left atrium, the blood flows through the bicuspid, or mitral valve into the left ventricle > Left ventricular contraction forces blood through the aortic valve into the aorta for distribution to the systemic circulation
Explanation:
An antidyskinetic drug is amantadine. It is used to treat Parkinson's disease and related symptoms, such as dyskinesia (also known as "paralysis agitans" or "shaking palsy") (sudden uncontrolled movements).
<h3>
What Amantadine used for?</h3>
- As the disease symptoms lessen, this medication enables more typical motions of the body by enhancing muscular control and lowering stiffness.
- The stiffness and shakiness brought on by some medications used to treat nervous, mental, and emotional problems is another issue that amantadine is used to address.
- Amantadine is also an antiviral medicine. It is utilized to either cure or prevent certain influenza (flu) illnesses (type A). It can be given either on its own or along with a flu vaccine.
- Colds, various varieties of the flu, and other viral diseases are not treatable with amantadine.
- Only a prescription from your doctor is required to purchase this medication.
