Heart sounds are caused when the valves close during a normal cardiac cycle. Murmurs can be caused by turbulent blood flow through a valve that is either constricted (stenotic) or leaking (regurgitant). Mr. G's mitral valve leaks, letting blood flow through when it should be closed. How could his valve defect have caused the systolic murmur?

Answers

Answer 1
Answer:

Mitral regurgitation is a leakage of blood that flows backward via the mitral valve during contraction of the left ventricle which results in systolic murmur.

Explanation:

Mitral valve is seen between the left atrium and left ventricle,it prevents the back flow of blood during left ventricular contraction. In case of mitral valve regurgitation or stenosis condition it results in back flow of blood to left atrium it further results in increased blood pressure in left atrium and fluid buildup in lungs and leads to systolic murmur. During cardiac cycle systole occurs when heart contracts and diastole occurs when heart relaxes.

Answer 2
Answer:

Final answer:

A systolic murmur, like in Mr. G's case, is caused by a mitral valve defect. The valve leaks during systole, causing abnormal blood flow, which in turn leads to the creation of the murmur.

Explanation:

Mr. G's mitral valve defect could have caused a systolic murmur due to the leaking of the valve. In a healthy heart, the mitral valve should close during the process of systole to prevent the backflow of blood. However, in Mr. G's case, the mitral valve leaks, leading to an abnormal flow of blood. This irregular flow creates a noise known as a murmur. This is specifically termed a systolic murmur because it happens during systole - the phase of the heart beat when the heart muscle contracts and pumps blood out of the heart.

Which organ performs the given function? The roof of the mouth separates the oral cavity from the nasal cavity. The is flexible and closes off the nasal cavity when you swallow.

Answers

Soft palate


The soft palate is composed of muscle and connective tissue, which give it both mobility and support. This palate is very flexible. When elevated for swallowing and sucking, it completely blocks and separates the nasal cavity and nasal portion of the pharynx from the mouth and the oral part of the pharynx.

Final answer:

The palate separates the oral cavity from the nasal cavity, and comprises of two parts: the hard palate at the front and the soft palate at the back. The soft palate is flexible and closes off the nasal passage when we swallow.

Explanation:

The organ that separates the oral cavity from the nasal cavity is the palate. The palate comprises of two sections: the hard palate at the front, made of bone and the flexible soft palate at the back that closes off the nasal cavity when we swallow.

Essentially, the palate plays a significant role in our ability to eat and speak correctly. When we swallow, the soft part of the palate seals off the nasal passages, ensuring food and liquid pass from the oral cavity to the esophagus avoiding the nasal cavity.
