Chromosomes are NOT visibly divided into chromatids (think âchromosome kidsâ) until metaphase ;3. Twisting and crossing over are NOT to be shown here. E. PROCEDURE: Do all the following from memory and understanding so far; think of each stage as a frame in amovie film of the process:1.
Distant heart sounds. Introduction. Doctors with a stethoscope heart auscultation if the first heart sound and the second heart sound are weak, heavy cloud, blurred distant sense of those who, for the heart sound far away. Patients are often forced to take semi-recumbent, sitting forward, if supine is the heart sounds more distant. Tuberculous, cancerous, suppurative, rheumatic and some connective tissue diseases caused by pericardial effusion may cause heart sounds distant. Heart sounds far from some patients with chest pain, shortness of breath, difficulty breathing, shallow breathing, cyanosis, poor pulse pressure, congestive splenomegaly and other symptoms.
The Second Heart sound (S2) Dub is caused by blood slamming shut of the semilunar valves (Aortic and Pulmonic). The left side (Aortic valve) is the loud one here because the left side of the heart is the high pressure side. Just like S1, these sounds can be split. Pro Tip: In Tachycardic (fast heart rate) patients, the two sounds LUB DUB sound the same sometimes and its hard to distinguish them.
