Pangea was assembled in the late permian and broke up in the late triassic
Belgrade is in Central European Time (CET=UTC+1) from late October until late March and Central European Summer Time (CEST=UTC+2) from late March until late October.
In late prophase, the nuclear envelope breaks down. This allows the chromosomes to be fully condensed and ready for division during metaphase.
The synaptonemal complex disappears during the diplotene stage of meiosis. This dissolution marks the end of the physical connection between homologous chromosomes, allowing them to separate and continue with the process of meiosis.
During the late Cenozoic era, which began around 66 million years ago, mammals became dominant on Earth. This era saw the evolution and diversification of mammals into various forms and sizes, including early primates, whales, and elephants. Additionally, birds also thrived during this time period.
It decreases.
Mid-to-late diastole, ventricular systole and early diastole
do not require an external stimulus to reach threshold, while other cardiac cells do.
The dicrotic notch occurs during the late systole phase of the cardiac cycle, specifically when the aortic valve closes, causing a temporary rise in aortic pressure due to the recoil of blood in the aorta. This event marks the end of ejection and the beginning of diastole.
In late diastole (relaxation phase), the semilunar (pocket) valves close, due to decreasing arterial pressure, to prevent blood flowing back into the ventricles. These stay closed during atrial systole. (But open again during ventricular systole.)Then, as the ventricles contract during ventricular systole, the bicuspid and tricuspid valves close to prevent blood from flowing back to the atria.So, it really depends on which phase of the contraction we are looking at.(Ed: format)
During the late fall early winter months, deer velvet grows. At the base of each antler is a ring, and that ring controls whether blood is allowed to flow into the antlers. This blood flow determines whether the antlers grow or not. The blood flows into the antler and supplies vitamins and minerals needed for the deer to grow bigger antlers, and since the blood needs a cover, velvet is formed around the blood vessels. When the antlers receive enough vitamins and minerals, the ring at the base of the antler cuts off the blood flow, causing the velvet to dry out, shrivel up, and fall off.
Old blood, which is normal and very common.
Yes, coffee can slow down and lessen your menstrual flow - although not by that much, certainly it'snot the most effective method of reducing flow. Coffee is a vasoconstrictor, which basically means that it causes the blood vessels in the uterus to constrict which limits blood loss.
There are many phases of the cardiac cycle- in total five stages occur. phase 1) - Isovolumetric ventricular contraction In response to ventricular depolarization, tension in the ventricles increases. The rise in pressure within the ventricles leads closure of the mitral and tricuspid valves. The pulmonic and aortic valves stay closes during the entire phase. 2) ventricular ejection: When ventricular pressure exceeds aortic and pulmonary arterial pressure 80MMHG- the aortic and pulmonic valves open and the ventricles eject 70% of the blood. 3) Isovolumetric relaxation: when ventricular pressure falls below pressure in the aorta and pulmonary artery, the aortic and pulmonic valves close. All valves are closed during this phase. Atrial diastole occurs as blood fills the atria.4) ventricular filling: atrial pressure exceeds ventricular pressure which causes the mitral and tricuspid valves to open. Blood then flows passively into the ventricles. About 70% of ventricular filling takes place during this phase. 5) atrial systole: known as the atrial kick, atrial systole coinciding with late ventricular diastole supplies the ventricles with the remaining blood for each heart beat. Diastole: This occurs in-between heartbeats to allow blood to refill the heartSystole: when the atria and ventricles contact For more information e-mail me: Elliottcollins@hotmail.co.uk I also have a VERY helpfull link belowHow_heart_works
S3 heart sound is heard after the S2 heart sound (the sound made by the closure of the aortic and pulmonary valves following systole). It therefore happens in early-mid diastole, when the ventricles are beginning to fill. The sound is caused by a vibration of the ventricles as they encounter blood flow. Though an S3 may be normal in children and young adults, in other populations it may indicate a pathology in 1) a higher than usual amount of blood returning to the ventricle (such as in hypervolemic states), or 2) a stiff ventricle that's more prone to reverberation (e.g. remodeling secondary to heart failure) . S4 is also due to a vibration in the ventricle wall but occurs later in diastole, when contraction of the atrium forces the final amount of blood into the ventricles. The vibration occurs because the ventricle is too full to contain the additional blood. This can occur in pathologic states such as ventricular hypertrophy.
You are probably ovulating (releasing an egg). Many women get discharge mixed with blood during ovulation. It could just be old blood though that is left over from your period and it is coming out with discharge
Sleeping late at night without much stress or depression is not bad for high blood pressure.
