      +Ntethelelo Sibiya There are several factors in learning anatomy. One plan I found that successfully combines these is the Anatomy Blueprint Pro (check it out on google) definately the most useful course i've heard of. look at this interesting resource.

    Summery of video explained by Sir : notes🥰
    1)Deoxygenated blood from body tissue go to right atrium and then from right atrium to right ventricals and then go to lungs for oxygenation
    2) blood cam to heart from lungs in left atrium and then move to left ventricle and then go to body tissue.
    3) heart cell myocytes and special kind of striated cells and if one cell contact all cell contact together and make unilateral blood flow
    4) membrane potential is negative inside in rest and becomes more positive when it have to contract
    5) when is at rest pottaciam is more inside and calcium and sodium is more outside
    6) channels open and potential changes.

  • @TheSaintemplar64
    @TheSaintemplar64 7 лет назад

    Excellent - just a note on action potentials. You must clarify that Ca+ move because of N+ movement..N+ wants to move down its gradient and K+ likewise when therefore N+ moves across the membrane it causes Ca+ to open and Ca+ moves across the protein channels which is are action potential and I always say the cell becomes less negative moving away from its resting potential rather than becoming more positive because its nearly always in a negative state.

    At first glance the study of human anatomy seems to bo complex and overwhelming. It's true that it's complex and your studies will not alter that. As for it being overwhelming, that can be eleviated if you take your study one step at a time. I discovered an article on Sebs Study Crammer extremely helpful for this.

    • @DDevilisHH
      @DDevilisHH 7 лет назад +8

      I know what it's like to be impatient to get out there and be a doctor, but unfortunately it takes that long because there's a lot to learn and a huge responsibility! In order to be a cardiologist you have to study the whole human body so that you can understand what happens to the rest of it when the heart fails. You need to go medical school, and then after med school do your country's internship and residency program under guidance of senior cardiologists, so you're certain you know what you're doing once you have patients of your own. While you can't make medical school take fewer years, try to study what interests you in your spare time to keep up the motivation! That will make it easier when you get to med school as well.
      It might take you ten years, but those ten years will pass anyway, even if you skip out on med school just because of the time it takes. You might as well do something you love during all that time! Good luck!

    Good video has pulmonary Artery and the pulmonary vein backwards though. O2 poor blood is always in veins and o2 rich blood is always in Arteries. So pulmonary vein brings blood to right atria. Pulmonary artery brings blood to left atrium from lungs.

    • @patrickhenderson2538
      @patrickhenderson2538 6 лет назад

      His video is correct. Arteries always carry blood away from the heart. So, pulmonary arteries carry oxygen depleted blood away from the heart & to the lungs. Veins always carry blood towards the heart. So, pulmonary veins carry oxygen rich blood towards the heart.

    Can the heart be slowed by using my mind through concentration?

    • @ccmmoopp45
      @ccmmoopp45 7 лет назад +3

      there is a nervous regulation of the heart that depends on your state of mind (relaxed: lower heart rate ; or stressed: higher heart rate) it is the sympathetic and parasympathetic system

    • @jr1019
      @jr1019 7 лет назад

      Is it harmful? I recently had an atrial fibrillation incident and the cardiologist laughed at me when I suggested I induced it with my mind. I feel like I have concentrated on the area of the heart for so long that I feel like I can manipulate my heartbeat. The cardio doctor said it is impossible and that everything is chemical, biological, and physiological. I think I disagree. However, he pointed at all the certificates, accomplishments, and accolades that were on the wall that he had received from all his training and asked me "who knows more?" So as usual he took out a pen and pad to write a prescription. Why do they dismiss the power of the mind?

    • @ccmmoopp45
      @ccmmoopp45 7 лет назад +1

      calinative imperial well first you might do the basic heart imagery (echo doppler...) then if there is nothing I think that the issue is in the neural system so a neurologist may find a relation between your stress and heart dysfunction

    how would you differentiate between absolute and relative refractory period of myocardial action potential?

    • @davidvucen5098
      @davidvucen5098 8 лет назад +1

      The absolute refractory period (ARP) of a miocardiocyte last from the beggining of the extremely fast depolarisation (from phase 0) and last almost through the whole repolarisation period (phase 3). So it last during phases O, 1, 2 and the biggest part of phase 3. The relative refractory period (RRP) last during the ending part of the repolarisation (phase 3). After that comes phase 4. In this phase ions are getting back to their normal positions and the RMP (rest membrane potential) is set up again and the cell is now ready for a new excitation. Also, during ARP the cell can't be excitated. During the RRP it can, but harder. If some mistake in nodal cells is made and an information is sent during the RRP, and the cell produces an action potential, really serious rhytmic problems can occour. Hope it helped, sorry for my bad English. :)
