From парциального pressure of physically dissolved carbonic gas process of linkage СО2 by blood depends. Carbonic acid arrives in эритроцит where there is an enzyme карбоангидраза which can increase speed of formation of coal acid in 10 000 times. Having passed through эритроцит, coal acid turns to bicarbonate and is transferred to lungs. It arrives from a gleam канальца in cages проксимального канальца by means of a special carrier which should attach necessarily ion Na +. Moving of this complex in a cage is carried out passively on electrochemical and concentration gradients for ions Na +. Low concentration натрияв to a cage, creating a gradient of its concentration between the external and endocellular environment, is provided with work pump sodium-kalievogo базальной membranes. In a cage this complex breaks up to compound components. In nephritic эпителия high concentration of glucose is created, therefore further on a gradient of concentration glucose passes in интерстициальную a fabric. This process is carried out with participation of a carrier at the expense of the facilitated diffusion. Further glucose leaves in a blood-groove. In norm at usual concentration of glucose in blood and, accordingly, in primary urine all glucose реабсорбируется. At surplus of glucose in blood so, in primary urine there can be a maximum loading канальцевых transport systems, i.e. all molecules-carriers. In this case glucose cannot реабсорбироваться any more and will appear in final urine (глюкозурия). This situation is characterised by concept «maximum канальцевый transport» (Тм). To size maximum канальцевого transport there corresponds old concept «a nephritic threshold of deducing». For glucose this size makes 10 mmol/l. Wandering nerves raise motor activity of a stomach, sympathetic - oppress. The great value in regulation of a motility of a stomach has внутриорганный department of vegetative nervous system (ауэрбаховское a texture) at the expense of local peripheral reflexes. Exciting action on сократительную activity of smooth muscles of a stomach insulin, potassium ions possess гастрин, гистамин, серотонин, мотилин. Braking of a motility of a stomach cause энтерогастрон, adrenaline, норадреналин, секретин, глюкагон, HTSK-PZ, ЖИП, ВИП, бульбогастрон. The mechanical irritation of intestines food substances leads to reflex braking of impellent activity of a stomach (энтерогастральный a reflex). This reflex is especially expressed at receipt in a duodenal gut of fat and hydrochloric acid. estimation of functions of the higher departments of is biologically more significant for an
One of the perks of a small business is that it’s….wait for it….small. In theory, this means less red tape, more efficient decision-making, more flexibility, and so on. But it also means a smaller team of employees, so it’s common for small business owners to end up doing everything themselves. Is doing everything yourself the best idea? No, no it is not.
When you run a small business, work can easily take over every aspect of life. Resist the temptation to do everything yourself. Without even realizing it, many small business owners find themselves buried under a pile of assignments as one person fills the role of editor, marketer, consultant, office manager, HR, PR, accountant and receptionist. Doing everything yourself is a quick road to burnout. The good news? Delegating is an easy way to free up time for you to spend where it counts.
Delegation is not a dirty word
Take a look at the way you spend your time. What parts of your workday include tasks you resent, or find draining? What would you do with the extra time if you didn’t have to do those things? Examine what tasks you’re currently doing that someone else could do for you. For example, if doing all your company’s packing and shipping takes up a chunk of your day, consider outsourcing it. Many small business owners want to delegate, but think it will be too expensive to hire it out. This may not be true. Remember that doing everything yourself isn’t free. It costs your time and your energy, and if you can spend your time and energy elsewhere with greater returns, it’s worth the cost of delegating. You can also look at bartering, offering to swap services with someone who offers the service you need.
If delegating a task gives you more time to do something more efficient, it’s certainly worth the price of hiring it out. If you insist on doing it all, it’ll prevent you from having it all.
