Exchange of calcium between bone and ext...

Exchange of calcium between bone and extracellular fluid takes place under the influence of certain hormones
(a) What will happen if more of `Ca^(2+)` is in extracellular fluid?
(b) What will happen if very less amount of `Ca^(2+)` is in the extracellular fluid?

Text Solution

Verified by Experts

(a) High `Ca^(++)` level in extracellular fluid stimulates parafollicular cells of thyroid gland to secrete Thyrocalcitonin hormone (TCT) which activates the obteoblasts which deposit extra calium in the bones .
(b) Low `Ca^(++)` level in exteracellular fluid stimulates parthyroid glands to secrete Parathormone (PTH) which activates osteoblasts which separate calium frome the bones to regulate `Ca^(++)` Level.

Viscosity is the property of fluid by virtue of which fluid offers resistance to deformation under the influence of a tangential force. In the given figure as the the plate moves the fluid particle at the surface moves from position 1 to 2 and so on, but particles at the bottom boundry remain stationary. if the gap between palte and bottom boundary is small, fluid particles in between plate and bottom moves with velocities as shown by linear velocity distribution curve otherwise the velocity distribution may be parabolic. As per Newton's law of viscity the tangential force is related to time rate of deformation - (F)/(A) alpha (d' theta)/(dt) but y = (d' theta)/(dt) = u, (d' theta)/(dt) = (u)/(y) then F = eta A(u)/(y), eta = coefficient of viscosity for non-linear velocity distribution - F = eta A(du)/(dy) where (u)/(y) or (du)/(dy) is known as velocity gradiant. The velocity gradient just below the plate, in above problem is equal to - (per second)
