Answer:
Principal Cell
Explanation:
The main sodium ion absorption cells are the principal cell. These cells are also the site for the action of aldosterone.
Blood flows in layers within the lumen of blood vessels, with the layers in the middle of the lumen flowing fastest. this is known as laminar flow.
<h3>What is Laminar flow ?</h3>
The majority of the circulatory system typically operates with laminar flow. It is characterised by parallel motion of concentric layers of blood along a blood vessel's length. The middle of the vessel has the highest velocity (Vmax).
- Laminar flow is when the flow is fastest in the centre of the blood vessel and slowest along the wall of the vessel, where there is greater friction (where there is less friction).
- Blood flow in the body is typically laminar. Laminar flow can, however, be disturbed and turn turbulent under situations of high flow, particularly in the ascending aorta. When this happens, blood does not flow in adjacent layers in a straight line or gradually; instead, it flows chaotically.
