Answer: D. Contractility of the heart muscle refers to the force of contraction that this muscle can exert.
Explanation:
The myocardial contractility is ability of the heart muscles to contract. This is achieved by the forces which develop between the contracting muscles caused by the filaments of actin and myosin.
The degree of binding of the muscle filaments dependents upon the calcium ion concentration. These actions are controlled in vivo by the sympathetic nervous system. It is driven by the release of the catecholamine, which is a process which determines the calcium ion concentration inside the cytosol of the muscles of the heart.
Answer:
True
Explanation:
<u>Rotational and linear motions are analogous to each other.</u>
<u>The inertia of a body in a linear motion is its mass.</u> This can be seen from Newton's second law of thermodynamics:
F = ma
The larger the value of the force, the larger the inertia is (m) and the slower it accelerates.
<u>The inertia of a body in a rotational body is it moment of inertia (I).</u> Both I and m are same but I depends on both the shape and mass of the rotating body.
For example, The inertia of a solid disk with mass M and radius R is:

Hence, the statement is true.
The urine volume would enhance if ADH was not added to the collecting duct. This is because the ADH works on the collecting ducts where the increase permeability for water is improved, so less water is perspired into the urine, so urine evolves more concentrated.
<h3>What happens to urine volume when ADH advances?</h3>
- ADH improves the permeability to water of the distal serpentine tubule and collecting duct, which is normally impervious to water. This effect causes heightened water reabsorption and retention and reduces the volume of urine produced comparable to its ion content.
- In SIADH, the body is unable to subdue the secretion of ADH, conducting to insufficient water excretion and reduced urine output. Normally, when water is ingested, serum tonicity and osmolality reduction, and ADH are quelled, resulting in an output of dilute (less concentrated) urine.
- A hormone that allows blood vessels narrow and helps the kidneys control the portion of water and salt in the body. This enables the control of blood pressure and the quantity of urine that is made. Antidiuretic hormone is made by a portion of the brain called the hypothalamus and is perspired into the blood by the pituitary gland.
