Explanation:
End diastolic volume (EDV)
It is the amount of the blood in the left or the right ventricle at the end load .
Or the amount of the blood present in the ventricles before systole .
The factors effecting end diastolic volume is
- Increasing venous compliance increases the capacitance of the veins decreases venous return and hence end-diastolic volume.
Answer:
The correct answer would be - Epidermoid cyst
.
Explanation:
Patient explains symptom as -
vaginal growth with no pain or discharge
no fever or night sweat
In examination following symptoms found-
Healthy looking, normal blood pressure and body temperature
found 2 -3 mm yellow, round nodules on the left labia but not painful and quit firm.
Diagnosis on the basis of symptoms and examination-
Epidermoid cyst
Reason : epidermoid cysts are nodules that are small round firm found in the labia and characterized as nonpainful formed due to blocked sebaceous gland.
Thus, the correct answer is - Epidermoid cyst
.
Answer:
(A) - The volume of the blood plasma increases on overhydration and decreaes on dehydration.
(B) - Osmolality of blood increases with the dehydration and decreases with the overhydration.
Explanation:
If the levels of drinking water is increased, then the plasma becomes more dilute and the plasma volume increases because <u>the water will be reabsorbed more and which as a result reduces plasma concentration of the solutes and increases volume of plasma.</u>
Plasma osmolality measures electrolyte-water balance of the body. <u>As mentioned, above on overhydration, the plasma concentration of the solutes decraeses which also decreases osmolality. So, Osmolality of blood increases with the dehydration and decreases with the overhydration. </u>Increased osmolality in blood stimulate the secretion of antidiuretic hormone which results in the increased water reabsorption and therefore, more concentrated urine and hence blood plasma with less concentration.
Answer:
The correct answer is D.
Explanation:
Papillary muscles, attached via chordae tendineae, help to close the valves and prevent regurgitation.
Pectinate muscles are parallel ridges in the walls of the atrium of the heart, mainly in right atrium. They can stretch during adverse loading conditions, to <em>help the right atrium to dilate without much wall stres</em>s.
