The initial filtration step in the glomerulus of the mammalian kidney occurs primarily by

The correct answer is- passive flow due to pressure difference

Explanation:

The movement of water and different solute from the blood to the renal tubules or the renal corpuscles is called filtration. This filtration occurs due to the difference in the blood pressure in glomerular capillaries.

As the blood pressure increases in the glomerulus, the hydrostatic pressure also rises in the glomerulus which increases the filtration rate in glomerulus so more blood gets into glomerulus due to this pressure.  

Therefore as the blood pressure increase in the glomerulus, the filtration rate also increases. So the initial filtration step in the glomerulus occurs primarily by passive flow due to pressure difference.

answer

ben’s food poisoning was caused by cross-contamination

explanation

cross-contamination in food occurs when harmful bacteria is transferred to food from other foods, utensils or cutting boards. it happens often when handling raw meat , sea foods and poultry. in this case, because ben did not wash hands before and after handing the poultry, chances that bacteria transfer   from the poultry to the vegetable are high.

answer;

no:

a diagnostic thoracoscopy is always included in the surgical vats

explanation;

vats means video assisted thoracic surgery.

thoracoscopy is an endoscopical procedure completed on the lungs to visualize pleura, lungs and mediastinum using an endoscope

one thing to note is that a surgical thoracoscopy always includes a diagnostic thoracoscopy.

the diagnostic thoracoscopy codes are differentiated by the site and type of procedure performed.
