Kidney Flashcards

1567197679	Nephron	functional unit of the kidney, selective filter element comprising of a renal tubule and blood vessels, regulate blood composition and pH	0
1567197680	Cortex	Outer part of the kidney	1
1567197681	Medulla	middle part of the kidney	2
1567197682	renal pelvis	inner part of the kidney, urine collects here	3
1567197683	ureter	urine flows out of kidney via ureter to bladder	4
1567197684	bladder	collects urine	5
1567197685	glomerulus	network of capillaries that performs the first step of filtering blood	6
1567197686	Bowman's capsule (also called renal capsule)	first part of the nephron, surrounds the glomerulus, receives the ultrafiltrate from glomerulus	7
1567197687	nephron tubules	Filtrate flows from Bowman's capsule to renal pelvis through nephron tubules. Here the filtrate is modified by active secretion of for example toxins into the filtrate and reabsorption of useful substances back into the blood. The final product is called urine.	8
1567197688	ADH	hormone, promotes reabsorption of water, as a result urine contains less water and is more concentrated	9
1567199373	draw and label a kidney with the following terms: Cortex, Medulla, Pelvis, renal artery, renal vein, ureter, nephron		10
1567207691	secretion	Unwanted substances like poison can be actively secreted into the blood stream.	11
1567207692	reabsorption	Useful substances like glucose, minerals, amino acids and some water are taken back in (reabsorbed into) the blood stream.	12
1567207693	excretion	the process by which waste products of metabolism and other non-useful materials are eliminated from an organism. Note the difference between egestion and excretion: Egestion (also called defecation) is the passing out of substances that can not be digested and used by the body in form of feaces.	13
