20
Q

Urinary System Helps Maintain

A

Salt/Water Balance
Blood Pressure
Acid/Base Balance

21
Q

Nephron Structure

A

BowMan’S Capsule, Glomerulus, Renal Proximal And Distal Tubules, Collecting Tubule

22
Q

Renal Arteries Renal Veins

A

Blood from the systemic circuit flows into each kidney through the renal arteries, leaves via the renal veins

23
Q

Renal Pelvis

A

Renal Pelvis is central/inner cavities where newly formed urine drains. Ureters connect to them

24
Q

More About Nephronss

A

Nephrons are, which carry out filtration, consist of interwoven capillary beds and convoluted tubules, close enough that active transport and diffusion can occur

25
Q

Glomerulus

A

Glomerulus is a brain-like bundle of capillaries It is surrounded by Bowman’s capsule (a hollow capsule) This is like a baseball in a mitt

26
Q

BowMan’S Capsule

A

Surrounds Glomerulus It is surrounded by Bowman’s capsule (a hollow capsule) This is like a baseball in a mitt

27
Q

Proximal Convoluted Tubule

A

H24 and other chemicals in the blood leave (via pressure/diffusion) the capillary and enter the BowMan’S capsule, flowing into the proximal convoluted tubule

28
Q

Distal Convoluted Tubule

A

The same capillaries extend to surround the tubule, allowing molecules to be brought back into the blood, all the way until the distal convoluted tubule; remaining is urine

29
Q

Collecting Tubule

A

Many collecting tubules carry urine to the renal pelvis

30
Q

How Many Nephrons Are There Per Kidney

A

Many collecting tubules carry urine to the renal pelvis

31
Q

How It Works

A

Glomerular filtration occurs when blood enters the glomerulus and the afferent arteriole. Blood in the glomerulus has two portions: the filterable components, and the non filterable components. Due to glomerul blood pressure, water and small molecules are pushed from the the glomeruli to the inside the Bowman’s capsule. This is a filtration process because large molecules and formed elements are able to pass through the capillary wall.
If the composition of urine was the same as that of glomerular filtrate, we would constantly be losing water, salts, and nutrients. This doesn’t happen because the composition of the original filtrate is altered significantly as fluid passes through the remainder of the tubule. As said earlier, they are reabsorbed into the blood as they pass through the proximal convoluted tubule

32
Q

Function Of Ureters

A

The Ureters (muscular tubes; use peristalsis) carry newly formed urine from the kidneys to the bladder

33
Q

Function Of Bladder

A

The bladder (a pouch of smooth muscle tissue) has 3 openings; two entry points and urethral opening

34
Q

Proximal

A

Situated nearer to the center of the body or the point of attachment

35
Q

Distal

A

Situated away from the center of the body or from the point of attachment

36
Q

Superior

A

Further above or out; higher in position

37
Q

Inferior

A

Low or lower in position
