Q

What is the liver?

organ that is part of the excretory system

18
Q

What is the loop of henle?

A

the u shaped section of the kidney tubule; plays a major role in the reabsorption of water and salts from the filtrate

19
Q

What is the lung?

A

one of a pair of organs for gas exchange occupying the chest cavity

20
Q

What is a nephron?

A

the functional unit of the kidney

21
Q

what is peritoneal dialysis?

A

dialysis occurring inside the body using the peritoneum as the membrane across which wastes can be removed

22
Q

What is the peritoneum?

A

the membrane that lines the inside of the abdominal cavity

23
Q

What is the peritubular capillaries?

A

the capillaries in the kidney that surround the convoluted tubules of the nephron, the loop of henle and the collecting duct

24
Q

What is the proximal convoluted tubule?

A

the first set of convolutions of the kidney tubule, located between the glomerular capsule and the loop of henle

25
Q

What is the renal artery?

A

the blood vessel that transports blood into the kidney

26
Q

What is the renal capsule?

A

a tough fibrous layer surrounding the kidney

27
Q

What is the renal column?

A

an extension of the renal cortex that divides the renal medulla into renal pyramids

28
Q

What is the renal corpuscle?

A

the filtration structure of the nephron composed of the glomerulus and glomerular capsule

29
Q

What is the renal cortex?

A

the outer part of the kidney

30
Q

What is the renal hilum?

A

a depression in the kidney where blood vessels and the ureter enter

31
Q

What is the renal medulla?

A

the inner part of the kidney

32
Q

What is the renal pelvis?

A

the cavity of the kidney that collects urine before it passes to the ureter

33
Q

What is the pyramid?

A

a section of the renal medulla

34
Q

What is the renal tubule?

A

the kidney tubule; it leads away from the glomerular capsule and empties into a collecting duct

35
Q

What is the renal vein?

A

the blood vessel transporting blood away from the kidney

36
Q

What is selective reabsorption?

A

the reabsorption of some substances and not others in the renal tubules

37
Q

what are sweat glands?

A

tubular structures in the skin that produce sweat

38
Q

what is tubular secretion?

A

the process whereby ions and drugs are secreted from the blood into the kidney tubule

39
Q

What is the ureter?

A

the tube that leaves each kidney and drains into the urinary bladder

40
Q

What is uric acid?

A

a breakdown product of the metabolism of purines such as the bases adenine and guanine found in DNA and RNA

41
Q

What is the urinary system?

A

the system composed of the kidneys, ureters, bladder and urethra that is responsible for the excretion of wastes, the regulation of blood volume, pressure and pH as well as the concentration of chemicals

42
Q

What is urine?

A

the fluid produced by the kidneys that contains wastes and excess materials
