The male urethra is enclosed by the prostate gland and the what? penis
The outer layer of the kidney tissue is called what? renal cortex
The inner layer of the kidney is called? Renal medulla
Renal pyramids and renal medulla are the same thing? True
The cavity on the medial side is called the? renal pelvis
What is located in the renal medulla? loops of henle
In calyces are part of the are part of the? renal pelvis
In the kidney the renal pelvis has a funnel shaped extension called? calyces
The renal pelvis empties urine into the? ureter
Urine is formed from? blood plasma
Two major parts of a nephron are? renal corpuscle, renal tuble
A renal corpuscle consist of? glomerulus and Bowman's capsule
a glomerulus is surrounded by Bowmans Capsule
a glomerulus is a network of? capillaries
A bowmans capsules has how many layers? Two
The Bowmans layer that is permeable layer is the? inner
The energy for renal filtration is provided by? blood pressure
What does not become part of the renal filtrate in the process of glomerular filtration? blood cells and large proteins
What may become part of filtration in the glomerular filtration? water, waste products, and small proteins
The processes of reabsorption and secretion take place in the what portion of the nephron? renal tuble
The renal tubles are surrounded by the? peritubular capillaries
What is reabsorbed by the process of active transport? glucose, amino acids, vitamins,and positive ions,
Water is reabsorbed by the process of? osmosis
Negative ions are reabsorbed by the process of? passive transports
Small proteins are reabsorbed by the process of? pinocytosis
In the proximal convoluted tuble, the surface area of the cells is increased by the presence of? microvilli
