Complete the following questions:
1. Do the following factors generally increase [indicate ] or decrease [indicate ¯] the respiratory rate and
depth?
increase in blood CO 2
: increase in blood pH:
decrease in blood O 2
: decrease in blood pH:

Complete the following discussion about the urinary system, using the words in the word bank below.
Ureters water/fluid nephrons acid-base semen
Exterior incontinence 20 4 micturition
Peristalsis external urethral urinary bladder nitrogenous
The kidney is referred to as an excretory organ because it
excretes 1 wastes. It is also a major homeostatic organ because
it maintains the electrolyte,
2 , and
3 balance of the blood.
Urine is continuously formed by the structural and functional
units of the kidneys, the 4 , and is routed down the 5 by the
mechanism of
6 to a storage organ called the
7
. Eventually,
the urine is conducted to the body 8 by the urethra. In the
male, the urethra is 9 centimeters long and transports both
urine and
10
. The female urethra is
11 centimeters long and
transports only urine.
Voiding or emptying the bladder is called 12. Voiding
has both voluntary and involuntary components. The voluntary
sphincter is the 13 sphincter, composed of skeletal muscle.
An inability to control this sphincter is referred to as 14.
Answer the following questions.
- What tissue lines the urinary bladder?
- What hormone regulates the formation and concentration of urine?
- Where do the following processes predominantly occur in the urinary system:
a. Filtration
b. Reabsorption
c. Secretion
- What materials are normally found in urine?
a. ______________________________________
b. ______________________________________
c. ______________________________________

diffusion of nutrients and oxygen between maternal
and fetal blood systems
