Various aspects of the respiratory system and the digestive system. It includes questions and answers about the functions, structures, and processes of these two important body systems. The respiratory system section covers topics such as gas exchange, the role of the nasal conchae, the respiratory center in the nervous system, and the mechanics of inhalation and exhalation. The digestive system section explores the passage of food through the digestive tract, the ph changes along the tract, and the absorption of nutrients. The document also includes a crossword puzzle and a concept map related to the respiratory and digestive systems, as well as a discussion about the urinary system and the male and female reproductive systems. Overall, this document provides a comprehensive overview of these key physiological systems and could be useful for students studying biology, anatomy, or related subjects.

Ureters water/fluid nephrons acid-base semen
Exterior incontinence 20 4 micturition

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.
