68. Which structures produce the digestive enzymes that act in the small intestine?
|
The pancreas and liver produce the enzymes and the gallbladder delivers them when needed.
|
|
|
69. What are the functions of the large intestine?
|
The functions of the large intestine are to absorb water and concentrate and store feces for removal from the body.
|
|
|
70. List the components of the urinary system and their functions.
|
a. Kidneys – filters blood and forms urine
b. Ureters – transport urine to the bladder c. Urinary bladder – stores urine d. Urethra – carries urine away from the body |
|
|
71. Describe the ways in which kidneys maintain homeostasis.
|
A kidney removes nitrogenous waste, ions and unneeded molecules from the blood and maintains the water balance, volume, pH and pressure of the blood.
|
|
|
72. Explain glomerular filtration, tubular reabsorption, and tubular secretion by nephrons. Where in the nephron does each process occur
|
a. Filtration – movement of a protein-free solution of fluid and solutes from the glomerulus into the capsule that occurs in the glomerulus
b. Reabsorption – return of most of the fluid and solutes into the peritubular capillaries from the proximal tubule c. Secretion – the addition of certain solutes from the peritubular capillaries into the tubule. |
|
|
73. Describe the process and mechanisms involved in urination.
|
The bladder is prevented from emptying by internal and external urinary sphincters. When these sphincters release, urine flows down the urethra to the external environment.

74. Name the male and female gonads. What are the functions of these organs?
|
Female gonads are the ovaries and male gonads are testes. They both function to produce gametes (eggs and sperm)
|
|
|
75. How is the temperature maintained in the testes? Why is temperature control important?
|
Temperature maintenance depends on smooth muscle in the scrotum contracting to move the testes closer to the body for warmth or relaxing so the testes are farther away from the body. Sperm develop better in the testes at few degrees lower than body temperature.
|
|
|
76. Trace the path of sperm from their site of production to their release from the body, naming each tube the sperm pass through.
|
Seminiferous tubules Epididymis Vas deferens Urethra
