Anatomy & Physiology

 

Chapter 18 - The Urinary System and Fluid Balance

Functions of the Urinary System
1. List the major functions of urinary system.

Urinary System
2. List the structures that make up the urinary system.
3. Describe the location and anatomy of the kidneys.
4. Describe the structure of the nephron and the location of the parts of the nephron in the kidney.
5. Describe the ureters, urinary bladder, and urethra.

Urine Production
6. Identify the principal factors that influence filtration pressure and explain how they affect the rate of filtrate formation.
7. Give the function of the proximal tubule, descending and ascending limbs of Henle's loop, distal tubule, and collecting duct.
8. Explain how the movement of substances across the wall of the nephron and collecting duct influences the composition of the filtrate.

Regulation of Urine Concentration and Volume
9. Explain how antidiuretic hormone, aldosterone, and atrial natriuretic hormone influence the volume and concentration of urine.

Urine Movement
10. Describe the micturition reflex.

Body Fluid Compartments
11. List the major body fluid compartments.

Regulation of Extracellular Fluid Composition
12. Describe the mechanisms by which, Na1, K1, and Ca21 are regulated in the extracellular fluid.

Regulation of Acid = Base Balance
13. Illustrate how the mechanisms that regulate the body fluid pH function by explaining how they respond to decreasing and increasing pH in the body fluids.

 

Indicators:  The students will understand that:

 

            1.         Animals have behavioral responses to internal changes and to external stimuli.

 

Examples:       Responses to external stimuli can result from interactions with the organism's own species and others, as well as environmental changes.  These responses can be innate and/or learned.

Animals often live in unpredictable environments, and so their behavior must be flexible enough to deal with uncertainty and change.

 

            2.         Most multicellular animals have nervous systems that underlie behavior.

 

Example:         Nervous systems are formed from specialized cells that conduct signals rapidly through the long cell extensions that make up nerves. The nerve cells communicate with each other by secreting specific excitatory and inhibitory molecules.  In sense organs, specialized cells detect light, sound, and specific chemicals and enable animals to monitor what is going on in the world around them.

 

            3.         Like other aspects of an organism's biology, behaviors have evolved through natural selection.

 

Example:         Behaviors are often adaptive when viewed in terms of survival and reproductive success.  Behavioral biology has implications for humans, as it provides links to psychology, sociology, and anthropology. 

 

Twelfth Grade - Continued

Standard 3 - Continued

 

10***  4.         The basic biology, diversity, anatomy, ecology and medical effects of major animal groups.

 

Example:         Animals vary; this variation is important in understanding the function of animals in farming, medical research, etc.

Understanding the biology of animals underlies a scientific understanding of ecology.

 

5.                     That humans can be thought of as complex, soft machines that require many systems to operate properly.

 

Examples:       Organ systems have specific structures and functions; they interact with each other.

Infections, developmental problems, trauma, and aging result in specific diseases and disorders.

 

 10       6.         The structures and processes of development and reproduction.

 

Examples:       Reproduction is essential to all ongoing life and is accomplished with wide variation in life cycles and anatomy.

Understanding of basic mechanisms of reproduction and development, as well as changes of aging, is critical to leading a healthy life, parenting, and making societal decisions.

Environmental factors (e.g. radiation, chemicals) can cause inherited gene mutations that directly alter development or cellular repair mechanisms, leading to the development of various cancers.  Changes to non-reproductive cell lines are not passed to the next generation.
