Objective56: Examine Differences in Metabolic and Respiratory Acidosis and Alkalosis

These charts broke it down in an easy to understand form. I was able to get a working knowledge of the subject from this website as well as the textbook.

Objective57: Justify the Role of Lacteals in Transporting Products of Digestion

Here is where I learned about lacteals role in transporting  products of digestion.

Objective61: State the Chemical Forms in Which the Major Food Classes are Absorbed

Pages 784-785 explain chemical digestion and absorption. I learned these classes are carbohydrates, protein, fat, and nucleic acid. The color coded chart helped me to see the differences in where they are absorbed and how.

Objective64: Discuss How Oxygen and Carbon Dioxide are Transported

This is where I learned about the transport of these gases in the body. They are transported in the blood as it is pumped through the heart and lungs. They are necessary for life. Several illnesses are attributed to abnormalities of this process.

Objective63: Describe the Structure and Function of the Renal Corpuscles and Renal Tubules

This page in the textbook (page 842) taught me about this subject. It explained the renal corpuscles and renal tubules in an easy to understand text. It also provided the basis for my understanding of the glomerular capsule and how loop of Henle contributes to the entire process.

Objective65: State the Importance of Juxtaglomerular Cells in the Secretion of Renin

This page in the textbook, (page 844), helped me understand the importance of the juxtaglomerular cells in the secretion of renin. The diagram was also helpful in my understanding of the process.

Objective62: Describe External and Internal Gross Renal System Anatomy

This website describes the internal renal anatomy while this one describes the External anatomy. Just like I learned most of the anatomy in this class, I labeled these diagrams several times until I became proficient at it. 

Objective47,53: Define Dalton's Law of Partial Pressure, Boyles Gas Law and Relate Both to Respiratory Physiology, Decide How Arterial Carbon Dioxide Concentrations Affect Ventilation

Boyle's Law

Boyle's Law basically states that gas pressure and volume are inversely related. What this means is that the smaller the space the gas is contained in, the greater the pressure of the gas in that container. Imagine that gas molecules are ping pong balls in a big box. They don't interact very much. Then you put the same amount in a smaller box and a smaller box, they interact more and more. As they interact more, the pressure increases.
Boyle's Law explains how the air gets in and out of your lungs, that is, how it travels through the conducting system and fills the alveolar sacs. It works like this: Gas pressure changes in your thoracic cavity in response to your muscles contracting and your ribcage expanding.

Daltons Law:
Dalton's Law of Partial Pressures describes how pressure gradients can facilitate diffusion for individual gases between your blood and lungs. And Henry's Law explains how gases can move into and out of solution—in the case of our bodies, how oxygen and carbon dioxide can dissolve and diffuse out of the blood

Objective48: Delineate the Role of Muscles and Lung Elasticity in Inhalation and Exhalation

I used these practice flashcards to learn the muscles of inhalation and exhalation. From the diaphragm and intercostals to the accessory muscles(serratus anterior and pecs), this was a good way for me to become familiar with the process and the muscles involved.

Objective36,39,40,42: Recognize Pathogen Types and Outline how the Body Protects Itself, Explain why Development of Self Tolerance is Important, Describe Cellular and Non-Cellular Immunity, Distinguish non-specific, Innate or Natural Immunity From Specific or Acquired immunity

This work was the best I could come up with to learn this subject. Immunity was not one of the more interesting subjects to me. I did what I could with it but found it very  dry.

Objective77: Recognize that a Blastocyte Secretes Human Gonadotropin, Which Prolongs the Life of the Corpus Luetum

This website helped me to understand the corpus luteum and how its life is prolonged by human gonadotropin.

Objective72: Evaluate Fertilization in Terms of Evolutionary Fitness

This video pretty much sums it up. Not much more to explain on this one. I wish I had something to add to the subject but I don't.

Objective46,49: Relate Breathing to Cellular Respiration, Contrast Inspiration and Exhalation

This small video does a great job in explaining inspiration and exhalation. It is broken down into simple concepts. It also helped me to understand the pressure differences and how that effects breathing. Its actually pretty simple once I got the concept. I also found it helpful to review cellular respiration to further my understanding of how breathing takes place. There are a lot of things that have to happen to keep us breathing. A lot of things we have difficulty with as we age. Even things down to the muscles of inspiration can keep us from getting the oxygen we need to properly breath.

Objective15: Discuss How the Adrenal Gland Responds to Stress

http://www.managingstress.com/articles/physiology.htm This was huge in allowing me to understand how the adrenal glands respond to stress. It also helped me to understand how they work with the central nervous system to create the fight or flight response. I find it amazing that such small glands can be so powerful and cause tremendous changes in the body. Especially without us consciously turning them on and off.

Objective11,12,13: Understand Structure and Function of the Endocrine System in Relation to Growth and Homeostasis, Name Hypothalamus-pituitary Complex Hormones and Give Their Functions, Name Hormones of the Gonads and Give Their Functions

The first thing I did was learn the organs of the endocrine system. Then I learned the hormones each produced.Finally, I learned how the hormones effected growth and homeostasis.

Objective2,3,6: Apply Critical and Integrated Thinking Skills, Solve for Unknown s by Manipulating Variables, Use Oral and Written Communication Skills to Explain Scientific Concepts

Comparing the slides of the histology of tissues really challenged my critical thinking skills. Manipulating the magnifications to differentiate them from one another took work. When I looked at the slides they all looked the same but when I applied what I had learned about a particular tissue I began to see differences. The type of epithelium it contained, the muscle tissue surrounding it, and the cells such as goblet that they contained. I think I got much better at distinguishing the tissues throughout  Bio 211.   MyA&P website on histology assisted in allowing me to compare the tissue.

Objective76: Differentiate Between Zygote, Morula, and Blastocyst

 http://www.ehd.org/movies.php?mov_id=6
This all occurs during the first week of being conceive.
Morula is the process where the zygote begins to divide and multiply into many cells.
A blastocyst begins at day 5 in mammals after fertilization.
A zygote is the initial cell formed after a sperm and egg have joined.

Objective73: Compare and Contrast Oogenesis and Spermagenesis

This video describes it about as simple as you can. I followed along in the chart as he explained it. The side by side comparisons are easy to follow as he spoke about mitotic division.

Objective8: Demonstrate Correct Care and Safe Use of Instruments, Equipment, and Living Organisms

This site refreshed my memory of the proper use of the equipment, mainly the microscope. I learned this stuff in biology 100 but refamiliarized myself with this site.

Objective71: Explore how Spermatozoa Move Through the Female Reproductive Tract

The spermatozoa moving through the female reproductive tract.(page 907-8) is easy to understand on this page of the book. The pictures are also helpful in applying the information to the anatomy. Pretty amazing, the way the body works especially in the reproductive system.

Objective74: Distinguish Between Diploid Germ Cells and Haploid Sex Cells

The differences are simply explained on this website. This is where I learned the differences in the number of chromosomes 23/46. I was able to understand the the process and how the cells divide. I learned that diploid cells are formed as a result of mitotic cell division whereas haploid cells(the sex cells) are formed in meiotic cell division. I like to learn from these videos that a chart to visualize the comparisons.
