GaSTRoiNTesTiNaL SYSTeM!
Basically, it performs 6 steps:
- Ingestion
- mastication
- digestion
- secretion
- absorption
- excretion.
So the mouth chews food and mixes it with saliva; forms food into bolus and swallows. The esophagus then moves bolus to the stomach through peristalsis. The stomach will store and churn food while the food mixes with digestive juices. When the “food” is in the small intestine, the small intestine will secret enzymes, receive secretions from the pancreas and liver, neutralize the acidity in chime, and absorb nutrients into the bloodstream and lymphatic system. The large intestine will finally create and absorb fat-soluble vitamins, reabsorbs water, forms and eliminates feces.
The Lymphatic and Immune Systems
Let’s start with the lymphatic system first.
So the lymphatic system is both the transport system and barracks of the immune system. It recycles lost fluids form the cardiovascular system, transports pathogens to the lymph nodes where they can be destroyed, store and mature some types of WBC and absorbs glycerol and fatty acids from food.
It consists of lymph capillaries, vessels, trunks and ducts containing lymphatic fluid and lymph nodes.
The immune system…
Ok.., its function is to ignore self-antigens and respond to non-self antigens. It is divided to innate and adaptive immunity.
Innate immunity is nonspecific, has no memory and cannot improve performance with experience. Adaptive immunity, on the other hand, is exactly the opposite of immunity. (I Suppose)
So what else? The immune system uses different types of cells to fight pathogens. There are also barriers that can be either physical or chemical (like the skin and tears).
I think illustrations, graph and other visual aids will help in teaching this lesson.

Respiratory System (It’s a Gas!)
Our lesson is all about the respiratory system.
So what have I learned? Here they are…
Ok… I guess that’s all I can remember right now.
Well… teaching suggestions? Illustrations will be very helpful especially in discussing about the process of breathing itself
So what have I learned? Here they are…
- The respiratory system is consists of 2 lungs, upper and lower airways, terminal air sacs (alveoli), a thoracic cage and muscles of breathing
- There are two processes of breathing: ventilation and respiration.
- The upper airways of the respiratory tract are in charge for initially conditioning the inhaled air.
- The lower respiratory tract? Hmm... I can’t recall anything about it...
- The diaphragm is the main muscle of breathing.
Ok… I guess that’s all I can remember right now.

cardiovascular system :)
the major components of the cardiovascular system include the heart, blood and the blood vessels.
the heart is an organ that is actually two pumps working together to move blood. it's right pump moves blood collected from the body to the lungs, where oxygen is loaded and carbon dioxide is removed to be exhaled by the lungs while the left pump takes the freshly oxygenated blood and pushes it through the body so tissue cells can be kept healthy.
the blood is a form of connected tissue that has a fluid component called plasma and a variety of cells and substances. it also transports oxygen from the lungs, nutrients and fat cells from the digestive system and hormones from the endocrine glands to approximately 75 million cells in the body. amazing. right? :)
so there are three types of blood vessels. arteries, veins and capillaries.
arteries carry blood away from the heart while the veins carry blood to the heart. and the capillaries allows for the transfer of oxygen and nutrients to the tissues in the body.
whew. this lesson is particularly long and complicated (for me). so in teaching this kind of lesson, its nice to have organizational concept maps to sum up all of the important detail. the reporter did a very good job. :)
ok. that's all.. thank you :))

The Special Senses
So, the senses of sight, sound and equilibrium, taste and smell are what we call the special senses.
The eye is very similar to a camera, with lens cover of the eyelids, opening (pupils), shutter (iris), lens (eye lens) and photoreceptive (retina). The eyes has many parts with different functions but I can't remember all of them anymore. :)
On the other hand, the ear has three major divisions: the external, middle and inner ear. The ear is the organ for hearing and maintaining our sense of balance.
The other senses include taste,smell and touch.
I guess that's all that i can remember right now. :)
Illustrations will help in teaching this lesson so that the parts can be easily remembered. :))

endocrine system :))
Endocrine System...
well..this was the first lesson for the third quarter.
The Endocrine System is often called as the “Body’s Other Control System”. It is a series of organs and glands that secrete hormones into our bloodstream.
So speaking of hormones, hormones are chemical messengers released by the endocrine glands. These hormones bind to receiving cells to control the cell activities. There are three sources of hormone levels, the nervous system (neural control), other hormones (hormonal control) and body fluids (humoral control)
The major Endocrine Organs are the Hypothalamus, Pituitary gland, Thyroid gland, Thymus gland, Pineal gland, Pancreas, Adrenal glands, and the Gonads.
The hypothalamus controls pituitary hormone levels. It also secretes a number of hormones like GHRH, GHIH, CRH and other more.The pituitary gland controls other endocrine organs by releasing different types of hormones.The thyroid gland releases thryroxine and triidothyronine that controls cellular metabolism and calcitonin that decreases blood calcium.Pineal gland releases melatonin which is believed to regulate sleep.The pancreas secretes insulin and glucagon that lowers and raises blood sugar respectively.The adrenal glands produces epinephrine and norepinephrine which is responsible for fight-or-flight response. It also produces adrenocorticisteroids which has many different effects.Finally, the gonads (ovaries in females, testes in males) releases estrogen, progesterone and testosterone that controls sexual reproduction and secondary sexual characteristics.
I was the reporter of this particular lesson and I could say that I did a very horrible report. Waaa! I know that my classmates didn’t understand my report and no one passed on the check-up quiz about it! I felt bad about it so suggest that if you are going to report this lesson, visual aids are really needed since the terms are hard to remember easily.
