ready for the finale.........NOT!

like i said in my last post, i m done with all my background research for this question. n i also decided to stick with that cows have four stomachs.....cause tats what all the website r saying. need mor reliable sources before i can safely say tat the four stomachs r actually digestive components.

anyway, in the following week i would be summarising n finishing this question. all tat is left now is making a table n wait to hear wat ppl know about this question on yahoo answers.

look forward to the finale next next week!

almost done....wait! a new fact????

k i m also done with all the research i need for this topic. by next week i should be able to summarise my results. all i have to do next is to wait for more answers from yahoo answers. i think i should not go to more websites as it might cause me to get messy with all the data. so research stops here................WAIT!!!!! wats this? someone say that Actually cows do NOT have four stomachs. They have a four compartmented digestive system but have one true abomasum ..which like our stomach has pepsin and HCl.(dunno wat the last few words mean though)

oh dear...so they r not actually stomachs but r digestive compartments? hmm...need to find out more on these "compartments", though it wont really affect my entire question as regardless of wat they r, they still do the same thing cause they r afterall the same objects, just with a different name.

Back to the cow!

ok, now its time for me to go back researching about the cows digestive system. since my last post on the topic, i only know the digestion process. still, little is known about the four stomachs. today i wen to find out more about them. this is wat i got from the website which i think is the easiest to understand.

Ruminant animals, such as the dairy cow, have four stomach compartments called the rumen, reticulum, omasum, and abomasum. The rumen is the largest and can hold up to 40 gallons of digesta and contains billions of bacteria, protozoa, fungi, and other organisms. The bacteria can digest fiber allowing the dairy cow to consume grass, forages, and fibrous by-product feeds that humans or monogastric animals cannot do effectively.

The abomasum is the stomach compartment similar to the human stomach.

btw, i post my both my biojournal questions on yahoo answers. so if u know anything, i hope u can help enlighten me. thx.

CHIM CHIM CHIM!!!!!!!!!!!!!!!

Ok, there's still no videos on the cow's digestive system, even the pictures found seems to be only in a samll amount. well, at least i got one naming the four stomachs and got some info of its digestion process though its not very detailed....


As for the digestion process, here are the few steps

1. The cow tears and chews the food briefly then swallows. She'll eat for more than six hours a day.
2. The food passes into stomach #1 to soften. When the food passes into stomach #2, it mixes and softens more into what is called cud.
3. When Ms. Cow feels full, she burps up a small amount of cud to chew it again. She'll chew her cud for eight hours each day.
4. When the cow swallows again, the cud passes into stomachs #3 and #4 where it is digested further and nutrients are absorbed.
5. Digested food passes through her intestines where more nutrients are absorbed. Waste materials exit the cow as manure.

woah, and according to the source, a cow had to chew at a rate of 50 times per minute. In one day, she move her jaw more than 40,000 times!
Tough life it must have....

Listening better than reading...

Firstly, i decided to split the research into one week for each question. So this week, i would be studying on the differences between a cow's digestive system and a human's digestive system.

Of course, the first thing i had to do is to find out more on the human digestive system. Mind u, it is not just covering our primary sch stuffs. anyway i went to wikipedia and OMG! all the words were greek to me, i dont even understand half of wat its saying. then i thought, wat if i go look for a video presentation, maybe it would be easier to understand.....

And it sure was! i enclose this post with that video tat i found on youtube.

Enjoy! ^^
