First of all i would like to tell you a little bit about animal physio.

what is animal physio ?
Animal physiology is the scientific study of the life-supporting properties, functions and processes of animals or their parts. The discipline covers key homeostatic processes, such as the regulation of temperature, blood flow and hormones.]]> 2018-03-17 09:14:14 UTC https://padlet.com/d066970/gbsdnvip5bfh/wish/243049843 d066970 https://padlet.com/d066970/gbsdnvip5bfh/wish/243051275
Hi everyone, welcome to my padlet :)
this is all about Animal Physiology]]> 2018-03-17 09:25:40 UTC https://padlet.com/d066970/gbsdnvip5bfh/wish/243051275 d066970 https://padlet.com/d066970/gbsdnvip5bfh/wish/243052325 The human body is extremely complex machine. We are all made up of many different systems that work simultaneously together like one whole unit. That means if one of the systems malfunction then more likely other systems will follow as well because they all work together. Just like a machine, the human body needs be cared for, taken care of, and maintained to be run at full efficiency. ]]> 2018-03-17 09:37:31 UTC https://padlet.com/d066970/gbsdnvip5bfh/wish/243052325 d066970 https://padlet.com/d066970/gbsdnvip5bfh/wish/243052531 we have learned about homeostasis.
* Homeostasis is maintenance internal constancy.
* maintenance of internal condition within tolerable limits.

there are several factor that affecting homeostasis :
1) amount of energy
2) oxygen & carbon dioxide concentration
3) waste product
4) pH
5) water, salt and electrolytes
6) volume &pressure
7) temperature 
8) social parameters

This diagram show role of negative feedback ]]> 2018-03-17 10:00:18 UTC https://padlet.com/d066970/gbsdnvip5bfh/wish/243054307 d066970 https://padlet.com/d066970/gbsdnvip5bfh/wish/243063003 2018-03-17 11:26:45 UTC https://padlet.com/d066970/gbsdnvip5bfh/wish/243063003 d066970 https://padlet.com/d066970/gbsdnvip5bfh/wish/243063270 instead of homeostasis there also has non-homeostasis which called Rheostasis.
* Rheostasis is reset system which is changes the temporarily, permanently or cyclically.
* eg : fever, changes in  hormone concentration and reproductive cycle.]]> 2018-03-17 11:30:08 UTC https://padlet.com/d066970/gbsdnvip5bfh/wish/243063270 d066970 https://padlet.com/d066970/gbsdnvip5bfh/wish/243063824 How nervous system works ?
how the signal sent to the entire part of the body? 

All this involved the neuron.
Our body fill with billions of neuron that helps nervous system function.

Before we go more details about nervous system, let me show you the part of neuron.

Both of system has similar and differences. Besides that we also learned about circulatory system in human. ]]> 2018-04-25 05:39:19 UTC https://padlet.com/d066970/gbsdnvip5bfh/wish/255099459 d066970 https://padlet.com/d066970/gbsdnvip5bfh/wish/265928755 The important of Respiratory system is :
1) provide oxygen
2) eliminates carbon dioxide
3) defense against microbes
Human Respiratory System involves two :
a) inspiration (breath in)
b) exhalation (breath out)

It consists of 3 components heart, blood vessels and blood.
Variations of cardiovascular system in vertebrates  consist of fish, amphibian and mammal.

This is example of closed system in human.
It has 4 chambers heart and double circulation and pulmonary circuit and systemic circuit.
the blood has red in colour which different with closed system.
It is consist haemoglobin which leads to red colour.  
The left side of the heart handles only oxygen rich blood, while the right side receives and pumps only oxygen-poor blood.

for open system there are 4 components which is :
blood
heart
sinuses
alary muscles

There are 3 parts on cockroach which is pericardial that consist heart, perivisceral and perineural. The blood colour is white because the absent of haemoglobin. It is not as closed system which transport gases but it transport all nutrient through to all organ of the body. It used Malphigian tubules to excrete waste product.

How closed system works?
heart consist 30 chambers. blood will flow from postrial chamber to presiding 30 to 12 to 11 chamber. it also consist ostia. The contraction and relaxation that 
occur in alary muscle(triangular shape) that forcing blood into heart through pore. When alary contract blood will flow from body cavity which perineural & perivisceral sinuses into pericardial.

this is the diagram of closed system in cockroach by me :)

Open system - Most available is in insect 
Closed system - In human and large active animal]]> 2018-06-14 05:03:46 UTC https://padlet.com/d066970/gbsdnvip5bfh/wish/267140249
