what the different between open and closed system

# data[].attributes.body
For open system it found in animal that have blood that not flow in blood vessel but in closed  system consist vein, capillaries and artery that carry blood.
Open system - Most available is in insect
Closed system - In human and large active animal

# data[].attributes.body
cockroach are one of open system.
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 :)

# data[].attributes.body
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 previous lesson we have learn about open and close circulatory system. Both of system has similar and differences. Besides that we also learned about circulatory system in human.

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)

Hi everyone, welcome to my padlet :)
this is all about Animal Physiology

# data[].attributes.body
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.

# data[].attributes.body
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.

# data[].attributes.body
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

# data[].attributes.body
there are two feedback which is positive and negative feedback.

This diagram show role of negative feedback

# data[].attributes.body
this is how homeostasis works to maintain internal condition.

# data[].attributes.body
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.

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.
