What is a tissue? |
A collection of cells that act together to preform a function. |
|
|
What are the 4 main types of tissues? |
• Epithelial • Connective • Muscle • Nervous |
|
|
Epithelial Tissue |
Tissue covers and lines much of the body (skin, mucus membranes). |
|
|
Connective Tissue |
Tissue is found all over the body and primarily holds things together and provides structure (cartilage, fat). |
|
|
Muscle Tissue |
Tissue provides the means for movement by and within the body. There is Skeletal (voluntary and attached to bone), Cardiac (involuntary and found in the heart) and Smooth (involuntary and found in hallow organs). |
|
|
Nervous Tissue |
Tissue transmits 'messages' and is made of neurones and neuroglia. |
|
|
Describe the chain that forms our Organ and Body System |
Atoms => Molecules => Cells => Tissue => Organ=> Organ and Body System |
|
|
What is an organ? |
2 or more types of tissues organized in a way that can do a task that the tissues can't do on their own. Some are vital (heart, brain, kidney, lungs) while some are not vital (spleen, gull bladder). |
|
|
How is and organ or body system formed? |
By organs and other structures that work together to accomplish something more complex than what a single organ can do. |
|
|
Give 3 examples of an organ or body system |
• Skeletal system • Muscular system • Cardiovascular system |
|
|
What is anatomy? |
A Greek word meaning 'to cut apart'. It is the study of internal and external structures of the human body. |
|
|
What is physiology? |
Focuses on the function and vital process on the various structures making up the human body. |
|
|
What are anatomy and physiology closely related? |
Physiology is the study of how an anatomical structure actually functions. |

What is hemostasis |
The physiological process that monitors and maintains a stable internal environment or equilibrium. Survival depends on our ability to maintain hemostasis. |
|
|
What does hemostasis regulation refer to? |
The adjustments made in the human organism to maintain a stable internal environment. |
|
|
When will the hypothalamus in the brain use a negative feedback loop to control body temperature and maintain homeostasis? |
If it gets a message that your body is cold it will do things to warm it. |
|

|
What is a negative feedback loop? |
When the feedback opposes the stimulus. |
|
|
What is a positive feedback loop? |
It increases the magnitude of a change versus resisting change. Known as a viscous cycle. This is not a way to regulate your body because it increases a change away from a set point. Often harmful if cycle cannot be broken. |
