Anatomy
Study of the structure of the body and how body parts are organised & the relationship between body parts.
1 of 17
Physiology
Study of the functions of body parts, what they do and how they do it.

What Are The 4 Main Tissue Type?
*Connective
*Epithelial
*Muscle
*Nervous
3 of 17
Organs
Two or more tissue types work together for specific functions
4 of 17
Body Systems
Organs join together to carry out vital functions e.g. the heart and blood vessels form the cardiovascular system, circulating blood throughout the body to ensure all body cells receive nutrients

*Muscular
*Respiratory
*Digestive
*Urinary
*Reproductive
*Nervous
*Endocrine
*Cardiovascular
*Lymphatic
*Circulatory

What is Homeostasis?
The tendency or ability of an organism or a cell to regulate its internal conditions, usually by a system of feedback controls, so as to stabilise health and functioning, regardless of the outside changing conditions
8 of 17
How is the Body regulated?
*Receptors
*Processing centre
*Effectors
9 of 17
Receptors
Detect things such as temperature change
10 of 17
Processing centre
Receives information & coordinates a response
11 of 17
Effectors
Produce a response that ensures a constant body temperature at approx. 37 degrees
12 of 17
Negative Feedback Control System
Responds when conditions change from the ideal or set point and returns conditions to this set point.

Continuous cycle of events in negative feedback:
Change detected Feel hot)---> corrective mechanisms activated (Remove cardigan) ---> conditions retur

Negative feedback
Ensures that, in any control system, changes (abnormalities) are reserved and returned back to the correct level

Negative feedback systems example:
Negative Feedback keeps body temperature at a constant 37 degrees.
*If we get too hot, blood vessels (in the skin) vasodilate. (We lose heat & body cools down)
*If we get too cold, blood vessels (in the skin) vasoconstrict (We lose less heat & our body wa

Homeostasis (INFO)
* maintaining the internal environment of the body as a state of equilibrium.

*Essential to survival e.g. blood sugar levels, body temperature, heart rate and fluid environment for cells.
*Homeostatic control has 3 components: A receptor, Control Centre
16 of 17
Homeostasis (CONTD)
*The body uses negative or positive feedback loops to maintain or restore homeostasis
*Feedback loops involve a sensor, a control centre and an Effector
