week 1 foundations of human physiology

physiology

physiology is the study of function of living systems such as cells, organs etc.

exercise physiology

a branch of physiology that looks into how the body adapts and reacts to exercise in both the acute or chronic time.

acute

short term

chronic

long term

sport and exercise physiology

covers both sport performance and exercise for health

chemical level

all atoms (e.g. hydrogen) and molecules (e.g. water, proteins)

molecules

made up of one or more atoms

cellular level

basic structural units of the body

tissue level

groups of cells that are the same

4 types of tissue

connective, muscle, epithelial and nervous tissu

organ level

different tissues combine to have a specific function for example the lungs

organ system level

several organs that work together to achieve something for example the digestive system

metabolism

the sum of all chemical processes that occur in the body. for example how quickly your body uses food as energy

responsiveness

the ability to react and respond to changes

movement

movement of cells of around the body and limbs

growth increase

size or number of cells

differentiation

unspecialised to specialised cells

reproduction

formation of new cells for growth or the creation of offspring

excretion

process of removing waste

homeostasis

a form of dynamic equilibrium the body detects a change and tries to set it back to normal. for example when exercising your body gets warm so you sweat to cool down.
