Study of the structure and shape of the body and their body parts and how they relate to each other.
What is Physiology?
The study of how the body and its parts work or function
What is homeostasis?
Is your body’s ability to maintain healthiness even though there is continuous change in the outside world. When the body’s needs are being met, the body is in a homeostatic state
FCL
Communication in the body is essential for homeostasis to occur. The communication networking is called a “feedback control loop.” When the body self regulate
4 Components of FCL
Sensor Mechanism (brain saying pain)
Control or Integrator Center (Body felling the pain)
Effectors' mechanism (your response to the pain)
Feedback( your body saying if the effectors worked or not)
What Does the Body Do?
1) Maintaining Boundaries
the out side germs stay away from the inside of your body
2) Movement
muscular system promotes movement
3) Responsiveness (irritability)
Is the 1 and 3 component in FCL
4) Digestion
breaking down of food for absorption
5) Metabolism
all chemical reactions within the body
6) Excretion
is the removing waste
7) Reproduction
responsible for producing offspring
8) Growth
increase in the size of a body part
LEVEL OF THE ORGANIZATION
● Chemical Level
Building blocks of nature – it has atoms
molecules
● Cellular Level
Cells –is the most numerous structural units of living matter.
● Tissue Level
Is a group of many similar cells that all developed together from the same part of the embryo and all perform a certain function.
● Organ Level
The structure is made up of several different kinds of tissues to perform a special function.
For example – Heart
Other Examples…….
● System Level
Is the most complex organization of the organizational units
it Involves different organs coming together to perform a complex function.
●Organism Level
“The Human Body”
Survival Needs
Nutrients
Oxygen
Water
“Normal” Body Temperature
Appropriate Atmospheric Pressure (the force that air exerts on the surface of the body)
The “amounts” are important to ensure quality of life.
(When the body’s needs are being met, the body is in a homeostatic state)
ANATOMICAL POSITION
Body is erect.
Arms at side.
Palms forward.
Head and feet forward.
Body planes
Ipsilateral – on the same side
Contralateral – opposite sides
Bilateral Symmetry- The left is the same as the right
BODY CAVITIES
Ventral Cavity – Includes the thoracic (chest) cavity and the abdomino pelvic cavity.
Dorsal Cavity – Includes the cranial cavity and spinal cavity
BODY PLANES
Sagittal Plane -Divides the body into left and a right
Transverse Plane (Cross) - Divides the body into superior and inferior
Frontal Plane (Coronal)Divides the body into anterior and posterior
