Introduction to Physiology

Physiology delves into the study of how the human body functions, emphasizing the organization from cells to complex organ systems. Each organ system comprises multiple organs, which in turn are made up of tissues.

The body Organization The body is composed of several organ systems
Organ System An organ system is composed of one or more organs

Reproduction

reproductive system

Sensory input and motor output

muscular system

the contraction of these muscles moves the skeletal system to provide movement

body's muscles

skeletal system

provides support and works with the muscular system to provide movement

bones

integumentary system

the sensory receptors of this system sense external stimuli

accessory systems

skin

Control of the body systems

endocrine system

these messages help control bodily functions

the glands secrete chemical that serve as messengers between body parts

hormonal glands

nervous system

nerves

spinal cord

brain

Body maintenance

deliver and remove substances from the body's tissues

the urinary system

removes excess water and salts from the blood and excretes them in the urine

urine conducting tubes

bladder

kidneys

the respiratory system

provides gas exchange for the cardiovascular system

tubes - through which air moves

lungs

the digestive system

processes and extracts nutrients from food

composed of the organs of the digestive tract and peripheral components

pancreas

liver

teeth

Transport of f luids

lymphatic system

collects excess fluid and fat

returns it to the heart

from the body

consist of

lymphatic vessels

lymph fluid

lymph nodes

cardiovascular system

carries blood through the body to

remove wastes

deliver nutrients

consist of

blood vessels

heart

Organs An organ is composed of tissues

The function of organ system is similarly dictated by the organ present

Organs integrate the function of different tissues, providing functions that the individual tissues lack.

Organ are composed of one or more tissues

Tissues Tissues are composed of cells
Cells

Introduction

Scientific Method

Determine how organisms, organ systems, organs, tissues, cells and bio- molecules (molecules & atoms) carry out the chemical or physical function that they have in a living system.
Definition
the branch of biology that deals with the study of all the parts of living organisms
Physiology (Greek, physis, meaning "nature") refer either to the parts or functions (mechanical, physical & biochemical) of living organisms
