Human Anatomy: Lecture 1 15:50
Physiology = study of how the body functions
Developmental anatomy: examines structural changes over time
Comparative anatomy: considers all types of animals
Types of Organ Systems
Integumentary system: protection from environmental hazards ( temp
control)
Skeletal system: support, protection of soft tissues, mineral storage,
blood formation
Muscular system: locomotion, support, heat production (one muscle acts
on a joint and ends a muscle)
Nervous system: directing immediate responses to stimuli, usually by
coordinating the activities of other organ systems
Endocrine system : directing long-term changes in the activities of other
organ systems
Cardiovascular system: internal transport of cells and dissolved materials,
including nutrients wastes and gases (blood in the heart is on a two way
system)
Lymphatic system : defence against infection and disease
Respiratory system : delivery of air to sites where gas exchange can
occur between the air and circulating blood (capillaries are the smallest
blood vessels )
Digestive system: processing of food and absorption of organic nutrients,
minerals, vitamins and water (mouth to ass one huge tube nigga)
Urinary system: elimination of excess water, salts, and waste products
(huge control of pH)

Oblique : on an angle (diagonal )
Frontal or Coronal Plane: serperates the anterior and posterior (back from
front)
Sagittal Plane : Separates right and left portions

half
Parasagittal section : Misses the midline, separating unequal half’s
