HUMAN ANATOMY AND PHYSIOLOGY Flashcards
ANATOMY
the study of structure and form
PHYSOIOLOGY
the study of function
METABOLISM
-the whole sum of reactions that occur throughout the body within each cell and that provide the body with energy
-this energy gets used for vital processes and the synthesis of new organic material.
CATABOLIC
-catabolic reactions break down larger molecules, such as carbohydrates, lipids, and proteins from ingested food, into their constituent smaller parts
-include the breakdown of ATP, which releases the energy needed for metabolic processes in all cells throughout the body
ANABOLIC
-anabolism is the process by which the body utilizes the energy released by catabolism to synthesize complex molecules
-these complex molecules are then utilized to form cellular structures that are formed from small and simple precursors that act as building blocks
TISSUES
-tissue is a group of cells that work together to perform a function
-4 types:
1.epithelium
2.connective tissue
3.muscle
4.nerves
EPITHELIUM
covers the body surface
CONNECTIVE TISSUE
connects, supports and protects
MUSCLE
move and generate heat
NERVES
carry information through the body
ORGANS
organs contain two or more tissue types
ORGAN SYSTEM
organ system is defined as multiple related organs with a common function
ORGANISM
organism is the highest level of organization, is a collection of organ systems making up an organism
ANATOMICAL POSITION
standing upright with feet parallel and flat on the floor, the upper limbs at the sides of the body, and palms facing forwards
SUPERIOR
closer to the head
INFERIOR
away from the head
ANTERIOR (ventral)
towards the front
POSTERIOR (dorsal)
towards the back
MEDIAL
towards the midline
