AnP Chapter 1 (LO1) Flashcards
Define anatomy
The structure of the body
Define physiology
How the body functions
Define Pathophysiology
The study of the processes that disturb normal function
Patho means suffering or disease
Define Atoms
Smallest unit of matter
Define molecules
Atoms organized into various structures
Define organelles
The metabolic units within a cell that performs a specific function necessary to the life of the cell
Define cells
The smallest living units that make up the body’s structure
Define tissue
Specialized groups of cells with similar structure and function
Organs
Structures of two or more tissue types working together to carry out a particular function
Define a human organism
One complete individual
4 types of tissues
Epithelial tissue
Connective tissue
Muscle tissue
Nerve tissue
Define epithelial tissue
Covers or lines body surface
Ex outer layer of the skin, walls of capillaries and kidney tubes
Define connective tissue
Connects and supports parts of the body; some transport and stores materials
Ex bone, cartilage, and adipose tissues
Define muscle tissue
Contracts to produce movement
Ex skeletal muscles and the heart
Define Nerve tissue
Generates and transmits impulses to regulate body function
Ex brain and nerves
Define organ systems
Organs of each system contribute to a particular function
Some organs belong to more than one system
What are the 11 organ systems
Integumentary system Endocrine system Urinary system Circulatory system Nervous system Reproductive system Skeletal system Digestive system Muscular system Lymphatic system Respiratory system
What does the Integumentary system consist of and it’s key functions
Consists of skin, hair and nails
Key functions: protections, temperature regulation, water retention and sensation
What does the Sleletal system consist of and it’s key functions
Consists of bones, cartilage, and ligaments
Key functions: protection if organs, support, movement and blood formation
What does the lymphatic system consist of and it’s key functions
Consists of lymph nodes, lymphatic vessels, lymph, thymus, spleen and tonsils
Key functions: role in fluid balance, production of immune cells, defence against disease
What does the muscular system consist of and it’s key functions
Consists of skeletal muscles
Key functions: movement, posture and heat production
What does the Respiratory system consist of and it’s key functions
Consists of nose, pharynx, larynx, trachea, bronchi and lungs
Key functions: absorption of oxygen, discharge of carbon dioxide, acid base balance and speech
What does the Urinary system consist of and it’s key functions
Consists of the kidneys, ureters, urinary bladder and urethra
Key functions: excretion of wastes, regulation of blood volume and pressure control of fluid electrolyte and acid-base balance
What does the Nervous system consist of and it’s key functions
Consists of the brain, spinal cord, nerves and sense organs
Key functions: control, regulation + coordination of other systems, sensation and memory
What does the endocrine system consist of and it’s key functions
Consists if the pituitary gland, adrenals, pancreas, thyroid, parathyroids and other organs
Key functions: hormone production, control and regulation of other systems
What does the Circulatory system consist of and it’s key functions
Consists of the heart, arteries, veins and capillaries
Key functions: distribution of oxygen, nutrients, wastes, hormones, electrolytes, immune cells and antibodies; fluid, electrolyte and acid-base balance
What does the digestive system consist of and it’s key functions
Consists of the stomach, small and large intestines, esophagus, liver, mouth and pancreas
Key functions: breakdown and absorption of nutrients; elimination of wastes
What does the Male reproductive system consist of and it’s key functions
Consists of the testes, vas deferens, prostate, seminal vesicles and penis
Key functions: production and delivery of sperm, secretion of sex hormones
What does the female reproductive system consist of and it’s key functions
Consists of the ovaries, fallopian tubes, uterus, vagina and breasts
Key functions: production of eggs, site of fertilization and fetal development; birth, lactation, secretion of sex hormones
Define midline
Down the centre of the body splitting it i to right and left halves
Define medial
Toward the midline of the body
Define lateral
Away from the midline of the body
Define distal
Farthest from the point of orgin
