Serous Membranes

covers viscera within ventral cavities, lines walls or thorax and abdomen

What are the 2 layers of the serous membranes? What do they do?

Parietal layer: lines walls of cavities Visceral layer: covers organs

2 Pleural Cavities (pleura)

visceral pleura: covers lungs Parietal Cavity: lines the pleural cavity

Name of membranes in the 3 body cavities

Pleural cavity, pericardial, abdominal pelvic, serous membranes, cutaneous membrane, mucous membrane

What are the 11 organ systems?

integumentary, skeletal, muscular, nervous, endocrine, cardiovascular, lymphatic, respiratory,digestive,urinary,reproductive

define Integumentary System/ function?

body covering Function: protect underlying tissues, regulate body temp, house sensory receptors

Define Skeletal System/function?

support and movement Functions: provides framework for body muscle attachment and protection

Define Cardiovascular System/Function

transport function: transport gases, hormones, and wastes

Define Nervous System/ Function

Integration and coordination functions: detect, evaluate, and respond to change

Define Muscular System/function

support and movement functions: contracting and expanding allows for body movement

Define Endocrine System/function

integration and coordination function:secrete hormones to alter metabolism

Define urinary system/ function

absorption and excretion functions: excretion-remve wastes from blood, maintain water andion balance

Define Female Reproductive system/ functions

fertilization, production of egg, supports the growth of embroyo and fetus, birth fund: produces whole or new organisms similar to itself

Define Male Reproductive System/ Function

production of sperm, fertilization Function: produces whole new organisms similar to itself

Lymphatic System/function

transport functions: transport fluid(fats), defend against infection

Digestive System/function

absorption and excretion function:receives and breaks down food, absorbs nutrients

Respiratory System/function

absorption and excretion function: take in and exchange gases with air
