Quiz 10 Flashcards
Organ System
- Definition
• groups of organs in the body work together to accomplish specific functions
Skeletal Muscle (3)
- functions
- process
• bound to the bones of the skelton by TENDONS
- when Skeletal muscles contract, the bones of the skeleton to which they are attached move
- (MOVEMENT OF SKELETON RELIES ON MULTIPLE SKELETAL MUSCLES) movement of the skeleton rely on the coordinated effort of multiple skeletal muscles, not the action of one isolated muscle
Respiratory Organs (2) - functions
- designed to ensure atmospheric air is filtered, moistened, and warmed before reaching the alveoli
- these actions increase the efficiency of gas exchange between the lungs and the blood at the level of the alveolus
Digestive System Organs (2)
- function
- process
• break down ingested food mechanically and enzymatically into sizes small enough to be absorbed by cells lining the G.I. tract
- (OCCUR IN STEPS) these processes occur in a series of steps as food is transported from one highly specialized digestive organ to the next
Submandibular Glands (2)
- location
- function
- major salivary glands located along the base of the mandible
- these glands secretes saliva which contain salivary amylase that chemically digests carbohydrates in the oral cavity
Thyroid (2)
- function
- visual (3)
- endocrine gland where hormones serve to regulate the basal metabolic rate and blood calcium levels
- it is a brown, butterfly-shaped gland lying just below the larynx
Larynx (3)
• contains the vocal cords
- is continuous with the Trachea
- serve as air conducting passageways
Trachea
- serve as air conducting passageways (along with larynx)
Lungs
- Terminate in microscopic alveoli which function in gas exchange
Thymus Gland (3)
- which system ?
- location
- over time ?
- organ of immune system
- located above the heart
- in older animals it begins to atrophy and is replaced by fat
Esophagus (2)
- definition
- process
- muscular tube serving to conduct food from the pharynx to the stomach
- (THORACIC CAVITY -> DIAPHRAGM = STOMACH) it passes through the thoracic cavity and pierces the diaphragm to join the stomach
Stomach (3)
- most dilated of the GI tract
- It functions in the mechanical digestion of food and, by the action of the enzyme pepsin, it begins the chemical digestion of the protein
- stomach joins the duodenum
Duodenum
• the initial segment of the small intestine
Small Intestine
• serves as the primary site of nutrient absorption of the GI tract
Large Intestine
• functions primarily in the absorption of water which compacts the feces and to a limited degree, vitamin synthesis
Cecum (2)
• the initial segment of the large intestine
- a large blind - ended sac
Rectum
• the terminal region of the large intestine
Liver (5)
- visual
- location
- function (3)
- large, dark brown, multi-lobed organ
- located below the diaphragm
- bile synthesis
- detoxification of waste products
- glycogen storage
Spleen (3)
- visual
- location
- function
- dark brown
- connected to membranes to the stomach
- (STORE BLOOD; BLOOD CELL REMOVAL) functions to store blood and is the site where blood cells are removed from the circulation and destroyed
Pancreas (5)
- visual
- location
- secretion of: (3)
- light brown, flat organ
- located in a mesentery below stomach
secretion of:
- digestive enzymes
- buffers
- hormones
Rugae
Folds in the wall
