Digestive, Skeletal, & Muscular System Flashcards
(39 cards)
Organ System:
1. System responsible for breaking down food into substances which can be absorbed and utilized by the body for growth and energy.
Digestive System
Organ System:
Digestive System:
Parts and their Functions:
1. The initial digestion that receives food by ingestion
Mouth
Organ System:
Digestive System:
Parts and their Functions:
1. Gland that releases a secretion called saliva into the oral cavity to aid in ingestion.
Salivary Glands
Organ System:
Digestive System:
Parts and their Functions:
1. Accessory digestive organ that helps in biting and chewing of foods.
Teeth
Organ System:
Digestive System:
Parts and their Functions:
1. Passageway that carries food to the esophagus and air to the lungs
Pharynx
Organ System:
Digestive System:
Parts and their Functions:
1. Muscular tube that carries food from the pharynx to the stomach through peristalsis.
Esophagus
Organ System:
Digestive System:
1. Involuntary wave-like contractions of muscles that are involved in the food movement in the digestive tract.
Peristalsis
Organ System:
Digestive System:
Parts and their Functions:
1. Mixing chamber and holding reservoir of food.
2. Produces a digestive fluid called hydrochloric acid
Stomach
Organ System:
Digestive System:
1. Digestive fluid that destroys harmful microorganisms present in the food particles.
Hydrochloric acid
Organ System:
Digestive System:
Parts and their Functions:
1. Produces enzymes that will help in digestion
Pancreas
Organ System:
Digestive System:
Parts and their Functions:
1. Removes toxin from the body’s blood supply
2. Produces bile
Liver
Organ System:
Digestive System:
Parts and their Functions:
1. Stores and secretes bile
Gallbladder
Organ System:
Digestive System:
Parts and their Functions:
1. Thin, long tube that further digests food
Small Intestine
Organ System:
Digestive System:
Parts and their Functions:
1. Thick, long tube that absorbs water and consists of bacteria that support the breakdown of waste
Large Intestine
Organ System:
Digestive System:
Parts and their Functions:
1. Passageway of feces for exit
Anus
Organ System:
Digestive System:
Phases of Gastric Secretion
- Cephalic Phase
- Gastric Phase
- Intestinal Phase
Organ System:
Digestive System:
Phases of Gastric Secretion:
1. Happens when the smell, sight, thought, or initial taste of food activates the facial, glossopharyngeal, and vagus nerve.
2. Prepares the mouth and stomach for food that is about to be eatem.
Cephalic Phase
Organ System:
Digestive System:
Phases of Gastric Secretion:
1. Phase in which swallowed food and semi-digested protein reaches the stomach and activates gastric activity.
Gastric Phase
Organ System:
Digestive System:
Phases of Gastric Secretion:
1. Begins once food enters the small intestine which stimulates secretion of gastric juice.
Intestinal Phase
Organ System:
1. System composed of all the bones and cartilages which support the whole body.
Skeletal System
Organ System:
Skeletal System:
1. An organ made up of several different tough tissues working together to provide structure and support to the body.
Bone
Organ System:
Skeletal System:
Types of Cells in the Bone Tissue
- Osteoprogenitor Cells
- Osteoblasts
- Osteocytes
- Osteoclasts
Organ System:
Skeletal System:
Types of Cells in the Bone Tissue:
1. Unspecialized bone stem cells
2. Only bone cells to undergo cell division, the resulting cells develop into osteoblasts
Osteoprogenitor Cells
Organ System:
Skeletal System:
Types of Cells in the Bone Tissue:
1. Bone-building cells
2. Synthesize and secrete needed substances to build the extracellular matrix of bone tissue.
Osteoblasts
