COMPLETE SOLUTIONS VERIFIED AND GRADED A+
Digestive System
Responsible for breaking down food for energy and growth; includes mouth, esophagus,
stomach, intestines, and associated organs.
Mouth
food is chewed and mixed with saliva, which contains
enzymes that help break down carbohydrates.
Esophagus
uses a series of coordinated muscle contractions
called peristalsis to move the food down to the stomach.
Stomach
food is mixed with gastric juices, which contain
hydrochloric acid and enzymes that break down proteins.
Small Intestine
The majority of the nutrients from the food are
absorbed into the bloodstream.
large intestine
The last section of the digestive system, where water is absorbed from food and the
remaining material is eliminated from the body
Rectum
A short tube at the end of the large intestine where waste material is compressed into a
solid form before being eliminated
anus
A muscular opening at the end of the rectum through which waste material is eliminated
from the body
Peristalsis
Coordinated muscle contractions in the digestive tract to move food.
, Chyme
Mixture of food and digestive juices produced in the stomach.
Villi
Tiny projections in the small intestine for nutrient absorption.
Liver
produces bile which helps breakdown fats in small intestine
Pancreas
Regulates the level of sugar in the blood
Gallbladder
A muscular sac attached to the liver that secretes bile and stores it until needed for
digestion
Muscular System
Allows manipulation of the environment, locomotion, and facial expression. Maintains
posture, and produces heat.
Skeletal Muscle
Largest and lmost numerous type of muscle cells in the body. Attached to bones for
voluntary movements like walking.
actin and myosin
contractile proteins in muscle
Smooth Muscle
Involuntary muscle in internal organs like the digestive system.
Cardiac Muscle
Muscle in the heart responsible for rhythmic contractions.
Integumentary System
It serves to protect the body from
external damage, regulate body temperature,
and help with sensory perception.
Epidermis
Outermost skin layer composed of keratinocytes.
Dermis
