The digestive and excretory systems together function
to process all nutrients that enter the bloodstream except
the oxygen that is brought in by the respiratory system. Through the digestive system, nutritive substances are absorbed and any that are not are eliminated.
How does the excretory and digestive system work together?
The excretory system removes waste from the body. remove waste from the blood. The digestive system breaks down the food you eat into nutrients that provide energy and building materials for cells. The digestive and excretory sytems work together
to process the food that you eat
.
Which organ works in the digestive and excretory systems?
The circulatory system also carries chemical signals from your endocrine system that control the speed of digestion. The digestive system also works in parallel with your excretory system (
kidneys and urination
).
What are the correct pathways of food in digestive system?
- Mouth.
- Esophagus.
- Stomach.
- The small intestine.
- Colon (large intestine)
- Rectum.
How does the digestive system remove waste?
The body expels waste products from digestion through the rectum and anus. This process, called
defecation
, involves contraction of rectal muscles, relaxation of the internal anal sphincter, and an initial contraction of the skeletal muscle of the external anal sphincter.
What are the 14 parts of the digestive system?
The main organs that make up the digestive system (in order of their function) are
the mouth, esophagus, stomach, small intestine, large intestine, rectum and anus
. Helping them along the way are the pancreas, gall bladder and liver.
What are the 10 steps of the digestive system in order?
The digestive processes are
ingestion, propulsion, mechanical digestion, chemical digestion, absorption, and defecation
.
Which part of the digestive system starts the breakdown of proteins?
Mechanical digestion of protein begins
in the mouth
and continues in the stomach and small intestine. Chemical digestion of protein begins in the stomach and ends in the small intestine. The body recycles amino acids to make more proteins.
What does the rectum do in the digestive system?
Rectum: An 8-inch chamber that connects the colon to the anus. The rectum
receives stool from the colon
, sends signals to the brain if there is stool to be evacuated, and holds stool until evacuation can happen.
Which part of the digestive system eliminates waste in the body?
Finger-like projections called villi line the interior wall of the small intestine and absorb most of the nutrients. The remaining chyme and water pass to
the large intestine
, which completes absorption and eliminates waste.
How many feet of intestines do you have in your body?
Research suggests that the combined length of the small and large intestines is
at least 15 ft in length
. The small intestine can measure about 9–16 ft, while the large intestine is roughly 5 ft long. The intestines have the important role of helping break down and absorb nutrients from food and drink.
How does the human digestive system work step by step?
- Step 1: Mouth. To more easily absorb different foods, your saliva helps break down what you’re eating and turn it into chemicals called enzymes.
- Step 2: Esophagus. …
- Step 3: Stomach. …
- Step 4: Small Intestine. …
- Step 5: Large Intestine, Colon, Rectum and Anus.
What are the 15 parts of digestive system?
The main organs that make up the digestive system (in order of their function) are
the mouth, esophagus, stomach, small intestine, large intestine, rectum and anus
. Helping them along the way are the pancreas, gall bladder and liver. Here’s how these organs work together in your digestive system.
What are the two types of digestion?
Digestion is a form of catabolism or breaking down of substances that involves two separate processes:
mechanical digestion and chemical digestion
. Mechanical digestion involves physically breaking down food substances into smaller particles to more efficiently undergo chemical digestion.
What are the 7 steps of the digestive system?
The digestive processes are
ingestion, propulsion, mechanical digestion, chemical digestion, absorption, and defecation
. Some chemical digestion occurs in the mouth.
What are the 6 steps of digestion?
The six major activities of the digestive system are
ingestion, propulsion, mechanical breakdown, chemical digestion, absorption, and elimination
. First, food is ingested, chewed, and swallowed.
