Create a mindmap that consolidates the "Digestive System" & "Respiratory System".
Respriatory System
Nose
Mouth
Trachea
Lungs
Bronchi
Bronchioles
Bronchioles end in tiny air sacs called alveoli
Alveoli
Exchange of oxygen and carbon dioxide takes place
1 more item...
There are hundreds of millions of alveoli the lungs
The bronchi branch into smaller bronchi
The smaller bronchi branch into and even smaller tubes called bronchioles
Trachea divides into left and right air tubes called bronchi
These connect to the lungs
The network of alveoli, bronchioles, and bronchi are known as the bronchial tree.
Exchange of gas
Lungs work with the circulatory system to pump oxygen-rich blood to all cells in the body
The exchange of air between the atmosphere and the lungs
Cellular respiration requires oxygen and releases carbon dioxide.
Oxygen is used by us and most other organisms for cellular respiration.
diaphragm
The diapragm is a largedome-shaped muscle that contracts rhythmically and continually.
When you inhale, the diaphragm contracts and flattens and the chest cavity enlarges.
The right lung is composed of three lobes, while the left lung is only comprised of two (smaller due to position of heart)
Pharynx
connects the nasal and oral cavities with the larynx and esophagus
Flap of tissue covers the top to prevent food from entering
Larynx
voice box
top part of the air-only pipe
vocal cords which vibrate to make sounds.
C-Shaped cartilage
Reinforce the sides of the trachea to protect and keep the airway open
This allows the trachea to collapse slightly to allow food to pass down the esophagus
Air enters
absorb oxygen into the bloodstream
and breathe out carbon dioxide
Air comes into the body through the nose or mouth
Airways are the tubes that carry air into our lungs.
Air enters
The nose helps warm, moisturize, and filter air entering the body before it reaches the lungs.
Digestive System
Mouth
Esophagus
Stomach
Duodenum
Small Intestine
Large Intestine
Rectum
Anus
1 more item...
Stores waste
Absorbs water
colon which has three sections:
Descending
Transverse
Ascending
Intestinal glands
end absorption of nutrients and minerals from food
receives bile and pancreatic juice to aid in digestion
5 sections include:
Ileum
Mesentery
Jejunum
Duodenum
greater omentum
The digestive system breaks down the food into molecules. The body converts this into energy through a chemical process called cellular respiration (ATP)
Cellular respiration requires glucose
Glucose comes from when the stomach digests food, the carbohydrates in the food break down into a sugar called glucose
The stomach and small intestines absorb the glucose and then release it into the bloodstream
Liver
Bile from liver helps digest fat
Pancreas
Pancreatic Juice
Creates enzymes such as amylase, tripsin, and lipase
Gastric glands
Hydocloric Acid
Secrets enzymes that digests food
Fundus
Longitundial, circular, and oblique muscles
When the stomach digests carbohydrates in the food, it break down into a sugar called glucose
Pharynx
muscular contractions help push food downwards (Peristalsis)
Salivary glands to produce amylase
Mouth
Teeth
Breaks down food
Tounge
