General
These cells help fight infection and disease
White Blood Cells
The first place digestion starts.
Mouth
These carry oxygen throughout the body
Red blood cells
Passage way that moistens the air and has hairs to trap dust and particles.
Nasal cavitiy
Glucose or Fructose
Muscle movement that pushes food through the digestive system.
Peristalsis
In this tube you will find the solids remaining, after food nutrients are absorbed into the blood stream.
Large intestine
The liquidy portion of blood.
Plasma
The muscle responsible for expanding and contracting the lungs.
Diaphragm
These are found primarily in meats and eggs.
Lipids
When your esophageal sphincter doesn't close properly, this happens.
Acid reflux
This lines the stomach and allows it to expand.
Rugae
The name of the bottom chambers in the heart.
Left and right ventricle
This is the tube between the larynx and bronchi.
Trachea
Name the 4 macromolecules
Lipids, Carbohydrates, proteins and nucleic acids
How does your body know when to respire (breathe)?
The brain (medulla)!
Too much CO2 concentration in the body sends a signal.
This location in the small intestine takes enzymes from the accessory organs.
Duodenum
The blood vessel where diffusion of O2 and CO2 occurs.
Capillaries
These are empty chambers where gas exchange occurs.
Alveoli
Importance of lipids
Long term energy storage
Insulation & cushion
Vitamin absorbance
Describe how the circulatory and digestive system work together.
Capillaries attached to small intestine cells
Villi in small intestine have capillaries
Nutrients move across membrane into capillaries
Capillaries carry nutrients to veins - around body
The location where MOST absorption of nutrients takes place.
Small intestine
Describe how the respiratory and circulatory system work together.
Body takes in O2 (mouth/nose > trachea > bronchi > bronchioles > alveoli sacs)
O2 diffuses across membrane (b/c low O2 in RBC)
Blood moves through capillaries to heart
Heart pumps blood throughout body (arteries > capillaries > veins)
Veins bring blood back to heart, gets pumped to lungs
The type of respiration between cells and capillaries is called this.
Internal respiration
Structural: Muscle, bones, hair, skin
Enzymes: Saliva, gastric juices
Hormones: Testosterone, estrogen, insulin, adrenaline
