Term | Definition |
How many Systems do you have | 3 |
Where does the glucose come from? | Food |
Where does the oxygen come from? | Breathing |
What are the final products of cellular respiration? | CO2 H2O ATP |
In which organelle does this take place in our cells? | Mitochondria |
Name the system that starts with a D | Digestive System |
Name a system that starts with a C | Circulatory |
Name a system that starts with a R | Respiratory System |
Digestive system begins a the | Mouth |
What is Chemical Digestion | Salivary glands produce amylase which begins to break down sugars and starches |
What is Mechanical Digestion | teeth grind and break down food into smaller pieces. |
What is Esophagus | moves food from mouth to stomach using peristalsis |
What is the small intestine | Absorption of food molecules into the blood takes place here |
What is the Villi | Inner surface of small intestine heavily folded and lined with small finger like projections. |
What is the purpose of the Human Digestive System? | Converts food into simpler molecules that can be used by the cells of the body; absorbs food and eliminates waste. |
What is the stomach | Food combined with acids and enzymes; the stomach muscles squeeze and contract |
What is Chyme | Partially digested food |
What is Cardiac Sphincter | Ring of muscles at top of stomach to keep food inside |
What is pyloric Sphincter | Ring of muscle at bottom of stomach to keep food pushed into small intestines from re-entering stomach |
Large Intestines | absorbs water and compacts waste |
What is rectum/anus | Releases wastes outside the body |
What are the accessory organs to the Digestive system | Pancreas and Liver |
What is a pancreas | Produce insulin and glucagon to regulate blood sugar levels |
What is a liver | Produce bile, aids in the digestion of fat |
Where is bile stored | In a pouch under the liver, the gall bladder |
What is Glucose | a Primary source of energy for the body |
Constant supply of glucose should be maintained where? | the blood, but must be kept in balance so as not to damage cells. |
What are Hormones? | produced by pancreas, glucagon and insulin, help cells maintain homeostasis with regard to blood sugar. |
What is the purpose of the respiratory systems | provider o2 to the blood for cellular respiration in the cells and removes CO2, from the body |
How does the respiratory system exchange gas? | through the walls of the sacs of the lungs |
What does the Nasal Cavity (Nose) do? | Warms, filters, moistens air as it passes over mucous membrane. |
What does the Pharynx (throat) do? | Located where the passages from the nose ad mouth come together. |
What is Epiglottis? | Flap of elastic tissue that forms a lid over the opening of the trachea. |
What is the Larynx (Voice Box) is located ? | between the pharynx and the trachea |
What does the Larynx contain? | Two ligaments - vocal cords that produce sound when air moves through them. |
What is the Trachea (windpipe) | Tube through which air moves from the pharynx to the lungs |
What is a Diaphragm | Sheet of muscle below the lungs that separate the chest cavity (thorax) from the abdominal cavity. |
What does the Diaphram do? | It contracts and relaxes to help inflate and deflate the lungs. |
What is the internal Respiration ? | The process by which cells get energy from the breakdown of glucose in the presence of oxygen. |
When does internal respiration occur? | in the Mitochondria |
What is Bronchi | Two short tubes which direct air into right and left lungs. |
What is Bronchioles | Millions of smaller tubes that branch off each Bronchi |
What is Alveoli | Small Sacs found at the end of the bronchioles that are surrounded by capillaries |
What is Breathing? | the movement of the air into and out of the lungs. |
What is External Respiration? | The exchange of Oxygen and CO2 between the blood in the capillaries of the alveoli and the air. |
Where does the External Respiration occur | In the Lungs |
After food is broken down /digested, what system do the molecules diffuse to? | Circulatory |
After you take a breath, in to what system does the oxygen diffuse to? | Circulatory |
Human Circulatory System purpose is | To transport oxygen and nutrients to all the cells in the body and to take carbon dioxide and wastes away from the cells of the body. |
Human Circulatory System structure consist of ? | Heart and blood vessels |
What is the Heart? | Main organ that pumps blood |
What is the Blood vessels? | Tubes through which blood travels |
What is blood? | .Liquid including read and white blood cells and platelets |
What is plasma? | thick, yellowish liquid in which blood cells are suspended |
What is red blood cells? | Carry O2 and remove CO2 (Transported by the protein hemoglobin) |
What is white blood cells? | Help fight disease |
What is platelets? | Help form blood clots |
What are arteries? | Carry blood away from heart |
What are veins? | Carry blood toward heart |
What are capillaries ? | Smallest blood vessels; where exchange of nutrients and wastes takes place by diffusion. |
What do plasma do? | Liquid part of blood. A dilute solution of salts, glucose, amino acids vitamins, urea, proteins and fats. |
What does White Blood Cells do? | Involved in Immune system |
What does Platelets do ? | Involved in blood clotting |
What does Red Blood Cells do? | involved in carrying oxygen |
Open Circulatory System is | Blood is only partially contained within a system of blood vessels. |
What is Single Loop Circulation | Most single loop vertebrates use gills for respiration and forces blood around body in one direction. |
What is Double Loop Circulation | Located in vertebrates that uses lungs for respiration |
Closed Circulatory System | Heart or heart - like organ forces blood through vessels that extend throughout the body. |
What is First Loop? | Carries blood between heart and lungs. |
What is the Second Loop? | Carries blood between heart and body |
Nervous System | Maintains homeostasis by controlling and regulating all other parts of the body. |
Function of the Nervous System consists of | Sensory, Interpretation, and Response |
What is a Sensory? | Users receptors to gather information from all over the body. |
What is Interpretation? | the brain then processes the information into the possible responses |
What is Responses | Sends messages back through the system of nerve cells to control body parts. |
What is a Neurons? | The functional |
