|
What is the function of the circulatory system?
|
The function of the circulatory system is to pump blood through the body
|
|
|
Which organs make up the circulatory system?
|
The HEART, LUNGS, VEINS, ARTERIES and CAPILLARIES
|
|
|
What role does blood play in carrying oxygen to the cells?
|
The red blood cells carry mitochondria and carry's oxygen to the cells.
|
|
|
What would happen if a clot occurred in a major artery?
|
A stroke or heart attack would happen. Maybe death.
|
|
|
What is the pathway of blood through the heart?
|
Blood returning from the body circulation enters the right atrium. From there, blood flows into the right ventricle, which then pumps blood to the lungs. Blood returning from the lungs enters the left atrium, then the left ventricle. The left ventricle then pumps blood to the rest of the body via the aorta.

|
After eating a slice of pizza which path does the food take through your digestive system?
|
Mouth. Esophagus, Stomach, Small intestines, Colon (large intestines), Rectum, Anus
|
|
|
What is the function of the digestive system?
|
Process of food and absorbing the nutrients and water
|
|
|
What are the functions of all the organs in the Digestive System?
|
Mouth-to tear and grind food, mechanical digestion
Esophagus- swallowing pushes food into esophagus, a passageway to the stomach Stomach- squeezes, sloshes, and mixes food Small Intestine- chemical substances break down Large intestine- The last step of digestion is called absorption. It occurs when nutrients pass through the wall of the small intestine and enters the circulatory system. Only waste remains in the small intestine after absorption occurs. They enter the large intestine where water is removed from the wastes and returned back into the body. Rectum and Anus- Waste products are moved through an opening called the Anus. |
|
|
What is the function of the epiglottis?
|
It protects the airway during swallowing
|
|
|
What is the function of the respiratory system?
|
To supply the body with oxygen and remove carbon dioxide.
|
|
|
Which organs make up the respiratory system?
|
nose, throat, lungs, and passageways that lead to the lungs
|
|
|
What wastes product does the respiratory system remove?
|
Carbon Dioxide
|
|
|
What is the “formula” for creating energy in the cell?
|
Cellular Reproduction
|
|
|
How does the diaphragm move\ during an inhale and exhale.
|
When you inhale, your diaphragm contracts and moves down, make more space in your chest. When you exhale, your diaphragm relax and move up, squeeze the carbon dioxide out if your body.
|
|
|
What is cellular respiration? Where does cellular respiration take place?
|
Cellular Respiration, process in which cells produce the energy they need to survive. (Oxygen+Glucose)
|
|
|
Which part of the lungs does gas exchange occur between the respiratory and circulatory systems?
|
gas exchange occurs in the lungs and the circulatory system then transports the oxygen to tissues that used internal respiration to burn fuel for energy, creating more carbon dioxide.
|
|
|
Be able to label the respiratory system and the digestive system, and the circulatory system.
|
The mouth is the opening through which food is ingested. The esophagus is another channel through which food passes on the way to the stomach. The stomach stores food and is the primary site of chemical digestion. Following digestion in the stomach where food is broken down with acid, the food passes into the small intestine. Nutrients are absorbed via the intestine. Much shorter than the small intestine, though greater in diameter, is the large intestine.
|
|
|
Know the function of the major organs of all 3 systems
|
The mouth and nose enable you to breathe in oxygen.
The pharynx is your throat, and connects the mouth to the trachea. The larynx is you voice box... |
|
|
Where are most of the nutrients absorbed in the digestive system? Water?
|
The small intestines. Water is absorbed in the colon.
|
|
|
Where does chemical digestion take place? Mechanical digestion? Why do we need both to work together?
|
Chemical digestion takes place in the small intestines. Mechanical digestion in the mouth, during chewing. And in the stomach.
|
|
|
What is peristalsis and where does it occur?
|
Muscles in the digestive system that helps the mechanical digestion by squeezing and pushing the food along. It happens in the espohagus
|
|
|
Which organs do the respiratory and digestive systems share?
|
The pharynx.
|
|
|
Lung problems, such as asthma, keep the body from functioning at best levels. Explain why.
|
It affects the lungs by inflaming the linings of the bronchioles, making it harder to breathe and creating the 'wheezing' sound.
|
|
|
What are the 12 body systems that make up our bodies? What are the major organs? What are the functions of these systems?
|
Cardiovascular system: the blood circulation with heart, arteries and veins
Digestive system: processing food with mouth, esophagus, stomach and intestines. Endocrine system: communicating within the body using hormones Excretory system: eliminating wastes from the body Immune system: defending against disease-causing agents Integumentary system: skin, hair and nails Lymphatic system Muscular system: moving the body with muscles Nervous system: collecting, transferring and processing information with brain and nerves Reproductive system: the sex organs Respiratory system: the organs used for breathing, the lungs Skeletal system: structural support and protection through bones |
|
|
What is homeostasis?
|
homeostasis is the maintaining a well balanced internal condition. For example, we sweat to cool off during the hot summer days, and we shiver to produce heat during the cold winter season.
|
|
|
How is the human body organized from the SMALLEST LIVING UNIT to the LARGEST.
|
Cells -> Tissues -> Organs -> Organ systems -> Organism
