Resp-Circ Systems
Respiratory & Circulatory System
| Question | Answer |
|---|---|
| When blood leaves the right atrium where does it go? | Right Ventricle |
| Which side of the heart contains oxygenated blood? | Left |
| Which vessels carry blood away from the heart? To the heart? | Arteries. Veins. |
| Where does gas exchange occur in the lungs? | Alveoli |
| What keeps food from going down the trachea? | Epiglottis |
| What part of the blood is responsible for healing? | White blood cells |
| What part of the blood is responsible for clotting? | Platelets |
| What is the primary goal of cellular respiration? To provide what to our body? | To break down sugar in the presence of oxygen to produce ATP (energy) |
| What is the wall that separates the two sides of the heart? | septum |
| What is another name for windpipe? | trachea |
| What creates pressure to pump blood to the body? | heart |
| Where, specifically, is hemoglobin found and what does it do? | In red blood cells- it transports the oxygen |
| Where are the vocal cords? | Larynx |
| Your heart makes a lub-dub sound, what causes this? | Valves closing - This prevents the backflow of blood |
| When blood leaves the lungs, it is (oxygenated or deoxygenated) blood. How does it re-enter the heart? | Oxygenated. Through the pulmonary vein |
| What is the largest artery in the body? | aorta |
| What is the function of the respiratory system? | To take in oxygen and remove carbon dioxide |
| What are the functions of the circulatory system? | 1. Picks up oxygen from the lungs and nutrients from the digestive system and carries them to the body 2. Carries waste products to where they can be eliminated 3. Helps fight disease and injury by carrying the substances that will heal you. |
| Is it better to breathe through the nose or mouth? Explain. | The nose is lined with mucus and cilia which can trap dust particles. It also warms the air before it enters the lungs |
| What is the equation for cellular respiration? | O2 + C6H12O6 CO2 + H2O + ATP Oxygen + Glucose carbon dioxide + water + ATP |
| What are the 2 muscles that are involved in breathing? | Diaphragm and Intercostals |
| What are the vessels where gas and nutrient exchange occur? Why is this able to happen so easily in these vessels? | Capillaries. They are only 1 cell thick. |
| What is your pulse? Why does it increase during exercise? | It is the bulge of the artery that occurs each time your heart pumps out the blood. It is a reflection of your heart beat. It increases with exercise in order to deliver more oxygen and nutrients to the muscles. |
| Explain how the circulatory and respiratory systems work together in order for cellular respiration to occur? | Respiratory system takes oxygen and delivers to circulatory system. Circulatory system takes oxygen, along with nutrients from digestive system, to cells to be used in cellular respiration. CO2 waste is taken back to the lungs by blood and it is exhaled. |
| What are the possible blood types a person can have? | A, B, AB, 0 |
| What are 4 factors leading to cardiovascular problems? | Stress, Inactivity, Poor Diet, Smoking, Heredity |
| List and describe 3 cardiovascular problems. | High Blood Pressure (Hypertension) Heart Attack Atherosclerosis |
| Why do you need to eat and breathe? | You need to take in the nutrients and oxygen that your cells need to make ATP (energy) during cellular respiration. |
