Body Systems Review
| Question | Answer |
|---|---|
| Respiratory System | Exchanges gases in the lungs |
| Respiratory System functions | 1. Gets oxygen from air for body's cells (inhaling) 2. Gets rid of carbon dioxide waste from cells (exhaling) 3. Allows us to speak |
| Respiratory System structures | Nose/sinuses, Pharynx, Larynx, Trachea, Bronchi/Bronchioles, Lungs. |
| Nose/Sinuses | make air warm, moist, and clean (hairs/mucus) Sinuses affect your voice. |
| Pharynx | (throat) Both food & air pass. Epiglottis keeps you from choking. |
| Larynx | (Vocal cords) |
| Trachea | windpipe. |
| Bronchi/Bronchioles | Smaller passages that split heading into the lungs |
| Lungs | Spongey organs filled with Alveoli |
| Alveoli | Tiny air sacs with two jobs: 1. Stuff O2 into capillaries 2. allow O2 into bronchioles. |
| Respiratory Disorders | Bronchitis, Asthma, Cystic Fibrosis |
| Bronchitis | Irritation of bronchia passage causing coughing |
| Cystic Fibrosis | Build-up of mucus in the lungs. Mucus must be loosened and coughed up very often |
| Asthma | Bronchial passages inflame, shrinking up and making breathing difficult |
| Respiratory System Homeostasis | By maintaining the proper amounts of oxygen and carbon in your blood |
| Respiratory System Stimulus | Tiring muscles while exercising |
| Respiratory System Reponse | Faster breathing rate to supply more oxygen to muscles |
| Circulatory System | Network of heart and vessels moving blood through the body |
| Circulatory System Functions | 1. Carries nutrients to cells from digested food 2. Carries oxygen to cells from inhaled air 3. Carries wastes from cells to kidneys and lungs 4. Fights diseases |
| Circulatory System structures | Heart, blood, arteries, veins, capillaries |
| Blood vessels | Lined with smooth muscles, ability to change thickness |
| Artery | Carries blood away from the heart |
| Vein | Carries blood back to the heart |
| Capillary | Tiny vessel that connects arteries to veins. Gasses, nutrients, and wastes are exchanged with cells in these |
| Blood | Made up of different cells & tissues |
| Plasma | Yellowish clear liquid part of blood |
| Platelets | Blood cells that clump together to make a clot |
| Circulatory System disorders | Atherosclerosis, Hypertension, Heart Attack |
| Atherosclerosis | Fat clogs inside your arteries |
| Hypertension | (high blood pressure), heart works too hard |
| Heart attack | Arteries feeding oxygen and nutrients to the heart gets blocked |
| Red blood cells | carry oxygen to other blood cells |
| White blood cells | Fight germs & eat dead body cells |
| Chambers | Left Artium, Left Ventrical, Right Atrium, Right Ventrical |
| Left Atrium | Recieves high O2 blood from lungs |
| Left Ventrical | Pumps high O2 blood to body |
| Right Atrium | Recieves low O2 blood from body |
| Right Atrium | Pumps low O2 blood to lungs |
| Heart | Made of cardiac muscle |
| Cellular Respiration | Gluctose + O2 → water(waste) + CO2(waste) + Energy |
| Breathing | The diaphragm muscle pulls down on the lungs, which creates a "vaccum" |
| 4 components of blood | Palsma, platelets, white blood cells, red blood cells |
| What can cause high blood pressure? | Arteries get clogged with fat |
| What can cause low blood pressure? | Broken blood vessel in body (internal bleeding) |
