Question | Answer |
carries some oxygen through blood | plasma |
these are red blood cells | erythrocytes |
not having enough red blood cells means you are this.. | anemic |
iron in your blood is called this | hemoglobin |
platelets that help blood clot when you get an injury | thrombocytes |
another name for white blood cells that fight infections | leukocytes |
this type of circulation pumps blood to the left side of the heart to the body tissue | systemic circulation |
this type of circulation pumps blood to the right side of the heart and lungs | pulmonary circulation |
this blood is mixed and largely oxygenated | capillary blood |
why do arteries need to be thicker | to take the force of the pumping of the blood from the heart. |
another name for small arteries | arterioles |
another name for small veins | venules |
smallest veins | capillaries |
how big the largest arteries are | size of fingers or thumb |
these have thicker walls then veins carry blood away from the heart | arteries |
these have thicker walls then capillaries carries blood to the heart | veins |
these are in veins that help blood go in and out of the arteries like (lift stations) | valves |
older veins that collect blood because the valves aren't opening and closing as well most of feet can be found on runners | varicose veins |
area between lungs | mediastinum |
this nerve goes to the heart and effects heart rate, increasing and decreasing like when working out | vagus nerve |
this nerve stretches across your diaphragm and contracts involuntarily | phrenic nerve |
inner lining of the heart | endocardium |
heart muscle | myocardium |
3 pericardium's | visceral, cavity, fibrous pericardium |
refers to organs such as the heart | visceral |
hole space, that goes around the heart with fluids | cavity |
fibrous and fatty and strongly attached to the sternum and keeps twisting contracting and squeezing the heart. | fibrous pericardium |
infections of the layers of the heart | pericarditis |
sends out pulse to the heart | SAS (sinal atrial node) |
travels to the ventricle | AV (atrioventricular node) |
ECG | electrocardiogram |
120 or normal blood pressure that is always higher and in top( during ventricular contraction) | systole |
80 or when your relaxed is lower.(during ventricular relaxation) | diastole |
high blood pressure | hypertension |
chest pain | angina |
angina is cured with | nitroglycerin |
when your heart stops | cardiac arrest |
blockage of arteries | myocardial infraction |
quiver heart beat electrical activity | v-fibrillations |
stops all unorganized electrical activity , stops heart | d-fibrillations |
atrioles quiver | atrial-fibrillations |
causes atrium to compact | P-wave |
big spike causes ventricles to contract | QRS |
repolarization "resetting" | T-wave |
how long and short they are can help tell if you will go into cardiac arrest | P-Q and S-T segments |
heart beat is know as this | sinus rhythm |
route of blood supply being blocked you can get this surgery | bypass surgery |
looks strait back into the pharynx | oral cavity |
air and food goes through this | pharynx |
breaks down and digests food | stomach |
tree parts of the small intestine | duodenum, jejunum, ileum |
what does the small intestine do | absorption |
2 parts of the large intestine | cecum, vermiform appendix |
what the large intestine does | removes absorbed water |
carries stuff up through the large intestine | ascending colon |
carries stuff across the large intestine | transverse colon |
carries stuff down the large intestine | descending colon |
carries stuff to the bottom of the large intestine | sigmoid colon |
temporary storage for waste | rectum |
composed of sphincter muscles | anal canal |
help break down food to go through mouth | teeth |
pushes saliva and food down the esophagus | tongue |
produces saliva to digest food centrally located | sublingual |
produces saliva to digest food under tongue | submandibular |
produces saliva to digest food located on top of mouth | parotid |
takes out parasites, produces bile, filters blood(largest internal organ) | liver |
under liver, stress and concentrates bile | gallbladder |
collects bile and spreads it around the body where needed | bile ducts |
deep to stomach, produces insulin for digestive material. | pancreas |
connects pharynx to stomach | esophagus |
