Circulatory system 2
circulatory system
| Question | Answer |
|---|---|
| The Circulatory System consists of: | Arteries, Veins, Vessels, and Heart |
| What are the 2 sub systems the circulatory system is devided into? | Cardiovascular and Lymph |
| The part of the cardiovascular system where blood is circulated through the heart, to the lungs and back to the heart is called? | Pulmonary |
| The part of the cardiovascular system where blood is circulated through the entire body(except the lungs) is called? | systemic |
| Discribe what is happening when blood is transported through the lungs | The blood becomes oxygenated and rids of Co2 |
| The largest artery of the body is the | Aorta |
| The purpose of valves is to | Allow blood to fow in one direction |
| List some functions of blood: | Carry H2O, ogygen, & food secretions to body cells, carry Co2 away and protect body from harmfull bacteria and equalize temperature. |
| Veins carry what tye of blood? | deoxygenated |
| Arteries carry what type of blood? | Oxygenated |
| Which chambers of the heart have thin walls? | veins |
| Which chambers of the heart have thick walls? | arteries |
| What is the name of the cavity in which the heart lies | chest |
| The normal temperature of the human body is approximatly______? | 37 degrees celcius |
| What componant is NOT present in tissue fluid? | Red Blood Cells |
| What chemical is NOT transported in the liqjuid part of the blod? | Fibrin |
| The percentage of water in the blood plasma is | 90% |
| Which component of blood transports oxygen? | Erythrocytes |
| Which is NOT a component of human blood? | Fibroblasts |
| The cells responsible for the defence of the body are: | white blood cells |
| The blood cells which do not have a nucleus are:? | erythrocytes |
| Blood cells are formed in the:? | bones |
| The destruction of red blood cells are made in the:? | liver |
| After birth, red blood cells are made in the:? | bone marrow |
| Which mineral is used to produce haemoglobin:? | iron |
| The function of white blood cells is to:? | destroy bacteria |
| The name of the substances which stimulate the production of anit-bodies in the blood is called:? | antigens |
| The component of blod responsible for the manufacture of antibodies is:? | lymphocytes |
| the substances produced in the body which destroy or neutralize foreign substances are called | antibodies |
| defence against antigens des not take place by | erythrocytes |
| the component of blood mostly concerned with the control of infection is | white blood cells |
| The component of blod which plays an important role in clotting is | platelets |
| the primary function of thromocytes is to | play a role in blood clotting |
| what vitamin causes an increase in clotting time of blood when it is deficient | K |
| when blood clots, the soluble substance which becomes insoluble is called | fibrinogen |
| calcium in the blood is necessary for | blood coagulation |
| deoxygenated blood enters the heart by the | right atrium |
| the name of the cavity in which th heart lies is called | pericardial cavity |
| When the ventricles of the heart contract the | aortic and pulmonary valves open |
| blood is prevented from returning to the ventricles after they have completed their contractions by the | semilunar valves |
| what chamber of the heart pumps blood to the lungs? | right ventricle |
| the average rate of the heart beat of a healthy adult in rest in number of beats per minute is | 70 |
| the right ventricle and the left atrium are connected by the | pulmonary circulation |
| the blood vessel that collects blood from the digestive organs is the | hepatic portal vein |
| The blood vessel which has thick muscular walls and carries de-oxygenated blood is the | pulmonary artery |
| the right ventricle of the heart | is the beginning of the pulmonary circulation |
| after leaving the rigt ventricle, blood is pumped to the | Pulmonary artery |
| The characteristic the CANNOT be applied to veins is that they | always carry blood away from the heart |
| the INCORRECT statement about arteries is that they | have valves |
| a characteristic of ALL arteries (except pulmonary arteries) is that they | transport blood rich in oxygen |
| arteries | have an elastic wall |
| the muscle tissure located whiin the walls of blood vessels is | smooth muscle tissue |
| the extremely thin walls of capillaries are made of | only endothelium |
| tissue fluid leaves the capillaries by | diffusion |
| the function of capillaries is NOT for the purpose of the | destruction of antigens |
| the lymphatic vessel that gathers most of the lymph is the | thoracic duct |
| the liquid which carries dissolved substances from capillaries to cells and back is | tissue fluid |
| macrophages and lymphocytes that filter lymph are situated in the | lymph nodes |
| fat is transported through the circulatory system by | lymph |
| The fluid between the cells is driven along by: | pressure from the contracting muscles around them |
| the location of the spleen is | to the left of the body under the diaphragm |
| after leaving the left ventricle, blood flows from the heart to the | aorta |
| the name of the vessel taking blood from the stomach to the liver is called the | hepatic portal vein |
| the blood vessel which discharges into the right atrium is the | inferior vena cava |
| the blood vessel NOT connected to the liver is the | inferior vena cava |
| blood is carried to the liver through the | hepatic artery and hepatic portal vein |
| the name of the vessel that takes blood from the liver to the vena cava is the | hepatic vein |
