Tube that carries oxygen from the mouth to the Bronchi.
Bronchioles
Alveoli
Esophagus
Trachea
Which of the following statements is true?
Your lungs can store several hours' worth of oxygen.
Your body can't store oxygen at all.
Your body stores oxygen in your bloodstream.
Your body needs carbon dioxide to function properly.
What organ of the respiratory system is in blue.
pharynx
trachea
larynx
epiglottis
Cellular respiration uses glucose and __________ to make energy.
carbon dioxide
glucose
oxygen
mitochondria
If your epiglottis were to suddenly stop working, what activity could be life threatening?
Breathing
Walking
Coughing
Eating
What structure connects the larynx to the bronchi?
Pleura
Oropharynx
Trachea
Bronchioles
Specialized cells in the bronchioles have structures on them called
alveoli
cilia
dermacytes
erythrocytes
The exchange of oxygen and carbon dioxide in the alveoli is through a process called
active transport
conduction
convection
diffusion
Type of circulation that refers to blood flow from the heart to the lungs and back to the heart again?
Systemic circulation
Renal circulation
Portal circulation
Pulmonary circulation
Which choice below correctly identifies the layers of the heart from the most outer layer to the most inner layer?
epicardium, myocardium, endocardium
endocardium, myocardium, epicardium
myocardium, endocardium, epicardium
myocardium, epicardium, endocardium
Deoxygenated blood flow from the body cells to the heart via .....
Vena Cava
Aorta
Pulmonary artery
Pulmonary vein
The valves..
allow two way direction of blood in the heart
prevent back-flow of blood
prevent high pressure exerted in the vessels
allow lower pressure of blood flow in the heart
The right and left chambers are separated by
Sternum
Septum
Sernom
Strenoum
The myocardium is composed of:
An outer fibrous layer and an inner serous layer.
Cardiac muscle tissue.
A simple squamous epithelium and a layer of areolar connective tissue.
As their name implies, the heart chambers that receive
blood returning through both circulatory circuits are called:
Auricles
Atria
Ventricles
Sinuses
All of the following are true of the left ventricle except:
Wall is typically 3 times thicker than that of right ventricle.
It is separated from left atrium by Mitral valve.
Aortic semilunar valve at superior end separates it from the aorta.
Receives deoxygenated venous blood from the left atrium.
From the right atrium, blood passes through the right AV
(tricuspid) valve into the:
Pulmonary trunk.
Left atrium.
Right ventricle.
Left ventri.cle
Compared with those of the systemic circulation, arteries of the pulmonary circulation:
Have lower blood pressure.
Have less elastic tissue.
Carry blood that contains less oxygen.
All of them.
Blood is made up of
Plasma
Blood cells - red and white
Platelets
All of the above
