What is the difference between a respirometer and spirometer?
They r the same
Do divergent boundaries everoccur between continental and oceanic crust?
yes because why they r separate they r together
What is the relationship between time and space?
The relationship between time and space is, r=ct or space = the speed of light times time.Time t = r/c or time is space divided by the speed of light.Space r is a real number as time t and cthe speed of light.
What does the symbol r stands for in the universal law of gravitation?
r stands for the distance between the centres of the masses. Please see the link.
What is the difference between alanine and glycine amino acids?
The -r group of alanine is -CH3 - which is a non-polar group, while the -r group of glycine is -H - which is an uncharged polar r group.
Valves between the ventricles and blood vessels?
Pulmonary Semilunar Valve between R. Ventricle and Pulmonary Trunk. Aortic Valve between L. Ventricle and Ascending Aorta.
What are the four chambers of the heart i'n a diagram?
The 4 chambers in the eart are the left and right atria, and the left and right ventricle. Each chamber has one valve.
List the structures in the order blood would meet them during its travel through the heart?
sup. vena cava, R. atrium, tricuspid valve, R. ventricle, pulmonary valve, pulmonary artreys, lungs, pulmonary veins, L. atrium, mitral valve, L. ventricle, aortic valve, aorta, brachiocephalic artery
What does the P-Q or P-R interval give?
Finally, the P-Q or P-R interval gives a value for the time taken for the electrical impulse to travel from the atria to the ventricle (normally less than 0.2 seconds).
What does each side of the human heart do?
Mitral valveAlso known as the "bicuspid valve" contains two flaps. The mitral valve gets its name from the resemblance to a bishop's mitre (a type of hat). It allows the blood to flow from the left atrium into the left ventricle. It is on the left side of the heart and has two cusps.A common complication of rheumatic fever is thickening and stenosis of the mitral valve.Tricuspid valveThe tricuspid valve is the three-flapped valve on the right side of the heart, between the right atrium and the right ventricle which stops the backflow of blood between the two. It has three cusps.
Trace molecule of O2 from from nasal cavity into aorta?
nose - trachea- carina r/l bronchi- terminole bronchioles- respiratory bronchioles- alveolar sacs- pulmonary vein - lungs - inferior and superior vena cava- right atrium- atrioventricular valve- right ventricle- pulmonary sem-lunar valve- pulmonary trunk - left atrium- left ventricle- aortic valve-aorta
What is the function of the l and r ventricle?
The left ventricle pumps blood to the systemic circulation. The right ventricle pumps blood to the lungs.
What order does the circulatory system work?
r atrium r ventricle pulomanry artery lung capillaries pulmonary vein l atrium l ventricle aorta
Explain why in human beings oxygenated and deoygenated blood never mix.?
Saying that oxygenated anddeoxygenated blood never mix is a bit misleading. First lets start with the bodies pump, the heart. The heart is divided into four parts, the Left having two parts (L atria and L ventricle) and the Right having two parts (R atria and R ventricle). The Left side of the heart receives oxygenated blood from the lungs first in the L atrium and then into the L ventricle. The L ventricle pumps the blood to the rest of your body through arteries. It is at the level of the capillaries, tiny blood vessels, that oxygenated blood donates it's oxygen to tissue, and hence becomes de-oxygenated. This again is a little misleading because it is not devoid of oxygen, it just has much less oxygen than before the donation. After the donation of oxygen at the capillary the blood is now on the venous side and returns the de-oxygenated blood to the heart. This oxygen poor blood arrives on the R side of the heart in the R atrium and then the R ventricle where it is pumped to the lungs to become oxygenated and then returned to the L atrium and the cycle continues. There are however, disorders of the heart, (ie PDA), that allow de-oxygenated and oxygenated blood to mix in the heart. This leads to poorly oxygenated blood being delivered to tissues.
Trace the pathway of the blood as it flows from the left internal jugular vein to the right popliteal artery?
There are 5 major circulatory flow points in route to the popliteal artery. From the internal jugular vein proceeds the superior vena cava, right renal vein, inferior vena cava, femoral artery and final popliteal.
What is another name for a courtyard that is five letters long and the second and third letters are t and r respectively?
Atria
How does the cardiovascular system oxygenate blood by returning it to the lungs?
breathing in, expands the chest which in turn lowers the pressure in the thoracic cavity. The lower pressure causes air to fill the lungs, the same lower pressure cause the pressure in the right atria to be lower, allowing for more blood to flow in, increasing the venous input thus increasing the cardiac output of the heart.
