What is the effect of increased vessel length on blood flow?
The longer the vessel is the more friction it applies on the passing blood, the less the blood flow is.
Thin-walled blood vessels less elastic than arteries?
aorta
What is the difference between an artery and a vein and what do they do?
Arteries are more elastic but have smaller lumen. They carry blood away from the heart. Veins are less elastic have larger lumen and have valves. They carry blood to the heart.
What is the homonyms for useless and blood vessel?
The homonym for "useless" is "yous less," which sounds the same but has a different spelling and meaning. The homonym for "blood vessel" is "flood vessel," which also sounds the same but has a different spelling and refers to a vessel that carries fluids other than blood. Homonyms are words that sound the same but have different meanings and spellings.
What causes the transfer of materials between capillaries and tissue fluid?
As blood enters the capillary bed on the arteriole end, the blood pressure in the capillary vessel is greater than the osmotic pressure of the blood in the vessel. The net result is that fluid moves from the vessel to the body tissue.At the middle of the capillary bed, blood pressure in the vessel equals the osmotic pressure of the blood in the vessel. The net result is that fluid passes equally between the capillary vessel and the body tissue. Gasses, nutrients, and wastes are also exchanged at this point.On the venue end of the capillary bed, blood pressure in the vessel is less than the osmotic pressure of the blood in the vessel. The net result is that fluid, carbon dioxide and wastes are drawn from the body tissue into the capillary vessel.
Which blood vessel renal artery or renal vein contain less nitrogenous waste?
Renal vein.
Why do veins have less collagen elastic fibers and smooth muscles than arteries?
Because blood in veins is under lower pressure than in arteries, so they do not need as many collagen fibres. In addition, as veins already have a wide diameter, they do not need to dilate that much hence they also dont contract that much (as opposed to artieries), so they have less elastic recoil, thus they have less elastic fibres. :)
Do blood vessels increase in size to lose heat?
If a blood vessel has a larger diameter then there is an increased rate of blood flowing through that vessel per unit of time. This increased rate causes an increase in heat through the vessel. Thus constricting the diameter of the blood vessel will cause a decrease in the rate of blood flow, causing less heat and therefore increased heat loss.
What happens to people's blood pressure as they age?
As people age, their blood vessels tend to become stiffer and less elastic, leading to an increase in blood pressure. This is known as arterial stiffness. Additionally, the renin-angiotensin-aldosterone system, which helps regulate blood pressure, may become less efficient with age, contributing to higher blood pressure levels. Lifestyle factors such as diet, exercise, and stress management also play a significant role in blood pressure regulation as people age.
What are the signs and symptoms of high blood pressure?
The researchers think that the higher the pulse pressure, the stiffer the blood vessels. The stiffer the blood vessel, the less likely the nerve endings are working properly. If the nerve endings aren't functioning correctly, the less likely a person will feel pain.
What is the consequences for the umbilical cord not to have 3 vessel cords?
The feotus will get blood/nutrients less easily from mother as less vessels means a smaller flow of the babies vital nutrition. The extent of this however, depends on the stage of pregnancy, missing vessel and personal case - see doctor to seek advice
How do you use 'vessel' in a sentence?
Keep your vessel at five knots or less while in the channel.
