What is called a tiny vessel?
The smallest vessels in the human body are capillaries. They are the blood vessels that absorb oxygen into the blood and returning blood cells that lack oxygen back into the heart and lungs to be oxidised.
Are lymphatic capillaries permeable to proteins?
Lymphatic capillaries are dead-end vessels interspersed between the vascular capillaries. They lack tight junctions between endothelial cells and therefore are more permeable to proteins than are vascular capillaries.
What is the definition of gangrene?
death of tissue: local death and decay of soft tissues of the body as a result of lack of blood to the area
What are causes muscle tightness through out body?
Lack of magnesium in the diet, poor posture, lack of flexibility, lack of stretching, dehydration, poor body biomechanics
What animal are totally blind?
A number of cave dwelling fish and amphibians lack pigment and are blind.
What causes dehydration like Lack of Vitamin C or Lack of fluid in body or Not enough dairy products?
Go with answer B. Lack of fluid in the body will cause dehydration.
Capillaries are very tiny how does this help them perform their function?
the size limits the ammount of blood that get to various organs or parts to the body so there size is good a regulating how much O2 they absorb as in the lungs or how mych blood flows to a certain place depending on need. need for blood and its components, need for body heat or lack there of. are a few
What are two physiological advantages of red blood cell structure?
There shape confers them a degree of flexibility as some capillaries are smaller than the diameter of a RBC. Secondly, the biconcave shape of the RBC gives it an ideal surface area to volume ratio for maximum gas exchange.
Why do doctors have to have the lack of any need to judge others?
Judjment is subjective. Doctors need to be totally objective.
What is definition of lack of infrastructure?
The lack of the fundamental facilities and systems serving a country or area
What is the lack of the ability of the body to carry oxygen may be due to a deficiency?
A lack of the ability of the body to carry oxygen may be due to a deficiency in
Effect of ischemia on cells?
Cellular ischemia occurs when perfusion (oxygenation of the body and tissues) decreases. Because of the lack of blood flow through the capillaries the metabolism goes from aerobic (with oxygen) to anaerobic (without oxygen) which causes metabolic acidosis. The blood stagnates in the capillaries and lactic acid builds up due to the pre-capillary sphincter relaxing. Also the vasomotor center fails and the carbon dioxide level increases. Because the post-capillary sphincters stay constricted the capillaries are enlarged with fluid. On and on the end result is a drop in cardiac output.
