Blood
Blood is a bodily fluid consisting of plasma, blood cells, and platelets that is circulated by the heart through the vertebrate vascular system, carrying oxygen and nutrients to and waste materials away from all body tissues. In many species, it also carries hormones and disease-fighting substances. In this category, you will find questions about the blood in your body, including blood types, blood diseases, and the function of blood.

Why transfusion fluids are made isotonic with blood plasma?
Expand blood volume to help a fluid deficit. Isotonic is used because they don't move water in or out of the cell- meaning they are most compatible with human blood as opposed to hypertonic and hypotonic solutions.
What does the blood provide to the body?
heart is a pumping organ of body whcih pumps oxygenated blood from lungs to the body part and dexoygenated blood from different body parts to lungs
coumadin ( oral) and heparin or lovenox ( both given by subcutaneous injection).
Also, a very popular blood thinner is the aspirin 80 mg or 81 mg, also known as asaphen E.C. 80 mg, A.S.A. tablets, or "baby aspirin".
Why do we separate plasma from blood?
Most of the time when you get your blood drawn you will notice they do so by filling up a small vial or sometimes a couple. This vial is put into a centrifuge (a machine that spins the vials very fast) to separate three main components in ones blood. Platelets, red/white blood cells, and plasma separate in the centrifuge and all can be extracted purely.
A crude example of a centrifuge would be your washing machine on the spin cycle pulling the water out of your clothes. Imagine this on a smaller scale with a vial of blood. The force causes the plasma to separate.
What are the non cellular portion of the blood?
Basic breakdown for use in transfusion is red cells, plasma, and platelets...however plasma is not a cellular component.
Three cellular components may be red cells, white cells, and platelets.
Maybe if you could elaborate on the question, it could be better answered.
What is the fluid portion of the circulatory system?
Our circulatory system is probably considered the highway of our body. It is responsible for moving blood cells, nutrients, hormones, waste products and blood gasses around you and distributing it to the organs in need.
What are the normal values for MPV?
Normal mean platelet volume is 7.5-11.5 femtolitre (1 femtolitre = 1 cubic micrometer). New platelets are bigger than older ones. Mor information on MPV blood test result in the link provided below.
What are the three types of bleeding?
1. Venous bleeding (bleeding from the veins). 2. Arterial bleeding (bleeding from the arteries). 3. Capillary bleeding.
How does gas travel in our bodies?
The gas is formed during the digestion of food and liquid in the intestine and bowel.
What is sudden increase in the number of white blood cell?
An abnormally high white blood cell count is known as leukocytosis. The opposite is leukocytopenia.
What is the normal hemoglobin range for adult females?
The normal range of hemoglobin in female is 12 to 16gm/dl (gram per deciliter).
And for a pregnant woman 11 to 12g/dl (gram per deciliter) is the normal range of hemoglobin.
Hemoglobin levels are often measured in grammes per decilitre (g/dl). 'Normal' levels are considered to be
* Women: 12.1 to 15.1 g/dl * Pregnant women: 11 to 12 g/dl * Out of interest: Men: 13.5 to 16.5 g/dl See Related Link
What gets filtered through the urinary system?
in a machine your pee but in your bladder citric acid, all other acids you have intaken, and what you just drank
Where in the body do erythrocytes originate?
They are made in the red marrow of long bones. The red marrow makes white blood cells and platelets as well. RBCs live for only 120 days.
What is the hormone that kidneys will secrete to stimulate red blood cell production?
Erythropoetin from the mesangial cells of the glomerulus in the nephron of the kidney. These cells detect altered levels of oxygen in the blood plasma.
What is the normal fasting blood glucose range in a diabetic teenager?
"Normal" is relative. It depends on a variety of factors, including whether or not they are diabetic, what point they feel "low", how well they manage their diabetes, medications and conditions, and hormones.
An average range is 80-120.
What is the reason for low ESR in blood?
A high erochite sedimentation rate indicates that you have some sort of inflammation in your system. The higher the rate the worse the inflammation. Inflammation is what happens when you immune system is reacting to something in your body. The test does not tell you what the reason for the inflammation is. it is often used in the case of rheumatoid arthritis to check on the activity of the disease. It can however also be brought up by any infection.
Can a rh positive father have a rhs negative baby?
Yes, it is possible. There are two genetic alleles that together determine whether a person is Rh positive or negative. It is the combination of these alleles within the parents that determine the child's Rh status.
In this case, both mother and father are positive so their alleles can only be ++ or +-.
The possible combinations are determined by taking one allele from one parent and combining it with an allele of the other until all combinations are made. Positive is the dominant allele so combinations of ++ and +- are considered Rh positive whereas -- combinations are negative.
The possible combinations are:
++ which would be an Rh positive baby
+- which would be an Rh positive baby
-- which would be an Rh negative baby
So yes, it is possible.
The pro-time (PT) has traditionally been used. Currently, variations in the reagents used to conduct the test are corrected by using a math formula and are expressed as an international normalized ratio (INR).
What happen when there is too much of glucose in the blood?
normal is about 70-90
at about 500 the patient loses consciouness.
at about 40 the patient goes into a coma
at about 20 there is brain damage
at about 10 the brain dies.
What can affect enzyme activity?
pH
Temperature
Substrate Concentration
non-ideal conditions will ultimately lead to the denaturing of the enzyme
