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.

What is the ratio of packed cell volume to hemoglobin for male and female?

User Avatar

Asked by Wiki User

The Packed Cell Volume (PCV), or hematocrit, shows the proportion of blood volume filled by red blood cells, carrying oxygen through hemoglobin. Typically, there's a 3:1 ratio of PCV to hemoglobin. Gender differences in this ratio are minor, though slight variations exist due to physiological disparities.

PCV to hemoglobin ratio serves as a crucial indicator of blood's oxygen-carrying capacity, aiding in clinical assessments of blood disorders and anemia. Healthcare professionals can provide insights through PCV tests, crucial for uncovering underlying health issues. Medicas providingPacked Cell Volume (PCV) test, designed to offer a holistic approach. Further aslo evaluating the necessary to find out underlying health issues.

How many pints of blood does a fifty pound dog have and how many would it have to lose to lose consciousness or die?

User Avatar

Asked by Wiki User

quote from wikipedia: Guyton's Textbook of Medical Physiology states that "the total amount of water in a man of average weight (70 kilograms) is approximately 40 liters, averaging 57 percent of his total body weight

see link:

Assuming that humans and dogs have about the same water by weight percentage, a 50 lb dog would have 28.5 lbs of water in his body. Also I think it safe to assume that the water to blood correlation is pretty close to 1:1 as well.

Converting 70kg to pounds gives: 70kg*2.2lbs/kg=154lbs

Converting 40 liters to pints gives: 40L*1.76pints/L=70.4pints UK

So if there are 70.4pints UK per 154lbs how many pints UK per 50lbs?

70.4/154=x/50

solve for x gives 22.86 pints UK of blood in a 50lbs dog.

Fatal blood is between 30-40% fainting would be anything less than this and dependent on a whole lot of another factors.

I am Wolfgang Schwartzschild.

Hopefully this will give you some insight so I don't just get a "take your dog to the vet" comment.

I am writing a book in which one of the characters can shapeshift into a 50 lb dog. She has had her foreleg gored by a boar and the radial artery and cephalic vein have been severed. She has lost consciousness due to blood loss. Another character has found her and had given her a tourniquet. I know that the limb will eventually be lost because of this, but right now I am concerned about the amount of blood a dog has and how much it can lose before losing consciousness or dying.

Please don't just give me a "why arr you asking this about your dog?" comment. She is not my dog. She is a character in a sci-fi novel that is being worked on.

If your answer is sufficient it is very likely that I will try to incorporate your name into the book as a way of thanks.

Thank you for your time.

What is the erythrocyte sedimentation rate?

User Avatar

Asked by Wiki User

The erythrocyte sedimentation rate (ESR) is a blood test that measures how quickly red blood cells settle at the bottom of a test tube. It is a non-specific marker of inflammation in the body and can be elevated in various conditions, such as infections, autoimmune diseases, and cancer. A high ESR typically indicates the presence of inflammation, but further tests are needed to determine the underlying cause.

What does absolute eosinophils means?

User Avatar

Asked by Wiki User

Absolute eosinophils refers to the actual number of eosinophils present in a sample of blood, typically measured as part of a complete blood count (CBC) test. Eosinophils are a type of white blood cell that plays a role in the body's immune response, particularly in fighting off parasitic infections and allergic reactions. An increase in absolute eosinophil count may indicate various conditions, including allergies, asthma, parasitic infections, autoimmune diseases, and certain types of cancers. Conversely, a decrease in absolute eosinophil count may be associated with certain types of infections or bone marrow disorders.

If you're concerned about your Absolute Eosinophil counts or any other aspect of your health, it's essential to consult a qualified healthcare professional. Medicas offers Absolute Eosinophil count tests as part of comprehensive diagnostic services.

What test measurs percentage by volume of packed red blood cells in a whole blood sample?

User Avatar

Asked by Wiki User

In addition to hematocrit, another key blood parameter often measured is hemoglobin concentration, which represents the amount of oxygen-carrying protein within the red blood cells. Hemoglobin and hematocrit are closely related and provide complementary information about the blood's oxygen-carrying capacity and overall health status.

Hematocrit values can vary depending on factors such as age, sex, altitude, and certain medical conditions. For instance, low hematocrit levels may indicate anemia, blood loss, or nutritional deficiencies, while high levels could suggest dehydration, polycythemia vera, or other underlying health issues.

Interpreting hematocrit results typically involves consideration of the patient's medical history, symptoms, and other laboratory findings to guide diagnosis and treatment decisions. In clinical practice, Medicas are providing packed cell volume (pcv)test, for measuring the routinely performed as part of a complete blood count (CBC) test to assess various aspects of blood composition and function.

What are regulatory functions of blood?

User Avatar

Asked by Wiki User

Blood plays crucial regulatory functions in the body, helping maintain homeostasis and supporting various physiological processes. Some of the key regulatory functions of blood include:

Transportation of Oxygen and Nutrients: Blood carries oxygen from the lungs to cells and tissues and transports nutrients, such as glucose and amino acids, from the digestive system to cells for energy and growth.

Removal of Waste Products: Blood transports waste products, such as carbon dioxide and urea, from cells and tissues to the lungs and kidneys for elimination from the body.

pH Regulation: Blood helps regulate the body's pH by carrying buffers that minimize changes in acidity or alkalinity. This is crucial for maintaining the proper pH environment for enzymatic and metabolic processes.

Temperature Regulation: Blood helps regulate body temperature by absorbing and distributing heat. It carries heat away from active areas, such as muscles, to cooler areas and plays a role in temperature homeostasis.

Fluid Balance: Blood helps maintain fluid balance in the body by distributing water between cells and the extracellular fluid, ensuring proper hydration and preventing excessive fluid loss or accumulation.

Immune Response: Blood contains white blood cells (leukocytes) and antibodies that contribute to the body's immune response. They help defend against infections, pathogens, and foreign substances.

Clotting and Hemostasis: Platelets and clotting factors in the blood play a vital role in preventing excessive bleeding and promoting wound healing. The clotting process, known as hemostasis, helps control bleeding and maintain vascular integrity.

Hormone Transportation: Blood carries hormones from endocrine glands to target cells or organs, facilitating communication between different parts of the body and regulating various physiological processes.

Electrolyte Balance: Blood helps maintain the balance of electrolytes, including sodium, potassium, calcium, and others, which are essential for proper cellular function, nerve transmission, and muscle contraction.

These regulatory functions highlight the dynamic and essential role that blood plays in supporting overall health and ensuring the proper functioning of various systems within the body.
