General Blood refers to the overall composition and function of blood in the human body. Blood is a specialized bodily fluid that delivers necessary substances such as nutrients and oxygen to the cells and transports metabolic waste products away from those same cells.

Composition[edit]

Blood is composed of several key components:

Red blood cells (RBCs) - These cells are responsible for carrying oxygen from the lungs to the rest of the body and returning carbon dioxide to the lungs for exhalation.
White blood cells (WBCs) - These cells are part of the immune system and help the body fight infections and other diseases.
Platelets - These are small cell fragments that play a crucial role in blood clotting and wound healing.
Plasma - The liquid component of blood, plasma is a mixture of water, proteins, electrolytes, and other substances.

Functions[edit]

Blood performs many critical functions, including:

Transportation - Blood transports oxygen, nutrients, hormones, and waste products throughout the body.
Regulation - Blood helps regulate body temperature, pH levels, and fluid balance.
Protection - Blood contains cells and proteins that are essential for immune defense and clotting.

Blood Disorders[edit]

There are numerous disorders that can affect the blood, including:

Anemia - A condition characterized by a deficiency of red blood cells or hemoglobin, leading to fatigue and weakness.
Leukemia - A type of cancer that affects white blood cells, leading to an overproduction of abnormal cells.
Hemophilia - A genetic disorder that impairs the body's ability to make blood clots, leading to excessive bleeding.
Thrombocytopenia - A condition characterized by a low platelet count, which can lead to increased bleeding and bruising.

 == Composition ==
 Blood is composed of several key components:
-* '''[[Plasma (blood)|Plasma]]''': The liquid component of blood, in which the blood cells are suspended. Plasma is mostly water (about 90%) and contains proteins, glucose, mineral ions, hormones, carbon dioxide, and blood cells themselves.
+* [[Red blood cells]] (RBCs) - These cells are responsible for carrying oxygen from the lungs to the rest of the body and returning carbon dioxide to the lungs for exhalation.
+* [[White blood cells]] (WBCs) - These cells are part of the [[immune system]] and help the body fight infections and other diseases.
-* '''[[Red blood cell|Red Blood Cells (Erythrocytes)]]''': These cells are responsible for carrying oxygen from the lungs to the rest of the body and returning carbon dioxide from the body to the lungs.
+* [[Platelets]] - These are small cell fragments that play a crucial role in blood clotting and wound healing.
+* [[Plasma]] - The liquid component of blood, plasma is a mixture of water, proteins, electrolytes, and other substances.
-* '''[[White blood cell|White Blood Cells (Leukocytes)]]''': Part of the immune system, these cells help the body fight infections and other diseases.
-* '''[[Platelet|Platelets (Thrombocytes)]]''': These are cell fragments that play a crucial role in blood clotting and wound healing.
 == Functions ==
 Blood performs many critical functions, including:
-* '''Transportation''': Blood transports oxygen from the lungs to the cells of the body and carbon dioxide from the cells to the lungs. It also carries nutrients from the digestive tract to the cells and waste products from the cells to the kidneys.

+* [[Protection]] - Blood contains cells and proteins that are essential for immune defense and clotting.
-* '''Protection''': Blood contains white blood cells and antibodies that are essential for the immune response. It also contains platelets and clotting factors that help prevent blood loss from damaged vessels.

-* '''[[Anemia]]''': A condition characterized by a deficiency of red blood cells or hemoglobin, leading to fatigue and weakness.

-== Blood Typing ==
-Blood typing is the classification of blood based on the presence or absence of inherited antigenic substances on the surface of red blood cells. The most commonly known blood group systems are the [[ABO blood group system|ABO]] and [[Rh blood group system|Rh]] systems.

+== References ==
-Blood donation is a voluntary procedure that can help save lives. Donated blood is used for blood transfusions, which are critical in surgeries, trauma care, and for patients with certain medical conditions.
