Study Notes
Blood Functions
- Blood serves several important functions in the human body, including transporting oxygen, nutrients, and other substances to cells and tissues throughout the body.
- Blood plays a crucial role in the immune system, aiding in the defense against infections and diseases.
Plasma Functions
- Plasma is the liquid component of blood, making up about 55% of its total volume.
- Plasma functions include coagulation, immune defense, maintenance of osmotic pressure, acid-base balance, and transportation of nutrients.
Red Blood Cells (RBCs)
- RBCs, also known as erythrocytes, are primarily responsible for carrying oxygen from the lungs to the body's tissues.
- RBCs are small, round, and biconcave cells that contain hemoglobin, a red iron-rich protein that binds oxygen.
- Mature RBCs lack a nucleus, which allows them to efficiently release oxygen into the tissues.
- RBCs have a lifecycle of about 100-120 days, during which they carry oxygen and become more rigid before breaking down and being replaced by new RBCs.
White Blood Cells (WBCs)
- WBCs, or leukocytes, are part of the immune system and help fight infections.
- There are several types of WBCs, including lymphocytes, neutrophils, and monocytes, each with specific roles in immunity.
- Lymphocytes are produced by the bone marrow and are the primary cells responsible for fighting viral infections.
Platelets
- Platelets, also known as thrombocytes, are small cells that play a crucial role in blood clotting.
- When a blood vessel is injured, platelets clump together to form a plug, which helps prevent excessive bleeding.
- Platelets are produced by the bone marrow and have a lifespan of about 6 days.
Blood Types
- Blood types are determined by the presence or absence of specific proteins on the surface of RBCs, known as antigens.
- The four main blood types are A, B, AB, and O, and individuals may also have either Rh-positive or Rh-negative blood.
Blood Tests
- Blood tests are used to monitor various conditions and diseases, such as anemia and infections of the blood.
- A complete blood count (CBC) measures the number of RBCs, WBCs, and platelets, as well as hemoglobin and hematocrit levels.
- Abnormalities in these counts can indicate potential health issues and may require further investigation or treatment.
