Study Notes
Blood Composition
- Blood is mostly water (about 91%), the rest contains proteins, fats, minerals, and other substances.
- Red blood cells (erythrocytes), white blood cells (leukocytes) and platelets (thrombocytes) are the types of blood cells.
Blood Cell Production
- Blood cells are made in the bone marrow.
- The bone marrow contains stem cells which differentiate into the various blood cells (red blood cells, white blood cells and platelets).
Blood Function
- Blood transports oxygen and nutrients to cells.
- Blood carries waste products like carbon dioxide away from cells.
- Blood protects the body from pathogens.
- Blood clotting helps prevent excessive blood loss.
- Blood regulates temperature and water balance in the body.
Impact of Blood Malfunction
- The document suggests that the failure of blood to function properly could have serious consequences for the body.
Blood Composition
- Blood is primarily composed of plasma which is mostly water, with proteins, fats, minerals, and other crucial substances dissolved within it.
- Red blood cells (erythrocytes), white blood cells (leukocytes), and platelets (thrombocytes) are the main types of blood cells.
Blood Cell Production
- Blood cells are generated within the bone marrow, specifically the red bone marrow.
- Stem cells in the bone marrow undergo a process called differentiation to produce various blood cells, including erythrocytes, leukocytes, and thrombocytes.
Function of Blood
- Blood carries oxygen and vital nutrients to cells throughout the body.
- It also removes waste products like carbon dioxide from cells.
- The blood system provides protection by defending the body against pathogens (disease-causing organisms).
- Blood clotting helps prevent excessive blood loss from injuries.
- The blood plays a crucial role in temperature regulation, maintaining a stable body temperature, and regulating the water balance within the body.
Impact of Blood Malfunction
- A compromised blood function can lead to serious consequences for the entire body, as blood is vital for transporting oxygen, removing waste, and protecting against diseases.
- Blood clotting malfunction can lead to excessive bleeding.
- The text suggests exploring the implications of impaired blood function, hinting at the dire consequences that could arise if this crucial system malfunctions.
