Study Notes
Bone Marrow
- Bone marrow is a primary lymphoid organ.
- It produces red blood cells in adults.
- It contains yellow marrow for lipid storage.
DNA Replication
- DNA polymerase is involved in the replication of DNA.
- RNA polymerase, DNA ligase, DNA helicase, and Topoisomerase are not involved in DNA replication.
Apoptosis
- Characteristics of apoptosis include cell shrinkage, DNA fragmentation, plasma membrane blebbing, and caspase activation.
- Apoptosis does not involve an inflammatory response.
Respiratory System
- In chronic obstructive pulmonary disease (COPD), residual volume is increased.
- Tidal volume, vital capacity, inspiratory reserve volume, and expiratory reserve volume are not increased in COPD.
Vitamins and Coagulation
- Vitamin K is essential for the synthesis of clotting factors.
- Vitamins A, B12, C, and D are not involved in clotting factor synthesis.
Blood Circulation
- The hepatic portal vein transports blood from the gastrointestinal tract to the liver.
Bone Cells
- Osteoclasts are primarily involved in bone resorption.
- Osteoblasts, chondrocytes, fibroblasts, and myocytes are not involved in bone resorption.
Blood Cells
- Eosinophils are a type of granulocyte.
- Lymphocytes, monocytes, erythrocytes, and thrombocytes are not granulocytes.
Hormones and Calcium Regulation
- Parathyroid hormone increases blood calcium levels.
- Insulin, glucagon, calcitonin, and thyroxine do not increase blood calcium levels.
Kidney Structure and Function
- Bowman's capsule is the structure responsible for the filtration of blood in the kidney.
- The loop of Henle, proximal convoluted tubule, distal convoluted tubule, and collecting duct are not involved in blood filtration.
