| Question | Answer |
|---|---|
| What kind of tissues is blood? | Connective tissue |
| What are the 5 roles of blood | 1. O2 + CO2 transport 2. Nutrients + waste products 3. Hormones from glands + Target tissues 4. WBCs to site of activity 5. Platelets to site of bleeding |
| What is liquid component of blood? | Plasma |
| What is the cellular component of blood (3) | 1. RBC 2. WBC 3. Platelets |
| What 5 things does plasma contain? | 1. water 2. proteins 3. electrolytes 4. nutrients 5. waste products |
| What is the liquid component of blood after a clot has formed? | serum |
| Hematopoiesis is? | Process of blood cell reproduction |
| What are 3 types of hematopoiesis? What cell do they make? | 1. Erythropoiesis; makes RBC 2. Leukopoiesis; makes WBS 3. Thrombopoiesis; makes platelets |
| Where does hematopoiesis occur in the fetus? (4) | 1. liver 2. spleen 3. thymus 4. red bone marrow |
| Where does hematopoiesis occur after birth? (1) | red bone marrow |
| Extramedullary hematopoiesis is? | Production in the liver and spleen during times of great need |
| What is the primary role of an erythrocyte? | To carry O2 |
| What allows an erythrocyte to be able to carry oxygen? | Hemoglobin |
| Where are erythrocytes formed? | In red bone marrow |
| What is the lifespan of a erythrocyte (RBC)? | 2-5 months (In most mammals) |
| How many hemes are in a hemoglobin? | 4 |
| How much Fe2+ does a heme unit contain? | 1 Fe2+ |
| What is the name given to a hemoglobin bound to O2? | Oxyhemoglobin |
| What is the name given to a hemoglobin bound to CO2? | carbaminohemoglobin |
| What substance binds to the heme of a hemoglobin? | oxygen |
| Define Senescense | the process of RBC aging |
| What is Hemolysis? | Process of erythrocyte destruction |
| What does extravascular hemolysis mean? | 90% of RBC removal occurs outside cardiovascular system in the spleen and liver |
| What cells perform phagocytosis? | Macrophages |
| How are RBC broken down? | RBC --> Heme --> Amino acids --> Iron |
| How is heme broken down? | Heme --> bilirubin --> liver --> excreted (urine, stool) |
| Where to platelets come from? | Large cells in the bone marrow called megakaryocytes |
| What is the function of a platelet? | To stop bleeding (Coagulation) |
| What is the main function of leukocytes (WBC)? | Immunity and protection from invaders |
| How do Leukocytes protect? (3) | 1. phagocytosis 2. production of antibodies 3. secretion of chemical substances that are toxic to pathogens or that attract WBC |
| What is the name given to a cell that has cytoplasmic granules? | Granulocyte |
| What are 3 granulocytes? | 1/ Neutrophils 2. Eosinophols 3. basophils |
| What is the name given to a cell that lacks granules? | Agranulocytes |
| What are 2 agranulocytes? | 1. lymphocytes 2. monocytes |
| What is the purpose of a lymphocyte? | To produce antibodies (B cells) or kill invaders (T cells) |
| What is the purpose of Monocytes? | Phagocytize invaders |
| What 2 parts make the lymphatic system? | 1. Lymphatic ducts + fluid (lymph) 2. Lymphoid organs + tissues |
| What are 4 functions of the lymphatic system? | 1. removal of excess tissue fluid 2. waste material transport 3. filtration of lymph 4. protein transport |
| What is lymph? | Transparent or translucent fluid |
| What makes lymph different from plasma? (6) | 1. few cells (aside from lymphocytes) 2. water 3. sugar 4. electrolytes 5. proteins found in blood plasma 6/ chylomicrons after a meal |
| Where does lymph fluid come from? | The capillary bed, it leaks out into the interstitium |
| What structure drains lymph? | Tiny lymphatic capillaries |
| What do lymphatic capillaries join into? | Lymphatic vessels (ducts) |
| What is lymph? | Transparent or translucent fluid |
| What makes lymph different from plasma? (6) | 1. few cells (aside from lymphocytes) 2. water 3. sugar 4. electrolytes 5. proteins found in blood plasma 6/ chylomicrons after a meal |
| Where does lymph fluid come from? | The capillary bed, it leaks out into the interstitium |
| What structure drains lymph? | Tiny lymphatic capillaries |
| Where do lymphocytes mature after leaving the bone marrow? | Primary lymphoid organs |
| What do lymphatic capillaries join into? | Lymphatic vessels (ducts) |
| Do lymphatic ducts have smooth muscle? Valves? | the ducts do not have smooth muscle, but do have valves |
| What do the lymph vessels form into? | Thoracic duct |
| What does the thoracic duct do with the lymph? | They empty it into the vena cava before it the duct enters the right atrium (Lymph is returned to plasma) |
| Where does lymph originally come from from? (Not capillary bed) | Plasma |
| Where do lymphocytes mature after leaving the bone marrow? | Primary lymphoid organs |
| What are 2 primary lymphoid organs? | 1. Thymus 2. Peyer's Patches/Bursa of Fabricius |
| What kind of cells does they Thymus make? | T cells |
| What kind of cells do the bursa of Fabricius make? | B cells |
| Where is the Thymus located? | Mediastinum of young animals |
| Where is the bursa located? | Only in birds! Round sac above cloaca |
| What happens to the thymus when an animal matures? | It gets replaced with fat |
| What is the name given to t lymphocytes residing in the thymus? | Thymocytes |
| Where are peyers patches found? | In the ileum |
| What are 3 secondary lymphoid organs | 1. spleen 2. lymph nodes 3. tonsils |
| What is the purpose fo the Lymph nodes? | to trap antigens and other foreign material carried in lymph |
| What is the purpose of tonsils | To prevent spread of infection into the respiratory and GI |
| What is the purpose of 2nd lymphoid organs | to tram and process antigens and mature lymphocytes |
| What is the purpose of tonsils | To prevent spread of infection into the respiratory and GI |
| What is the purpose of 2nd lymphoid organs | to tram and process antigens and mature lymphocytes |
| What are 2 purposes of the spleen? | 1. storage site for erythrocytes 2. Filters blood + lymog |
| What is white pulp? | Lymphoid tissue |
| what is red pulp? | Blood vessels, macrophages, sinuese to restore RBC |
| Can you live without a spleen? | Yes |
