| Question | Answer |
|---|---|
| Functions of the Blood | 1) Transportation 2) Regulation 3)Protection |
| Blood transports | Gases Nutrients Waste Hormones |
| Blood helps to regulate | pH Fluid Balance Body Heat |
| Blood acts to protect against | Disease Blood Loss |
| Blood cells are made in the spongy liquid center of the bones, | Bone marrow, from cells called stem cells. |
| There are 3 major kinds of blood cells. | Erythrocytes, thrombocytes or leukocytes |
| Carry oxygen to cells throughout the body. | Red blood cells (RBCs or erythrocytes) |
| Help make clots to plug up holes that form in blood vessels from injuries such as cuts, scrapes, or bruises. | Platelets (thrombocytes) |
| Help fight germs that get into the body. | White blood cells (WBCs or leukocytes) |
| Stem cells grow into different kinds of mature blood cells. These mature cells are released into the blood to do their work. T or F | True |
| Blood is composed of what 2 things: | Plasma 55% and Formed elements 45% |
| Formed elements in blood | Leukocytes, Platelets and Erythrocytes |
| Erythrocytes make up what majority of formed elements in blood | 99.1% |
| Protein and H20 make up what in the blood | Plasma |
| Percentage of water in plasma | 91% |
| 1) Water (91%) 2) Albumin 3) Clotting factors 4) Antibodies 5) Complement | Components of Plasma |
| Blood returns to the heart from the lungs via pulmonary veins | Oxygenated blood |
| Blood which returns to the heart via the venae cavae | Deoxygenated blood |
| The circuit that delvers oxygenated blood to the body and carries away waste | The Systemic Circuit |
| The circuit that eliminates carbon dioxide and oxygenates the blood | The Pulmonary circuit |
| Homeostasis | The tendency toward a relatively stable equilibrium between interdependent elements, especially as maintained by physiological processes. |
| A red protein responsible for transporting oxygen in the blood of vertebrates. Its molecule comprises four subunits, each containing an iron atom bound to a heme group. | Hemoglobin |
| 5 types of WBCs | Neutrophils Eosinophils Basophyls Lymphocytes Monocytes (aka “Macrophages”) |
| Hemostasis – preventing blood loss | Contraction of smooth muscle Formation of a platelet plug Formation of a blood clot |
| Blood Types | A-B-O Blood Type group The Rh Factor Others |
| Blood in Medicine | Whole Blood Transfusions Use of Blood Components Plasma Gamma Globulin Clotting Factor |
| Blood Studies | Hematocrit Hemoglobin Tests Blood Cell Counts Red Cell Counts White Cell Counts Platelet Counts Blood Smear Blood Chemistry Tests Coagulation Studies |
| Rh sensitization can occur during pregnancy if you are Rh-negative and pregnant with a developing baby (fetus) who has Rh-positive blood. This can cause the baby to have anemia, jaundice, or more serious problems. | This is called Rh disease. |
| Lymphocytes are white cells that are crucial to our immune systems. There are three main types known as T cells, B cells, and natural killer cells. | Lymphocytes |
| Lymphocytes are part of our immune defense and act to recognize antigens, produce antibodies, and destroy cells that could cause damage. | Lymphocytes |
