Study Notes
- Blood functions include regulation of body temperature, transportation of hormones and nutrients, and transportation of wastes, but not regulation of erythrocyte numbers.
- Erythrocytes, unlike white blood cells, lose their nucleus and organelles as they mature.
- Plasma does not come from stem cells in red bone marrow.
- Monocytes are not granulocytes.
- Thrombocytopenia is a blood disorder characterized by a reduction in the number of platelets.
- An individual whose blood sample reacts with anti-Rh and anti-A, but not anti-B, has A+ blood type.
- For muscle fiber contraction, cross-bridges must form between myosin and actin within a muscle cell
- Inflammation of the connective tissue surrounding a muscle bundle refers to tendinitis.
- A statement that is not true about muscle contraction is that it causes dehydration and ion imbalance.
- Actin and myosin filaments are located within a sarcomere.
- To check if athletes are producing ATP by anaerobic respiration, a trainer should look for lactic acid.
