If your muscles are not getting enough oxygen, your kidneys release a hormone, Erythropoietin (EPO), which stimulates the production of red blood cells by the bone marrow or vice versa. This is example of "     neutral feedback     positive feedback     negative feedback     all of these

A person who lives close to sea level and usually goes jogging in the morning. When that person runs at a place like Denver with high elevation she notices she isn't able to run as fast up in Denver as she usually does at home. She knows it is colder and there is less oxygen at high elevation than there is at his home. Why she feel like she didn't have the energy to keep up with her usual pace. a. her body wasnt able to begin glycolysis due to lack of oxygen b. her body was producing less ATP due to lack of oxygen  c. her body wasnt getting enough external heat input

Put the following events of hemostasis in the right order Thrombin converts fibrinogen into insoluble fibrin fibers Vascular spasm of injured blood vessel A blood clot forms by trapping erythrocytes in a fiber mesh. A platelet plug forms

Blood doping used to be an illegal practice where extra red blood cells are given to an athlete to increase oxygen carrying capacity immediately before a race.  Adverse (bad) effects of doping would include:       increased blood viscosity       increased blood pressure       increased work on the heart       all of these

An example of a positive feedback mechanism is blood clotting in which certain clotting factors active other factors until a plug forms to stop bleeding. Is this process involved in homeostasis? no, positive feedback mechanisms cannot regulate homeostasis no, it is not a negative feedback mechanism no, it does not fit into a classic "push-pull" action no, because it does not result in restoring blood volume O yes, because it is part of a bigger negative feedback mechanism to maintain optimal levels of blood volume. E O O O O C

There are two major coordinate all of the other organ systems in the human body. systems in the body that sensory hormones The system is comprised of the brain, spinal cord, and ions associated nervous The action of the nervous system allows the body to respond to both external and internal control nerves In addition, the the body's other systems, like maintenance of the male and female reproductive organs. system also regulates the functions of urinary stimuli This system's response, however, is slower due to the use of endocrine

Susie participates in BPCC's blood drive. Afterward, her red blood cell count is low and her she is slightly dehydrated. Her brain tells her bone marrow to produce more red blood cells and her kidneys to conserve water.  Susie’s bone marrow and kidneys are acting as what part of the homeostatic system?

Nitroglycerin has its positive cardiovascular effect by stimulating the production of which increased O CAMP: vasodilation O CGMP; vasodilation O DAG; Ca+2 release to cardiac cells DAG; cardiac cell growth CAMP; cardiac cell growth

SCIENCE, TECHNOLOGY,AND SOCIETY Hundreds of studies have linked smokingwith cardiovascular and lung disease. According to mosthealth authorities, smoking is the leading cause of preventable,premature death in the United States. What are somearguments in favor of a total ban on cigarette advertising?What are arguments in opposition? Do you favor or opposesuch a ban? Explain.

Which of these factors in active tissue does not lead to greater release of O₂ from hemoglobin? elevated temperature O increased acidity O All of the other choices lead to increased release of oxygen O elevated carbon dioxide In anemia, the blood has low levels of hemoglobin and carries less oxygen (this is TRUE). Question: Does anemic blood have reduced PO2 compared with the PO2 of blood with normal hemoglobin levels? O Yes O No
