How does the immune system aid in maintaining homeostasis withinthe human body? it regulates white blood cells during an infection. it causes an increase in heart rate during exercise. it signals sensory neurons to attack pathogens. it decreases blood pressure to reduce blood loss?
The immune system maintains homeostasis in the human body by recognizing and eliminating pathogens, regulating blood functions, and interacting with other systems through psychoneuroimmunology.
Explanation:The immune system plays a crucial role in maintaining homeostasis within the human body. It acts as a surveillance system that distinguishes between the body's own cells and foreign invaders. When a pathogen is detected, it activates the immune response, which involves the production of white blood cells to eliminate the threat. The system also helps in regulating functions such as blood clotting to prevent excessive blood loss and transporting disease-fighting agents to infection sites.
Blood regulation is another critical aspect where the immune system contributes to homeostasis by balancing pH levels, temperature, and osmotic pressure. Additionally, soluble signaling molecules mediate psychoneuroimmunology, the complex interaction between the immune system, nervous system, and endocrine system, for coordinated body regulation. This crosstalk ensures that during stressful periods, when the risk of infection may increase, the body can adjust immune responses accordingly with hormones like cortisol.
Lastly, blood cells like lymphocytes and phagocytes possess receptors for neurotransmitters indicating how interconnected the immune response is with other body systems. By functioning on 'autopilot', the immune system is an integral part of our survival, warding off pathogens and anticipating threats such as allergies or autoimmune diseases before they can disrupt homeostasis.
Which symptom is a result of taking diuretics?
A. nausea
B. diarrhea
C. loss of fluids
D. rapid weight loss
Final answer:
The symptom resulting from taking diuretics is loss of fluids, as diuretics increase urine production to reduce excess water and salt from the body, potentially leading to dehydration.
Explanation:
The symptom that is a result of taking diuretics is C. loss of fluids. Diuretics are medications designed to increase the amount of water and salt expelled from the body as urine. They are often prescribed for the treatment of high blood pressure, heart failure, kidney disorders, and other conditions. The primary function of diuretics is to eliminate excess water from the body, which can lead to a reduction in blood volume and lower blood pressure. One of the effects of diuretic use is increased urination, which can result in a significant loss of fluids and, if not carefully managed, may contribute to dehydration. Other potential effects include the loss of electrolytes like sodium and potassium, which may need to be monitored to prevent imbalances that can be harmful to the patient.
Which two fields of study to the principles of biomechanics come from
Final answer:
The principles of biomechanics are derived from physics and engineering, which provide the foundation for understanding forces, motion, and material properties as they apply to biological systems.
Explanation:
The principles of biomechanics primarily come from two interdisciplinary fields of study: physics and engineering. Biomechanics applies the principles of these fields to understand the motion and structure of living systems. Physics contributes the essential frameworks for understanding forces, motion, and the properties of materials, all of which are critical for analyzing biological systems. Engineering applies these principles to design systems and to analyze structural integrity, which is relevant in the context of biological tissues and orthopedic device design.
Hence, the correct answer is B. physics and engineering.

B. releases hormones to slow down heart rate to conserve energy C. releases hormones to slow down breathing rate to conserve energy
D. releases hormones to speed up glucose production for energy
Choose all that apply
Answer:
C.releases hormones to speed up glucose production for energy
Explanation:
During times of stress, the hypothalamus, a collection of nuclei that connects the brain and the endocrine system, signals the pituitary gland to produce a hormone, which in turn signals the adrenal glands, located above the kidneys, to increase the production of cortisol.

Which of the following methods is the most effective in determining muscular strength if you do not want to worry about selecting the wrong weight?
A. maxing out
B. absolute method
C. predicting 1 RM
D. calisthenic method
The answer is "c. predicting 1Rm ".
A repetition maximum (RM) is the most weight you can lift for a characterized number of activity developments. It is a decent proportion of your present quality dimension as you pursue your weight preparing program. For instance, a 10RM would be the heaviest weight you could lift for 10 back to back exercise redundancies.
Repetition maximum is often expressed as 1RM, or one-repetition maximum. This demonstrates the heaviest weight you can lift with most extreme exertion in a solitary repetition.
