Does decreased cardiac amount mean accumulation of blood to tissues/cells?
I'm trying to understand cardiac output. So, to my knowledge, decreased cardiac output = less blood being ejected by the heart/ventricles per minute, right?
What does that mean, specifically? Does that mean more blood is accumulated somewhere else? Like in the tissues/cells..lungs?
If blood is accumulated somewhere else...for example the kidneys ..doe
Three glands that make up one of the HPE Axes, and the hormones they secrete
feedback mechanisms, identify three glands that make up one of the HPE Axes, and the hormones they secrete. Give a detailed description of how the negative feedback mechanism works to maintain appropriate blood levels of the various hormones within your chose axis.
List histology tissue you go through from this list from outer to inner in order
I am stuck on this, new to A&P. Instructor said we need to list the tissues that a needle would go through from outer layer to inside layer from skin to scapula in order of their penetration through the layers. It is for extra credit, and with a condensed course of 16 weeks, into 6 weeks, I certainly could use it. He said the only help he would give us is that

Knowing that hawks see in the infrared region and identify prey by heat and dogs can hear a different range of sound, choose a special sense either vision and how cones or rods may need to be adapted or hearing and how higher frequencies could be heard.
Muscle stimulants are used to treat certain muscle diseases that are
Muscle stimulants are used to treat certain muscle diseases that are characterized by muscle weakness (decreased contraction of the muscle). Which of the two chemicals described below would be a good skeletal muscle stimulant?
Chemical A: binds to and blocks the action of acetylcholinesterase Chemical B: binds to and prevents the channels on the SR from
explain the interdependence between the C-V and resp systems in maintaining...?
Based on your knowledge of the cardiovascular and the respiratory systems, discuss how the two systems interact in order to maintain proper blood pH. In other words, explain the interdependence between the C-V and resp systems in maintaining blood pH. (Be sure to include not only resp mechanisms to control pH, but also how the heart will compensate when pH drops or CO2 is rising)
explain why the membrane potential between the axon hillock and axon either changed or did not change with threshold stimulus. Differences of 1.0 mV or less are not significant

1. Medulla oblongata integrates signal 2. ventricular myocardium beats with less force 3. sympathetic output decreases 4. arteriolar smooth muscle contracts 5. cardiac output decrease
Imagine you are watching the RADIO CITY MUSIC HALL ROCKETTES. They are known worldwide for their synchronized high kicks while standing in a single file line across the stage from left to right. List the muscles which must work to:
A. Flex the right thigh on the right hip; while at the same time flexing the right leg on the right thigh?
Please help with case study Sarah Mitchell is a 68-year-old female who is normally healthy. However, about five days ago she began to feel very fatigued and started to experience a burning and tingling sensation on her right thigh.
You ask to see the area and upon visual inspection you notice 3–4 small, red, swollen areas with vesicles on the posterior aspect of her

Your friend has just taken up running and is complaining of pain as he rubs dorsal regions of his feet. As an astute anatomy and physiology student, provide your friend with an explanation for his current condition.
Outline anatomical steps involved in reaching above your head to grab an apple.
In sequential fashion, outline the steps involved in reaching above your head to grab an apple from a branch. Include the roles of the special senses, central nervous system, peripheral nervous system, skin, muscles, and bones.
Muscle physiology- if injury was responsible for the development of soreness
In a fitness test a subject repeatedly stepped up using the right leg while the left leg was used to oppose the effect of gravity in the step down. Muscle pain was experienced several hours after the test. The soreness reached a peak in 1 to 2 days and persisted for about a week. The presences of proteins specific for muscle in the subject’s serum provided evidence for muscle cell i
A gastrocnemius muscle at optimal length, when maximally stimulated by a single
A gastrocnemius muscle at optimal length, when maximally stimulated by a single electrical stimulus, produces an isometric twitch tension of 80kg, and consumes 5 joules of energy above its basal energy consumption (measured by a calorimeter—includes all the energy used by the muscle as a result of that stimulus).If you then stretch the muscle (hyper-extend it) so that the same maxim

Which of the following is NOT characteristic of muscle spindles?
A. excite both alpha and gamma motor neurons B. eventually synapses with alpha motor neurons that innervate extrafusal muscle fibers C. have gamma motor neurons that innervate internal fibers D. maintain muscle tone at rest through tonic activity E. found at the junction of tendons
Evaluate and distinguish between the anatomical and functional divisions of the nervous system. Devise a detailed description of the structure and functions of each organelle in a typical neuron. Distinguish the locations and functions of the four neuroglial cells in CNS and the two neuroglial cells in PNS. Categorize the structure of the spinal cord to its function.
Part I – Sub-Saharan Safari A 51-year-old man named Robert Bragg reported to a hospital in the United Kingdom complaining of general malaise (discomfort), myalgia (muscle pain), fevers, headache, vomiting, and diarrhea. He complained that during the day he felt weak and tired; he was unsure if this was because his symptoms kept him awake at night, or if something el
The question is: Why there should be multiple "tubular structures in thyroid tissue." So not what all the structures are but why they are shaped this way and what purpose it serves.
There is a lot of News about Avandia , a drug for the treatment of Diabetes Mellitus. Avandia is an effective drug for controlling blood sugar levels in patients with type 2 or adult-onset diabetes. the drug works by making cells more receptive to insulin. However, the drug also has some particularly dangerous side effects, including heart failure, liver toxicity and blo
