Question
Chapter 34.3, Problem 2CC
Summary Introduction
To determine:
What are the short-term changes in animal’s cardiovascular function that might facilitates use of skeletal muscle to escape dangerous situation.
Introduction:
Cardiovascular system is also as known as circulatory system. It is used to transport nutrients, oxygen, amino acids electrolytes, and hormones through blood and take out carbon dioxide and toxins from the body. It also helps in fighting diseases. It consists of blood and lymph. Blood is a fluid consists of red blood cell, white blood cell and plasma. Heart is a muscular tissue and is the main component of circulatory system.
Skeletal muscle is a voluntary muscle which is attached to bone and form nerve tissues, tendons, blood vessels, muscle tissue. It has ability to contract and relax and facilitate movement of body parts.

List at least one reason why arteriole vasoconstriction helps mammals function and survive:
How do hormones and nerves provide homeostatic regulation of blood flow as well as allow an animal to respond to stress?
Which of the following statements best describes the differences in the regulation of cardiac and skeletal muscle contraction?
The amount of contractile force actively generated by muscle cells is increased by stretch in skeletal muscle and decreased by stretch in cardiac muscle.
Cardiac muscle is stimulated by motor neurons and skeletal muscle by neurones from the autonomic nervous system.
Skeletal muscle contractile force is augmented by increasing the firing frequency of action potentials whereas cardiac muscle contractile force is enhanced by noradrenaline increasing calcium influx through ion channels.
Ryanodine receptors in skeletal muscle are opened by a mechanism that requires calcium influx whereas in cardiac muscle membrane depolarisation alone without calcium influx is sufficient to open ryanodine receptors.

- In conditioned athletes, the resting Heart Rate is generally much lower than in non-athletes. Why? a-because long-term exercise reduces Cardiac Output at rest to conserve energy b-because athletes have a smaller Stroke Volume at rest, causing Heart Rate to decrease as well c-because long-term exercise leads to increased vagal tone which slows Heart Rate d-because athletes have stronger ventricles and therefore a larger Stroke Volume at rest, so they require fewer bpm to achieve the same Cardiac Outputarrow_forwardDescribe two mechanisms by which the cardiac output of an animal’s heart can be adjusted and indicate which is more important for increasing cardiac output in mammals and which is more important in fish.arrow_forwardhow can swimming improves the cardiovascular fitness of a person?arrow_forward
- What are the important differences in the overall metabolic needs of a fish and a turtle and the ability of their circulatory systems to meet those needs? Select all that apply. Fish are less able to meet their metabolic needs than are turtles. Fish have a two-chamber heart (one atrium and one ventricle) and turtles have a three-chambered heart (two atria and one ventricle). Turtles are endothermic and fish are ectothermic Blood flows directly to other organs after being oxygenated in turtles, but return to the heart after being oxygenated in fish. Turtles have a double,-circuit circulatory system whereas fish have a single circulatory system.arrow_forwardThree circulatory systems of vertebrates are represented in the following diagram.

- Descrive (in the correct order) the sequence of the blood flow through a four chambered mammalian heart. Be sure to address the following: 1. Begin with the return of oxygen poor blood from the body. 2. Describe the chemical O2/ CO2 and glucose content of the blood in the key locations. 3. Describe the machanisms that regulate the functioning of the system to maintain homeostasis.arrow_forwardAn artificial heart works in closed loop by varying its pumping rate according to changes in signals from the recipient's nervous system. For feedback compensation design it is important to know the heart's open-loop transfer function. To identify this transfer function, an artificial heart is implanted in a calf while the main parts of the original heart are left in place. Then the atrial pumping rate in the original heart is measured while step input changes are effected on the artificial heart. It has been found that. in general, the obtained response closely resembles that of a second-order system. In one such experiment it was found that the step response has a %OS = 30% and a time of first peak 7, 127 sec (Nakamura, 2002). Find the corresponding transfer function. Aside from the corresponding transfer function, determine the following as well: delay time, rise time, settling time and steady state error if input is a step response.
