The principle of assimilation e. Which sequence correctly illustrates a negative feedback system? In addition to feedback mechanisms, what other control mechanism does the body use?
Which example best illustrates a feedforward mechanism? The release of thyroxin from the thyroid b. The production of red blood cells c. The replacement of skin cells d.
The excretion of bile from the gall bladder e. What is a predicted outcome of a severe homeostatic disruption? Physiology focuses exclusively on the study of human beings. Physiology examines the mechanisms of actions. Within physiology, structure and function are inseparable. The cell is the smallest unit capable of carrying out the processes associated with life.
The plasma membrane that surrounds each cell consists of non-fatty substances to allow for free movement of materials in and out of the cell. Enzymes are specialized proteins that speed up particular chemical reactions in the body. The three types of muscle tissue include skeletal, smooth, and connective. Epithelial sheets are layers of tightly joined cells that cover and line various parts of the body. Glands are epithelial tissue derivatives specialized for secreting.
Blood is classified as connective tissue.
Tendons and ligaments are classified as epithelial tissue. All endocrine glands contain ducts. The internal environment of a multicellular organism is the fluid surrounding cells, through which life-sustaining exchanges are made.
Homeostasis is a static state control system within the body. Long-term adaptations make the body more efficient in responding to an ongoing or repetitive challenge in homeostasis. Exercise initially disrupts homeostasis.
The respiratory system removes excess water, salt, acid, and other electrolytes from the plasma. Muscle tissue is the ultimate source of all red blood cells.
In contrast to the nervous system, the endocrine system regulates activities that require duration rather than speed, such as growth. The reproductive system is not essential for homeostasis, nor is it essential for survival of the individual.
Intrinsic, or local, controls are learned by an organ. A common example of positive feedback is the control of room temperature via a thermostat. The body uses feed forward mechanisms less frequently than feedback mechanisms.
Which numbered diagram shows the source of all blood cells? Which numbered diagram depicts a system vulnerable to atherosclerosis disease? Which numbered diagram depicts a system most negatively affected by a lack of dietary protein?
In response, this brain area activates nerve pathways that ultimately bring about involuntary, oscillating muscle contractions, which is commonly referred to as shivering.
REF: 1. How does the interface between the air and blood in the lungs work? ANS: The respiratory airways, which carry air from the outside into the lungs, branch extensively when they reach the lungs. Tiny air sacs cluster at the ends of the huge number of airway branches. Similarly, the vessels carrying blood into the lungs branch extensively and form dense networks of small vessels that encircle each air sac. The greater the surface area available for these exchanges, the faster O2 and CO2 can move between the air and the blood.
Distinguish between exocrine and endocrine glands. ANS: Exocrine glands secrete through ducts to the outside of the body or into a cavity that opens to the outside.
Examples are sweat glands and glands that secrete digestive juices. Endocrine glands lack ducts and release their secretory products, known as hormones, internally into the blood. For example, the pancreas secretes insulin into the blood, which transports this hormone to its sites of action throughout the body. Discuss the ethical concerns and political issues of the use of embryonic stem cells ESC. Opponents of using ESC are morally and ethically concerned because embryos are destroyed in the process of harvesting these cells.
Proponents argue that these embryos were destined to be destroyed anyway a decision already made by the parents of the embryos and that these stem cells have great potential for alleviating human suffering. As such, ESC science has become inextricably linked with stem cell politics. An annual anal Embed Size px. Start on. Show related SlideShares at end. WordPress Shortcode.
