  • Answer: The visceral membrane is a type of serous membrane, which covers the outer layer of organs (such as the intestines). It secretes small amounts of a serous fluid, which reduces friction between organs and other structures.
  • Answer: a membrane is made up of phospholipid molecules and rests on the outside of animal cells
    It is the outer layer of a cell that holds the entire cell intact.
  • Answer: Membranes are one of endless examples in biology of how structure equals function. If membranes require their structure be formed of specifically amphipathic lipids, this must be directly related to overall membrane function.

    The primary lipid components of membranes are phospholipids. Phospholipids consist of two hydrophobic ("water fearing") fatty acid tails attached to a hydrophillic ("water loving") phosphate head. Because their fatty acid tails are poorly soluble in water, phospholipids spontaneously form bilayers in aqueous solutions, with the hydrophobic tails buried in the interior of the membrane and the polar head groups exposed on both sides, in contact with the aqueous solution. This amphipathic structure of phospholipid bilayers forms a stable barrier between two aqueous compartments and represent the basic structure of all biological membranes.

    This structure directly relates to membrane function of forming a selectively permeable barrier between cells or between organelles within cells. The membrane is selectively permeable because only lipid soluble molecules and small uncharged molecules (such as water, carbon dioxide, molecular oxygen, ethanol, etc) may pass freely. Large polar molecules and ions require special transport proteins to cross the membrane and thus allow the cell to monitor what and how much of these molecules it is letting in or out at a given time.

    In summary, the amphipathic structure of phospholipids allow membranes to form a stable selectively permeable lipid barrier between aqueous compartments within/ between cells.
  • Answer: yes it can, but other sugars that are more complex like cellulose or starch cant
  • Answer: The respiratory membrane is formed by a combination of the walls ofalveoli and walls of capillaries. It consists of type 1 alveolarcells, a basement membrane, capillary endothelium, alveolarepithelium and macrophages.
  • Answer: The Respiratory membrane: The wall of the alveoli are composed primarily of a single layer of squamous epithelial cells, called type I cells, surrounded by a flimsy basement membrane. See page 815 anatomy and physiology 8th
  • Answer:
    1. The nuclear membrane is a thin membrane covering an animal cell. It holds in the cytoplasm, which in turn contains the organelles and nucleus of the cell. The cell membrane also allows the exchange of nutrients and oxygen/CO2.

  • Answer: The serous membrane contains the epithelial layer and the connective tissue layer.

    The epithelial layer produces cells that produce lubricating serious fluid. The Connective tissue later houses blood vessels and nerves and serves as the "binding layer" for the serous membrane to adhere to organs and other structures in the body.
  • Answer: The average thickness of respiratory membrane is 0.2 Mm
  • Answer: the respiratory membrane consists of an alveolar type I cell, an endothelial cell of a capillary, and their fused basement membranes
  • Answer: it is a barrier across which gases are excahnged betwween alveolar air and the blood. it helps prevent each alveolus from collapsing as air moves in and out during respiration
  • Answer: The perimetrium is essentially a coat to the uterus. It is theouter serosa layer of the uterus and it is part of the visceralperitoneum membrane.
  • Answer: Squamous cells and capillaries
  • Answer: The tympanic membrane (eardrum) separates the external ear from the middle ear

  • Answer: # The clear, yellowish fluid portion of blood, lymph, or intramuscular fluid in which cells are suspended. It differs from serum in that it contains fibrin and other soluble clotting elements.# Blood plasma.# Medicine. Cell-free, sterilized blood plasma, used in transfusions.# Protoplasm or cytoplasm.# The fluid portion of milk from which the curd has been separated by coagulation; whey.# Physics. An electrically neutral, highly ionized gas composed of ions, electrons, and neutral particles. It is a phase of matter distinct from solids, liquids, and normal gases.
  • Answer: Plasma is a part of blood that is yellowish in color. Its job is tohold the blood cells in suspension.
  • Answer: Irritablity is the ability to respond to stimuli and convert it to nerve impulses. Conductivity is the ability to transmit that impulse.
  • Answer: a. The clear, yellowish fluid portion of blood, lymph, or intramuscular fluid in which cells are suspended. It differs from serum in that in contains fibrin and other soluble clotting elements.b. Bood plasma
  • Answer: A respiratory membrane should be healthy.
  • Answer: Perichondrium
  • Answer: The nucleus is surrounded by a nuclear envelope composed of two membranes. The nuclear envelope is dotted with thousands of nuclear pores, which allow material to move into and out of the nucleus. Like messages, instructions, and blueprints moving in and out of a main office, a steady stream of proteins, RNA, and other molecules move through the nuclear pores to and from the rest of the cell. --Biology textbook

  • Answer:
    A mucous membrane is a layer of epithelial tissue which lines an area of the body which comes into contact with air. Mucous membranes are moist because of the presence of glands which secrete a thick fluid known as mucus, and they are important for a number of bodily functions. Mucous membranes line the urogenital tract, digestive tract, and respiratory tract, with one of the more well known mucous membranes being the lining of the interior of the nose.

    The moisture found in a mucous membrane acts to protect the body by creating a barrier and preventing the inside of the body from drying out. Mucus also traps pathogens, dirt, and particulate matter so that they can be sequestered and eliminated by the body. The nose is particularly famous for this, using mucus as a barrier between many harmful substances and the respiratory tract. Some sections of mucous membrane also have small hairs known as cilia which act as traps, and can move to push things across the surface of the membrane.
  • Answer: All cells have a membrane that distinguishes their internal contents from the surrounding fluid or tissue. Remember, smaller entities such as virus or prions are not cells, but rather just protein complexes.
  • Answer: is formed by the alveolar and capillary walls and their fusedbasement membranes
  • Answer: Basically, swelling of the membrances in the body. The symptoms ofwhich are redness, swelling, increase in temperature, decrease infunction, and maybe some itchiness.
