• Mammary glands
• Produces female sex cells (oocytes) and hormones
• Supports developing embryo from conception to delivery
• Provides milk to nourish newborn infant
• Sexual intercourse
divides the ventral cavity and an inferior compartment known as abdominopelvic (peritoneal cavity).
1. separates cellular structures from the tissues and fluids outside the cell.
2. regulates the transport of substances into and out of the cell.
Rough Endoplasmic Reticulum
produces proteins that are secreted by the cell, incorporated into the plasma membrane, or used by lysosomes.
Smooth Endoplasmic Reticulum
1. synthesis of lipids and steroids
2. detoxification of poisons and drugs.
transport proteins from the golgi apparatus to the plasma (cell) membrane for cellular secretion.
1. neutralize toxins produced by cellular metabolism or taken in from the outside.
2. Break down fatty acids.
provides strength and flexibility to the cell and support for the various other organelles
1. produce microtubules for the cytoskeleton.
2. form the bases from which cilia and flagella are produced
3. form the mitotic spindle for mitosis
Net movement of a substance from a region of high concentration to a region of low concentration. (transport of oxygen and carbon dioxide across a cell membrane)
Simple diffusion of water across a selectively permeable membrane (movement of water into and out of cells to maintain osmotic balance)
same as simple diffusion, bu the transported substance must attach to a transport protein in the cell membrane. (transport of glucose into cells)
movement of an aqueous (water) solution along a pressure gradient, from an area of high hydrostatic pressure to an area of low hydrostatic pressure. (the movement of fluids out of capillary beds; the filtering of blood by the kidney)
movement of substances against a concentration gradient (from a region of low concentration to a region of high concentration). A transport protein molecule in the membrane is required. (the sodium-potassium pump)
vesicular (bulk) transport
movement across a membrane of large particles and macromolecules. The transported substance is enclosed by a vesicle.
endocytosis of undissolved particles such as bacteria, cell debris, or large proteins. (The ingestion of bacteria and viruses by macrophages and white blood cells)
endocytosis of liquid droplets with dissolved solutes. (absorption of some nutrients by cells in the small intestine)
endocytosis in which the transported substance must bind to a specific membrane receptor. (the transport of cholesterol into cells)
the secretion of a substance from a cell. (release of hormones by endocrine cells; release of neurotransmitter by nerve cells)
factors affecting diffusion
1. size of particles
2.temperature of the system
3. polarity of the substance being transported
A special case of simple diffusion. It talks about the diffusion of water through a selectively permeable membrane.
Under normal conditions, the cells in our body are exposed to ____________-. This means that the solute concentration of the cytoplasm is about the same of extracellular fluid.
functions of epithelial tissue.
4. sensory reception
1. Inner lining of blood vessels (endothelium)
2. Lining of body cavities (mesothelium)
1. epidermis of the skin
2. inner lining of esophagus
3. inner lining of vaginal canal
