• What are the importance of homeostasis?

  Maintaining internal balance is crucial for living organisms. Key points include:
  

  • Regulates body temperature for optimal physiological function.
  • Maintains appropriate pH levels essential for enzyme activity.
  • Balances nutrients and waste to prevent toxicity.
  • Supports overall health by adjusting to external changes.
  • Facilitates growth and development by providing a stable internal environment.

  Understanding homeostasis is vital for studying biology and health.

• What is an antagonistic effectors?

  
  
  
  
  Control by antagonistic effectors is sometimes described as “push- pull,” where the increasing activity of one effector is accompanied by decreasing activity of an antagonistic effector. This affords a finer degree of control than could be achieved by simply switching one effector on and off. 

• What is positive feedback?

  
  
  
  
  The action of effectors amplifies the changes that stimulated them. A thermostat that works by positive feedback, for example, would increase heat production in response to a rise in temperature. 
  - ex. Female reproductive system.

• Homeostasis is maintained by two general categories

  
  
  
  
  intrinsic- or “built into” the organs being regulated (such as molecules produced in the walls of blood vessels that cause vessel dilation or constric- tion) 
  
  
  
  
  
  extrinsic - as in regulation of an organ by the nervous and endocrine systems

• What are the primary tissues?

  1. Muscle
  2. Nerve
  3. Epithelial
  4. Connective

• What is the name of the grouping of the tissues?

  Organs

• What are the different parts of the neuron?

  1. Cell body
  2. Dendrites
  3. Axon

• What is excorine glands?

  Exocrine glands are specialized tissues that produce and secrete substances through ducts to the surface of an organ or tissue. They play a critical role in various bodily functions.
  

  • Examples include sweat, salivary, and digestive glands.
  • They secrete substances like enzymes, mucus, and hormones.
  • Unlike endocrine glands, they do not release hormones directly into the bloodstream.

• What are endocrine glands?

  Endocrine glands are specialized organs that produce and release hormones directly into the bloodstream. These hormones regulate various bodily functions, including:
  

  • Metabolism
  • Growth and development
  • Reproduction
  • Mood and stress response

  Examples include the thyroid, pancreas, and adrenal glands. Their proper functioning is crucial for maintaining homeostasis in the body.

• What do connective tissues consist of?

  Connective tissues are composed of various elements that support and bind other tissues. 
  1. Connective tissue proper
  2. Cartilages
  3. Bones
  4. Blood
