Human Body Systems

Explanation:

  • Cardiac and skeletal muscle and cardiac(heart) are both striated in appearance, while smooth muscle isn't.
  • Both Cardiac and smooth muscle are automatic while skeletal muscle is deliberate.
  • Cardiovascular muscle is likewise an automatic muscle yet is progressively associated in structure to skeletal muscle, and is discovered uniquely in the heart.  
  • Smooth muscles move nourishment through the stomach related tract.
  • In one's eye the pupillary sphincter muscles is answerable for contracting the size of the student.
  • Smooth muscle developments keep up the supply routes' breadth. Smooth muscle controls wind stream in lungs.  
  • Heart muscles are striated not normal for smooth muscles.
  • Cardiovascular muscles are found in the heart dividers and aorta while smooth muscles are found in most of blood vessels and internal organs.

Answer:

Smooth muscles are type of tissue that are found in the walls of different organs like intestines, uterus and stomach,respiratory system etc.

Explanation:

The cell of smooth muscle is 3-10μm thick and 20-200μm long containing cytoplasm which is eosinophilic and have  myofilaments.

The nucleus is centrally located and is cigar like shape when it contracts.

The cells of smooth muscle is surrounded by connective tissue by basal lamina.

Role-

  • It plays important role in the ducts of exocrine gland.
  • It seals orifices like pyrolus,uterine wall and transport chyme through wave like contraction in intestinal tube.
  • Myofibroblasts is a special type of smooth muscle that produce connective tissue proteins like collagen,elastin.
