Body cavities and organs

  • Cranial cavity. The brain.
  • Vertebral canal/spinal cavity. Spinal cord.
  • Thoracic cavity. Lungs, heart, esphagus, trachea, thymus.
  • Abdominal cavity. Stomach, liver, spleen, gallbladder, small and large intestines, and kidneys.
  • Pelvic cavity.
  • Mediastinum-lungs aren’t inside of it.
  • Pleural cavity- rt and left.
  • Pericardial cavity.
  • What is your chest cavity?

    The thoracic cavity (or chest cavity) is the chamber of the body of vertebrates that is protected by the thoracic wall (rib cage and associated skin, muscle, and fascia). The central compartment of the thoracic cavity is the mediastinum.

    Is the heart in the thoracic cavity?

    The thoracic cavity has three compartments: the mediastinum and two pleural cavities. The mediastinum is home to the heart, trachea, great vessels, and some other structures. The pleural cavities are on either side of the mediastinum and contain the lungs and the pleural linings.

    What organ does arteriosclerosis mainly affect?

    Atherosclerosis can affect the medium-sized and large arteries of the brain, heart, kidneys, other vital organs, and legs. It is the most important and most common type of arteriosclerosis, a general term for several diseases in which the wall of an artery becomes thicker and less elastic.

  • What system of the body does the spleen belong to?

    The lymphatic system is a network of very small tubes (or vessels) that drain lymph fluid from all over the body. The major parts of the lymph tissue are located in the bone marrow, spleen, thymus gland, lymph nodes, and the tonsils. The heart, lungs, intestines, liver, and skin also contain lymphatic tissue.

    Why do female rats have uterine horns rather than a simple uterus like humans?

    The vagina divides into two uterine horns that extend toward the kidneys. This duplex uterus is common in some animals and will accommodate multiple embryos (a litter). At the tips of the uterine horns are small lumpy glands called ovaries, which are connected to the uterine horns via oviducts.

    Is the spinal cord an organ or an organ system?

    Yes, it is part of an Organ System called the Nervous System. It includes the Brain, Spinal Cord, and all the Peripheral and Cranial Nerves.

    Is the trachea an organ or a tissue?

    The trachea is an important structure within your respiratory system, which is the organ system that delivers oxygen to your bloodstream. The trachea is a rigid tube that conducts air from your larynx to your bronchi.

    What is located in the dorsal cavity?

    The dorsal body cavity is located along the dorsal (posterior) surface of the human body, where it is subdivided into the cranial cavity housing the brain and the spinal cavity housing the spinal cord. The two cavities are continuous with one another.

    Which cavity contains the heart and lungs?

    Thoracic cavity: The chest; contains the trachea, bronchi, lungs, esophagus, heart and great blood vessels, thymus gland, lymph nodes, and nerve,. as well as the following smaller cavities: Pleural cavities: Surround each lung. Pericardial cavity: Contains the heart.

    What are the three sections of the small intestine of a rat?

    Rat Duodenum Tissue Sections. Three major regions comprise the small intestine: the duodenum, jejunum, and ileum.

    What is found in the pelvic cavity?

    The pelvic cavity is a body cavity that is bounded by the bones of the pelvis. Its oblique roof is the pelvic inlet (the superior opening of the pelvis). Its lower boundary is the pelvic floor. The pelvic cavity primarily contains reproductive organs, the urinary bladder, the pelvic colon, and the rectum.

    Where the heart is located?

    The heart is a muscular organ about the size of a fist, located just behind and slightly left of the breastbone. The heart pumps blood through the network of arteries and veins called the cardiovascular system.

    What cavity are the kidneys located in?

    Organs of the abdominal cavity include the stomach, liver, gallbladder, spleen, pancreas, small intestine, kidneys, large intestine, and adrenal glands.

    What organs are in the thoracic cavity of a pig?

    Fetal Pig Dissection: Cervical Region and Thoracic Cavity Organs

  • diaphragm. – location: large flat muscle dividing thoracic cavity from abdominopelvic cavity.
  • cervical region. – contains organs of respiratory and digestive system, spinal cord, and glands.
  • thoracic cavity.
  • larynx.
  • trachea.
  • thymus gland.
  • thyroid gland.
  • right and left lungs.
  • Which cavity contains the spinal cord?

    In the posterior (dorsal) cavity, the cranial cavity houses the brain, and the spinal cavity (or vertebral cavity) encloses the spinal cord. Just as the brain and spinal cord make up a continuous, uninterrupted structure, the cranial and spinal cavities that house them are also continuous.

    How many cavities are in the human body?

    Humans have four body cavities: (1) the dorsal body cavity that encloses the brain and spinal cord; (2) the thoracic cavity that encloses the heart and lungs; (3) the abdominal cavity that encloses most of the digestive organs and kidneys; and (4) the pelvic cavity that encloses the bladder and reproductive organs.

    What are the main organs in the chest cavity?

    The essential organs contained within the thoracic cavity are the lungs, the heart, part of the esophagus, the trachea, the thymus gland and the thoracic duct. There are lymph nodes within the thoracic cavity, as well as numerous blood vessels and nerves.

    Which bones make up the thoracic cage?

    The bones that create the architecture of the thoracic cage include the sternum, the ribs, and the thoracic vertebrae. The sternum: The sternum is a flat, long bone that forms the medial and anterior part of the thoracic cage. It has three parts: Manubrium: The manubrium forms the upper part of the sternum.

    Where is the thoracic cavity located in the body?

    Thoracic cavity, also called chest cavity, the second largest hollow space of the body. It is enclosed by the ribs, the vertebral column, and the sternum, or breastbone, and is separated from the abdominal cavity (the body’s largest hollow space) by a muscular and membranous partition, the diaphragm.

    What is the definition of pleural cavity?

    The pleural cavity is the thin fluid-filled space between the two pulmonary pleurae (known as visceral and parietal) of each lung. A pleura is a serous membrane which folds back onto itself to form a two-layered membranous pleural sac.
